Abstract

An adapter fitting for the selective connection of a heater to a single or double-tube heating installation has a housing (2) in which there are two channels (3, 4) through which the heating medium is taken during operation from the heating installation to the heater or from the latter. In each of these channels there is a shut-off valve (26 or 27). In addition there is a connecting channel (5) connecting the two channels (3, 4) in which there is a regulating and shut-off valve (29). The two shut-off valves (26, 27) have closing components (24, 25) operating in a straight line and in a common plane bounded by the axes of the two connectors (10, 11) by which the fitting is connected to the heater. A closable drain aperture (34) opens into the atmosphere from at least one of these connectors (10, 11) for the purposes of emptying the heater when the shut-off valves (26, 27) are closed without interfering with the operation of the rest of the installation. To this end the two shut-off valves (26, 27) can be operated independently of the regulating and shut-off valve (29), and the drain aperture (34) can also be closed independently of these valves.

Description

Die Erfindung bezieht sich auf eine Adapterarmatur zum wahlweisen Anschluß eines mit einem Heizkörperventil versehenen Heizkörpers an die Zulauf- und Rücklaufrohrleitung einer Einrohr- oder Zweirohrheizanlage, mit einem Gehäuse, in welchem zwei Kanäle vorgesehen sind, von welchen der eine einen Stutzen zum lösbaren Anschluß der Zulaufrohrleitung mit einem Stutzen zum lösbaren Anschluß der Einlaßöffnung des Heizkörpers oder einer zu diesem führenden Armatur verbindet, wogegen der andere Kanal einen Stutzen zum lösbaren Anschluß der Rücklaufrohrleitung mit einem weiteren Stutzen zum lösbaren Anschluß der Auslaßöffnung des Heizkörpers oder einer damit verbundenen Armatur verbindet, und in jedem dieser Kanäle ein Absperrventil vorgesehen ist, und wobei ein die beiden Kanäle verbindender Verbindungskanal vorhanden ist, in welchem ein Regulier- und Absperrventil liegt, wobei die beiden Absperrventile voneinander und vom Regulier- und Absperrventil unabhängig betätigbar sind.The invention relates to an adapter fitting for the optional connection of a radiator provided with a radiator valve to the inlet and return pipe of a single-pipe or two-pipe heating system, with a housing in which two channels are provided, one of which is a connector for detachable connection of the inlet pipe with a connector for the detachable connection of the inlet opening of the radiator or a fitting leading to it, whereas the other channel connects a socket for the detachable connection of the return pipe with another socket for the detachable connection of the outlet opening of the radiator or an associated fitting, and in each of these channels, a shut-off valve is provided, and there is a connecting channel connecting the two channels, in which a regulating and shut-off valve is located, the two shut-off valves actuating one another and independently of the regulating and shut-off valve are cash.

Solche Adapterarmaturen sind bekannt (DE-A-3,934.837). Sie bilden einerseits ein Anschlußstück, mit welchem ein Heizkörper beliebiger Bauart, z.B. ein Platten- oder Gliederheizkörper, je nach den vorliegenden Gegebenheiten an die Rohrleitungen einer Einrohrheizanlage oder einer Zweirohrheizanlage angeschlossen werden kann. Anderseits ermöglichen es solche Armaturen, das Versorgungssystem zu ändern, also von einer Einrohrheizanlage auf eine Zweirohrheizanlage oder umgekehrt überzugehen, auch wenn die Heizkörper bereits montiert sind. Die beiden Absperrventile dienen hiebei dazu, den Heizkörper ohne Behinderung der Funktion der Anlage absperren zu können, sei es, weil der betreffende Raum, in welchem der Heizkörper steht, nicht beheizt werden soll, sei es zwecks Austausch des Heizkörpers od.dgl. Da ein Verbindungskanal zwischen den beiden Kanälen vorhanden ist, so ist dies auch bei einer Einrohrheizanlage möglich, da dieser Verbindungskanal bei geöffnetem Regulier- und Absperrventil einen Bypass zum Rohrnetz bildet. Durch dieses Ventil ist also nicht nur eine Umstellung von Einrohrbetrieb auf Zweirohrbetrieb bzw. umgekehrt möglich, sondern auch im Einrohrbetrieb eine Einstellung der Heizwasserverteilung zwischen Heizkörper und Bypass.Such adapter fittings are known (DE-A-3,934,837). On the one hand, they form a connection piece with which a radiator of any type, e.g. a panel or sectional heater, depending on the circumstances, can be connected to the pipes of a single-pipe heating system or a two-pipe heating system. On the other hand, such fittings make it possible to change the supply system, i.e. to switch from a single-pipe heating system to a two-pipe heating system or vice versa, even if the radiators are already installed. The two shut-off valves serve to be able to shut off the radiator without obstructing the function of the system, be it because the room in which the radiator is located should not be heated, be it for the purpose of replacing the radiator or the like. Since there is a connecting channel between the two channels, this is also possible with a single-pipe heating system, since this connecting channel forms a bypass to the pipe network when the regulating and shut-off valve is open. With this valve it is not only possible to switch from one-pipe operation to two-pipe operation or vice versa, but also to adjust the heating water distribution between the radiator and bypass in single-pipe operation.

