Description
Die Erfindung bezieht sich auf eine Vorrichtung zum Ausgleich und Abdichten unrunder, muffenloser Rohre, vorzugsweise Steinzeugrohre mit einer Doppelmuffe aus flexiblem Kunststoff, in welche die mit einem elastischen Dichtungsring umlegten Rohrenden geschoben sind.The invention relates to a device for balancing and Sealing of out-of-round, socketless pipes, preferably stoneware pipes with a double socket made of flexible plastic, in which they were wrapped with an elastic sealing ring Pipe ends are pushed.
Das Maß des Ausgleichs durch ein elastisches Dichtungsmaterial ist nicht genau bestimmbar, insbesondere nicht bei größeren Rohrdurchmessern. Das gilt besonders für Steinzeugrohre, wo vor allen Dingen die unterschiedlichen Stärken der Rollringe, das Ausmaß der Unrundheit der Rohre, die ungenauen, wechselnden Spaltbreiten eine exakte Berechenbarkeit und damit eine sichere Zentrier- bzw. Ausgleichsmöglichkeit nicht möglich machen. Es fehlt an einer sicheren Größe, die diesen Nachteil beseitigte und den Ausgleich und damit die Dichtung in einen sicheren Griff brachte.The degree of compensation by an elastic sealing material is not precisely determinable, especially not with larger pipe diameters. That is true especially for clay pipes, where above all the different strengths the rolling rings, the extent of the out-of-roundness of the pipes, the imprecise, changing gap widths an exact calculability and thus a safe centering or compensation option not make it possible. It lacks a safe size that would overcome this disadvantage and brought the compensation and thus the seal into a safe grip.
Aufgabe der Erfindung ist es, bei der Vorrichtung der eingangs genannten Art die im Falle der Verwendung von Rollringen als Dichtungen bekanntermaßen bereits eintretende Wirkung der Rohrzentrierung und des Ausgleichs von Rohrunrundheiten zu verbessern und gleichzeitig mit den zur Wirkungsverbesserung vorgesehenen Mitteln einen auswechselbaren Mittelanschlag in der Muffe zu halten.The object of the invention is, in the device of the aforementioned Kind of already known in the case of using rolling rings as seals occurring effect of the pipe centering and the compensation of pipe irregularities to improve and at the same time with the means intended to improve the effectiveness to hold an interchangeable central stop in the socket.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß etwa in der Mitte der Doppelmuffe auf zwei gedachten, axialen Abstand von einander aufweisenden Kreisen jeweils mindestens drei zu einander versetzte, nach innen vorstehende, konische Nocken zum Zentrieren bzw. Vorzentrieren der Rohre und zum Halten eines Mittelanschlags für die eingeschobenen Rohrenden angebracht sind.This object is achieved in that, for example, in the Center of the double socket on two imaginary, axial distance from each other Circles in each case at least three offset, inwardly protruding, conical ones Cams for centering or pre-centering the pipes and for holding a central stop for the inserted pipe ends are attached.
Zweckmäßig ist dabei der Mittelanschlag, eine in den Spalt zwischen die Nocken 2 eingelegte, elastische oder plastische Ringscheibe. Dadurch wird die Bruchgefahr an den Stirnflächen der keramischen Rohre bei Biege- oder Längsbewegungen beseitigt und Ablagerungen im Rohrstoß verhindert durch ein allgemeines Maschinenelement (Ringscheibe), das zwischen ohnehin in der Muffe vorhandenen Vorsprüngen gehalten wird. In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.The central stop, one in the gap between, is useful the cams 2 inserted, elastic or plastic washer. This will make the Risk of breakage at the end faces of the ceramic tubes when bending or longitudinally moving eliminated and deposits in the pipe joint prevented by a general machine element (Washer), which is held between projections that are already present in the socket will. An exemplary embodiment of the invention is shown in the drawing.
Sie zeigt in der oberen Abbildung ein Schnittbild der vollständigen Doppelmuffe 1 bis 4 mit zwei eingerollten, ebenfalls geschnittenen Rohrenden 5 in schematischer Darstellung. Im einzelnen: die Doppelmuffe 1 mit Nocken 2, deren Aufgleitflächen angeschrägt sind, die die Abdichtung bewirkenden, hochelastischen Rollringe 3, die Ringscheibe 4, deren Aussparung in der von b gezeichneten, unteren Sicht zum Ausdruck gebracht ist.In the figure above, it shows a sectional view of the complete double socket 1 to 4 with two rolled, also cut pipe ends 5 in a schematic representation. In detail: the double sleeve 1 with cams 2, the sliding surfaces of which are bevelled, the sealing effect, highly elastic rolling rings 3, the washer 4, the recess of which is expressed in the bottom view drawn by b.
In dieser unteren Abbildung ist die Doppelmuffe 1 und 2 ohne Rollringe 3 und ohne eingeschobene Rohrenden 5 dargestellt. Die Ringscheibe 4 wird nach dem Einlegen in den freien Spalt zwischen den Nocken 2 um einen Winkel, in der Zeichnung a, gedreht und dient dann der Lagesicherung der Doppelmuffe mittig über den beiden Rohrenden.In this figure below, the double socket 1 and 2 is without rolling rings 3 and shown without inserted pipe ends 5. The washer 4 is after Insertion into the free gap between the cams 2 at an angle, in the drawing a, rotated and then serves to secure the position of the double socket in the middle of the two Pipe ends.
