Elbow connector

Abstract

The invention provides an elbow connecting piece. The mode that a first connecting piece and a second connecting piece are connected for use is adopted in the elbow connecting piece. The first connecting piece is provided with a mounting plate which is provided with a joint; the joint is slightly smaller than a pipe opening of the first connecting piece; and an anti-oxidation layer is arranged in the first connecting piece. The friction damage of the joint and the pipe opening of the first connecting piece is prevented due to the effect of the anti-oxidation layer, and the service life of a pipeline connector is prolonged. A convex ring made of fusion materials is arranged in the first connecting piece, pipes are connected in a hot fusion mode, and then the pipes needing to be connected are placed between the elbow connecting piece and a lining part. Meanwhile, due to the fact that the lining part is made of copper materials, the shape of the lining part is not likely to be affected during hot fusion, it is ensured that the inner walls of the connected pipes are not damaged, and the phenomenon of core blockage is avoided. When a heated pipe is connected with the convex ring made of the fusion materials, the convex ring seals the periphery of the pipe in a fusion mode to enable the connecting effect of the pipe to be better, and connecting is more convenient.

Description

Technical field [0001] The invention relates to a pipe connector, in particular to an elbow connector. Background technique [0002] Mankind has a long history of using pipeline transportation. With the development needs of various fields, people's understanding of pipeline materials and pipeline connection technology is constantly improving. Various pipes of different materials and pipe fittings of different connection methods are competing on the stage, bringing more and better choices to customers. Global requirements for pipelines According to data from the China Market Monitoring Center and other professional data, the global future annual pipeline demand growth will not be less than 16%, which will bring good business opportunities and greater profit space to the development of the pipeline industry. [0003] In the existing pipeline connectors, threaded connections are usually adopted. This connection method makes the installation of the pipeline connectors inconvenient and...

Problems solved by technology

[0003] In the existing pipeline connectors, threaded connections are usually used. This connection method makes the installation of the pipeline connectors inconvenient, and at the same time, the sealing performance is not good. It is easy to loose and leak under the condition of high pressure and high flow rate, and it is difficult to maintain.
