Description

Wiring type PE combustion gas electric melting pipe fittings
Technical field
The utility model relates to the electric melting pipe fittings field, refers in particular to a kind of wiring type PE combustion gas electric melting pipe fittings.
Background technique
Electric melting pipe fittings has been widely used in combustion gas, water, chemical industry and communications industry.The PE electric melting pipe fittings product of using always both at home and abroad mainly can be divided at present: bareing, sealed mode, enameled cable formula.1, bareing electric melting pipe fittings: directly with resistance wire by machine or be manually wrapped on the mould fuse, injection moulding success.Shortcoming is to cause the easy oxidation of resistance wire outside because resistance wire is exposed, has a strong impact on welding performance, and resistance wire by the tubing roof fall, causes short circuit easily in addition.2, sealed mode electric melting pipe fittings: cover in first injection moulding one deck PE film, then interior cover surperficial around on resistance wire, put into mould together with fuse at last and carry out quadric injection mould.So just resistance wire is completely contained in pipe fitting inner wall, resistance wire can or not come off in oxidation yet, and shortcoming is that the pipe fitting internal surface has oxide layer, influence heat conduction, and resistance wire is far away apart from tubing, and pipe part can not melt synchronously.3, enameled cable formula electric melting pipe fittings: earlier the resistance wire outer surface is applied one deck with the PE material of pipe fitting body with material, make enameled cable, the same with bareing then, enameled cable directly is wrapped on the fuse once-through.Shortcoming is that the surface has oxide layer, influences welding effect.And these three kinds have a common shortcoming is exactly that the endoporus ovality is bigger, causes melt zone inhomogeneous, influences welding effect.
Summary of the invention
For overcoming the above problems, the utility model provides a kind of can prevent the naked leakage of resistance wire and the wiring type PE combustion gas electric melting pipe fittings of oxidation and pipe fitting inner wall oxidation.
Wiring type PE combustion gas electric melting pipe fittings comprises the injection moulding pipe fitting, and copper cash and wiring terminal, wiring terminal are installed in the two ends of injection moulding pipe fitting, and wiring terminal is connected with copper cash by resistance wire, and described copper wire cloth is in the inside of injection moulding pipe fitting internal surface.
As a kind of improvement of the present utility model, described injection moulding pipe fitting is provided with 3 cooling zones and 2 melt zone, and the cooling zone is distributed in two ends and the neutral position of injection moulding pipe fitting, and melt zone is located between the adjacent cooling zone.
Further improve as of the present utility model, the copper cash of described melt zone is arranged intensive.
As a kind of improvement of the present utility model, be provided with groove in the middle of the described injection moulding pipe fitting inner wall, baffle ring is installed on the groove.
It is that copper cash does not expose that the utility model adopts degree of depth wiring, prevents the copper cash oxidation; The pipe fitting inner wall of avoiding being produced by enameled cable has the problem of oxide layer; Also solved the problem of endoporus ovality large eccentricity.The copper cash of melt zone of the present utility model is arranged intensive, and after the electric melting pipe fittings energising, seal operation is carried out in the cooling zone, two ends, and plastics in the middle of melt zone is melted are covered in tube surfaces.The utility model also is provided with baffle ring, is used for fixedly tubing insertion depth.