Bei der erwähnten bekannten Konstruktion sind die beiden Absperrventile als Hähne ausgebildet, welche von der Frontseite der Armatur, d.i. in der Regel die dem zu beheizenden Raum zugewendete Seite des Heizkörpers, her betätigbar sind. Diese Konstruktion hat den Nachteil, daß die Absperrventile schwer zugänglich sind, wenn die Armatur - aus was für Gründen auch immer - um 180° verdreht angeschlossen werden muß. Außerdem ist nachteilig, daß bei Lösen der Verbindung zwischen der Armatur und dem Heizkörper das Wasser aus diesem ausrinnt, da ja in der Regel die Abströmöffnung für das Heizmedium aus diesem Heizkörper an einer tiefgelegenen Stelle desselben angeordnet ist.In the known construction mentioned, the two shut-off valves are designed as taps which can be actuated from the front of the fitting, ie as a rule the side of the radiator facing the space to be heated. This construction has the disadvantage that the shut-off valves are difficult to access when the valve - for what Reasons always - must be connected rotated by 180 °. It is also disadvantageous that when the connection between the fitting and the radiator is loosened, the water runs out of it, since the outflow opening for the heating medium from this radiator is generally arranged at a lower point thereof.

Die Erfindung setzt sich zur Aufgabe, diese Nachteile zu vermeiden und eine Armatur der eingangs beschriebenen Art so zu verbessern, daß die Betätigung der Absperrventile stets möglich ist und daß eine Möglichkeit für ein kontrolliertes Entleeren des Heizkörpers in jeder Lage desselben gegeben ist, ohne den Betrieb der übrigen Heizkörper der Anlage zu beeinträchtigen. Die Erfindung löst diese Aufgabe dadurch, daß die beiden Absperrventile geradlinig verstellbare Verschlußkörper haben, daß die Verstellrichtungen dieser Verschlußkörper in einer gemeinsamen Ebene liegen, die aufgespannt ist von den Achsen der beiden mit dem Heizkörper bzw. seiner Armatur zu verbindenden Stutzen, und daß von zumindest einem der zum Heizkörper bzw. seiner Armatur führenden Stutzen eine unabhängig von den Absperrventilen und vom Regulier- und Absperrventil verschließbare Entleerungsöffnung ins Freie führt. Im Sinne der Erfindung sind somit die beiden Absperrventile von den beiden Seiten der Armatur her betätigbar, so daß es egal ist, in welcher Lage die Armatur an die Rohrleitungen für die Heizmittelversorgung angeschlossen wird. Mittels der Entleerungsöffnung kann der Heizkörper bei geschlossenen Absperrventilen kontrolliert entleert werden, das durch diese Entleerungsöffnung abströmende Wasser läßt sich problemlos mit einem geeigneten Gefäß auffangen oder auf andere geeignete Weise entfernen. Es muß bei der Montage der Armatur bzw. des daran angeschlossenen Heizkörpers lediglich Bedacht darauf genommen werden, daß eine Entleerungsöffnung an jener Seite liegt, die der tiefergelegenen Abströmöffnung aus dem Heizkörper zugeordnet ist. Da in der Regel eine bestimmte Heizkörperanordnung gewünscht ist, bedeutet dies, daß das Vorhandensein einer Entleerungsöffnung diesem Wunsch Rechnung tragen muß. Für aus dem Fußboden nach oben austretende Rohrleitungen bietet die Erfindung den Vorteil, daß die Armatur in beiden möglichen Lagen montierbar ist, so daß durch Wahl dieser Lage eine Anpassung der Lage der Entleerungsöffnung an die Lage der Abströmöffnung des Heizkörpers gegeben ist. Für aus der Wand austretende Rohrleitungen kann die Konstruktion problemlos mit je einer Entleerungsöffnung an jedem der beiden Stutzen versehen werden, oder es werden zwei Konstruktionsvarianten vorgesehen, bei deren einer die Entleerungsöffnung an den linken Stutzen angeschlossen ist, bei der anderen an den rechten.The invention has for its object to avoid these disadvantages and to improve a valve of the type described above so that the actuation of the shut-off valves is always possible and that there is a possibility for a controlled emptying of the radiator in any position of the same, without the operation the other radiators in the system. The invention solves this problem in that the two shut-off valves have rectilinearly adjustable closure bodies, that the adjustment directions of these closure bodies lie in a common plane spanned by the axes of the two connecting pieces to be connected to the heating element or its fitting, and that at least one of the connecting pieces leading to the radiator or its armature leads to the drainage opening that can be closed independently of the shut-off valves and the regulating and shut-off valve. In the sense of the invention, the two shut-off valves can thus be actuated from the two sides of the fitting, so that it does not matter in which position the fitting is connected to the pipes for the heating medium supply. The radiator can be emptied in a controlled manner by means of the emptying opening when the shut-off valves are closed; the water flowing out through this emptying opening can be easily collected with a suitable vessel or removed in another suitable manner. When installing the fitting or the radiator connected to it, it is only necessary to take care that an emptying opening is located on the side which is assigned to the lower-lying outflow opening from the radiator. Since a specific radiator arrangement is generally desired, this means that the presence of an emptying opening must take this wish into account. For pipelines emerging from the floor upwards, the invention offers the advantage that the fitting can be mounted in both possible positions, so that by selecting this position, the position of the emptying opening is adapted to the position of the outflow opening of the radiator. For pipelines emerging from the wall, the construction can easily be provided with a drain opening on each of the two nozzles, or two construction variants are provided, one of which has the drain opening on the left nozzle is connected, the other to the right.

