Abstract
The utility model provides a novel plastic electro-fusion pipe fitting which comprises a pipe fitting body, a plastic coating layer and an electric heating wire, wherein the plastic coating layer is wrapped around the electric heating wire. The lower two thirds of the plastic coating layer which is wrapped on the end surface of the electric heating wire is square and the upper one third of the plastic coating layer which is wrapped on the end surface of the electric heating wire is of the shape of a two thirds circle. The surrounding part of the electric heating wire is wrapped with the square plastic coating layer. By adopting the technical scheme, the electric heating wire can be evenly arranged on the inner wall of the electro-fusion pipe fitting and is not apt to be exposed outside. Thereby, the electric heating wire is not apt to be oxidized, the heating is stable, the electric heating wire does not bounce and jump, the electro-fusion pipe fitting can be effectively fused during construction and the connection at a joint is tighter.
Description
Technical field
The utility model relates to a kind of novel plastic electrofusion pipe fitting.
Background technique
Existing plastic electrofusion pipe fitting, its processing method generally all are in course of working the electric heating wire that sequences to be put into injection mould, add injection molding then, make being wrapped in the plastic pipe of electric heating wire nature.Electric heating wire very easily is exposed to the internal surface of electric melting pipe fittings like this; electric heating wire makes moist easily and causes corrosion on the one hand; and oxidation easily; the electric conductivity of electric heating wire is changed; the situation that short circuit in work progress, occurs through regular meeting; make the plastic melt poor effect of electric melting pipe fittings, thereby cause the welding effect of pipe fitting bad, potential safety hazard occurs.
The model utility content
The purpose of this utility model provides a kind of novel plastic electrofusion pipe fitting, around electric heating wire, wrap up one deck plastic coating, electric heating wire is arranged on the inwall of electric melting pipe fittings uniformly, make electric heating wire be not easy oxidation, it is more stable to generate heat, and can guarantee electric heating wire not elater, do not jump silk, more can combine together through injection moulding with electric melting pipe fittings, avoid electric heating wire to be exposed to the pipe fitting internal surface.
In order to reach described effect, a kind of novel plastic electrofusion pipe fitting of the utility model comprises pipe fitting body, plastic coating, electric heating wire, described plastic coating be wrapped in electric heating wire around.The plastic coating of described electric heating wire end face below 2/3 part parcel is square, and electric heating wire end face top 1/3 partly plastic coating is 2/3 circle.Be wrapped in square plastic coating around the described electric heating wire.
Owing to adopted described technological scheme, electric heating wire can be arranged on the electric melting pipe fittings inwall uniformly, the outside that electric heating wire is not easy to expose, so be not easy to take place oxidation, it is more stable to generate heat, and electric heating wire not elater, do not jump silk, thereby during construction electric melting pipe fittings can high efficiency thawing to make that the joint connects tightr.

Embodiment
As Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, a kind of novel plastic electrofusion pipe fitting of the utility model comprises pipe fitting body (1), plastic coating (2), resistance wire (3), described plastic coating (2) be wrapped in electric heating wire (3) around.The plastic coating (2) of described electric heating wire (3) end face below 2/3 part parcel is square, and electric heating wire (3) end face top 1/3 partly plastic coating (2) is 2/3 circle.Described electric heating wire (3) is wrapped in square plastic coating (2) on every side.
Embodiment 1: the plastic coating (2) of described electric heating wire (3) end face below 2/3 part parcel is square, and electric heating wire (3) end face top 1/3 partly plastic coating (2) is 2/3 circle.Adopt double-deck plastic coating structure, convert electric energy to heat energy at when heating construction electric heating wire (3) and make the plastic pipe melt-through, therefore the molten electric heating wire (3) of holding of square plastic coating (2) that wrap up when electric heating wire (3) end face below 2/3 part this moment can not jumped out at once, because the round plastic coating of electric heating wire (3) end face top 1/3 part has in time been blocked electric heating wire (3), thereby avoided jumping the generation of silk phenomenon, guaranteed that pipe fitting can merge efficiently.
Embodiment 2: described electric heating wire (3) is wrapped in square plastic coating (2) on every side.In construction heating process because electric heating wire (3) around all be wrapped in plastic coating (2), before construction finished, electric heating wire (3) was jumped out in the heavy plastics coating (2) easily, had guaranteed the safety and the quality of construction.
The above only is a specific embodiment of the utility model, but structure characteristic of the present utility model is not limited thereto, any those skilled in the art is in field of the present utility model, and variation of being done or modification all are encompassed among the claim of the present utility model.
Claims (3)
1. a novel plastic electrofusion pipe fitting comprises pipe fitting body (1), plastic coating (2), electric heating wire (3), it is characterized in that: described plastic coating (2) be wrapped in electric heating wire (3) around.
2. a kind of novel plastic electrofusion pipe fitting as claimed in claim 1 is characterized in that: the plastic coating (2) of described electric heating wire (3) end face below 2/3 part parcel is for square, and electric heating wire (3) end face top 1/3 partly plastic coating (2) is 2/3 circle.
3. a kind of novel plastic electrofusion pipe fitting as claimed in claim 1 is characterized in that: described electric heating wire (3) is wrapped in square plastic coating (2) on every side.
