Quick connection joint for plastic pipeline

Abstract

The invention provides a quick connection joint for plastic pipeline, relating to a connection structure of the plastic pipeline. The connection joint is made of a hard material, wherein a connection head (1) is a section from one external end to the middle part of the connection joint; a round-about groove (5) is arranged on the outer edge face of the connection head; an opening part stopping ring (2) is arranged on an inner wall (4) at one end inside an end face (6) at one end of the connection joint; clamps which are clamped with the external face of a rubber pipe (8) and are circularly distributed are arranged on the inner wall at one end; and a section from an inner face at the other end to the middle part of the connection joint is a horn opening (9) with a large external part and a small internal part at the other end. The quick connection joint provided by the invention is locked at an end head of the plastic pipeline through a mechanical effect, and forms a tight quick connection structure through the annular-distributed clamps. The quick connection joint ensures the good sealing property due to the specific structural design, so as to achieve rapid, efficient and convenient mounting, dismounting and maintenance. Therefore, the phenomena of releasing, breaking, and water and gas leakage of the pipeline, caused by the conventional connection manner, can be effectively overcome.

Description

【Technical Field】 [0001] The invention relates to a plastic pipe connection structure, in particular to a quick connection joint of a plastic pipe. 【Background technique】 [0002] At present, the well-known connection methods of large-diameter plastic pipes are nothing more than: the straight or R port of the PVC pipe is inserted into the connection method, and the other is the connection method of bonding flat flanges at both ends of the pipe, PE, PP- R pipe hot-melt connection method. None of the above methods can achieve fast and efficient installation, disassembly and maintenance. In particular, it cannot be widely used in mines and coal mines. Because the environment in the mine or coal mine is very harsh, the pipeline cannot be effectively fixed, and the pressure of the pipeline is very unstable, the working conditions are wet, and the space is narrow. After connection, the pipe joints are more likely to fall off, break, leak water and air, which adds inconvenience and ma...

Problems solved by technology

Above-mentioned method all can't accomplish fast, efficient installation, disassembly and maintenance

In particular, it cannot be widely used in mines and underground coal mines. Because the environment in mines or underground coal mines is very harsh, the pipeline cannot be effectively fixed, and the pressure of the pipeline is very unstable, the working conditions are humid, and the space is narrow. After connection, the pipe joints are more likely to fall off, break, and leak water and air, which adds inconvenience and major safety hazards to the underground production of mines and coal mines
