Abstract
The utility model provides a hidden heating wire type electric melting plastic pipe fitting. Wherein, a heating wire is mounted in the wall of the plastic pipe fitting by injection molding on both ends, the two ends of the heating wire are connected to an electric plug, the electric plug is connected vertically to the main axis of the pipe fittings in a plug sheath on the pipe fitting, and a welded watch column hole is made on the outer wall of the pipe fitting at inner side of the plug sheath. The utility model is novel in structure and innovative in design; with the hidden heating wire, the pipe fitting can be socket jointed to the pipe conveniently and welded evenly, and thereby stable quality is achieved, and the impact strength of the pipe fitting against external force is enhanced greatly; in addition, short circuit of the heating wire caused by thermal melting of the plastic material can be avoided; the utility model is suitable for use on various plastic pipelines, and especially suitable for use on high pressure gas or liquid transmission pipelines (e.g., natural gas and coal gas pipelines), and is a novel electric melting plastic pipe fitting.
Description
Technical field
The utility model relates to a kind of plastic pipe coupling compoonent, but the plastic pipe that especially a kind of melting welding connects.
Background technique
Along with the continuous development and the extensive use of plastic pipe, also more and more higher to its requirement of plastic pipe of joining logotype.In known technology, existing plastic pipe such as plastic sleeve, plastic three-way, plastics reduction nipple, plastic elbow etc. mainly are overall plastic structures, being connected with pipeline is to adopt the electric smelting welding, limit by the melting welding operating procedure, its soldered connects uneven, what have has a rosin joint, directly influence pipeline quality, and operating procedure is loaded down with trivial details; What also have directly twines electric heating wire on pipe fitting, but easily interrupts electric heating wire and because the mobile extruding of plastic raw material often causes the electric heating wire short circuit, bring inconvenience to use when pipe fitting connects.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of novel structure, operate simple and easy, melting welding seam evenly firmly, novel plastic pipe fitting easy to use.
The technical scheme in the invention for solving the technical problem is: will hide electric heating wire in the injection moulding in the pipe wall at plastic pipe two pipe nipple places, the two ends of electric heating wire are connecting electrical plug respectively, electrical plug and pipe fitting main axis are vertically connected in the plug boot of pipe fitting, and on the pipe fitting outer wall of plug boot inboard, be shaped on welding observation post hole, the injection moulded electric heating wire's electric melting plastic pipe that consists of.Electric melting pipe fittings comprises: electric smelting leads directly to that sleeve pipe, electric smelting reducing sleeve pipe, electric smelting threeway, electric smelting elbow, electric smelting saddle are straight-through, electric smelting saddle type bypass, electric smelting are repaired pipe fittings such as saddle.The utility model connects when installing, the plastic pipe that needs connection is inserted at the two ends of pipe fitting, the electric mortiser post of pipe fitting connects electric welding machine, start welding machine by designing requirement, just can automatically pipe and pipe fitting be connected as one, also can realize branch pipe tee connection connection, blocking Leakage connection, pipe pressurized adapter operation etc. on demand.
Because technique scheme is adopted in the utility model design, through testing on probation showing for several times, it has novel structure, design innovation, hide electric heating wire, make that the grafting of pipe fitting and pipeline is convenient and welding is evenly tight, steady quality, can improve the external shock resistance ability of pipe fitting again greatly, can avoid simultaneously adapting to various plastic pipe owing to advantages such as the plastic raw material Heated Flow are pushed the electric heating wire short circuit that causes, and operation is easy, especially also adapting to high pressure air body, liquid conducting pipes such as rock gas, coal gas, is a kind of novel electric melting plastic pipe.