Für eine gattungsfremde Einrichtung (US-A-4,469.131) ist es bekannt, in einem Gehäuse, das im wesentlichen H-Form aufweist, zwei Ventile anzuordnen, welche den Zustrom in zwei nach oben gerichtete Stutzen regeln. Diese beiden Ventile sind jedoch nicht unabhängig voneinander betätigbar, da beide Verschlußkörper auf eine gemeinsame Spindel aufgesetzt sind. Dadurch lassen sich zwar unterschiedliche Stellpositionen der Verschlußkörper erzielen, jedoch nicht unabhängig voneinander, so daß die Funktionsweise, welche durch den Erfindungsgegenstand erzielbar ist, mit der bekannten Vorrichtung nicht erreicht werden kann.For a non-generic device (US-A-4,469,131), it is known to arrange two valves in a housing which is essentially H-shaped, which regulate the inflow into two upwardly directed nozzles. However, these two valves cannot be operated independently of one another, since both closure bodies are placed on a common spindle. As a result, different adjustment positions of the closure bodies can be achieved, but not independently of one another, so that the mode of operation which can be achieved by the subject of the invention cannot be achieved with the known device.

Bei einer weiteren gattungsfremden Einrichtung (US-A-4,129.149) ist ein einziger Stutzen des Gehäuses für den Anschluß des Heizkörpers vorgesehen und es ist das Heizkörperventil im Gehäuse der Adapterarmatur angeordnet. Eine solche Einrichtung läßt sich nicht im Sinne der Erfindung verwenden.In another non-generic device (US-A-4,129,149), a single connecting piece of the housing is provided for the connection of the radiator and the radiator valve is arranged in the housing of the adapter fitting. Such a device cannot be used in the sense of the invention.

Gemäß einer Weiterbildung der Erfindung liegt auch die Achse der Entleerungsöffnung in der erwähnten Ebene, was auch diese Öffnung in allen möglichen Lagen der Armatur problemlos zugänglich macht.According to a development of the invention, the axis of the emptying opening lies in the plane mentioned, which also makes this opening easily accessible in all possible positions of the fitting.

Gemäß einer bevorzugten Ausführungsform der Erfindung ist die Anordnung so getroffen, daß die Achse der Entleerungsöffnung koaxial liegt zur Achse des zugehörigen Absperrventils. Dies erleichtert die Herstellung und ermöglicht eine platzsparende und materialsparende Konstruktion.According to a preferred embodiment of the invention, the arrangement is such that the axis of the drain opening is coaxial with the axis of the associated shut-off valve. This simplifies production and enables a space-saving and material-saving construction.

Zweckmäßig liegen im Rahmen der Erfindung die beiden Verstelleinrichtungen und die Achse der Entleerungsöffnung zueinander koaxial, vorzugsweise horizontal. Die horizontale, koaxiale Lage ermöglicht es, die bekannte H-förmige Grundform der Armatur beizubehalten, obwohl im Prinzip auch Abweichungen davon möglich wären.In the context of the invention, the two adjusting devices and the axis of the emptying opening are expediently coaxial, preferably horizontal. The horizontal, coaxial position makes it possible to maintain the familiar H-shaped basic shape of the valve, although in principle deviations from it would also be possible.

