Problems solved by technology

The main disadvantages of the existing sewage and exhaust pipe joints are as follows: one is that the outer wall of the pipe and the inner wall of the joint are bonded with glue. Sealing function; the second is that the joints of the joints are all thin-walled flat openings, which are only suitable for sealing with glue, and are not conducive to the insertion of pipes (especially the radial three-way and four-way joints); the third is the corner of the inner hole of the joint It is a straight line transition, resulting in small channels, large resistance, and slow flow rate; fourth, there is no reinforcement on the outer wall of the joint, and the mechanical strength is poor; fifth, the current large-caliber joints are generally welded and formed by metal materials, which is troublesome to process

Embodiment Construction

[0010] The invention discloses a sewage discharge and exhaust pipe joint. As shown in FIG. 1, a joint body 1 made of plastic is connected with an interface 2, and the interface can be multiple, such as two, three, four, etc. Its main technical feature is that the inner wall of the interface 2 is formed with a sealing groove 3, and a sealing ring 4 is installed in the sealing groove 3, and the sealing ring is in contact with the outer wall of the pipe, so as to overcome the shortcomings of the prior art glued and bonded and easy to separate , the sealing ring seal is also called flexible seal, such as rubber sealing ring, etc., the sealing performance is very reliable, when the pipe displacement changes, such as thermal expansion and cold contraction elongation or shortening, and deviation from the installation center line, it can be completely obtained by itself adjust. There is a flaring 8 on the interface, and the sealing groove is made in the flaring. The flaring is also ca...

Abstract

A discharge pipe joint has plastic made jointing body with interface, features in the seal groove with sealing ring loaded inside the inner wall of the interface, with the sealing ring contacting with the outer wall of the pipe. With is soft connection, it can regulate automatically, keeping constant sealing with reliable performance.

Description

technical field [0001] The invention relates to a pipe joint for sewage discharge and waste gas discharge, which belongs to infrastructure fittings. Background technique [0002] In urban construction, industrial and mining enterprise infrastructure, and rural residential construction, it is necessary to install sewage pipes, and some also need to install exhaust pipes (exhaust gas). must be connected with pipe joints. There are not only many types of pipe joints, such as two-way, three-way, four-way, and elbows. Moreover, the materials used are also different, and the commonly used ones are metal pipes, plastic pipes and cement pipes. The main disadvantages of the existing sewage and exhaust pipe joints are as follows: one is that the outer wall of the pipe and the inner wall of the joint are bonded with glue. Sealing function; the second is that the joints of the joints are all thin-walled flat openings, which are only suitable for sealing with g...
