Polyethylene of the present invention (PE) electric melting pipe fittings, since take 〉=110v ,≤the 230v scope in as 110v, 160v, 200v, 220v, 230v etc. down the enforcement pipe fittings be connected with the electric smelting of tubing, make electro-fusion welding machine realization miniaturization, thereby move easier, easy to operate, improved usefulness simultaneously.
The pipeline that electric melting pipe fittings of the present invention connects can be widely used in each field such as combustion gas, feedwater, oil, chemical industry, mining, irrigation and drainage, sewage discharge geothermal utilization.
Description of drawings
Accompanying drawing 1 is polyethylene electric smelting elbow circuit diagram of the present invention
The specific embodiment
The present invention will be described below in conjunction with accompanying drawing
Accompanying drawing 1,2 is 90 ° of electric smelting elbows of polyethylene of the present invention (PE) schematic diagram.
(1) is the pipe fitting body; (2) be binding post; (3) be melting zone.
Heating wire is embedded on the inwall of pipe fitting body (1), is distributed in melting zone (3) scope, and its two ends adopt the riveted joint form to link to each other with two binding posts (2) by the aluminium pin.When carrying out the electric smelting welding, the interface of electro-fusion welding machine and pipe fitting binding post (2) are pegged graft, and the output voltage of electro-fusion welding machine is 220v, presses the electro-fusion welding machine button, can carry out the electric smelting welding.
Concrete operating process is: with soldered plastic conduit, each end bell from electric melting pipe fittings inserts in it respectively, center fixation pin in the electric melting pipe fittings is located, and by the binding post on the electric melting pipe fittings wire coil is switched on, and makes it heating, under the effect that heat is transmitted, at first the resin near heating wire is heated fusion on the electric melting pipe fittings, and causes volumetric expansion, and the resin of fusion subsequently begins to expand, along with the increase of heat time heating time, the resin of pipe fitting and tubing joint face is viscous state.Be energized to the stipulated time, interruptive current, the joint face cooling makes the resin of fusing change glassy state into, thereby reaches the purpose with the high-quality welding of plastic pipe.
Heating wire of the present invention is the plain conductor of exposed plain conductor or cladding plastic insulating layer.
Use the electro-fusion welding connection procedure of electric melting pipe fittings to finish by the fully automatic electric fusing soldering welder.By fully automatic electric fusing soldering welder control welding process, natural environment and artificial factor are reduced greatly, have effect preferably to improving welding quality.
Electric melting pipe fittings is in welding process, be arranged in the observation indicator hole on the housing outer surface slowly jack-up of material, after welding is finished, stop the material of peep hole surface jack-up, help solder side welding situation to be carried out assistant identification with the method for range estimation, very convenient.
The present invention has improved the inner surface that the usefulness heater coil is embedded in electric melting pipe fittings, is embedded in the plastics, and fixed-site, and have rational distribution can not produce the danger that heater strip moves and the possibility of hot-spot, and welding quality is good, good reliability; And, adopt the electric melting pipe fittings of cladding plastic insulating layer, can prevent since heating wire owing to be exposed in the air oxidation or because mechanical damage influences welding process even cause melting welding to be failed, simultaneously, owing to be provided with the center fixation pin in the electric melting pipe fittings, can make the pipe fitting that is welded be easy to be decided to be, not produce and depart from, favourable to welding quality.Observation indicator hole on the housing outer surface can intuitively be observed the connection situation after the electric heating fusion welding.In addition, owing to electric melting pipe fittings variation in shape, enlarged its purposes greatly.
In sum, the present invention compared with prior art has following outstanding advantage, the present invention and common Under≤40v voltage, implement polyethylene (PE) the electric melting pipe fittings difference of electric fusion welding, polyethylene of the present invention (PE) Electric melting pipe fittings 〉=110v ,≤implement pipe fitting under a certain voltage in the 210v scope to be connected with the electric smelting of tubing, Make electro-fusion welding machine realize miniaturization, thereby move easily, handled easily has improved usefulness simultaneously.
