Abstract
The utility model relates to a connecting assembly for large-caliber polymer pipes, in particular to a pipe joint with easy assembling and disassembling exclusively for high-density polyethylene plastic pipe connection. A cavity with wide opening is arranged on one end of a continuous pipe body, a cavity with narrow opening is arranged on one side in correspondence with the pipe with wide opening, and a fixing snap ring device is arranged between the cavity with wide opening and the cavity with narrow opening. The utility model has the advantages of high rate of finished products of tube, little material waste, high strength of joint, lower consumption of material, smaller amount of site operation workload as well as easy assembly.
Description
Technical field
The utility model relates to a kind of connection part of heavy caliber polymer pipe, especially relates to a kind of pipe coupling that is exclusively used in the easy disassembly of pipeline connections such as high-density polyethylene plastics.
Background technique
Point out in the polyethylene double-wall corrugated pipe material GB/T194721-2004 GB: the spendable elastic seal ring Placement of tubing has: socket joint connects; Pipe fitting connects; Hough is solidly connected outward etc.These three kinds of Placements all have shortcoming in various degree.
The socket joint Placement: require every fixed length tubing must be with a socket joint enlarging, scrap if whole Zhi Guancai goes up then whole of somewhere defectiveness, so product percent of pass is low, waste material is many.Secondly, duct length changes unpredictably in the engineering, often wants incising pipes, part tubing can't be utilized and scraps; Its three, the bellmouth stiffness and strength is low, and damage shortcoming such as break is often arranged.
Pipe fitting Placement: adopt two ends all with the real wall muff joint of elastic seal ring.It compares poor rigidity with the riffled tube muff joint, consumptive material is many; Secondly, this joint is wanted independent supporting transporting, and is on-the-spot supporting, and the elastic seal ring at dress two ends, construction amount increase and be inconvenient.
The Hough mode of being solidly connected outward has many deficiencies, the actual use seldom.
Summary of the invention
It is low that the utility model is primarily aimed at existing in prior technology tubing yield rate, waste material is many, bellmouth, sleeve poor rigidity, consumptive material is more, the site operation amount is big, technical problems such as inconvenience are installed, the pipe coupling of a kind of tubing yield rate height, waste material is few, joint strength is high, materials consumption is less, the site operation amount is less, easy for installation easy disassembly is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: pipe coupling one end is provided with wide oral cavity body, be provided with the slot cavity with the corresponding side of wide oral cavity body, between wide oral cavity body and slot cavity, be provided with the location card loop device.Plastic tube inserts from the both sides cavity,, is played transition and connects seal action to spacing by the location card annulate shaft, can be according to the pipe coupling of different plastic tubes and size needs production different size size.
As preferably, described location card loop device ties up between wide oral cavity body and the slot cavity, the inwall of body is provided with a circular snap ring sheet continuously.The location card ring structure ties up to big small aperture spaced-apart locations, plays pipes at two ends and inserts the axial limiting effect.
As preferably, the inwall aperture of described clasp piece is less than the inner diameter of slot cavity.The location card annular aperture is greater than the external diameter that inserts tubing trough (lamination), and its side has and the identical gradient in tubing crest (or muscle) side, and tubing inserts the trailing flank tight connecting, improves adhesive strength and Watertightness.
As preferably, the inner diameter of described wide oral cavity body is greater than the inner diameter of slot cavity.Tubing is packed into before the body of wide oral cavity, elastic seal ring is set in the trough groove of bellows (riffled tube), and elastic packing encloses fastening and seal action in the tubing patchhole; And joint sealant has been adopted before bringing out factory in small aperture one, be installed on the tubing tightly, but pipe coupling and tubing constitutes the one whole Transporting, deposits conveniently, saves again on-the-spot installation amount.
As preferably, described continuous tube wall is provided with some stiffening ribs.Improve the rigidity of pipe coupling and saved the material consumption.
As preferably, described continuous body adopts high-density polyethylene material to make.Preferably adopt the material that material is consistent or linear expansion coeffcient is close with tubing, can improve gluing reliability.
Therefore, the utlity model has characteristics such as tubing yield rate height, waste material is few, joint strength is high, materials consumption is less, the site operation amount is less, easy for installation; Especially tubing yield rate height, joint strength height, easy for installation.
Description of drawings
Accompanying drawing 1 is a kind of structural perspective of the present utility model.
Accompanying drawing 2 is a kind of structural representations of the present utility model.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1:
Adopt the high-density polyethylene plastics material to make pipe coupling, pipe coupling one end is provided with wide oral cavity body 1, is provided with slot cavity 2 with the wide oral cavity corresponding opposite side of body, and the inner diameter of wide oral cavity body is greater than the inner diameter of slot cavity.The inwall at pipe joint place is provided with a circular snap ring sheet 3 between wide oral cavity body and the slot cavity.Inwall radius and its exterior radius of clasp piece have certain altitude poor.The pipe coupling outer wall is provided with some stiffening ribs 4.
When installing and using, tubing is packed into before the body of wide oral cavity, elastic seal ring is set in the trough groove of bellows (riffled tube), and elastic packing encloses fastening and seal action in the tubing patchhole; And joint sealant has been adopted before bringing out factory in small aperture one, be installed on the tubing tightly, but pipe coupling and tubing constitutes the one whole Transporting, deposits conveniently, saves again on-the-spot installation amount.