Die Erfindung ermöglicht es aber auch, einen weiteren Nachteil der eingangs beschriebenen bekannten Konstruktion zu beseitigen. Dieser Nachteil besteht darin, daß bei einer Einrohrheizanlage das Wasser auch bei geschlossenem Heizkörperventil in den Heizkörper wirbelt und dadurch diesen mehr oder weniger erwärmt, auch wenn das im Verbindungskanal angeordnete Regulier- und Absperrventil voll offen ist. Zur Beseitigung dieses Nachteiles ist gemäß der Erfindung die Anordnung so getroffen, daß der Ventilsitz zumindest des einen Absperrventiles in einem normal auf die zugehörige Verstellrichtung liegenden Wandabschnitt einer den zugehörigen Kanal durchsetzenden Wand angeordnet ist, die eine Umlenkfläche für das aus der zugehörigen Rohrleitung zuströmende Heizmedium bildet, welche dieses Heizmedium in Richtung zum Verbindungskanal lenkt. Diese Umlenkung des Heizmediums begünstigt die Einleitung des Heizmediums in den Verbindungskanal, so daß bei den oben beschriebenen Bedingungen nur unwesentliche oder gar keine Heizmediumanteile zum Heizkörper strömen. Um diesen Vorteil für die beiden möglichen Montagelagen der Armatur aufrechtzuerhalten ist es zweckmäßig, beide Absperrventile in der beschriebenen Weise auszubilden.However, the invention also makes it possible to eliminate a further disadvantage of the known construction described at the outset. This disadvantage is that in a single-pipe heating system, the water swirls into the radiator even when the radiator valve is closed, thereby heating it more or less, even if the regulating and shut-off valve arranged in the connecting channel is fully open. To eliminate this disadvantage, the arrangement is such that the valve seat of at least one shut-off valve is arranged in a wall section lying normal to the associated adjustment direction of a wall penetrating the associated channel, which forms a deflection surface for the heating medium flowing from the associated pipeline , which directs this heating medium towards the connecting channel. This deflection of the heating medium favors the introduction of the heating medium into the connecting channel, so that, under the conditions described above, only insignificant or no heating medium components flow to the radiator. To maintain this advantage for the two possible mounting positions of the valve it is expedient to design both shut-off valves in the manner described.

Eine besonders zweckmäßige Ausbildungsform der Erfindung besteht darin, zumindest einen der beiden Verschlußkörper als mit Gewinden geführte Voreinstellkörper auszubilden, um die Absperrfunktion mit der Voreinstellfunktion kombinieren zu können. Dieser Vorteil läßt sich zusätzlich zu den oben beschriebenen Vorteilen erzielen, ohne letztere zu schmälern.A particularly expedient embodiment of the invention consists in designing at least one of the two closure bodies as a presetting body guided with threads in order to be able to combine the shut-off function with the presetting function. This advantage can be achieved in addition to the advantages described above without reducing the latter.

Bei der Ausführungsform nach den Fig.1 bis 4 hat die Adapterarmatur 1 ein Gehäuse 2, das im wesentlichen eine H-Form aufweist. Die beiden vertikalen Schenkel des H bilden zwei parallel zueinander verlaufende Kanäle 3,4 und der horizontale Schenkel des H ist durch einen die beiden Kanäle 3,4 verbindenden Verbindungskanal 5 gebildet. Die beiden unteren Enden der Kanäle 3,4 sind jeweils mit einem Stutzen 6 bzw. 7 zum lösbaren Anschluß an die Rohrleitung einer Einrohrheizanlage oder an die beiden Rohrleitungen einer Zweirohrheizanlage versehen. Hiezu sind die beiden Stutzen 6,7 mit Gewinden 8 versehen. Es sei angenommen, daß der Stutzen 6 den Zulauf und der Stutzen 7 den Ablauf für das Heizmedium bildet, was durch Pfeile 9 angedeutet ist.In the embodiment according to FIGS. 1 to 4, the adapter fitting 1 has a housing 2 which is essentially H-shaped. The two vertical legs of the H form two channels 3, 4 running parallel to one another and the horizontal leg of the H is formed by a connecting channel 5 connecting the two channels 3, 4. The two lower ends of the channels 3, 4 are each provided with a connector 6 or 7 for detachable connection to the pipeline of a single-pipe heating system or to the two pipes of a two-pipe heating system. For this purpose, the two nozzles 6, 7 are provided with threads 8. It is assumed that the socket 6 forms the inlet and the socket 7 forms the outlet for the heating medium, which is indicated by arrows 9.

