Description
[technical field]
The present invention relates to a kind of pipeline butt joint connects; Specifically be meant the mouth of pipe over against the straight tube welding become pipeline; Be applicable between the pure plastic straighttube, between the steel band reinforced spiral ripple straight tube, steel wire mesh frame strengthens the welding between the compound straight tube, belongs to pipeline butt joint interconnection technique field.
[background technique]
Existing pipeline; Especially large diameter pipeline; For example the giving of usefulness such as municipal engineering, hydraulic engineering, drainage pipe, straight tube generally has following several kinds with linkage structure between the straight tube: rubber seal bayonet joint, clip connected, resistance wire hot melt band are connected etc.More than several kinds of some defectives of pipe connecting structure existence in various degree: rubber seal bayonet joint structure need be processed into bell and spigot joint with the mouth of pipe; Accepting the groove that the interface domestic demand is processed with the installation of confession rubber seal; Process structure is complicated; And receive the restriction ratio of rubber seal more, such as rubber seal life-span weak point, and the socket joint join strength is low; The clip connected structure is to adopt rubber-coated cover of clip and foaming offset plate, influenced greatly by geology, and pipeline junction disconnects in the geology change easily, influences the long-term working life of pipe-line system; The structure of resistance wire hot melt band is in the plastic based band, to be distributed into the wall scroll resistance wire; This wall scroll resistance wire winding form is the positive and negative coherent shape of " U " font, for preventing the resistance wire short circuit, needs certain silk spacer; When pipeline construction connects; Joint at two straight tubes twines coating resistance wire hot melt band, through to the resistance wire heating, can make two molten butt joints of straight tubes realization electric heating then.Because the existence of silk spacer is difficult to accomplish homogeneous heating, the intensity of weld is relatively low, and for making the plastics fusion; Need high electric current, power consumption is bigger, has increased the pipeline link cost; And when mouth of pipe molten state, resistance wire blows resistance wire because of displacement easily, and resistance wire is persistent fever no longer just; Not only resistance wire hot melt band is scrapped thereupon, and influences the welding process, mends welding and then possibly form potential hidden leakage defect.
In view of this, existing pipeline docking technique has the necessity of improvement in fact.
[summary of the invention]
The problem that the present invention will solve be the deficiency that exists to above-mentioned existing technology and provide a kind of heat seal strength high, have good Butt sealing property, the molten docking structure pipeline of electromagnetism that the consumption reduction welding cost that can economize on electricity again is low.
For solving the problems of the technologies described above, the present invention provides following technological scheme:
The pipeline of the molten docking structure of electromagnetism; Comprise first straight tube, second straight tube and hot melt band; First straight tube and second straight tube are the mouth of pipe and contact setting over against, mouth of pipe end face; The hot melt band coats the Butt Section outer peripheral surface of first straight tube and second straight tube, and this Butt Section is that pure plastics or its skin are plastic layers, and its improvements are: the said hot melt band that is coated state is the molten composite steel-plastic belt of electromagnetism; The molten composite steel-plastic belt structure of this electromagnetism is by plastic surface layer, hole pattern steel layer and the plastics nexine is compound constitutes; Its length of run is greater than said Butt Section excircle length, and when molten composite steel-plastic belt outer shroud week of the electromagnetism of coated state formed alternating magnetic field, its plastics nexine was connected with Butt Section outer peripheral surface hot melt.
It is evenly distributed that the eyelet of above-mentioned hole pattern steel layer is the plum blossom shape.
The molten composite steel-plastic belt of electromagnetism has hole pattern steel layer in its plastic body interplantation; Helping in extruding the machine shaping process plastic surface layer and plastics nexine all realizes interpenetrating bonding through mesh; So that organically combining, the molten composite steel-plastic belt of electromagnetism becomes a single piece; Thereby realized hole pattern steel layer well compound with plastic surface layer, plastics nexine and plastic surface layer and plastics nexine respectively; Especially it is evenly distributed that the eyelet of hole pattern steel layer is the plum blossom shape, improved the overall construction intensity of the molten composite steel-plastic belt of electromagnetism.
Above-mentioned first straight tube, second straight tube are pure plastic straighttube.
Above-mentioned first straight tube, second straight tube are the steel band reinforced spiral ripple straight tube, and the Butt Section of two pipes is pure plastic.
Above-mentioned first straight tube, second straight tube are steel wire mesh frame and strengthen compound straight tube.
Compared with prior art, the present invention has following advantage and beneficial effect:
The molten composite steel-plastic belt of the electromagnetism that the coating form occurs is issued to the rapidly uniform purpose of heating in the effect of alternating magnetic field in a creative way; Thoroughly straight tube butt joint conventional art has been answered on the top, in case make win straight tube and the Butt Section electromagnetism of second straight tube melt mode dock just can form have good seal performance, pipeline that heat seal strength is high, this pipeline is durable in use; Straight tube butt joint is easy to implement, quickness and high efficiency, economize on electricity consumption reduction welding cost are low; Straight tube structure is simple, need not enlarging processing, need not to be provided with interface, birdsmouth; Need not to be provided with seal ring in the mouth of pipe, also no longer go out phenomenon and adopt resistance wire hot melt band that resistance wire takes place in fusion process to blow phenomenon.
