Description

Technical field

The technical solution relates to a plug-in pipe connection for connecting pipes of polyethylene or other plastics for the transport of water, gas and other media. Pipe connection is simple, fast and allows a high degree of joint sealing.

Background Art

Plumbing, pipeline or other polyethylene or other plastic pipelines for conveying liquid and gaseous media are commonly joined by butt welding or various types of couplings. The most common type of couplings are threaded couplings and seals tightened by thread. The drawback of threaded and gasketed joints is the high effort to make this joint when threading and the need for qualified assembly requiring precise threading. The disadvantage of butt joints is their high workload and the annulus ring, which results in a reduced cross-section of the welded pipe. Welded pipes cannot be easily dismantled.

The essence of the technical solution

The above drawbacks are largely eliminated by the plug-in pipe connection according to the present invention, which consists of a plug-in pipe connection in which a sealing O-ring and a clamping split ring are mounted on the inner wall, the plug-in pipe connection chamber being fitted with a cuff on the entry side.

The plug-in pipe connection according to the invention is designed as a self-locking and automatic sealing joint. The principle of a plug-in pipe connection is a seal using an O-ring located in the joint chamber. The joint is resistant to pressure axial forces based on the internal shape of the chamber and the split clamping ring between the tube and the inner wall of the chamber. The inner surface of the split clamping ring and the inner wall of the body of the plug-in pipe joint are of conical shape with each other and the clamping split ring is radially scored. The chamber of the plug-in pipe joint is closed by a rubber sleeve to prevent dirt from entering the joint. The connection is assembled by simply inserting the pipe into the chamber of the plug-in pipe connection. The smooth end of the pipe is chamfered for easy insertion of the pipe into the chamber of the plug-in pipe connection. The pipe is pushed over the split clamping ring and the O-ring seal to the back of the plug-in pipe connection chamber.

List of drawings in the drawing

The technical solution is explained in more detail by means of the drawings, in which Fig. 1 shows a section of a plug-in pipe connection without a plug-in tube and Fig. 2 a section of a plug-in pipe connection with a plugged-in tube.
