Pipe connection and assembly body

Abstract

The invention relates to a pipe connection and assembly body. The pipe connection and assembly body comprises a pipe joint, a pressurized body and a fixture, wherein the pipe joint comprises a diameter expansion opening formed in one end of which the inside diameter is gradually expanded, the pressurized body comprises a pressurized ring which is opposite to the diameter expansion opening and an elastic ring which is combined with one side of the pressurized ring and is inserted into the diameter expansion opening, and the pressurized ring can be fastened by the fixture so as to pressurize theelastic ring, so that the air tightness is increased. The pipe connection and assembly body has the advantages that the waterproof sealing performance of hinges and cushions of connecting pieces canbe stably guaranteed, the construction is convenient, the waterproof sealing performance is excellent, the fastening is difficult to loose, and the construction cost can be greatly reduced.

Description

technical field [0001] The present invention relates to a pipe connection assembly, in particular to a pipe connection assembly that connects pipes on pipes such as sewage and waste water pipes of public facilities or residences and underground horizontal main pipes, and is connected by fastening. . Background technique [0002] The connecting piece between the pipes used in the prior art is usually in the shape of a flanged pipe, which can generate a certain pressure inside the pipe to prevent the pipe from detaching. This kind of pipe connecting piece is usually equipped with waterproof Sealed cushions, and the flanges are tightly connected with multiple bolt hinges. [0003] However, when fastening the pipe connectors, multiple bolts need to be tightened separately. In order to make the pipe connectors evenly close to each component, higher requirements are placed on the proficiency and strength of the staff. When it is necessary to repair or replace the pipe parts, it ...

Problems solved by technology

[0003] However, when fastening the pipe connectors, multiple bolts need to be tightened separately. In order to make the pipe connectors evenly close to each component, higher requirements are placed on the proficiency and strength of the staff. When it is necessary to repair or replace the pipe parts, it is necessary to disassemble the pipe connectors one by one and reassemble them with the pipe, which will consume a lot of manpower and time; moreover, the cushion used for waterproof sealing can only be fastened on the outside of the pipe , so it is difficult to maintain its waterproof sealing performance, and when the pipe is inserted into other pipes, it is difficult to install the pipe and the cushion inside the pipe connector, so there are many problems

In addition, when using a clamp fixed with multiple bolts as a fastening member to connect the pipes, it is necessary to disassemble the fastening part of the connecting piece and insert a cushion that can be added to the outer circumference of the pipe to be connected during maintenance. The process of pressing the ring, and after a series of processes, it is necessary to fasten the fixture with multiple bolts, so it is more cumbersome
