Pipe capable of being conveniently and hermetically connected by adopting spigot and socket modes

Abstract

The invention discloses a pipe capable of being conveniently and hermetically connected by adopting spigot and socket modes, and relates to the technical field of pipes. The pipe comprises a pipe body, wherein one end of the pipe body is arranged to be the socket end after flaring, the other end of the pipe body is arranged to be the spigot end which can be in insertion connection with the socketend, the socket end is sequentially provided with a first socket and a second socket from inside to outside, the spigot end is sequentially provided with a first inserting portion and a second inserting portion from inside to outside, the first socket is in insertion connection with the first inserting portion, and the second socket is insertion connection with the second inserting portion. According to the pipe, due to the fact that the socket end and the spigot end of the corresponding ends of the designed two pipe bodies are inserted and matched in a staggered mode, and five layers of connecting parts which are arranged in a staggered mode are arranged in total, so that the compression resistance of the connecting parts is improved, the stability and reliability of connection are improved, and the problem that an existing pipe cannot bear large pressure strength after being connected by adopting an inserting mode is solved.

Description

technical field [0001] The invention belongs to the technical field of pipes, and in particular relates to a pipe which is convenient to be closely fitted and connected in a socket-and-socket manner. Background technique [0002] The pipes used in the fields of urban drainage, industrial and mining ventilation, etc. are usually connected by several pipes sockets into one body due to the limitation of road transportation and construction site. With the advancement of plastic pipe technology, plastic pipes are more and more widely used in the above fields. At present, the sealing connection methods of plastic pipes generally include sealing ring connection, flange connection or electric hot-melt connection. In the pipeline construction sites in the fields of urban drainage, industrial and mining ventilation, etc., the sealing connection methods of plastic pipes in the prior art are greatly restricted. For example, the sealing ring connection method is very laborious to constr...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a kind of pipe material that is convenient to be connected by socket and socket. Through the staggered insertion fit between the socket end and the socket end of the corresponding ends of the two pipe bodies, there are five layers in total. The connection part provided improves the compression resistance of the connection, improves the stability and reliability of the connection, and solves the problem that the existing plug-in method cannot bear a large pressure after the connection is completed.
