Description

Die Erfindung betrifft eine Vorrichtung zur Verteilung eines strömenden Mediums auf verschiedene Rohrleitungen, die Gewähr dafür bietet, daß etwa die gleiche Menge des Mediums zu den betreffenden , Leitungen, unabhängig von den Druckschwankungen in diesen, strömt. Die Erfindung ist dadurch gekennzeichnet, daß jede Rohrleitung mit einem Ventil versehen ist, das aus einem Gehäuse und einem verschiebbaren Kolben besteht, dessen eine Endfläche unter der Einwirkung des Druckes des Mediums in der Leitung hinter dem Ventil steht, während auf die gegenüberliegende Endfläche eine Druckfeder und auch ein für alle Ventile gleicher, Druck wirkt, und daß ferner das Gehäuse mit einem Durclitrittskana#I für das Medium versehen ist, dessen Querschnitt von der axialen Stellung des Kolbens abhängt.The invention relates to a device for distributing a flowing medium to different pipelines which provides assurance that about the same amount of flow of the medium to the respective, lines, regardless of the pressure fluctuations in these. The invention is characterized in that each pipeline is provided with a valve consisting of a housing and a displaceable piston, one end face of which is under the action of the pressure of the medium in the line behind the valve, while a compression spring is applied to the opposite end face and also a same for all valves, acting pressure, and that, furthermore, the housing having a Durclitrittskana # I is provided for the medium, whose cross-section is dependent on the axial position of the piston.

In anderem Zusammenhang, z. B. für die Anlaufbelastung in der Drubkleitung von Kreiselpumpen, ist die Verwendung eines druckabhängigen selbsttätigen Absperrorgans bekannt, bei dem mittels eines verschiebbaren Kolbens, dessen Endfläche unter der Druckeinwirkung des Durchflußmediums steht und auf dessen gegenüberliegender Endfläche eine Druckfeder wirkt, der Querschnitt des Durchflußkanals für das Medium in Abhängigkeit von diesem Druck verändert wird. Dieses Absperrorgan wird unmittelbar nur durch den Druck des Mediums in der vor ihm liegenden Leitung beeinflußt, während bei der Verteilungsvorrichtung nach der Erfindung für die Steuerung der Durchflußmenge der Druck des Mediums sowohl vor als auch hinter dem Ventil maßgebend ist.In another context, e.g. B. for the starting load in the Drubkleitung of centrifugal pumps, is the use of a pressure-dependent automatic shut-off device known, in which by means of a displaceable piston, the end face of which under the Pressure action of the flow medium is and on its opposite end face a compression spring acts, the cross section of the flow channel for the medium as a function is changed by this pressure. This shut-off device is only immediately through affects the pressure of the medium in the line in front of him, while at the Distribution device according to the invention for controlling the flow rate of the Pressure of the medium both upstream and downstream of the valve is decisive.

In den Zeichnungen ist eine beispielsweise Ausführungsform der Erfindung dargestellt. Es zeigt F i g.1 ein Ventil im mittleren Längsschnitt und F i g. 2 eine schematische Darstellung einer Kälteanlage mit der Verteilungsvorrichtung gemäß der Erfindung.An example embodiment of the invention is shown in the drawings. FIG. 1 shows a valve in the middle longitudinal section and FIG. 2 shows a schematic representation of a refrigeration system with the distribution device according to the invention.

Das Ventil 1 besteht aus einem zylinderförmigen Gehäuse 2 mit einer Bohrung für einen Kolben 3, der in dem Gehäuse verschiebbar ist und einen Durchtrittskanal 4 für ein strömendes Medium regelt. Die Endfläche 5 des Kolbens steht unter der Einwirkung einer Druckfeder 6 und eines Druckes eines Mediums, das dem Gehäuse durch eine Rohrleitung 7 zugeführt wird. Dieser letztgenannte Druck ist für alle Ventile gleich. Der Druck des strömenden Mediums in der Leitung 4 hinter dem Ventil wirkt auf die gegenüberliegende Endfläche 8 des Kolbens, was dadurch ermöglicht wird, daß der Raum in dem Gehäuse 2 an der Endfläche 8 mit der Leitung 4 über eine Leitung 9 verbunden ist. Wenn der Kolben keinen Druck erhält, liegt er gegen einen einstellbaren Anschlag 10 an. Mit 11 ist eine Dichtung bezeichnet.The valve 1 consists of a cylindrical housing 2 with a bore for a piston 3, which is displaceable in the housing and regulates a passage 4 for a flowing medium. The end face 5 of the piston is under the action of a compression spring 6 and a pressure of a medium which is fed to the housing through a pipe 7. This latter pressure is the same for all valves. The pressure of the flowing medium in the line 4 behind the valve acts on the opposite end face 8 of the piston, which is made possible by the fact that the space in the housing 2 is connected to the line 4 via a line 9 at the end face 8 . When the piston does not receive any pressure, it rests against an adjustable stop 10 . With 11 a seal is designated.

