Abstract
The utility model relates to an electric melting pipe fitting with a built-in heating wire. The electric melting pipe fitting comprises an electric melting pipe body and a pipe material, wherein the inner diameter of the electric melting pipe body is matched with the outer diameter of the pipe material, the inner wall of the electric melting pipe body is provided with a wire slot, the heating wire is arranged in the wire slot, an electrode pole is arranged in the electric melting pipe body, and the heating wire is electrically connected with the electrode pole. In the electric melting pipe fitting of the utility model, the heating wire is completely accommodated inside the pipe body, the problems of oxidation of exposed heating wire and short circuit during welding are solved, and the problem of heating wire shifting caused by impact during pipe material sheathing in construction is also solved.
Description
Technical field
The utility model relates to the electric melting pipe fittings of a kind of connection pipe fitting of pipeline, particularly a kind of embedded electric heating wire.
Background technique
The energy resource structure of China changes, and the upsurge that the laying combustion gas is looked around arrives, preferential " West-east Gas engineering, the tubing that needs are withstand voltage in a large number, corrosion-resistant and seal for pipe joints is good of implementing to reach 4000km in China western provinces Development Strategy.Wherein the PE pipeline is with its Economy, corrosion-resistant, flexible excellence." trenchless technology " adopted in construction.Greatly reduce and manufacture a finished product, improved efficiency of construction.Superiority has obtained extensive use to reach 50 years working life etc.
PE tubing electric smelting welding basic principle is by giving the electric heating wire energising that is embedded in pipe fitting inner wall heating, melting zone partly plastic resin is undergone phase transition, polymer segment interpenetrates, interweaves under certain pressure, arrange by cooling material crystallization again, make the fusion position be combined into a firm integral body.
Present electric melting pipe fittings is the exposed type of electric heating wire, and its electric heating wire (resistance wire) is exposed in the air, and is oxidized easily, thereby the performance of electric heating wire is changed, and causes the welding effect of pipe fitting and tubing to descend.Simultaneously, electric heating wire is exposed to be easy to when tubing is inserted in pipe fitting outside, and electric heating wire produces displacement, causes short circuit during welding, and welding job can't be carried out.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of electric heating wire to be hidden in the electric melting pipe fittings body interior, has avoided the oxidized and welding of electric heating wire the time to cause the electric melting pipe fittings of short circuit.
A kind of electric melting pipe fittings of embedded electric heating wire, described electric melting pipe fittings comprises electric smelting body and tubing, the internal diameter of electric smelting body and the external diameter of tubing are complementary, have wire casing on the electric smelting inboard wall of tube body, be placed with electric heating wire in the wire casing, be provided with electrode column in the electric smelting body, electric heating wire is electrically connected with electrode column.
Preferably, described electric heating wire is coated with ambroin.Be to collide in the oxidized and construction and installation process of electrically-heated-wire in order to prevent like this, electrically-heated-wire is superimposed and causes short circuit.
Electric melting pipe fittings of the present utility model can adopt following method manufacturing and get:
Electric heating wire backguy: at electric heating wire outer wrapping polyethylene raw material;
Fixing electric heating wire: electric heating wire adopts the aluminium pin to be connected with the riveted joint form with wiring terminal one end;
Wiring: fixed electrode post on the mould plug, coiling then;
Disposable injection moulding: the core that will connect up is sent into and is carried out disposable injection moulding in the mould, and electric heating wire is embedded in the electric melting pipe fittings;
Remove plug: after treating finished product cooling, adopt knockout with the demoulding from the plug of complete pipe fitting.
In the electric melting pipe fittings of the present utility model, electric heating wire is included in pipe fitting inside fully, has solved electric heating wire because of exposed and oxidized and welding the time cause problem of short-circuit, the displacement problem that when also having solved in construction socket tubing the bump of electric heating wire has been produced.
Description of drawings
Fig. 1 is the structural representation of the utility model electric melting pipe fittings.
Embodiment
Below in conjunction with embodiment and accompanying drawing the technical solution of the utility model is further elaborated, but protection domain of the present utility model is not limited to this.
With reference to Fig. 1, a kind of electric melting pipe fittings of embedded electric heating wire, described electric melting pipe fittings comprises electric smelting body 1 and tubing 2, the external diameter of the internal diameter of electric smelting body 1 and tubing 2 is complementary, have wire casing on the electric smelting inboard wall of tube body, be placed with electric heating wire 3 in the wire casing, be provided with electrode column 4 in the electric smelting body, electric heating wire 3 is electrically connected with electrode column 4.Described electric heating wire 3 is coated with ambroin 5.
