Clamp connectors for pressure-tight and detachable connections of pipes made of flexible material, especially for plastic pipes

The innovation relates to a clamp connector for pipes from one compliant material, especially for plastic pipes or the like. with üa straight, angular or T-shaped with a flow channel provided base body, one in a connection end of the base body used support body for a pipe end, a put on the pipe end, slotted clamping ring equipped with a cone and a screwing body cooperating with the cone of the clamping ring.

A clamp connector of this type is known in which the base body for example T-shaped itt and the connection ends that Base body are provided with an external thread. The one in a connection end The support body inserted in the base body has a hollow pin protruding from the connection end and pushed onto a pipe end that is enclosed by a slotted clamping ring. Means a union nut, which is on the connection end of the Grurtdkkörpers is screwed, the clamping ring is pressed onto the pipe end, for the the Hüfilzapfen of the support body is the abutment for this clamp connection bilGet.

When screwing on the union nut and when pressing on the clamping ring On the pipe end, the pipe to be connected to the base body is subjected to a torsional load due to friction between the union nut and the clamping ring exposed, under which the pipe rotates about its longitudinal axis.

This on the one hand makes the assembly more difficult and on the other hand the With the pipe connected to the base body, an additional torsional stress is added.

The innovation is based on the task of a clamp connector for pipes or the like. of the type mentioned at the outset in such a way as to allow production the clamp connection, the pipe to be fixed or the like. of torsional loads is kept free.

According to the innovation, this object is achieved in that the with the Clamping ring cooperating Verschraubungskorper one on the connection end of the base body is assigned rotatably mounted counter nut and the connecting end of the base body is an abutment ring for the counter nut having.

When screwing on or screwing in the lock nut, the one with the End of the tube clipped clamping ring cooperating screwing body, which are held with a pipe wrench or an appropriate key can, only in the direction of the longitudinal axis of the pipe, i.e. translationally moved so that the pipe to be fixed no torsional forces given up will.

An embodiment of the innovation is shown in the drawing and is described below.

The clamp connector for pipes 1 shown in the drawing has a T-shaped base body 2, which with passage channels 3 and 4 is equipped.

A support body 6 is partially inserted into the connection ends 5, which is equipped with a collar 7, of which a hollow pin 8 is to the side facing away from the base body 2 extends. One end of the pipe 1, e.g. a plastic pipe, is pushed onto this hollow pin, onto which a slotted clamping ring 9, which is equipped with a cone 10, has previously been placed. A conical one works with this cone Clamping surface 11 of a screw connection body 12 together, which means a lock nut 13 is transported into the clamping position, which is shown in the drawing on the right side.

In the embodiment shown in the drawing, the lock nut is 13 designed as a union nut, which is supported with an annular end plate 14 on an abutment ring 15 and on the connection end 5 of the base body 2 is rotatably mounted. The union nut is screwed onto an external thread 16 of the screw connection body 12. The frictional forces that occur here and act on the screw connection body are relatively small and can be picked up by the fitter who grips the screw connection body 12 with pliers. Of the Screw body 12 is then in its clamping position only by an in brought with respect to the tube 1 axial movement.

In a modification of the construction shown, it is also conceivable that the counter nut 13 in an internal thread of the screw connection body 12 is screwed in.

In the illustrated embodiment, the abutment ring 15 screwed onto an external thread 17 of the connection end 5. The abutment ring 15 is equipped with an internal left-hand thread so that the abutment ring opens when the counter nut is screwed on or in or can not loosen in the screw connection body 12.

Furthermore, a ring would also be sprinkled into a groove in the base body as an abutment ring Circlip conceivable.

The abutment ring can be used when using a straight body • Can also be designed in one piece with the base body.