Die beiden nach oben weisenden Enden der Kanäle 3,4 sind mit Stutzen 10 bzw. 11 zum lösbaren Anschluß an den nicht dargestellten Heizkörper oder einer zu ihm führenden Armatur 12 versehen. Um hiebei Ungenauigkeiten in der Montage aufnehmen zu können, sind die beiden Stutzen 10,11 mit ebenen Stirnflächen 13 ausgebildet, auf welche Flachdichtungen 14 aufgelegt sind, welche durch die anzuschließenden Bauteile 15 der Armatur od.dgl. zusammengedrückt werden. Hiezu sind diese Bauteile mit Gewinden 16 versehen, auf welche Überwurfmuttern 17 aufschraubbar sind, welche die Stutzen 10,11 mit Spiel umgeben. Die Überwurfmuttern 17 stützen sich gegen Widerlager 18 ab, welche von Sprengringen gehalten sind, die in die Außenwand der Stutzen 10,11 eingelassen sind.The two upward-facing ends of the channels 3, 4 are provided with sockets 10 and 11 for releasable connection to the radiator (not shown) or a fitting 12 leading to it. In order to be able to accommodate inaccuracies in the assembly, the two connecting pieces 10, 11 are designed with flat end faces 13, on which flat seals 14 are placed, which or the like due to the components 15 of the fitting to be connected. be squeezed together. For this purpose, these components are provided with threads 16, onto which union nuts 17 can be screwed, which the Neck 10.11 surrounded with play. The union nuts 17 are supported against abutments 18 which are held by snap rings which are embedded in the outer wall of the connecting pieces 10, 11.

Jeder Kanal 3,4 ist von einer Wand 19 bzw. 20 durchsetzt, welche die einander zugewendeten Enden der Stutzen 6,10 bzw. 7,11 miteinander verbindet. Jede dieser Wände 19,20 hat einen mittigen Abschnitt 21, welcher in Achsrichtung der Kanäle 3 bzw. 4 bzw. normal zur Achse des Verbindungskanales 5 verläuft. Jeder Abschnitt 21 hat eine kreisförmige Durchgangsöffnung 22, welche einen Ventilsitz 23 für einen Verschlußkörper 24 bzw. 25 eines Absperrventiles 26 bzw. 27 bildet, mit welchem der betreffende Kanal 3 bzw. 4 abgeschlossen werden kann. Die Verstellrichtung jedes der Verschlußkörper 24,25 ist hiebei in Achsrichtung des Verbindungskanales 5 bzw. normal auf die Achsen der Kanäle 3,4 und liegt in einer Ebene, welche aufgespannt ist durch die Achsen der beiden Stutzen 10,11, welche zum Anschluß des Heizkörpers dienen. Die Verstellrichtungen der beiden Verschlußkörper 24,25 sind koaxial zueinander und sind ferner koaxial zur Verstellrichtung des Verschlußkörpers 28 eines Regulierund Absperrventiles 29. Der Verschlußkörper 28 arbeitet mit einem Ventilsitz 30 zusammen und ist mit einer als Drosselkörper 31 wirkenden Verlängerung versehen, die an ihrem Umfang mit seitlichen Abflachungen 32 oder Aussparungen versehen ist, z.B. mit entsprechenden Abfräsungen. Dieses Regulier- und Absperrventil 29 dient im Einrohrbetrieb als Voreinstellung für die über den als Bypass zum Heizkörper wirkenden Verbindungskanal 5 strömende Heizmediummenge, da der Verbindungskanal 5 im Nebenschluß zum Heizkörper liegt, oder als Absperrung für den Verbindungskanal 5, wenn der Heizkörper im Zweirohrsystem betrieben wird.Each channel 3, 4 is penetrated by a wall 19 and 20, respectively, which connects the ends of the connecting pieces 6, 10 and 7, 11 facing each other. Each of these walls 19, 20 has a central section 21 which runs in the axial direction of the channels 3 or 4 or normal to the axis of the connecting channel 5. Each section 21 has a circular passage opening 22, which forms a valve seat 23 for a closure body 24 or 25 of a shut-off valve 26 or 27, with which the relevant channel 3 or 4 can be closed. The adjustment direction of each of the closure bodies 24, 25 is in the axial direction of the connecting channel 5 or normal to the axes of the channels 3, 4 and lies in a plane which is spanned by the axes of the two connecting pieces 10, 11 which are used to connect the heating element to serve. The adjustment directions of the two closure bodies 24, 25 are coaxial to one another and are also coaxial to the adjustment direction of the closure body 28 of a regulating and shut-off valve 29. The closure body 28 works together with a valve seat 30 and is provided with an extension acting as a throttle body 31, which extends along its circumference lateral flats 32 or recesses is provided, for example with appropriate millings. This regulating and shut-off valve 29 is used in one-pipe operation as a presetting for the amount of heating medium flowing via the connecting duct 5 acting as a bypass to the radiator, since the connecting duct 5 is shunted to the radiator, or as a shut-off for the connecting duct 5 if the radiator is operated in a two-pipe system .

