Saddle-shaped electric heating melting connection sheet for PE pipeline, and preparation method thereof

Abstract

The invention discloses a saddle-shaped electric heating melting connection sheet for a PE pipeline, and a preparation method thereof. The connection sheet comprises a saddle-shaped sheet, an electric heating wire and an electricity-connecting pipe, wherein the electric heating wire is rolled to be S-shaped, repeatedly wound into a circle and arranged at the two sides of the saddle-shaped sheet, and an end head of the electric heating wire is connected to the electricity-connecting pipe in a penetrating manner; the electricity-connecting pipe comprises a copper column and a protection ring, two through holes are formed in the copper column, and the protection ring is molded from a PE material through injection and installed on an outer ring of the copper column; and the end head of the electric heating wire is connected into the through holes in the copper column in a penetrating manner. The invention further discloses a preparation method of the saddle-shaped electric heating melting connection sheet for the PE pipeline. The saddle-shaped electric heating melting connection sheet for the PE pipeline, and the preparation method thereof are used for connection for a saddle-shaped pipe fitting of the PE pipeline; the connection sheet is reasonable in structure and ingenious in preparation steps; the aperture size of the connection sheet is increased, and the application range of the saddle-shaped electric heating melting connection sheet for the PE pipeline is expanded; and a good application prospect and a high promotion value are achieved.

Description

technical field [0001] The invention relates to the technical field of welding of plastic pipe fittings, in particular to a PE pipe saddle-shaped electrothermal fusion connecting piece and a preparation method thereof. Background technique [0002] PE plastic pipes have been introduced into my country for more than 20 years, and are widely used in chemical industry, natural gas, tap water, sewage treatment, farmland irrigation, logistics transportation, communication, electric power and other fields. [0003] Among PE plastic pipes, saddle-shaped pipe fittings are the main components to realize the main line branch, which can make the transmission pipe network present the diversity of network distribution. Install saddle-shaped pipe fittings corresponding to the pipeline specifications at the pipelines that need to be branched or realize tees, and use hot-melt connection or electric fusion connection to realize the permanent connection between saddle-shaped pipe fittings and...

AI Technical Summary

Problems solved by technology

[0004] The saddle-shaped electric heating connection piece of PE pipe is a key part of the hot-melt connection. At present, the outer diameter of the connection piece used in the field is not more than 90mm, and the outer dimension of the connection piece is too small, which limits the saddle-shaped electric heating of PE pipe to a certain extent. The application range of the fusion connection piece affects the application prospect of the saddle-shaped pipe fittings connected by the hot-melt method
