A pvc pipe for sewage treatment

Abstract

The invention provides a PVC pipeline for sewage treatment, which includes a pipeline group mechanism, a sewage branch pipe and an air-induction and drainage mechanism. The pipeline group mechanism includes a plurality of sewage pipe bodies, a connection ring, a first connection groove, a water inlet and a water outlet, and several One end of the sewage pipe body is provided with a second connecting groove, the first connecting groove is opened on the surface of the connecting ring, the cross-sectional view of the connecting ring is in the shape of an I, and the outer surface of the sewage pipe body is threaded with the inner top wall of the first connecting groove. Connection, involving the field of PVC pipes. The PVC pipe for sewage treatment uses a special structure to guide the water flow and air to carry out offside partial pressure, and weaken the high-pressure gas and high-pressure water flow through the offside partial pressure method, thus effectively solving the problem of general PVC sewage pipes in use. It is easy to be affected by the increase of air pressure caused by the encounter of sewage inside the pipeline, and the increase of water pressure in the pipeline caused by the collision of sewage.

Description

technical field [0001] The invention relates to the technical field of PVC pipes, in particular to a PVC pipe for sewage treatment. Background technique [0002] PVC pipes are a kind of pipes that are more convenient to install in sewage pipes. They are often used as urban underground sewage pipes. When PVC pipes are used, the underground sewage system is more complicated. After some pipes are connected, if a section of sewage The pipeline is discharging sewage, and the other section of the pipeline is also facing the situation of rapid sewage discharge, especially when the water potential at the rear is relatively fast, and the section of the pipeline that is being drained quickly rushes to the front, and when the sewage is approaching, there is a large amount of water in the middle. Air, the air is difficult to discharge in a narrow space and will generate a strong air pressure. This air pressure is very likely to burst the pipe, and when the two waters meet, the water pre...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a PVC pipe for sewage treatment, which solves the problem that when the general PVC sewage pipe is in use, it is easily affected by the increase of air pressure caused by the encounter of sewage inside the pipe, and the impact of sewage encountering the inside of the pipe. The impact of increased water pressure can easily cause pipe bursts for a long time