Weiters hat das Gehäuse 2 einen mit dem Abschnitt des Kanales 4 im Bereich des Stutzens 11 in Verbindung stehenden Stutzen 33 eine Entleerungsöffnung 34, durch welche der Heizkörper bei geschlossenen Absperrventilen 26,27 entleert werden kann, wenn - wie dies oben angenommen wurde - der erwähnte Abschnitt des Kanales 4 mit dem Ablaufstutzen des Heizkörpers in Verbindung steht, so daß im wesentlichen das gesamte im Heizkörper befindliche Wasser aus dem Heizkörper abgelassen werden kann. Diese Entleerungsöffnung 34 ist durch einen Stopfen 35 verschließbar, welcher in ein Gewinde 36 des Stutzens 33 einschraubbar ist, jedoch in seinem inneren Teil zumindest eine Abflachung 37 aufweist, um den Stopfen 35 zwecks Entleerung des Heizkörpers nicht ganz aus dem Stutzen 33 herausschrauben zu müssen und dennoch eine kontrollierte Entleerung des Heizkörpers zu sichern. Eine Kappe 38 ist auf ein Außengewinde des Stutzens 33 aufgeschraubt und dichtet diesen Stutzen ab.Furthermore, the housing 2 has a connecting piece 33 connected to the section of the channel 4 in the area of the connecting piece 11 and has an emptying opening 34 through which the heating element can be emptied when the shut-off valves 26, 27 are closed, if - as was assumed above - the mentioned Section of the channel 4 is connected to the drain connector of the radiator, so that essentially all of the water in the radiator can be drained from the radiator. This drain opening 34 can be closed by a plug 35, which can be screwed into a thread 36 of the socket 33, but has at least one flattened portion 37 in its inner part, in order not to have to completely unscrew the plug 35 from the socket 33 in order to empty the radiator and nevertheless a controlled emptying of the Secure radiator. A cap 38 is screwed onto an external thread of the connector 33 and seals this connector.

Der Stopfen 35 dient zugleich als Führung für die Verstellbewegung des Verschlußkörpers 25. Hiezu hat letzterer einen mit einem Außengewinde versehenen Flansch 39, der in das gleiche Gewinde des Stutzens 33 eingeschraubt ist wie der Stopfen 35. Dieser Flansch 39 bildet mit einem Fortsatz eine Spindel 40, welche den Stopfen 35 nach außen durchsetzt und an ihrem äußeren Ende mit einem Vierkant 41 od.dgl. zum Ansatz eines Werkzeuges versehen ist. Dieser Vierkant 41 sitzt in einer entsprechenden Ausnehmung 42 des Stopfens 35, die so groß ist, daß der Ansatz des Werkzeuges, z.B. eines Vierkant-Steckschlüssels, nach Abnahme der Kappe 38 problemlos möglich ist. Dadurch läßt sich der Verschlußkörper 25 des Absperrventiles 27 problemlos von der Seite der Armatur 1 in die Absperrlage (Fig.4) bringen, wobei der Flansch 39 mit dem Verschlußkörper 25 auf der Spindel 40 gleitet. Ebenso sind beliebige Zwischenstellungen möglich, wobei der Verschlußkörper 25 einen Voreinstellkörper bildet.The plug 35 also serves as a guide for the adjustment movement of the closure body 25. For this purpose, the latter has an externally threaded flange 39 which is screwed into the same thread of the socket 33 as the plug 35. This flange 39 forms a spindle 40 with an extension , which passes through the plug 35 to the outside and at its outer end with a square 41 or the like. is provided for the approach of a tool. This square 41 sits in a corresponding recess 42 of the plug 35 which is so large that the attachment of the tool, e.g. a square socket wrench, after removing the cap 38 is easily possible. As a result, the closure body 25 of the shut-off valve 27 can easily be brought into the shut-off position from the side of the fitting 1 (FIG. 4), the flange 39 sliding with the closure body 25 on the spindle 40. Any intermediate positions are also possible, the closure body 25 forming a presetting body.

