"Device for connecting a plastic pipe with another pipe "

The innovation relates to a device for connecting a Xunstatoffrohros with another jäohr, in which the plastic tube is inserted into a socket housing and onto it Tube an O-ring is pushed on, which is pressed sealingly by means of a screw connection on the Nuffengehäuae and a protective ring inserted in between

Such a device is known in which the plastic pipe is pushed into the socket housing and there has a guide in its end part. An O-ring is pushed against a collar in the socket housing for sealing,

to which a smooth sclmler protective ring is attached. One on the union nut screwed on the socket housing pulls you in slotted clamping ring against the protective ring, whereby the seal is pressed and the clamping ring is tensioned. After this If the union nut is tightened sufficiently, the connection is firmly and adequately sealed.

The task of the innovation is to make such a device more cost-effective with sufficient functional reliability.

Therefore, to achieve this object of the innovation is a device of the initially mentioned type is proposed which are characterized by a 1 t screwed into the socket housing with a molded threaded neck with a stuffing box inside.! Ying sawtooth profiling.

In this device, the threaded connector on the stuffing box screw pulls itself into the interior of the socket housing and presses the O-ring seal against a sealing surface on the socket housing and axially against the plastic pipe via the protective ring in between. As a result of the sawtooth profile inside the stuffing box screw, sufficient clamping of the plastic pipe is achieved with a corresponding guide in the connecting device. Compared to known devices, according to the innovation, the slotted clamping ring is omitted, the cost of which has a not insignificant effect on the overall costs of the device.

The innovation is explained in the following on the basis of an illustrated exemplary embodiment. It shows

Fig. 1 in a sectional view of the innovation according to the invention Connecting device

and

2-5, in an assembly arrangement, the partially sectioned individual parts of the device according to FIG. 1.

A plastic pipe 5 is inserted into the socket housing 4 and is guided by the part k2 of the housing. On the other side, the socket housing k has a connecting piece kl for the other pipe, which can be a plastic or a metal pipe.

After the plastic pipe 5 has been pushed into the socket housing k , an O-ring 3 is pushed onto the pipe 5 for a sealing connection, followed by a narrow, smooth protective ring

The pressing takes place via a stuffing box screw 1 with an ajgeformten threaded connector 12. By means of the external thread 14 on the threaded connector 12, the stuffing box screw 1 can be screwed into the internal thread 43 of the socket housing h. At the

Screwing in, the end face of the threaded connector 12 presses against the protective ring 2, which in turn zussiHfflsnprsSt the O-ring 3. df "is supported on the sndsren side on the · sealing surface k2 of the socket housing h . In its inner bore, the union nut 1 is provided with a saw-tooth-like profile 13, which counteracts the unintentional pulling out of the plastic pipe 5 from the connecting device a key cake »kk perish.
