Embodiment Construction

[0018] The electric heating melting pad of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0019] Such as figure 1 , 2 As shown, the electric heating melting pad includes a thermoplastic pad 3, a conductive resistance wire 1 embedded in the thermoplastic pad 3 and distributed in the form of an Archimedes double helix, and two conductive electrodes 2 connected to the conductive resistance wire 1, The conductive electrodes 2 are arranged in grooves on the outer surface of the thermoplastic pad 3 .

[0020] Wherein the conductive resistance wire 1 is inlaid (or embedded) in the thermoplastic pad 3 according to the Archimedes double helix distribution. To prevent the distance from being too short, the conductive resistance wire 1 is exposed outside the thermoplastic pad 3 after being heated during the welding process, causing leakage. At the same time, the distance between the conductive resistance ...

Abstract

The invention discloses an electric melting pad and a method for connecting plastic pipelines or pipelines with pipeline end surfaces made from plastic by virtue of the same. The electric melting pad comprises a thermoplastic plastic pad, conductive resistance wires inlaid in the thermoplastic plastic pad and distributed in the form of Archimedes double helix, and two conductive electrodes connected with the conductive resistance wires, wherein the conductive electrodes are arranged in grooves in the external circular surface of the thermoplastic plastic pad; and the two plastic pipelines or the pipelines with pipeline end surfaces made from plastic can be connected by virtue of the electric melting pad. The conductive resistance wires in the electric melting pad disclosed by the invention are distributed in the form of Archimedes double helix, thus avoiding that one end of each of the conductive electrodes is arranged on the internal annular circular surface of the electric melting pad, and then preventing the possibility of outward leakage of a fluid along the conductive resistance wires, and the phenomenon of unbalanced heating of the parts of the electric melting pad can be avoided.

Description

technical field [0001] The invention relates to an electric heating pad, especially a plastic electric heating melting pad whose wiring mode of resistance wire is distributed by Archimedes double helix. Connection of plastic pipes or pipe ends with plastic material pipes. Background technique [0002] Based on the current connection methods of most plastic pipes, most of them are connected by electric melting sleeves, flanges, electric melting belts, etc. The cost of electrofusion sleeves, flanges, and electric melting belts is high, the production process is complicated, the connection procedures are many, the operation workload is large, the construction efficiency is low, the sealing reliability is poor, and the difficulties caused by inconvenience are urgently needed. connections to solve these problems. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an electric heating melting mat with simple structure, g...