Die Einrichtung nach der Erfindung ist vorzugsweise für Kälteanlagen mit zwei und mehr Verdampfern bestimmt, und eine solche Anlage mit zwei Verdampfern 12, 13 ist in F i g. 2 gezeigt.The device according to the invention is preferably intended for refrigeration systems with two or more evaporators, and such a system with two evaporators 12, 13 is shown in FIG. 2 shown.

Ein Kältemittel wird von einer Pumpe 15 aus einem Behälter 14 durch die mit, V#nfilfii 1 ausgerüsteten Leitungen 4 zu den Veräämpleirn 12, 13 gepumpt. Die Verdampfer müssen häufig in der Lage sein, bei unterschiedlichen Verdampfungstemperaturen zu arbeiten (was in diesem Fall dasselbe ist wie bei unterschiedlichen Verdampfungsdrücken). Der Druck in dem Behälter 14 ist niedriger als in irgendeinem der Verdampfer. Der Druck (die Temperatur) in den Verdampfern wird durch Ventile 16 geregelt. Die Regelung erfolgt entsprechend dem erforderlichen Grad der Kühlung und wird durch öffnen odeV Drosseln des-Ventils 16 bewirkt, was von Hand oder selbsttätig durch einen Thermostaten erfolgen kann.A refrigerant is pumped by a pump 15 from a container 14 through the lines 4 equipped with V # nfilfii 1 to the Veräämpleirn 12, 13 . The evaporators often need to be able to operate at different evaporation temperatures (which in this case is the same as different evaporation pressures). The pressure in container 14 is lower than any of the evaporators. The pressure (temperature) in the evaporators is regulated by valves 16 . The regulation takes place according to the required degree of cooling and is effected by opening or throttling the valve 16 , which can be done manually or automatically by a thermostat.

Wenn eines der Ventile 16 gedrosselt wird, dann wächst der Widerstand in dem betreffenden Verdampferkreis, was, sofern das Ventil gemäß der Erfindung nicht eingebaut wäre, zur Folge hatte, daß die Menge des durch einen Kreis umlaufenden Kältemittels abnehmen würde, während die durch den zweiten Kreis umlaufende Menge zunehmen würde, da die - Gesamtmenge des umlaufenden Kältemittels nahezu gleichbleibend ist. Uni den Eintritt dieses Zustandes zu verhindern, wird der erhöhte Widerstand in dem gedrosselten Ventil 16 durch Verminderung des Widerstandes in irgendeinem anderen Teil des betreffenden Verdampferkreises kompensiert, so daß die durch ihn strömende Menge konstant gehalten wird. Dies geschieht durch weiteres Öffnen des dem betreffenden Kreis zugeordneten Ventils 1, dessen Widerstand somit verringert wird.If one of the valves 16 is throttled, the resistance in the evaporator circuit concerned increases, which, if the valve according to the invention were not installed, had the consequence that the amount of refrigerant circulating through one circuit would decrease while that through the second Circulating amount would increase because the - total amount of circulating refrigerant is almost constant. To prevent this condition from occurring, the increased resistance in the throttled valve 16 is compensated for by reducing the resistance in any other part of the evaporator circuit concerned, so that the amount flowing through it is kept constant. This is done by further opening the valve 1 assigned to the circuit in question, the resistance of which is thus reduced.

Bei Kälteanlagen, in denen das Kältemittel durch die Verdampfer mittels einer Pumpe in Umlauf gesetzt wird, war es bisher üblich, einen Behälter 14 und eine Pumpe15 für jeden Verdampfer vorzusehen, oder für jedes Verdampfersystem, das mit den gleichen Verdampfungstepperaturen arbeitete. Durch Anbringen des Ventils 1 gemäß der Erfindung wird die Anlage vereinfacht und gleichzeitig eine bessere Anpassung an die laufenden Temperaturanforderungen erzielt.In refrigeration systems in which the refrigerant is circulated through the evaporator by means of a pump, it has hitherto been customary to provide a container 14 and a pump 15 for each evaporator, or for each evaporator system that worked with the same evaporation devices. By attaching the valve 1 according to the invention, the system is simplified and at the same time a better adaptation to the current temperature requirements is achieved.
