Background technique
The thermofusible spigot Placement is mainly adopted in the connection of the pipe-line system of metallic plastic-lining pipes such as water supply at present,, heating, air feed.Spill one section inner lining plastic tube after at first the outer layer metal of metallic plastic-lining composite pipe being peeled off, use special tool to carry out respectively carrying out the socket joint welding again behind the surface melting with inwall then with the plastic pipe of material.Become the lateral extrusion state along pipe fitting when tubing is connected with pipe fitting, form, produce the welding density of fused body along pipe fitting fusion face pressure radially; Thereby ensure certain heat seal strength and welding density, be referred to as the socket joint welding of interference usually, when the pipe fitting hot melt connects; Axial direction along pipe fitting must form the socket joint accumulation body, can cause pipe fitting undergauge even blocking pipe, produces potential safety hazard; Because metallic plastic-lining meets in the pipeline, and outer field metallic conduit is different with the linear expansion coeffcient of plastic lining pipeline, the linear expansion amount of plastics is bigger in addition; With the aluminum alloy is example, approximately is 7 times of aluminum alloy, thereby when causing expanding with heat and contract with cold in temperature variation; Two ends at the metallic plastic-lining multiple tube; Be pipeline and pipe fitting joint, the plastic lining pipeline has one section expansion elongation and exposes outside metallic conduit, and metallic conduit can't wrap up it fully, cover.Aspect the structural strength and compressive strength of whole tubing, the exposed plastic lining pipeline of elongation has formed the weak section of metallic plastic-lining multiple tube system, occurs water clock the most easily in this weakness section, even pipe explosion accident.Therefore caused rigidity, the compressive strength of metallic plastic-lining multiple tube system also to reduce to the level with plastic lining pipeline system; The overall structure rigidity and the compressive strength advantage of metal piping system will not exist, and become the systematic defect of metallic plastic-lining pipeline.
Summary of the invention
Problem to above-mentioned existing technology existence; The utility model provides a kind of novel anti-undergauge pipe fitting, can effectively prevent undergauge and line clogging phenomenon, has improved the fusion intensity and fusion sealing of connection part; And improved the integral rigidity that pipeline connects, very practical.
The technological scheme of the utility model is: a kind of novel anti-undergauge pipe fitting; Comprise hollow, open-ended main pipe body; Said main pipe body inwall comprises the linkage section at middle part, near the inserting section of end, and the accumulation section between linkage section and the inserting section, the external diameter coupling of the diameter of inserting section and corresponding bell-and-spigot pipe internal lining pipe; Pile up the internal diameter coupling of diameter with the corresponding bell-and-spigot pipe internal lining pipe of section, the diameter of linkage section is less than the diameter of piling up section.
As preferably, the horn mouth that increases gradually to outer diameter in the opening end of inserting section is served as reasons, the diameter of horn mouth largest portion is greater than the external diameter of corresponding bell-and-spigot pipe outer tube.
As preferably, the main pipe body outer wall has annular groove, is provided with stiffening rib in the annular groove.
As preferably, the material of said main pipe body is atactic copolymerized polypropene, polybutylene or heat-proof polythene.
As preferably, said main pipe body is straight-through tube, swan neck, three-way pipe or four-way pipe.
As preferably, said straight-through tube comprises equal coupling pipe, reducing coupling pipe, internal thread straight-through tube and outer silk straight-through tube.
As preferably, said swan neck comprises 90 degree elbows, one eighth bend, internal thread elbow and outer silk elbow.
As preferably, said three-way pipe comprises straight tee and reduced tee.
As preferably, said four-way pipe comprises straight cross pipe and reducing cross.
The beneficial effect of the utility model is: the space that forms because of diameter difference between the accumulation section of the utility model main pipe body inwall and the linkage section can hold the socket joint accumulation body that when fusion forms along the axial direction of pipe fitting; Be formed with the confined space that press seal closes; Avoid undergauge and blocking phenomenon, improved sealability.And because the void ratio of piling up between section and the linkage section is less, most of socket joint accumulation body is pressed fusion by envelope in this space, has improved the fusion intensity of connection part.The expansion extension that produces when the horn mouth of the opening end of inserting section is can be with the pipeline medium temperature variation big places in it, has avoided the plastic lining pipeline to expose outside metallic conduit, has improved integral rigidity and compressive strength that pipeline connects, and is very practical.
