Description
[technical field]
The present invention relates to a kind of electromagnetic induction internal-expansion type abundant hot-melt adhesive paste pipeline, belong to pipeline fusion techniques field.
[background technology]
In the construction of pipeline engineering, especially for supplying water and the piping network of supply, people are increasingly using
Composite metal-plastic pipe material with steel pipe as base tube, is connected thus shape by pure plastic pipe part electromagnetic welding between steel-plastic composite pipe
Becoming pipeline, steel-plastic composite pipe integrates high pressure resistant, anticorrosion and resistance oxygen, and this emerging tubing is that traditional galvanized pipe, thermoplasticity are moulded
The upgraded product of material pipe.
In prior art, composite metal-plastic pipe material is difficult to the internal ring portion really realized with pure plastic pipe part and forms tightening seal
Welding, there is welding gap, thus seepage occurs in composite metal-plastic pipe material inevitably internal ring portion with pure plastic pipe part
Phenomenon, and when pure plastic pipe part exists circle situation of losing, and welding gap will become much larger.
How to promote reliable seamless tightening seal welding between the internal ring portion of composite metal-plastic pipe material and pure plastic pipe part,
Being a big technical barrier of pipeline industry in fact, applicant is through unremitting effort with great concentration, and subject application is owing to producing.
[summary of the invention]
For the deficiency existing for above-mentioned prior art, the present invention provides a kind of abundant hot-melt adhesive paste of electromagnetic induction internal-expansion type
Pipeline, can form high reliability seamless sealing welding between its composite metal-plastic pipe material and internal ring portion of pure plastic pipe part,
Stop the generation of pipe leakage phenomenon.
To this end, the present invention provides following technical scheme:
Electromagnetic induction internal-expansion type abundant hot-melt adhesive paste pipeline, including pure plastic pipe part and composite metal-plastic pipe material, metal
Compound plastic pipe has inside and outside plastic pipe layer and intermetallic metal tube layer, and pure plastic pipe part has at least one internal ring portion, outer shroud
Portion and annular socket joint chamber, composite metal-plastic pipe material be plugged on annular socket joint intracavity, its improvement is: also include rubber sleeve and
Ring bush, ring bush has annular storage tank and is positioned at two lining oral areas of this annular storage tank two side ends, rubber sleeve set
It is placed in annular storage tank；Ring bush is embedded in pure plastic pipe part by the two lining oral area, the rubber under being squeezed
Set is then restrained between internal ring portion and annular storage tank；When composite metal-plastic pipe material and pure plastic pipe part electromagnetism melt, soft
The circumference extruding that the internal ring portion of change state bears from rubber sleeve is expanded to promote pure plastic pipe part and composite metal-plastic pipe material
Form seamless frit seal.
Supplement further and perfect as to such scheme, present invention additionally comprises following technical characteristic:
There is the ring bush of annular storage tank by overlapping before body portion, preposition lining oral area, rearmounted lining oral area and transition connect
Put lining oral area and be connected rearmounted lining oral area and the second conical surface portion composition overlapping body portion with the first conical surface portion and the transition in set body portion, its
In, the diameter of the preposition lining oral area diameter more than set body portion and the diameter less than rearmounted lining oral area, set body portion is isodiametric, ring
Shape lining is installed in pure plastic pipe part frontward with preposition lining oral area, and makes forward and backward lining oral area of putting the most fully conflict internal ring portion.
The both sides port of above-mentioned rubber sleeve has horn mouth suitable with the first conical surface portion, the second conical surface portion respectively, rubber
The outer surface of gum cover is the side shape of round platform.
Its wall surface contacted with the outer surface of rubber sleeve of internal ring portion matches with the external surface shape of rubber sleeve.
The invention have the advantages that and beneficial effect:
When ring bush is not embedded on pure plastic pipe part, rubber sleeve be the most not by external force constraint in natural form set
It is placed on ring bush.
During setting ring bush in pure plastic pipe part, it is squeezed along with rubber sleeve and deforms and be restrained to
Between internal ring portion and the annular storage tank of ring bush of pure plastic pipe part.
When being plugged on composite metal-plastic pipe material together and pure plastic pipe part and being melted by electromagnetism, soft state interior
Ring portion bear from rubber sleeve circumference extruding expansion, its favourable outcome brought be substantially eliminate internal ring portion, outer portion with
Socket joint gap between composite metal-plastic pipe material, achieve after cooling composite metal-plastic pipe material with pure plastic pipe part is seamless can
By sealing, present inventive concept is ingenious, and pipe electromagnetic frit seal effect is unique, and welding quality is high, and the fluid in pipeline is close
Envelope property is good, has stopped pipe leakage hidden danger.
It addition, the technical program also can overcome the disadvantages that pure plastic pipe part exists slightly loses circle (such as manufacture, shipping storage rear oxidation
Defect etc. causing) in the case of, it is to avoid the generation in pipeline welding gap.
Variable-diameter structure is designed to the ring bush of unique style: the diameter of preposition lining oral area more than set body portion diameter and
Less than the diameter of rearmounted lining oral area, set body portion equal diameter, and the both sides port of rubber sleeve have respectively with the first of ring bush
Conical surface portion, the suitable horn mouth in the second conical surface portion of ring bush, the outer surface of rubber sleeve is the side shape of round platform, coordinates ring
The mounting structure that shape lining is unique, is i.e. to be installed in pure plastic pipe part in preposition lining oral area mode forward, meets and forward and backward puts lining
Oral area is the most fully conflicted internal ring portion, and it significantly has the advantage that: owing to planting pure plastics together with rubber sleeve at ring bush
Time in pipe fitting, wherein, bear extrusion deformation degree near the outer end of rubber sleeve maximum, follow-up when internal ring portion and interior plastic pipe layer soft
During change, then this part of rubber sleeve is the strongest towards the circumference extruding dilating effect of corresponding internal ring portion near ports, and this makes
At the near ports of pure plastic pipe its internal ring portion of part, frit seal effect is the highest, it is meant that substantially increase pure plastic pipe part port
The sealing of neighbouring (seepage initiates source).
