Description

Rohreinbaustück veränderlicher Baulänge Die Erfindung betrifft die Gesamtaus-Bildung eines Rohreinbaüstücks mit veränderlicher Baulänge, bei dem ein elastischer Weichdichtungsring in einer Kammer so verformt wird, daß er alle Wege für den Durchtritt des Fludes absperrt; der dabei die Verdrehungsspannung aufnehmende metallische Dichtungsring wird damit zum starren Widerlager, über das sich beim Weiterdrehen der Überwurfmutter nunmehr ein geschlitzter Klemmkegel unbegrenzt festziehen kann.Pipe chock of variable overall length The invention relates to Overall formation of a pipe installation piece with variable overall length, in which a elastic soft sealing ring is deformed in a chamber so that it all ways shut off for the passage of the fluid; the one absorbing the torsional stress metallic sealing ring thus becomes a rigid abutment over which the Turning the union nut further, tighten a slotted clamping cone indefinitely can.

Man hat wohl schon solche Rohrkupplungen unter Benutzung entsprechender Elemente aufgebaut, dabei jedoch die Anpressung des geschlitzten Spannkegels über die Weichdichtung durchgeführt, wodurch diese übermäßig beansprucht wird, ohne daß der Klemmkegel mit Sicherheit zur Wirkung gelangt; andererseits ist dabei auch ein nicht durch die Weichdichtung abgeschlossener Weg um diese herum offen geblieben.One has probably already had such pipe couplings using appropriate ones Elements built up, but the pressure of the slotted clamping cone over the soft seal carried out, whereby this is excessively stressed without the clamping cone will certainly take effect; on the other hand, there is also a Path not closed by the soft seal remained open around this.

In der beiliegenden Zeichnung ist ein Ausführungsbeispiel der Erfindung im Schnitt nach dem Zusammenbau, aber vor dem Anziehen der Verschraubung wiedergegeben.In the accompanying drawing is an embodiment of the invention shown in section after assembly, but before tightening the screw connection.

Auf das Außengewinde a des Grundkörpers e ist die mit entsprechendem Innengewinde ausgerüstete Überwurfmutter b aufgeschraubt, die einen Innenkegel c besitzt, in dem wiederum ein außen kegelig und innen zylindrisch geschlitzter Ring d gelagert ist. Mit dem Aufschrauben der Überwurfmutter b auf den Grundkörper e wird das in diesen lose eingeführte (Degen-) Rohr f gegen die Stirnfläche g mittels des Dichtungsringes h abgedichtet. Die zwischen den Dichtungsring )t und den Spannkegel d eingeschaltete Unterlegscheibe i verbürgt einerseits die Möglichkeit der freien Verdrehung zwischen den Körpern d und h und verhütet außerdem das Einquetschen der Gummidichtung in den durchgehenden Schlitz des Spannkegels d. Nach Herstellung der Abdichtung durch Verformung des Guihmiringes lt legt sich die Unterlegscheibe- i gegen die Stirnfläche des Grundkörpers e an, so däß nunmehr der Spannkegel d in den Innenkegel c eingepreßt und damit auf dem Rohr f festgezogen wird und dieses festhält.The union nut b, equipped with a corresponding internal thread, is screwed onto the external thread a of the base body e. When the union nut b is screwed onto the base body e, the (epee) tube f loosely inserted therein is sealed against the end face g by means of the sealing ring h. The washer i inserted between the sealing ring) t and the clamping cone d guarantees on the one hand the possibility of free rotation between the bodies d and h and also prevents the rubber seal from being squeezed into the continuous slot of the clamping cone d. After the seal has been made by deforming the guiding ring lt , the washer rests against the end face of the base body e, so that the clamping cone d is now pressed into the inner cone c and is thus tightened on the pipe f and holds it in place.

Mittels dieses Rohreinbaustücks ist es möglich, in axialer Richtung spannungsfreie Rohrleitungen zu verlegen. Durch Wärmeunterschiede oder durch einseitige Drücke auftretende Spannungen in den Rohrleitungen sind auslösbar, ohne die in Frage kommende Rohrleitung trennen zu müssen. Gleichzeitig ist damit das bequeme Auswechseln von Armaturen o. dgl. möglich, die in die Rohrleitung eingebaut oder einzubauen sind, und zwar selbst dann, wenn die auszuwechselnden Teile unterschiedliche Baulängen haben, ohne dazu die in Frage kommende Rohrleitung trennen oder in axialer Richtung verzerren zu müssen.By means of this pipe chock it is possible in the axial direction Laying stress-free pipelines. Due to differences in heat or one-sided Pressures occurring tensions in the pipelines can be triggered without the question having to disconnect the incoming pipeline. At the same time, it is easy to change of fittings or the like. Possible that are built into the pipeline or to be built into it are, even if the parts to be replaced have different overall lengths without disconnecting the pipeline in question or in the axial direction having to distort.