Von der gegenüberliegenden Seite der Armatur 1 her sind der Verschlußkörper 24 des Absperrventiles 26 und der Verschlußkörper 28 samt Drosselkörper 31 des Regulier- und Absperrventiles 29 betätigbar. Hiezu ist der Verschlußkörper 24 des Absperrventiles 26 in ein Innengewinde 43 eines mit dem Verbindungskanal 5 koaxialen Stutzens 44 des Gehäuses 1 eingeschraubt, welcher Stutzen 44 nach der anderen Seite weist als der Stutzen 33 für die Entleerungsöffnung 34. Der Verschlußkörper 24 hat an seiner äußeren Stirnfläche eine Vertiefung 45, z.B. einen Innensechskant, zum Ansatz eines geeigneten Werkzeuges, mit welchem der Verschlußkörper 24 verdreht und somit in Achsrichtung des Verbindungskanales 5 verstellt werden kann. Damit läßt sich das Absperrventil 26 schließen bzw. es läßt sich dieses Ventil in Zwischenstellungen bringen, wobei der Verschlußkörper 24 einen Voreinstellkörper bildet. Dadurch ist eine beliebige Voreinstellung für die dem Heizkörper zuzuführende Heizflüssigkeit möglich.The closure body 24 of the shut-off valve 26 and the closure body 28 together with the throttle body 31 of the regulating and shut-off valve 29 can be actuated from the opposite side of the fitting 1. For this purpose, the closure body 24 of the shut-off valve 26 is screwed into an internal thread 43 of a connector 44 of the housing 1 coaxial with the connecting channel 5, which connector 44 points to the other side than the connector 33 for the drain opening 34. The closure body 24 has on its outer end face a recess 45, e.g. an internal hexagon, for the attachment of a suitable tool with which the closure body 24 is rotated and thus can be adjusted in the axial direction of the connecting channel 5. The shut-off valve 26 can thus be closed or this valve can be brought into intermediate positions, the closure body 24 forming a presetting body. This allows any presetting for the heating fluid to be supplied to the radiator.

Zugleich bildet der Verschlußkörper 24 mit einer mittigen Bohrung 46 eine Führung für einen eine Spindel 47 bildenden, nach außen weisenden Fortsatz des Verschlußkörpers 28 des Regulier- und Absperrventiles 29. Hiezu hat dieser Verschlußkörper 28 ein Außengewinde, welches in ein entsprechendes Gewinde 48 hinter dem Ventilsitz 30 einschraubbar ist. An ihrem äußeren Ende trägt die Spindel 47 eine Vertiefung 49, z.B. einen Innensechskant, für den Ansatz eines entsprechenden Werkzeuges, z.B. eines Steckschlüssels. Eine auf ein Außengewinde des Stutzens 44 aufschraubbare Kappe 50 schützt die beschriebenen Bauteile gegen unbeabsichtigte bzw. unbefugte Verstellung.At the same time, the closure body 24 with a central bore 46 forms a guide for an extension of the closure body 28 of the regulating and shut-off valve 29 which forms a spindle 47 and points outwards. For this purpose, this closure body 28 has an external thread which fits into a corresponding thread 48 behind the valve seat 30 can be screwed in. At its outer end, the spindle 47 carries a recess 49, for example an internal hexagon, for the attachment of a corresponding tool, for example a socket wrench. One that can be screwed onto an external thread of the connector 44 Cap 50 protects the components described against unintentional or unauthorized adjustment.

Nach Abnahme der Kappe 50 läßt sich das Regulier- und Absperrventil 29 problemlos in die Offenstellung (Fig.2) bzw. in jedwede gewünschte Zwischenstellung bringen. In den Zwischenstellungen bildet der Drosselkörper 31 je nach der eingestellten Lage eine mehr oder weniger große Drosselung des Durchflußquerschnittes beim Ventilsitz 30, so daß die jeweils gewünschte Drosselung problemlos einstellbar ist.After removing the cap 50, the regulating and shut-off valve 29 can easily be brought into the open position (FIG. 2) or into any desired intermediate position. In the intermediate positions, the throttle body 31 forms a more or less large throttling of the flow cross-section at the valve seat 30, depending on the set position, so that the throttling desired in each case can be set without problems.

Die Zugänglichkeit für die Verstellung aller Ventile 26,27,29 sowie des Stopfens 35 für die Entleerungsöffnung 34 von den beiden Seiten der Armatur 1 her ermöglicht es, die entsprechenden Handgriffe unabhängig davon durchzuführen, welche der beiden Einbaulagen für die Armatur 1 vorliegt.The accessibility for the adjustment of all the valves 26, 27, 29 and the plug 35 for the drain opening 34 from the two sides of the fitting 1 makes it possible to carry out the corresponding operations regardless of which of the two installation positions for the fitting 1 is present.

