Abstract

The utility model relates to an electric thermal-fusing jointing piece for jointing thermoplastic pipes. The utility model has the advantages of reasonable structure, low cost, reliable welding quality and various shapes. The utility model can be applied to the thermal-fusing welding of plastics pipes. The utility model is particularly suitable for polyethylene pipes with different shapes.

Description

Plastic pipe electric heating melts link
The utility model relates to a kind of electric heating that is used for pipes consisting of thermoplastic plastics is coupled together and melts link.
With the pullover connecting tube of thermoplastic material, it is known by its scope one heating coil being installed between the connection surface, and for example West Germany's specification of exhibition 1048106 is described.But in the implementation process of many patents,, the quality problems of some serious thermal fusion weldings can occur, influence the plastic tube welding reliability widely owing to its hot melt link unreasonable structure.Simultaneously, because the hot melt link shape of most of patents is essentially straight shape two siphunculus head, and the link of special shapes such as elbow, three-way type, four-way type, reducing and plug is rarely found, has been subjected to significant limitation in actual application.
The purpose of this utility model is to overcome the defective that exists in the above-mentioned prior art, the molten link of a kind of plastics electric heating rational in infrastructure, that cost is lower, reliable welding quality, shape are various is proposed, it can be applied to be particularly useful for difform polyethylene tube in the sweat soldering of plastic tube.
To achieve these goals, the inventor has proposed the molten link of a kind of plastic pipe electric heating, this link is an opening hollow component that is made of thermoplastic material, open interior is made up of garden cylindricality sleeve pipe, internal surface is embedded with the wire that is used to heat, used wire is conventional metallic conductor, and the length and the spacing of the coil of being made up of wire should get by calculating according to resistance value wiry.Have two tenminal blocks on the outer surface of link at least, this tenminal block is made up of the hollow cavity of connecting the link inner and outer surface and the wiring terminal that joins with the heating of metal silk wherein.Internal surface middle part at link has the position of a center fixation pin with fixing required weld-end fittings at least.Respectively be embedded with a molten bolt that expands near the tenminal block.
Describe the utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is the schematic representation of the utility model two logical type links, it is an opening hollow component that is made of thermoplastic material, open interior is a garden cylindricality sleeve pipe 1, be distributed with one group of wire that is used to heat 2 on the internal surface spirally, on the outer surface of these two logical type links, two tenminal blocks 3,4 are arranged, this tenminal block is made up of hollow cavity that links to each other with the link outer surface and the wiring terminal 6 that joins with the heating of metal silk wherein, there are four center fixation pins 5 at internal surface middle part at this two logical type link, with the position of fixing required weld-end fittings.Near tenminal block 3,4, respectively be embedded with a molten bolt 7 that expands.
Link described in the utility model has multiple shape, except that two perfectly straight casts, also can be the elbow with several angle, three-way type, four-way type and plug etc., and in a connection piece, each sleeve pipe can be with the footpath, Different Diameter, or reducing.
Purpose described in the utility model is achieved like this, with soldered plastic pipe, each port from the molten link of electric heating inserts in it respectively, center fixation pin in the link is located, by the tenminal block on the link wire coil is switched on, through behind the certain hour, the heat energy that wire coil produced can make the plastic pipe fusing of link and adjacency, thereby reaches the purpose with the high-quality welding of plastic pipe.
In sum, the utility model compared with prior art has following advantage, at first, heating coil is arranged on the internal surface of link, embeds among the plastics fixed-site, and has a rational distribution, can not produce the danger that heating wire moves and the possibility of local superheating, welding quality is good, good reliability.Simultaneously,, can make the pipe fitting that is welded be easy to fix, not produce and depart from, protect welding quality owing to be provided with the center fixation pin in the link.In addition, owing to link variation in shape, enlarged its purposes widely.
