Socket and spigot type plastic pipe fusion welding device for conveying media through pressure

Abstract

The utility model relates to a socket-type plastic pipe welding device for pressure conveying medium. The whole device is arranged in the order of extruder, hot melt material storage barrel, feeding pipe, mold frame and support. There are upper mold and lower mold in the mold base, and a sealing plate is provided on one side of the upper mold and lower mold. , the inner side of the sealing plate is fixed with a mold core, the mold core moving cylinder fixed on one side of the mold base is connected with the sealing plate, the upper mold moving cylinder fixed on the mold base is connected with the upper mold, and the lower mold fixed under the mold base moves The cylinder is connected with the lower mold; when the socket tube is connected with the socket head, the defects of uneven connection strength of the electric heating belt and easy deformation and cracking of the pipe are overcome. The hot-melt connection between the socket pipe and the generated socket plug is firm, and the socket-type plastic pipe formed is suitable for operation in various environments. The relative cost of the project is low, and at the same time, the labor intensity of the operators is reduced, and the project progress is improved.

Description

technical field [0001] The invention relates to a socket-type plastic pipe welding device for a pressure conveying medium, which relates to the technical field of plastic pipe socket connection pipe fittings and is used for buried drainage pipes. Background technique [0002] In existing drainage projects, underground drainage pipes are buried, and plastic pipes are used as buried pipes. The connection methods: electric melting belt connection, clamp connection, heat shrink connection, flange connection, etc., are generally connected manually , Some connection methods have better strength, but the connection is difficult and the process is complicated. There are also some connection methods that are not suitable for working with water, especially the human factor of heating with a flame gun is very large, resulting in uneven connection strength between the socket-type plastic pipe and the socket sleeve, and the socket-type plastic pipe is affected by uneven gravity during se...

[0002] In existing drainage projects, underground drainage pipes are buried, and plastic pipes are used as buried pipes. The connection methods: electric melting belt connection, clamp connection, heat shrink connection, flange connection, etc., are generally connected manually , some connection methods have better strength, but the connection is difficult and the process is complicated

There are also some connection methods that are not suitable for working with water, especially the human factor of heating with a flame gun is very large, resulting in uneven connection strength between the socket-type plastic pipe and the socket sleeve, and the socket-type plastic pipe is affected by uneven gravity during settlement , it is easy to cause deformation and cracking between the socket-type plastic pipe and the connecting part of the socket, and the project has to be reworked, especially the socket-type plastic pipe with pressure conveying and increased flow is used as the underground drainage pipe, which is more prone to water leakage

In this way, both engineering materials and manpower are wasted, and the construction period is extended.
