Pipe joint structure

Abstract

The invention discloses a pipe joint structure, and relates to the technical field of pipeline engineering. The pipe joint structure is designed to solve the problems that an existing pipe joint structure is not reliable and the like. According to the pipe joint structure, positioning protruding rings are arranged on a first pipe end socket, positioning annular grooves are formed in a second pipe end socket, a pipe joint is comprehensively sealed through matching of the positioning protruding rings and the positioning annular grooves and through first sealing pieces between the adjacent positioning protruding rings, and the problem that leakage happens to the pipe joint can be effectively avoided; clamps are arranged outside the pipe end sockets, and hinged shafts of the clamps are fixed into joint fixing pieces so that the two pipe end sockets of the pipe joint can be effectively prevented from being disengaged and structure reliability and use safety of the pipe joint can be greatly improved; the first pipe end socket is matched with a clamping table of the corresponding joint fixing piece through a boss so that the first pipe end socket can be positioned, the second pipe end socket is connected with the corresponding joint fixing piece in a threaded mode, the installation method is more convenient, and production efficiency can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of pipeline engineering, in particular to a pipe joint structure. Background technique [0002] In the pipeline layout of pipeline engineering, because the length of the pipe fittings is too long, it will affect its rigidity. It is necessary to connect each section of pipe fittings through pipe joints. In addition, in practical applications, it is also necessary to connect two pipe fittings with different diameters. In the case of being together, in this case, a pipe joint is also required to connect two pipe fittings with different pipe diameters. [0003] The existing pipe joint structure is to connect the two pipe fittings through the threaded connection of the two pipe fittings outside the joint fixing part. This connection method has the following problems: [0004] (1) The joints of the two pipe fittings are poorly sealed and easily leak, which affects the entire pipe fitting project; [0005] (2) Si...

AI Technical Summary

Problems solved by technology

[0004] (1) The joints of the two pipe fittings are poorly sealed and easily leak, which affects the entire pipe fitting project;

[0005] (2) Since the pipe fittings and joint fixing parts are threaded, the connection is not reliable enough, and it is easy to loosen;

[0006] (3) The connection of pipe fittings is inconvenient, which affects production efficiency
