The model utility content
The utility model uses the hot melt pipe cap to power up molten sleeve combination mode in use in order to substitute in the prior art; Can reach low-cost, safe and reliable electric smelting and connect, also give the convenience of constructing in using, thus brand-new a kind of polyethylene electric smelting pipe cap of research and development.It adopts the electric heating wire welding, has solved the blank during polyethylene tube connects in the existing technology.
The technological scheme that the utility model adopts is following:
A kind of polyethylene electric smelting pipe cap comprises electric smelting body 1.
In practical implementation, heating element adopts electric heating wire 4, and electric heating wire 4 helical disks are laid on melting zone 6 internal surfaces, and a joint is drawn at electric heating wire 4 two ends respectively, and two joints pass electric smelting body 1 respectively, and is electrically connected with wiring terminal 2 lower ends through copper pin form.
In practical implementation, connect effect in order to reach good electric heating, electric heating wire 4 adopts plain conductor, and its meter resistance is 2 Ω/m, and the silk footpath is 0.4mm, and the service voltage of electric smelting welding is 39.5 ± 0.5V.
In practical implementation:
For the ease of observing and understanding the molten welding situation of electric heating in the operating process, electric smelting body 1 outer surface is provided with the peep hole 5 that is communicated with external environment condition and melting zone 6, and peep hole 5 is arranged on melting zone 6 tops.
The nominal diameter of electric smelting body 1 is a kind of among dn32, dn40, dn50, the dn63.
The material of electric smelting body 1 is a polyethylene.
The electric smelting pipe cap that the utility model provides has replaced hot melt pipe cap in the past to power up the compound mode of molten sleeve, has reduced fabricating cost, reduces and beautified the outward appearance volume; In addition, this electric smelting pipe cap once welds and only uses melting zone energising heating, has replaced the heating of switching on jointly of two melting zones in the past, has improved safety reliability, makes operation easier, has improved efficiency simultaneously.Can be widely used in each field such as combustion gas, feedwater, oil, chemical industry, mining, row are dragged for, underground heat.

Embodiment
A kind of polyethylene electric smelting pipe cap as shown in Figure 1 comprises electric smelting body 1, and body is made up of the polyethylene material, and electric smelting body 1 inside is provided with melting zone 6, is provided with electric heating wire 4 in the melting zone 6, and electric heating wire 4 helical disks are laid on melting zone 6 internal surfaces.
The upper surface of electric smelting body 1 is provided with pair of terminals, and each tenminal block comprises wiring terminal 2 and wiring cavity 3.
A joint is drawn at electric heating wire 4 two ends respectively, and two joints pass electric smelting body 1 respectively, and is electrically connected with wiring terminal 2 lower ends through copper pin form.
Electric heating wire 4 adopts plain conductor, and its meter resistance is 2 Ω/m, and the silk footpath is 0.4mm, and the service voltage of electric smelting welding is 39.5 ± 0.5V.
The concrete operating process of the utility model is following:
Tubing that is soldered or pipe fitting are scraped off oxide layer; It is inserted in polyethylene electric smelting pipe cap put in place, connect two wiring terminals on the polyethylene electric smelting pipe cap, under the effect of normal voltage energising; To making the electrothermal wire heating who is connected on the wiring terminal; Be viscous state to the polyethylene resin on the melting zone on tubing or pipe fitting and the polyethylene electric smelting pipe cap, be energized to the stipulated time, interrupt power supply; Static cooling changes vitreous state into and reaches the high tenacity welding purpose with plastic pipe thereby make polyethylene resin be viscous state at last.
Use the electric smelting connection procedure of electric melting pipe fittings to accomplish,, physical environment and artificial factor are reduced greatly, have effect preferably improving welding quality through fully automatic electric fusing soldering welder control welding process through the fully automatic electric fusing soldering welder.
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, after welding is accomplished, stop; 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.
