Abstract

Device for the medium-tight connection of a pipe, with a socket part, of which at least one end serves for the insertion of the pipe and, at its end, exhibits a flange with a conical abutment surface for a sealing ring with an essentially circular cross-sectional surface area, and is provided with a peripheral reinforcement integrated into its elastomeric material, the socket part being assigned an oppositely arranged bracing part in the form of a flange, and the reinforcement of the sealing ring, which can be compressed around a pipe pushed into the socket part, comprising pipe parts which are assembled in the form of a ring and can be telescopically pushed together to a restricted extent.

Description

The invention relates to a device for media-tight Connection of a pipe with a socket part, of which min at least one end is used to insert the tube and on a flange with a conical contact surface at its end che for a sealing ring with essentially circular of the cross-sectional area and with one in elastomeric material with integrated all-round reinforcement is provided, with the sleeve part a counter Clamping part is assigned in the form of a flange.

In this device known from DE-OS 19 59 666 is achieved by the effective application of tendons of the seal ring between the sleeve part and the clamping part together pressed and against a pipe end arranged in the socket part pressed. The sealing ring is with one in it elastomeric material integrated, all-round reinforcement Mistake. The reinforcement consists of a coil spring. The disadvantage of the known device is that agile construction of the sealing ring. In addition, the be Known device not suitable for pipes with under different diameters in the sleeve part to be media-tight shut down. You had to go under for pipes with each other different pipe diameters always have this ratio Have the adapted device ready.

The invention has for its object an inexpensive te, easy to use device in the preamble to develop the type of claim 1, the weitge regardless of the varying pipe diameter for a good media-tight connection of the pipe to the socket Feil cares.

This object is achieved in that the Reinforcement of one inserted in the sleeve part Pipe compressible sealing ring made of a ring composite pipe parts, which is telescopic can be pushed together to a limited extent. With these telescopic limited collapsible pipe parts becomes easier Created a reinforcement for the sealing ring, which has the required strength and under different pipe diameters can be adjusted by the activation of the tendons.

The reinforcement of the sealing ring can consist of eight ring-shaped mig composite and telescopically collapsible ren pipe parts exist. This is easy the armouring is made up of eight pipe parts that form the tele Reliable telescopic sliding of the pipe parts enables.

The telescopically collapsible pipe parts can Ab each tapered in diameter at one end cuts for telescopic insertion into the others Have ends of the pipe parts. As a result, in simple cher way the pipe parts each with their diameter tapered end sections into the other ends of the tube parts are telescopically moved into each other, so that the diameter of the sealing ring of the respective  Adapts to size.

The telescopically collapsible pipe parts can are made of metal. This assigns them telescopically collectible pipe parts have the required strength on.

The telescopically collapsible and made of metal standing pipe parts can be elastic and / or limited be permanently deformable. This will make the sealing ring adapted to the required diameter.

In the drawing, the invention is in one embodiment example shown, namely shows

Fig. 1 is a device for media-tight con nection of a pipe having a socket part in longitudinal section;

Fig. 2 shows the same device for media-tight connection of a pipe with a sleeve, but the pipe has a smaller outer diameter, in longitudinal section, and

Fig. 3 shows a sealing ring in longitudinal section.

The device shown in the drawing is used for media-tight connection of a tube 10 with a sleeve part 11 , of which at least one end is used to insert the tube 10 . The sleeve part 11 is provided at its end with a flange 12 with a conical contact surface 13 . The conical contact surface is provided for a sealing ring 14 with an essentially circular cross-sectional area.

The sealing ring 14 consists of an elastomeric material and has an integrated circumferential reinforcement 15 . The sleeve part 11 is assigned a counterpart clamping part 16 , which has the shape of a flange 17 . The flange 17 of the clamping part 16 is to be tightened with screws, not shown, against the flange 12 of the sleeve part 11 , so that the sealing ring 14 can be reliably pressed against the conical contact surface 13 of the sleeve 11 by the system with its elastomeric material, against the flange 17 of the Clamping part 16 and the outer surface 18 of the tube 10 is pressed. The reinforcement 15 of the sealing ring 14 retains the sentlichen we its previous shape, and only made of elastomeric material sealing ring 14 receives a conditional by the pressing contact surface. As can be seen in particular from FIG. 3 in particular, the reinforcement 15 of the tube 10 inserted around the sleeve part 11 to be compressible sealing ring 14 consists of eight ring-shaped tubular parts 19 which can be telescopically pushed together. The telescopically collapsible pipe parts 19 each have at one end tapered sections 20 for telescoping term insertion into the other ends 21 of the pipe parts 19 . The telescopically collapsible pipe parts 19 are made of metal and thus have the required strength. The metal pipe parts are limited elastic and / or permanently deformable to ensure the necessary compression of the sealing ring 14 . With the device according to the Invention, a media-tight connection of the tube 10 is thus ensured, which is largely independent of the varying tube diameter.

As already mentioned, the embodiment shown is only an example of realizing the invention and is not limited to this. Rather, various other designs and modifications are possible. The reinforcement 15 could also consist of more or less than eight pipe parts 19 . In addition, it is also possible to ensure that the telescopic sliding into one another in that in each case one tubular part 19 has a smaller outer diameter than the inner diameter of the adjacent tubular part.
