Embodiment
Pipeline of the present utility model is colded pressing and is sealed strong jointing, connect lining 1 in including and with being used for pipeline is connected to the interior connecting ring 2 that is connected on lining 1 outer surface, in connect lining 1 and can be single-ended, straight-through, reducing butt joint, threeway, four-way, be connected the form of using always with pipeline such as flange, the number of corresponding connecting ring 2 is also along with variation, and what show among Fig. 1 is to have two connection mouths columniform.When using, select for use the external diameter of outer surface to be not less than the interior connection lining 1 of the internal diameter that will carry out connecting tube, could guarantee sealing like this.And the pipeline that will connect can carry out the enlarging operation according to the method for routine earlier before using.The utility model internally connects the structure and connecting ring 2(Fig. 2 of lining 1 outer surface) structure of internal surface cooperates, can make pipeline be connected the outer surface of lining 1 and cooperation took place to melt the internal surface of connecting ring 2 with interior, thereby guarantee the soundness and the sealing that connect.
Fig. 3 shows a kind of interior axial sectional view that connects lining 1 concrete structure of the present utility model, on the progress path of connecting ring 2, namely sealing surface 3, connecting ring non-return face 4 and the connecting ring that has external diameter to increase successively on axially ends into boss 5 at the outer surface of interior connection lining 1; Wherein the external diameter of connecting ring non-return face 4 is not less than the maximum inner diameter of connecting ring 2 internal surfaces; Connecting ring ends the external diameter of boss 5 into greater than the maximum inner diameter of connecting ring 2 internal surfaces.And sealing surface 3 includes the mistake that is no less than and melts fitting surface 31 and be no less than one non-return boss 32; Melt fitting surface 31 and have thread groove or parallel groove crossing, like this when pipeline 7 under the effect of connecting ring inner surface structure, melt fitting surface 31 and took place to melt and cooperate with crossing, thereby guaranteed sealing; And non-return boss 32 is used for increasing the soundness of connection.And, near connecting ring non-return face 4 places the concave surface of melting 33 was arranged at non-return concave station 32.Such structure setting can guarantee that the pipeline that is connected melts fitting surface 31 and obviously compression takes place at non-return boss 32 places crossing, and formation took place to melt seals with the interior lining 1 that is connected; And, in that melting concave surface 33 can guarantee to have certain thickness again excessively, make the pipeline that is connected be difficult to come off from interior connection lining 1, guaranteed the soundness that connects.
In addition, connecting ring non-return face 4 on interior connection lining 1 outer surface and connecting ring end into extension concave surface 6 between the boss 5, after connecting ring 2 is crossed connecting ring non-return face 4 under external force, after the internal surface of connecting ring 2 (together with the part of pipeline) took place to melt with connecting ring non-return face 4, recharge into extension concave surface 6, thereby make connecting ring 2 be difficult to split away off from interior connection lining 1.
The internal surface of connecting ring 2 of the present utility model has the structure that matches with the interior structure that is connected the outer surface of lining 1.Wherein the internal diameter of internal surface diminishes gradually from guide surface 21 to propelling stress surface 22.When using, earlier connecting ring 2 is inserted in pipeline, connect the outer surface (Fig. 4) of lining 1 in wherein guide surface 21 is inserted in earlier as front end.
In the internal surface of connecting ring 2, to advancing stress surface 22, be provided with non-return convex surface 23, compressing surface 24 and retaining face 25 from guide surface 21 successively; The compressing surface 24 that is no less than two is wherein arranged in the internal surface of connecting ring 2, and between compressing surface 24 and non-return convex surface 23, compressing surface 24 and the retaining face 25 face of melting 26 was arranged.The internal diameter of non-return convex surface 23 connects the external diameter (Fig. 5) of the connecting ring non-return face of lining 1 greater than the external diameter of the sealing surface 3 of interior connection lining 1 in being less than or equal to.
In the time of fixing tube, because the internal diameter of non-return convex surface 23 greater than the external diameter of the sealing surface 3 of interior connection lining 1, connects the external diameter of the connecting ring non-return face of lining 1 in being less than or equal to; Therefore, under external force, non-return convex surface 23 can arrive connecting ring non-return face 4 places under the situation of melting with the very little mistake of pipeline 7 occurrence degrees, but because the internal diameter of non-return convex surface 23 is less than the external diameter of connecting ring non-return face 4, this just needs bigger active force to act on the propelling stress surface 22, make non-return convex surface 23 after taking place to melt with connecting ring non-return face 4, entered again and melt in the groove 33 (Fig. 6).Fig. 7 shows that connecting ring 2 is crossed and circulated connecting ring non-return face 4 and be packed into structure in the extension concave surface.
And at connecting ring 2 during along the axial advancement of interior connection lining 1, because diminishing suddenly of internal diameter, compressing surface 24 can produce one to pipeline 7 and press down, making pipeline 7 melt fitting surface 31 in the mistake of interior connection lining 1 produced and melted, simultaneously, the upper surface of pipeline also melts face 26 with the mistake of the internal surface of connecting ring and took place to melt.And, because the compressing surface 24 that exists a plurality of internal diameters to diminish gradually, and each compressing surface 24 all can make pipeline and the interior mistake that is connected the surface of lining 1 and connecting ring 2 melt the degree increase, thus pipeline connection stability and sealing increased.
A kind of concrete size to jointing of the present utility model is described in detail below:
The external diameter that the mistake that connects lining 1 is wherein melted fitting surface 31 is 12.04mm, the external diameter of non-return boss 32 is 12.30mm, crossing the external diameter that melts groove 33 is 12.10mm, the external diameter of connecting ring non-return face 4 is that the external diameter of 14.50mm, extension concave surface 6 is 14.40mm, and the external diameter of boss is 15.30mm and connecting ring ends into.On width, the outermost end from non-return boss 32 to interior connection lining 1 is 6.8mm, and the width from non-return boss 32 to connecting ring non-return face 4 is 1.9mm, and the width of extension concave surface 6 is 0.8mm.
Corresponding with interior connection lining 1, the entire length of connecting ring 2 (from guide surface 21 to advancing stress surface 22) is 10mm, and its whole external diameter is 19.6mm.Aspect internal diameter, the internal diameter of non-return convex surface 23 is 14.46mm, and the internal diameter of compressing surface 24 is 14mm, and the internal diameter of retaining face 25 is 13.70mm.
For the interior size that connects lining 1 and connecting ring 2 in the utility model joint, those skilled in the art can specifically select in the technical solution of the utility model, and is not limited to above-mentioned concrete record.
For related position in interior connection lining 1 and the connecting ring 2, the function that Ying Yiqi describes in specification is as restriction, and is not subjected to the restriction of the used concrete noun of the utility model, and those skilled in the art also can select for use other noun to describe.
