Description

Double-sealing groove type pipe fitting

Technical Field

The utility model relates to the field of pipeline connection, in particular to a double-seal groove type pipe fitting.

Background

A conduit is a device for transporting a gas, a liquid or a fluid with solid particles. In the use of pipes, it is often necessary to connect two pipes to change the direction of the pipes or to extend the conveying distance of the pipes. There are different connection methods depending on the material of the tube used. The common steel pipes are connected by screw threads, flanges, welding, socket connection, pipeline bonding connection and the like. And for plastic pipes, a hot melt splicing mode is often adopted. The Chinese patent discloses a spiral covered leakage-proof composite pipe (issued publication No. CN 215410847U), which solves the problems that when in hot-melting connection, the joint of two pipelines needs to be subjected to hot-melting treatment, then when the pipelines are in a molten state, the pipelines are jointed, and the connection is completed after the pipelines are cooled. Because the water pipe and the pipe joint are directly injection-molded, the body of the pipe is firm and not easy to damage, the joint of the pipe and the pipe joint is the position which is most easy to damage, when the joint of the pipe is bent by external force, the joint of the pipe can bear great bending force, and the joint of the pipe is easy to be in virtual joint, thereby causing leakage, and the joint of the pipe is directly contacted with the outside, so that the problem of damage is easy to cause. However, the spiral covering type leakage-proof composite pipe is heated by the inside of the water pipe and the outside of the pipe joint, then the pipe joint is inserted into the water pipe, the water pipe and the pipe joint are waited for cooling, the connection between the water pipe and the pipe joint is completed, the connection sealing effect between the water pipe and the pipe joint is poor, and the problem of reduced sealing performance after long-term use exists.

Accordingly, a double seal groove type pipe fitting is provided by those skilled in the art to solve the above-mentioned problems in the background art.