Die Anordnung der Stutzen 6,7 nach den Fig.1 bis 4 entspricht einer Ausführungsform für aus dem Fußboden herausgeführte Rohrleitungen. In diesem Fall liegen die Achsen der Stutzen 6,7 koaxial mit jenen der Kanäle 3,4 und zumindest im wesentlichen vertikal, wogegen die Achse des Verbindungskanales 5 horizontal liegt. Liegt jedoch ein Anschluß an aus der Wand herausgeführte Rohrleitungen vor, so findet eine der Ausführungsformen nach den Fig.5-7 Verwendung. Gemäß Fig.5 sind die beiden Stutzen 6,7 als 90°-Krümmer ausgebildet, die beide nach der gleichen Richtung weisen. Um auch bei einer solchen Konstruktion eine Entleerung des Heizkörpers für beide möglichen Lagen seiner Abströmöffnung zu sichern, sind zwei Entleerungsöffnungen 34 vorgesehen, jeweils eine für einen der beiden zum Heizkörper führenden Stutzen 10,11. Die zweite, in Fig.5 nicht sichtbare Entleerungsöffnung muß nicht unbedingt im Bereich des horizontalen Stutzens 44 angeordnet werden, sie kann vielmehr auch direkt am nach oben weisenden Stutzen 10 vorgesehen sein. Eine andere Möglichkeit besteht darin, zwei unterschiedliche Typen einer solchen Adapterarmatur 1 auf Lager zu halten, von denen die eine Type die Entleerungsöffnung 34 wie in Fig.5 dargestellt aufweist, also entsprechend der Ausführungsform nach Fig.1, wogegen die andere Type die Ventile 26,27,29 und die Entleerungsöffnung 34 in Bezug auf die beiden Stutzen 6,7 spiegelbildlich versetzt hat.The arrangement of the nozzles 6, 7 according to FIGS. 1 to 4 corresponds to an embodiment for pipelines leading out of the floor. In this case, the axes of the nozzles 6, 7 are coaxial with those of the channels 3, 4 and at least substantially vertical, whereas the axis of the connecting channel 5 is horizontal. However, if there is a connection to pipelines leading out of the wall, one of the embodiments according to FIGS. 5-7 is used. 5, the two nozzles 6, 7 are designed as 90 ° elbows, both of which point in the same direction. In order to ensure that the radiator is emptied for both possible positions of its outflow opening even with such a construction, two emptying openings 34 are provided, one for each of the two connecting pieces 10, 11 leading to the radiator. The second emptying opening, which is not visible in FIG. 5, does not necessarily have to be arranged in the region of the horizontal connecting piece 44, but rather can also be provided directly on the connecting piece 10 pointing upward. Another possibility is to keep two different types of such an adapter fitting 1 in stock, of which one type has the emptying opening 34 as shown in FIG. 5, that is to say in the embodiment according to FIG. 1, whereas the other type has the valves 26 , 27, 29 and the emptying opening 34 has a mirror image offset with respect to the two connecting pieces 6, 7.

Eine solche Ausführung in zwei Typen ist ersparbar, wenn gemäß Fig.6 der Stutzen 6 bzw.7 an seinem unteren Ende als T-Stück 51 ausgebildet ist, welches zwei nach vorne und hinten weisende Öffnungen 52,53 einer Querbohrung 54 aufweist. Die beiden Querbohrungen 54 der beiden Stutzen 6,7 liegen zueinander parallel. Die jeweils nicht benützte Öffnung 53 wird durch eine Kappe 55 dichtend abgeschlossen.Such an embodiment in two types can be spared if, according to FIG. 6, the connecting piece 6 or 7 is formed at its lower end as a T-piece 51, which has two openings 52, 53 of a transverse bore 54 pointing forwards and backwards. The two transverse bores 54 of the two nozzles 6.7 lie parallel to each other. The respectively unused opening 53 is sealed off by a cap 55.

Eine Variante zu Fig.6 besteht gemäß Fig.7 darin, daß an die beiden Stutzen 6,7, welche zweckmäßig bei dieser Ausführungsform nur sehr kurz ausgebildet sind, jeweils ein 90°-Krümmer 56 schwenkbar angeschlossen ist. Dies kann z.B. mittels eines Gewindes 57 geschehen, wobei eine Ringdichtung 58 für die nötige Dichtheit sorgt. Bei der Montage der Adapterarmatur werden die beiden Krümmer 56 in die jeweils gewünschte Richtung gedreht. Auf diese Weise kann, ebenso wie bei der Ausführungsform nach Fig.6, mit einer einzigen Entleerungsöffnung 34 das Auslangen gefunden werden.According to FIG. 7, a variant to FIG. 6 consists in that a 90 ° elbow 56 is pivotally connected to the two connecting pieces 6, 7, which are expediently designed to be very short in this embodiment. This can e.g. happen by means of a thread 57, an annular seal 58 providing the necessary tightness. When installing the adapter fitting, the two elbows 56 are rotated in the desired direction. In this way, just as in the embodiment according to FIG. 6, the length can be found with a single emptying opening 34.
