Description
Die Erfindung bezieht sich auf eine Klemmverbindung zwischen zwei vorzugsweise aus Kunststoff gefertigten Rohren, von denen eines mit einer mit einem Außengewinde ausgerüsteten Muffe versehen ist, in die das andere Rohr eingesteckt ist, wobei die Muffe einen konisch nach innen sich erstreckenden Öffnungsrand aufweist, an dem sich ein konisch sich verjüngender Dichtungsring abstützt, der mittels einer auf das Außengewinde der Muffe festgelegten Überwurfmutter auf das in die Muffe eingesteckte Rohr gepreßt wird.The invention relates to a clamp connection between two pipes, preferably made of plastic, one of which is provided with a sleeve equipped with an external thread, into which the other pipe is inserted, the sleeve having an opening edge extending conically inwards, on which a conically tapering sealing ring is supported, which is pressed onto the pipe inserted into the sleeve by means of a union nut fixed to the external thread of the sleeve.
Es ist eine Klemmverbindung dieser Art bekannt, bei der der aus Gummi oder Kunststoff gefertigte Dichtungsring ein separates Teil bildet, das sich mit einer ringförmigen Anlagefiäche an einer entsprechenden Stützfläche der Überwurfmutter anlegt, wenn diese auf das Außengewinde der Muffe geschraubt wird. Hierbei arbeitet der sich zum freien Öffnungsrand konisch verjüngende Dichtungsring mit einem Innenkonus der Muffe zusammen und wird auf das in die Muffe eingesteckte Rohr gepreßt.A clamp connection of this type is known in which the sealing ring made of rubber or plastic forms a separate part, which rests with an annular contact surface on a corresponding support surface of the union nut when the latter is screwed onto the external thread of the sleeve. In this case, the sealing ring, which tapers conically towards the free opening edge, works together with an internal cone of the sleeve and is pressed onto the pipe inserted into the sleeve.
Der Erfindung Iiegt die Aufgabe zugrunde, die Anzahl der Funktionsteile der eingangs genannten Klemmverbindung zu verringern und die Montage zu vereinfachen.The invention is based on the object of reducing the number of functional parts of the clamp connection mentioned above and simplifying assembly.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Dichtungsring mit der Überwurfmutter einstückig ist.This object is achieved according to the invention in that the sealing ring is integral with the union nut.
Bei der erfindungsgemäßen Klemmverbindung entfalten somit eine separate Fertigung, Lagerung und Montage des Dichtungsringes.The clamp connection according to the invention thus requires separate production, storage and assembly of the sealing ring.
Weitere Merkmale der Erfindung ergeben sich aus den Unteransprüchen.Further features of the invention emerge from the subclaims.
Ein Ausführungsbeispiel der erfindungsgemäßen Klemmverbindung ist in den Zeichnungen dargestellt und wird im folgenden beschrieben.An embodiment of the clamping connection according to the invention is shown in the drawings and is described below.
Es zeigen:Show it:
. Figur 1 die Funktionsteile der Klemmverbindung im Schnitt und in demontiertem Zustand und. Figure 1 the functional parts of the clamp connection in section and in dismantled state and
Figur 2 die fertigmontierte Klemmverbindung im Schnitt.Figure 2 shows the fully assembled clamp connection in section.
Das Rohr 1 weist eine Muffe 2 auf, die mit einem Außengewinde 3 versehen ist. Nach dem Aufstülpen einer Überwurfmutter 4 auf das zweite Rohr 5 wird das Rohr 5 in die Muffe 2 eingeführt und anschließend durch das Aufschrauben des Innengewindes 6 der Überwurfmutter 4 auf das Außengewinde 3 klemmend festgelegt.The pipe 1 has a socket 2 which is provided with an external thread 3. After slipping a union nut 4 onto the second pipe 5, the pipe 5 is inserted into the socket 2 and then clamped into place by screwing the internal thread 6 of the union nut 4 onto the external thread 3.
Zur Erzielung dieser Klemmverbindung ist die Muffe mit einem vom Öffnungsrand 7 ausgehenden Innenkonus 8 versehen, der mit einem Dichtungsring 9 zusammenwirkt, der zum freien Rand 10 sich konisch verjüngt mit der Überwurfmutter 4 einstückig ist.To achieve this clamping connection, the sleeve is provided with an inner cone 8 extending from the opening edge 7, which interacts with a sealing ring 9, which tapers conically towards the free edge 10 and is in one piece with the union nut 4.
Die Überwurfmutter 4 weist an der Einführseite für das in die Muffe 2 des Rohres 1 einsteckbare Rohr 5 einen im Durchmesser dem Außendurchmesser des Gewindeteils der Überwurfmutter 4 abgesetzten Stutzen 11 auf. Dieser Stutzen 11 ist an der Einführseite mit einem Konus 12 versehen. Der Konus 12 geht in einen zylindrischen, mit Innenrippen ausgestatteten Teil 13 über, an dem sich der Dichtungsring 9 anschließt. The union nut 4 has a socket 11 on the insertion side for the pipe 5 that can be inserted into the socket 2 of the pipe 1, which has a diameter that is the same as the outer diameter of the threaded part of the union nut 4. This socket 11 is provided with a cone 12 on the insertion side. The cone 12 merges into a cylindrical part 13 equipped with internal ribs, to which the sealing ring 9 is connected.
Die Überwurfmutter ist zur Erzielung einer guten Verformbarkeit des Dichtungsringes 9 aus einem gummielastischen Kunststoff gefertigt.The union nut is made of a rubber-elastic plastic to ensure good deformability of the sealing ring 9.
Die Montage des Rohres 5 ist auch in der Weise durchzuführen, daß zunächst die aus elastischem Material gefertigte Überwurfmutter auf das Außengewinde der Muffe geschraubt oder gesteckt wird und anschließend das Rohrende des Rohres .5 in dieThe assembly of the pipe 5 is also to be carried out in such a way that first the union nut made of elastic material is screwed or inserted onto the external thread of the socket and then the pipe end of the pipe .5 is inserted into the
