Abstract

The invention provides a fused pipe fitting enabling pipes of different materials to be connected. The pipe fitting comprises a plurality of tubular plastic connecting ends of different materials anda metal piece communicating with the multiple plastic connecting ends. The metal piece is used for enabling the multiple plastic connecting ends to communicate with each other and connected and fixedto the multiple plastic connecting ends in a sealed mode. Resistance wires are arranged on the inner surfaces of the plastic connecting ends correspondingly. According to the fused pipe fitting, through the multiple plastic connecting ends of the different materials and the metal piece used for enabling the multiple plastic connecting ends to communicate with each other, the fused pipe fitting ismade to have the effect that the fused pipe fitting is in fused connection with the multiple pipes of the different materials.

Description

technical field [0001] The invention relates to the field of electric fusion pipe fittings, in particular to an electric fusion pipe fitting for connecting pipes of different materials. Background technique [0002] In recent years, plastic pipes have been used more and more in the fields of gas, water supply and drainage. With the development of pipeline technology, the requirements for the pressure resistance of the pipeline are getting higher and higher, and at the same time, higher requirements are put forward for the connecting pipe fittings between the pipelines. [0003] Pipes made of different materials cannot be connected by conventional hot-melt welding due to the large difference in raw material properties and poor compatibility. Usually, when connecting pipes of different materials, mechanical connection methods such as flange connection and screw connection are used, but the service life of this connection method is shorter than that of the pipe body. For exam...
