Abstract
The utility model relates to an embedded electric heating wire electric melting pipe fitting used for connecting plastic pipe fittings. Heating wires are arranged on the wall of the inner surface of the electric melting pipe fitting to avoid the oxide etch phenomena. The heating wires are easy to store. Simultaneously, the utility model reduces the high performance requirement for heating wires, and reduces cost. The plastic embedded electric heating wire electric melting pipe fitting has the advantages of reasonable structure and safe welding quality. The utility model is suitable for gas pipelines, heat distribution pipelines, chemical industry pipelines, food, sanitary, medicine, and other aspects.
Description
The utility model relates to a kind of flush type heating wire electrothermal smelting tube that plastic pipe is coupled together of being used for, and is particularly useful for the sweat soldering of polyethylene tube.
In the prior art, using electrothermal smelting tube couples together pipeline, by its scope one heater coil being installed between the connection surface is technique known, and along with the development of China's combustion gas cause and the plastic of fuel gas transportation pipeline, the application of electrothermal smelting tube is more extensive.What application was more at present is a kind of exposed heating wire electrothermal smelting tube, its heating wire is embedded on the inner surface of pipe fitting, heating wire directly contacts with air, dust is easily adhered in very easily oxide etch, surface, and stock's resting period directly influences the surface quality of pipe fitting, not thorough as surface treatment in construction, form dry joint easily, produce the seepage phenomenon, serious meeting causes combustion gas fire and explosion accident.
The purpose of this utility model be for overcome above-mentioned deficiency provide a kind of rational in infrastructure, welding quality is safe and reliable, the plastics flush type heating wire electrothermal smelting tube that cost is low.
The utility model is realized by following measure:
A kind of plastics flush type heating wire electrothermal smelting tube, sleeve pipe with opening hollow component of plastic material formation, the outer surface of sleeve pipe has two junction blocks at least, respectively be embedded with a molten hole bolt that expands near the junction block, imbed heating wire near in the internal surface of casing wall, and link with copper binding post in the hollow cavity of junction block, there is a locating ring at the inner surface middle part of sleeve pipe.Sleeve pipe is two logical types, and it is shaped as straight tube or elbow at any angle.Sleeve pipe also can be triplet type.In same electrothermal smelting tube, each sleeve pipe can be with footpath or reducing.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a cutaway view of the present utility model;
Among the figure: the molten hole bolt that expands of (1) sleeve pipe (2) copper binding post (3)
(4) heating wire (5) locating ring (6) junction block
The utility model is described in further detail below in conjunction with accompanying drawing:
A kind of plastics flush type heating wire electrothermal smelting tube, sleeve pipe (1) with opening hollow component of polythene material formation, on the outer surface of two logical type electrothermal smelting tubes, two junction blocks (6) are arranged as shown in Figure 1, be embedded with a molten hole bolt (3) that expands near the junction block, the sleeve pipe of injection mo(u)lding (1) is imbedded heating wire (4) near the wall inside spin distribution of inner surface, copper binding post (2) in the hollow cavity of heating wire and junction block (6) links, there is a locating ring (5) at the inner surface middle part of sleeve pipe, with the position of fixing required weld-end fittings.
When using the utility model, to insert the locating ring (5) at two ends to the middle part of flush type heating wire electrothermal smelting tube with the soldered pipeline sliding fit of material respectively locates, connect with the mains to binding post, make the heating wire energising, and set certain conduction time, the surface of electrothermal wire heating's fusion adjacent contact forms melt, and bloated hole fusion bolt overflows back outage automatically, can finish high-quality melting welding after the cooling and connect.
Electrothermal smelting tube of the present utility model has multiple shape, can also can be triplet type for straight tube shape or elbow at any angle, in same electrothermal smelting tube, each sleeve pipe can be with the footpath or reducing.Connect with the pipeline that adapts to various different demands.
The utility model has the advantage of: heating wire is arranged in the wall of electrothermal smelting tube inner surface, imbed plastics it In, with air insulated, having avoided air oxidation and the corrosion phenomenon of exposed structure generation, can reduce heating wire High performance requirement, thus cost reduced, and be easy to deposit, reduced the front cumbersome pretreatment process of construction. Fixing, be evenly distributed in the heating wire position, has avoided false weldering phenomenon in the melting welding. It is rational in infrastructure, has increased substantially Welding quality, safe and reliable has been filled up domestic blank, and has been reached domestic and international advanced level. The utility model Be applicable to the each side such as combustion gas pipeline, heating power pipeline, chemical industry pipeline, food, health, medicine, using value ten Divide extensively.
