Description
Technical field
The utility model relates to plastic pipe or plastic composition pipeline, particularly plastic pipe or composite pipe joint of plastic technical field.
Background technique
Present plastic pipe or the Placement between the plastic composition pipeline mostly are direct welding, perhaps connect by the live metal flange behind the welded flange root, perhaps directly connect by the live metal flange behind the flange.Its shortcoming is that the pipeline maintainance of directly welding is changed difficulty; Connect latter linked pipeline with the flange root bead, Environmental Conditions is restricted, and uses at floating on water, easily fracture; Cost is high; Because the flange root that welds is injection moulding production, but not the extrusion molding production of pipeline is not wear-resistant.The direct latter linked pipeline of flange, because flange wants the line up heating to process by flange, so in heating process, molecular weight generation physical change in the section of tubing of heating, overall performance descend obviously, be subjected to external impacts after, easily fracture, large diameter pipeline adopts this method to connect, and the danger of broken end is large.
In addition, researched and developed the blind joint with mother-son mouth metal lining ring of a kind of plastic pipe or plastic composition pipeline before the inventor of this patent, and realized the seamless link of plastic pipe, this adapter body part comprises pipeline body 1 as shown in Figure 1; The pipeline body two ends are provided with horn mouth 6; Horn mouth is provided with the metallic sheath with the suitable angle of horn mouth outer wall outward; The metallic sheath inboard is provided with loose flange, and the internal diameter of loose flange is less than metallic sheath; Also be provided with the metal lining ring with mother-son mouth in the horn mouth; Metal liner circle mouth 1a is with fluted; Be provided with O type circle 1c in the groove; Metal lining ring female mouthful of 1b and the corresponding setting of metal liner circle mouth 1a.The combination that the metal lining ring of this kind connector by using band mother-son mouth and loose flange are realized two pipelines, but because the joint is the metal lining ring, easily by the flow-induced corrosion in the pipe, and along with the corrosion sealing of metal lining ring can variation.
The model utility content
In order to solve the above-mentioned problem that joint is not corrosion-resistant and sealing is not high with mother-son mouth metal lining ring, the utility model proposes the blind joint that is provided with the line with rubber layer on a kind of improved metal lining ring, realized equally that not only the inside and outside all no-welding-seams of pipeline body connect, and structure is more simple and firm, better tightness, more corrosion-resistant, and install and use more convenient.
The technical solution of the utility model is achieved in that
A kind of blind joint of belt material glue-line, its agent structure comprises pipeline body, loose flange, fixing bolt, nut; The two ends of described pipeline body are provided with horn mouth; Described loose flange is sleeved on the outer wall of described pipeline body; The internal diameter of described loose flange is less than bell-mouthed diameter; Described horn mouth inboard is provided with the metal lining ring; Described metal lining ring and described horn mouth are suitable; The inwall of described metal lining ring and front end face are provided with the line with rubber layer.
As to a kind of improvement of the present utility model, the front end face of described metal lining ring and described bell-mouthed front end face are at grade; The line with rubber layer of described metal lining ring front end face is outstanding to be arranged on the metal lining ring; The internal diameter of described metal lining ring is greater than the internal diameter of described pipeline body; And the internal diameter of the line with rubber layer of described metal lining ring inwall is identical with the internal diameter of described pipeline body, and namely the inwall of the line with rubber layer of described metal lining ring inwall and described pipeline body is on same cylinder plane.
As further improving of the present utility model, this blind joint also comprises seal rubber pad, and described seal rubber pad is provided with the bolt hole suitable with described loose flange; The internal diameter of described seal rubber pad is identical with the internal diameter of pipeline body.
Further improve as of the present utility model, the surface of contact of described loose flange and pipeline body and described horn mouth outer wall are suitable again.Like this, when two pipelines connect, loose flange and horn mouth outer wall chimeric more closely, firmly.
As a kind of optimal way of the present utility model, described metal lining ring adopts steel ring as this.
When two pipelines of the utility model connect, be connected and fixed two loose flanges on the joint by bolt and nut, realize sealing by the line with rubber layer that metal lining ring front end face is provided with.When being provided with seal rubber pad, the line with rubber layer of a pipe coupling interconnects by the line with rubber layer of seal rubber pad and another pipe coupling, has realized better sealing effect.
In sum, do not need to be provided with metallic sheath on the blind joint horn mouth outer wall of the present utility model, structure is simpler again.
Because metal lining ring front end face is provided with the line with rubber layer, describedly do not need to arrange again O type circle not need to be provided with again mother-son mouth yet, just can be tightly connected by line with rubber layer and seal rubber pad realization, simplified the processing technology of metal lining ring.
And, because the inwall of described metal lining ring and front end face all are provided with the line with rubber layer, so when fluid passed through, the line with rubber layer can protect the metal lining ring not to be subjected to flow-induced corrosion, so that this joint is more corrosion-resistant, wear-resistant.
As above, this joint structure is simple, easy to connect; Environmental Conditions is unrestricted; The joint no-welding-seam; Corrosion-resistant, wear-resistant; High pressure and low-pressure pipeline all can use.
