Problems solved by technology

Then, when using hemp silk and PTFE raw material for sealing connection, too little PTFE raw material wrapped will easily lead to insufficient sealing, and too much PTFE raw material wound will result in too much margin. It is not easy to install, and it may cause blockage of the inner wall of the pipeline, and also affect the appearance; when the liquid raw material belt is directly used, although the problem of sealing is solved, it is not easy to disassemble, and it also pollutes the water quality, and it is not easy to disassemble, resulting in Difficult to maintain

Abstract

The invention discloses a pipe fitting. The pipe fitting comprises a pipe body, a sealing part and a screw cap, wherein outer threads are arranged on the outer wall of the pipe body, first internal threads are arranged on the inner wall of the pipe body, the first internal threads are used for connecting a pipeline, the screw cap is provided with second internal threads, the external threads are in threaded fit with the second internal threads so as to make the sealing part press the outer wall of the pipeline, and then seal a gap between the inner wall of the pipe body and the outer wall of the pipeline. According to the pipe fitting, installing and disassembly are convenient, the maintenance is easier, in addition, the problems of water quality pollution caused by using a liquid raw material belt and inconvenient disassembly and maintenance are avoided, meanwhile, usage of a polytetrafluoroethylene raw material is also avoided, so that the phenomenon that the inner wall of the pipeline is blocked by the polytetrafluoroethylene raw material is avoided.

Description

technical field [0001] The invention relates to the technical field of connectors, in particular to pipes. Background technique [0002] Existing rigid pressure-bearing pipes generally need to be connected with screws (that is, threaded connections), and it is necessary to wind the PTFE raw material after hemping the external thread of the pipe fitting, or directly coating the liquid raw material on the thread. Then directly connect the pipe fittings to the pipeline, so as to ensure that the pipe fittings and pipes are connected with sufficient sealing. Then, when hemp silk and PTFE raw material are used for sealing connection, too little PTFE raw material wound will easily lead to insufficient sealing, and too much PTFE raw material wound will result in too much margin. It is not easy to install, and it may cause blockage of the inner wall of the pipeline and affect the appearance; when the liquid raw material belt is directly used, although the problem of sealing is solve...
