Convenient-to-repair constituent part of municipal tap water pipeline joint

Abstract

The invention relates to the technical field of municipal facilities, in particular to a convenient-to-repair constituent part of a municipal tap water pipeline joint. The convenient-to-repair constituent part comprises two mounting pipes, a water-stop mechanism, a connecting mechanism and a fixing mechanism. The water-stop mechanism is fixedly arranged on the two mounting pipes to stop water whena pipeline is repaired, and the water-stop mechanism comprises two sealing shells, two valves and two groups of lifting assemblies; the connecting mechanism is arranged between the two mounting pipesto connect the two mounting pipes, and the connecting mechanism comprises a connecting pipe and a plurality of groups of inserting assemblies; and the fixing mechanism is arranged on the outer wallsof the connecting pipe and the two mounting pipes in a sleeving mode to fix the connecting pipe and the two mounting pipes, and the fixing mechanism comprises two groups of closing and compacting assemblies and two groups of positioning assemblies. According to the convenient-to-repair constituent part of the municipal tap water pipeline joint and a using method, a water valve main switch does notneed to be closed when a broken or blocked tap water pipeline is repaired, water resource waste is avoided, meanwhile, the joint is convenient to rapidly install and replace, and the sealing effect of the joint is good.

Description

technical field [0001] The invention relates to the technical field of municipal facilities, in particular to a component of a municipal tap water pipe joint that is easy to repair. Background technique [0002] my country's patent application number: CN201310047214.X; publication date: 2013.05.22 discloses a detachable pipe connector. It includes a connector base and two pressure rings; the connector base is a hollow tube, the middle of the outer surface of the connector base is a claw positioning groove, and the two sides of the claw positioning groove are symmetrically distributed from the inside to the outside. A force ring, at least one outer protrusion, and a ring at the end, the inner wall of the connector base is a cylinder; the outer surface of the pressure ring is provided with a pressure ring bearing groove, and one end of the inner wall has a The load-bearing ring has grooves with equal diameters on the surface, and the remaining part of the inner wall outside t...

AI Technical Summary

Problems solved by technology

[0005] 1. When repairing old or blocked water pipes, it is necessary to turn off the main switch of the water valve before repairing, which is very inconvenient and affects the production and life of residents

[0006] 2. Secondly, when repairing old or blocked tap water pipes, the water flowing in the pipe cannot be closed through the joint, but the main switch of the water valve needs to be turned off, which will cause waste of water resources and is not conducive to resource conservation

[0007] 3. When replacing and installing the joint, it is very inconvenient, which wastes workers' time and reduces work efficiency

[0008] 4. There is no specific design of the sealing structure between the joint and the pipeline, so the sealing effect of the joint needs to be improved
