A reverse pressure connector for non-metallic pipelines

Abstract

The invention relates to the technical field of connection equipment for non-metallic pipes, and discloses a reverse pressure connector for non-metallic pipes, including non-metallic pipes, an inner ring mechanism and an outer ring mechanism. The inner wall is clamped with an inner ring mechanism, the outer surface of one end of the non-metallic pipe is fixedly sleeved with an outer ring mechanism, and the non-metallic pipe and the outer ring mechanism are clamped by a locking screw with a round head at one end. The reverse pressure connector for non-metallic pipes can form a stable support ring on the inner wall of the non-metallic pipes to prop them apart when connecting two sets of non-metallic pipes through the setting of the inner ring mechanism and the outer ring mechanism. This makes the sealing of the outer ring mechanism better when installing and clamping non-metallic pipes, and will not cause the fluid in it to leak due to irregular deformation due to the extrusion of the pipe wall, thereby effectively improving the performance of the connector. Safety and stability when connecting two sets of non-metallic pipes.

Description

technical field [0001] The invention relates to the technical field of connection equipment for non-metallic pipelines, in particular to a reverse pressure connector for non-metallic pipelines. Background technique [0002] At present, in order to control the production quality of pipelines and the convenience of transportation, all large-diameter pipelines have standard lengths when they leave the factory. Therefore, when using pipelines for long-distance transportation, the same type of The pipes are snapped together to achieve the proper distance length. [0003] However, the existing pipe connections are usually realized by clamping clamps or pipe clamps. This connection method has a better connection effect when connecting metal pipes, but when connecting non-metallic pipes, due to non-metallic pipes It has a certain degree of elasticity. In the process of connecting and locking with clamping clamps or pipe clamps, due to extrusion, the pipe wall of the pipe will be de...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a reverse pressure connector for non-metallic pipelines, which has the advantages of good sealing performance, high stability and firmness, and good safety when connecting two sets of pipelines, and solves the existing problems The pipe connection is usually achieved by clamping clamps or pipe clamps. This connection method has a better connection effect when connecting metal pipes, but when connecting non-metallic pipes, due to the non-metallic pipes have certain Elasticity, in the process of connecting and locking with clamping clamps or pipe clamps, due to extrusion, the pipe wall of the pipe will be deformed irregularly due to uneven force, and then appear when connecting non-metallic pipes Subtle gaps, poor sealing effect and stability for pipeline connections, leakage under the action of fluid pressure, low stability and reliability
