Abstract
Disclosed is a polyethylene electric fusion pipe covering wire. The polyethylene electric fusion pipe covering wire comprises a polyethylene electric fusion pipe, and resistance wires are arranged inside the polyethylene electric fusion pipe body. The polyethylene electric fusion pipe covering wire is characterized in that the outside of the resistance wire is provided with a polyethylene covering layer, and the cross section of the polyethylene covering layer is in a rectangular shape. The cross section of the polyethylene covering layer is made into the rectangular shape, the resistance wire is arranged in the center of the polyethylene covering layer, so that before injection molding of the polyethylene electric fusion pipe, the rectangular cross-sectional polyethylene covering layer is wound onto a mold core and compacted, then injection molding of the polyethylene covering layer can be performed, further the step of round wire scraping can be omitted, the working efficiency can be improved, and the production cost can be reduced; by means of the rectangular cross-sectional polyethylene covering layer, the compactness among polyethylene covering layers can be greatly enhanced, and the fusion quality among pipes can be ensured.
Description
Technical field
The utility model relates to polyethylene fused pipe, particularly relates to the covering thread of polyethylene fused pipe.
Background technique
Polyethylene fused pipe is to connect electro-fusion welding machine by wiring terminal, by electro-fusion welding machine, export constant voltage and supply with polyethylene electric-melting bellmouth pipe fitting and the polyvinyl piping materials having assembled, the resistive conductor that makes to be preset in pipe fitting produces heat, resistive conductor heats pipe fitting and tubing, the pipe fitting and the tubing molecular chain under certain pressure that reach molten state connect again, reach regulation rear tubular member weld interval and tubing and enter cooling stage, sub polyethylene subchain in the middle of cooling procedure in the middle of pipe fitting and tubing rearranges crystallization, to reach the object of pipe fitting and tubing welding.And have one deck clad outward at resistive conductor, clad plays a protective role to resistive conductor, the cross section of existing clad is all circular, when injection molding pipe part, to by one side scraping of circular clad, be first plane, again by the resistive conductor with clad by winding machine on core rod, using resistive conductor as inserts, carry out injection moulding, make like this clad can contact completely with core rod, and be conducive to the compacting of clad, the shortcoming of its existence is: the one side of circular clad is carried out to scraping, workman's workload is large, manufacturing efficiency is low, and scraping the polythene material chipping away slatterns, improved cost of production, befouling environment again.
Summary of the invention
The purpose of this utility model is the shortcoming existing in order to overcome prior art, a kind of production process that reduced is provided, improved working efficiency, reduced cost of production, and improved the compaction rate between each covering thread, guaranteed the covering thread of the polyethylene fused pipe of welding quality between pipe fitting and tubing.
The technological scheme of the covering thread of the utility model polyethylene fused pipe is: comprise polyethylene fused pipe, resistive conductor is set in polyethylene fused pipe, it is characterized in that: described resistive conductor has polyethylene clad outward, the cross section of described polyethylene clad is rectangle.
The utility model discloses a kind of covering thread of polyethylene fused pipe, by rectangle is made in the cross section of polyethylene clad, resistive conductor is arranged on the central position of polyethylene clad, before injection molded polyethylene electric melting pipe fittings, first use polyethylene clad that winding machine is rectangle by cross section on core rod, and carry out compacting work, then just can carry out injection molded polyethylene electric melting pipe fittings, save the step of existing scraping circle line, improved working efficiency, reduced cost of production, and adopt the polyethylene clad that cross section is rectangle, compaction rate between each polyethylene clad is improved greatly, thereby guaranteed the welding quality between pipe fitting and tubing.
Accompanying drawing explanation
Fig. 1 is the structural representation that covering thread is set in polyethylene fused pipe;
Fig. 2 is that the covering thread cross section of polyethylene fused pipe is foursquare structural representation;
Fig. 3 is that the covering thread cross section of polyethylene fused pipe is rectangular structural representation.
Embodiment
The utility model relates to a kind of covering thread of polyethylene fused pipe, as shown in Fig. 1-Fig. 3, comprise polyethylene fused pipe 1, resistive conductor 2 is set in polyethylene fused pipe, it is characterized in that: outside described resistive conductor 2, having polyethylene clad 3, the cross section of described polyethylene clad is rectangle.By rectangle is made in the cross section of polyethylene clad 3, resistive conductor 2 is arranged on the central position of polyethylene clad, before injection molded polyethylene electric melting pipe fittings 1, first use polyethylene clad 3 that winding machine is rectangle by cross section on core rod, and carry out compacting work, then just can carry out injection molded polyethylene electric melting pipe fittings 1, save the step of existing scraping circle line, improved working efficiency, reduced cost of production, and adopt the polyethylene clad 3 that cross section is rectangle, compaction rate between each polyethylene clad is improved greatly, thereby guaranteed the welding quality between pipe fitting and tubing.
Claims (1)
1. the covering thread of polyethylene fused pipe, comprise polyethylene fused pipe (1), resistive conductor (2) is set in polyethylene fused pipe, it is characterized in that: described resistive conductor (2) is outer polyethylene clad (3), and the cross section of described polyethylene clad is rectangle.
