Description
【Technical field】
The present invention relates to a kind of abundant hot-melt adhesive paste pipelines of electromagnetic induction internal-expansion type, belong to pipeline fusion techniques field.
【Background technology】
In the construction of pipeline engineering, the piping network for especially being used to supply water and supply, people use more and more
Using steel pipe as the composite metal-plastic pipe material of base tube, by the connection of pure plastic pipe part electromagnetic welding to shape between steel-plastic composite pipe
At pipeline, steel-plastic composite pipe integrates high pressure resistant, anti-corrosion and resistance oxygen, which is traditional galvanized pipe, thermoplasticity modeling
The upgraded product of expects pipe.
In the prior art, composite metal-plastic pipe material is difficult to really realize forms tightening seal with the internal ring portion of pure plastic pipe part
Welding, inevitably there are welding gaps with the internal ring portion of pure plastic pipe part for composite metal-plastic pipe material, to leak
Phenomenon, and circle situation is lost when pure plastic pipe part exists, welding gap will become much larger.
How composite metal-plastic pipe material and the internal ring portion of pure plastic pipe part between reliable seamless tightening seal welding is promoted,
It is a big technical barrier of pipeline industry in fact, applicant passes through unremitting effort with great concentration, and present application is due to generating.
【Invention content】
Existing deficiency for the above-mentioned prior art, the present invention provide a kind of abundant hot-melt adhesive paste of electromagnetic induction internal-expansion type
Pipeline can form the seamless sealing welding of high reliability between composite metal-plastic pipe material and the internal ring portion of pure plastic pipe part,
The generation of pipe leakage phenomenon is prevented.
For this purpose, the present invention provides the following technical solution：
The abundant hot-melt adhesive paste pipeline of electromagnetic induction internal-expansion type, including pure plastic pipe part and composite metal-plastic pipe material, metal
There is compound plastic pipe inside and outside plastic pipe layer and intermetallic metal tube layer, pure plastic pipe part to have at least one internal ring portion, outer shroud
Portion and annular socket joint chamber, composite metal-plastic pipe material are plugged on annular socket joint intracavitary, and improvement is：Further include rubber sleeve and
Ring bush, ring bush have annular storage tank and two lining oral areas positioned at the annular storage tank two side ends, rubber sleeve set
It is placed in annular storage tank；Ring bush is embedded by the two lining oral areas in pure plastic pipe part, the rubber under being squeezed
Set is then constrained between internal ring portion and annular storage tank；It is soft when composite metal-plastic pipe material is melted with pure plastic pipe part electromagnetism
The internal ring portion of change state bears circumferential squeeze from rubber sleeve and expands to promote pure plastic pipe part and composite metal-plastic pipe material
Form seamless frit seal.
As further supplementing said program and perfect, the invention also includes following technical characteristics：
Before ring bush with annular storage tank is by set body portion, preposition lining oral area, postposition lining oral area and transition connection
It sets lining oral area and is formed with the second conical surface portion that first conical surface portion in set body portion and transition connect postposition lining oral area and cover body portion,
In, the diameter of preposition lining oral area is more than the diameter in set body portion and less than the diameter of postposition lining oral area, set body portion is isodiametric, ring
Shape bushing is frontward installed in preposition lining oral area in pure plastic pipe part, and forward and backward lining oral area of setting is made fully to contradict internal ring portion.
The both sides port of above-mentioned rubber sleeve has horn mouth compatible with the first conical surface portion, the second conical surface portion respectively, rubber
The outer surface of gum cover is in the side shape of round platform.
The external surface shape of internal ring portion its wall surface and rubber sleeve that are in contact with the outer surface of rubber sleeve matches.
The invention has the advantages that and advantageous effect：
When ring bush is not embedded on pure plastic pipe part, rubber sleeve is to be in natural form set not by external force constraint completely
It is placed on ring bush.
During setting ring bush in pure plastic pipe part, it is squeezed deformation along with rubber sleeve and is constrained to
Between the internal ring portion of pure plastic pipe part and the annular storage tank of ring bush.
When having planted composite metal-plastic pipe material together and pure plastic pipe part and having been melted by electromagnetism, soft state it is interior
Ring portion bear from rubber sleeve it is circumferential squeeze expansion, the favourable outcome brought be substantially eliminate internal ring portion, outer portion with
Socket joint gap between composite metal-plastic pipe material, realized 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 significant effect is unique, and welding quality is high, and the fluid in pipeline is close
Envelope property is good, has prevented pipe leakage hidden danger.
In addition, the technical program also can overcome the disadvantages that pure plastic pipe part has the slight circle that loses and (for example aoxidized after manufacture, shipping storage
The defect Deng caused by) in the case of, 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 be more than the diameter in set body portion and
Less than the diameter that postposition serves as a contrast oral area, set body portion equal diameter, and the both sides port of rubber sleeve have respectively with ring bush first
The compatible horn mouth of the second conical surface portion of conical surface portion, ring bush, the outer surface of rubber sleeve are in the side shape of round platform, match cyclization
The unique mounting structure of shape bushing is to be installed in pure plastic pipe part in such a way that preposition lining oral area is facing forward, meets and forward and backward sets lining
Oral area fully contradicts internal ring portion, significantly has the advantage that：Due to being planted to pure plastics together with rubber sleeve in ring bush
When in pipe fitting, wherein extrusion deformation degree maximum is nearby born in the outer end of rubber sleeve, subsequently when internal ring portion and interior plastic pipe layer are soft
When change, then the circumferential extruding dilating effect of this part of rubber sleeve towards corresponding internal ring portion near ports is most strong, this makes
Frit seal effect highest at the near ports of its internal ring portion of pure plastic pipe part, it is meant that substantially increase pure plastic pipe part port
The leakproofness in (leakage starting source) nearby.
