The utility model discloses the cross section is made for the heating wire of rectangle to cladding PE material layer outside the heating wire, replaces the line butt fusion technique of original cylinder heating wire with the butt fusion technique of face and face, closely the arranging and the hot melt connection of adjacent heating wire of the heating wire of being convenient for, and its reasonable in design, simple manufacture, it is with low costs, the cross -section rectangle size of heating wire can design according to wiring requirement and pipeline bore specification, flexible and diverse, and application scope is wide, can satisfy the wiring requirement of heavy -calibre and super large bore pipe connection mouth, is applicable to multidimension wiring mode.
Description
Technical field
The utility model relates to the electric melting connection technical field of plastic conduit industry, is specifically related to a kind of coated heating wire of rectangle PE being wound around welding.
Background technology
Before the more than ten years, socket joint electric heating melting (PE) pipe fitting has just been produced in Ningbo " space China ", in succession had Yuyao " celebrating is sent out " afterwards, enterprises such as Zhejiang " newly large ", the technology of these producers is all imitative external, and be all run-in index socket joint type, the wiring of run-in index socket joint is a direction, is connected up by heating wire winding, put plug into injection mold afterwards on plug, after injection moulding cooling, form a socket joint electrothermal smelting tube.At present, the coated heating wire of PE is generally cylindrical, and be that line connects during adjacent heating wire hot-melt adhesive paste, degree of being connected firmly is not high, and evenness is poor; In addition, heavy caliber taper socket joint and zigzag socket joint electric melting connection technology make first appearance, it relates to the wiring problem of two-dimensional directional, higher requirement has been had to the arrangement tightness between adjacent heating wire and adhesion strength, cylindrical heating wire is not suitable for two-dimensional directional wiring, therefore, a kind of model electrically-heated-line being applicable to two-dimensional directional wiring is needed at present badly.
Utility model content
The purpose of this utility model is to provide a kind of coated heating wire of rectangle PE being wound around welding, be the technical problem that line connects, degree of being connected firmly is not high, evenness is poor when solving the coated heating wire of cylindrical PE adjacent heating wire hot-melt adhesive paste in prior art, and arrangement tightness between adjacent heating wire and adhesion strength can not meet the technical problem of the two-dimensional directional cabling requirement of heavy caliber taper socket joint and zigzag socket joint electric melting connection.
For realizing above-mentioned technical purpose, the utility model takes following technical scheme:
Be wound around the coated heating wire of rectangle PE of welding, its inner core is heating wire, it is characterized in that: described heating wire is coated with polythene material, and the cross section being coated with the heating wire of polythene material is rectangle.
As preferred technical scheme, the welding layer that described polythene material is divided into the integument of internal layer to be connected for adjacent two heating wires with skin.
Preferably, described integument is the polythene material layer heating wire initial stage adhering to polythene material formation, and its cross section is circular, and the thickness range of integument is 2 ~ 4mm.
Further preferred, the polythene material layer of described welding layer to be the shaping cross section of post-production be rectangle, the length range of rectangle is 6 ~ 8mm, and width range is 4 ~ 6mm.
Preferably, described polythene material is high density polyethylene, as oil of SPC product 041, Qilu Petrochemical 2480, husky Bick produce 6006 and Borealis 3490/3440 etc.
Preferred, described heating wire can be 1 ~ 5.
Compared with prior art, technical advantage of the present utility model is:
1, the utility model is at heating wire outer cladding PE material layer, make the heating wire that cross section is rectangle, the fusion techniques of original cylinder heating wire is replaced by the fusion techniques in face and face, the hot melt row of the tight arrangement and adjacent heating wire of being convenient to heating wire connects, it is reasonable in design, make simple, cost is low;
2, the cross section rectangular dimension of heating wire can design according to cabling requirement and pipe diameter specification, versatile and flexible, applied widely, can meet the cabling requirement of heavy caliber and ultra-large-diameterpipeline pipeline connector, be applicable to multidimensional wire laying mode;
3, owing to being designed to rectangle covering thread, face of weld can be made after wiring smooth, smooth, largely promote welding quality.
Accompanying drawing explanation
Fig. 1 is the cross sectional representation of the coated heating wire of rectangle PE of the be wound around welding that the utility model relates to.
Reference numeral: 1-heating wire, 2-integument, 3-welding layer.
Embodiment
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
Be wound around the coated heating wire of rectangle PE of welding, its inner core is heating wire 1, it is characterized in that: heating wire 1 is coated with polythene material, and the cross section being coated with the heating wire of polythene material is rectangle.Polythene material is divided into the integument 2 of internal layer and outer field welding layer 3.The polythene material layer that integument 2 is formed for heating wire initial stage adhesion polythene material, its cross section is circular, and the thickness range of integument 2 is 2 ~ 4mm.The polythene material layer of welding layer 3 to be the shaping cross section of post-production be rectangle, length (L in Fig. 1) scope of rectangle is 6 ~ 8mm, and width (H in Fig. 1) scope is 4 ~ 6mm.Polythene material is high density polyethylene (HDPE), as oil of SPC product 041, Qilu Petrochemical 2480, husky Bick product 6006, Borealis 3490/3440 etc.The cross section of preferred heating wire is rectangle, and the rectangular length of side is 6 ~ 8mm, and wherein, heating wire 1 can be one, also can be many.
When making use, first by the integument 2 of coated for heating wire 1 one deck PE, be processed into the covering thread that electric wire is the same, then according to heavy caliber, the cabling requirement of super large caliber and heating wire clearance distance design the size of welding layer 3, rectangular dimension designs according to the requirement of wiring, multi-size, cabling requirement according to different size bore is determined, such as DN1000mm bore pipe, heating wire diameter 1mm, adjacent heating wire distance is 8mm, so the long L of heating wire cross section rectangle is just designed to 8mm, wide (height) H is just designed to 5mm, utilize Mold Making welding layer 3, machine and cooling forming after, just can be wound in wire plate by the method for winding limit, limit fusion splicing, the temperature 145 ~ 155 DEG C of fusion splicing is advisable, realize two dimension wiring.Adopt the utility model technology, various dimensions wiring can be realized on more complicated physical dimension face.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
