A pvc pipe tail head device

Abstract

The invention provides a PVC pipe tail head device, including a pipe body and a tail end head, the tail end head is installed at the tail of the pipe body, and the tail end head includes a pressure dividing ring outside the pipe, an annular slot, and a sealing ring pad The inner wall of the pressure dividing ring outside the pipe is socketed with the outer surface of the pipe body, and the surface of the pressure dividing ring outside the pipe is inserted into the inner wall of the annular slot, which relates to the field of PVC pipes. The plugging structure designed by the PVC pipe tail head device can act on the inside and outside of the pipeline at the same time, and the impact of water flow can be used to enhance the sealing effect and the tightness of the connection. The multi-stage partial pressure weakens the impact of the structure and prolongs the service life. The structure can be quickly disassembled in a simple way, which effectively solves the problem that the general head needs to bear a large impact force when it is used, the force-bearing part has poor ability to disperse pressure, and is prone to leakage. The damage has a great impact on the pipeline, and it is inconvenient to repackage.

Description

technical field [0001] The invention relates to the technical field of PVC pipes, in particular to a head sealing device at the end of a PVC pipe. Background technique [0002] During the process of processing PVC pipes, both ends will be processed into a through shape, which is convenient for the pipes to connect with other pipes through the connecting device, and also facilitates the smooth water delivery of the pipes. Some pipes in the pipes are used as main pipes, which can be used in Its surface is connected with several branch pipes to transport water in different directions. At this time, the main pipe needs to be fixed with a head device for sealing at the end. At present, the commonly used head device is mainly a pipe with an open end and the same PVC material. Seal it with the main pipeline. This pipeline needs to withstand the impact of water flow during use. The end of the pipeline is always under impact pressure when it is in use. Therefore, the head of the pipe...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a PVC pipe tail head device, which solves the problem that the general head needs to bear a large impact force when it is used, and the ability to disperse the pressure at the stressed part is poor, and it is prone to accidents. In the case of leakage, and the damage of the head has a great impact on the pipeline, it is inconvenient to re-package the problem
