Abstract

The invention discloses a PE pipe, and relates to the technical field of the PE pipe. The PE pipe at least comprises a pipe body, a mounting hole which penetrates through the inner pipe wall and the outer pipe wall is formed in the pipe body, a dust collecting mechanism is arranged in the mounting hole, and the dust collecting mechanism comprises an embedded pipe and a lifting dust collector. Theinvention provides the PE pipe capable of collecting and clearing dust particles in the pipe and reducing the leakage risk of a pipe valve to solve the problem of leakage of the pipe valve caused by the fact that the dust particles in an existing natural gas pipe network easily scratch the inner wall of the pipe valve.

Description

technical field [0001] The invention relates to the technical field of PE pipe fittings, in particular to a PE pipe fitting capable of collecting dust particles in pipes. Background technique [0002] In the natural gas pipeline network, metal pipe valves are gradually being replaced by PE pipe valves (that is, polyethylene pipe valves). PE pipe valves have the advantages of light weight, corrosion resistance, long life, and easy installation and maintenance. However, because the PE pipe valve is made of plastic, it is not resistant to scratches. During the installation and operation of the natural gas pipeline network, it is inevitable that dust particles will enter the inner cavity of the pipe valve. If it is not cleaned in time, the inner wall of the pipe valve will be scratched. Especially for PE ball valves, if the outer wall of the valve core is scratched by dust particles, it is easy to cause leakage of the ball valve after a long time, and in more serious cases, it m...
