a pipe fitting

Abstract

The invention discloses a pipe fitting, which comprises a pipe fitting main body composed of more than one section of pipe body and more than one expansion joint. An expansion joint is installed between them, and the pipes on both sides are connected through the expansion joint. The total length of the entire pipe body is longer than the length of the embedded cavity, and the expansion joint of the entire pipe body is squeezed and buried in the embedded cavity. Inside and through the pre-embedded cavity to limit both sides, the extruded expansion connector protrudes outward and forms a support ring to contact and support the bottom surface of the pre-embedded cavity. The pipe fitting of the present invention has very good resistance to compression and shearing. Even if the pipe fitting is cut into two as a whole, it can slowly restore the deformation of the pipe fitting, reduce the water output, and further reduce the loss of water source.

Description

technical field

[0001] The invention relates to the field of pipelines, in particular to a pipe fitting. Background technique

[0002] In the prior art, pipe fittings are generally used for the long-distance transmission of gas and fluid, but the general pipe fittings are made of PVC plastic, and when they are buried in the ground or arranged on the ground for discharge, they often break. Some of the ruptures are caused by external environmental influences, and some are caused by external force cutting, but once such pipes are cut or ruptured, or a large amount of resource loss occurs, if it is a water pipe, a large amount of water will flow out, causing serious damage to water resources. Waste, and the pipeline is generally in direct contact with the bottom surface of the pipeline. Because of the rigid contact between the two, the compressive capacity is poor. Once there is some extrusion, the pipe fittings may rupture, and the compressive performance is poor. Contents of...
