Embodiment
Below in conjunction with embodiment, the utility model made further specify.
As shown in Figure 1, a kind of electric smelting bend pipe tools comprises one section hollow electric smelting body 1 that is an angle of 90 degrees bending, and its material is polyethylene, and the two ends of electric smelting body 1 are hot melt connecting end 7, and the inner chamber of hot melt connecting end 7 is melting zone 6, is provided with electric heating wire 4 in the melting zone.
The nominal diameter of electric smelting body 1 is dn250mm.
The outer wall of electric smelting body 1 is provided with pair of terminals, and tenminal block comprises wiring terminal 2 and wiring cavity 3, and the input voltage that loads on the wiring terminal 2 is 39.5v.
The rice resistance of electric heating wire 4 is 0.04859 Ω/m, and string diameter is φ 1.3mm.
The hot melt insertion depth of hot melt connecting end 7 is 120mm.
Specific operation process of the present utility model is as follows.
Soldered pipeline is scraped off oxide layer, pipeline is inserted in the pipe fitting, by the tenminal block on the electric melting pipe fittings wire coil energising is made it heating, under the effect that heat is transmitted, increase along with heating time, resin on pipe fitting and the pipeline junction surface is viscous state, is energized to the stipulated time, interrupts power supply, the junction surface cooling, reaches plastic pipe height welding purpose thereby make the resin of fusing change vitreous state into.
Electric smelting connection procedure with electric melting pipe fittings can be finished by Full-automatic electric fusion welding machine, by Full-automatic electric fusion welding machine control welding process, the impact of physical environment and personal factor is reduced greatly, has preferably effect to improving welding quality.
Electric melting pipe fittings is in welding process, be arranged in the peep hole on the outer surface of pipe fitting housing material slowly jack-up until welding stop after finishing, the material of the jack-up on peep hole surface helps to carry out assistant identification with the method for range estimation to being welded on the welding situation, and is very convenient.
