Abstract
The utility model relates to a bendable high pressure joint, which comprises a drum-shaped multilayer spreading cord fabric framework (5) and molded radial multilayer spreading cord fabric flanges (3) are the both ends of the framework (5), inside which a fastening flange (1) is arranged. An elastic layer, which is closely fitted with the rind of the flange (1) and is in corresponding with a fastening hole (6), is coated at the external layer of the flange (3). The utility model has simple structure, great sealing performance and uneasy shedding.
Description
Technical field
The utility model relates to a kind of high pressure joint.
Background technique
In pipeline construction, must install one at a certain distance and be called pipe coupling or be called the device that pipeline connects expansion bend.It is that 9321 1315.X, name are called the utility model patent of " elastic force pipeline stretch vibration damper " that China's Patent Gazette for Utility Models discloses a kind of patent No..This utility model patent is made up of the flexible skeleton of the cydariform of multilayer frictioning curtain layer, the rubber seal of skeleton two ends mold pressing and the flange of seal ring inboard, wherein flange and seal ring, are found along fastening assembling mutually in actual use by the convex annular on annular groove on the flange exterior edge face and the corresponding with it seal ring interior edge face.This utility model patent has certain defective: at first, the radial dimension of seal ring is little. and make the sealing surface in the pipeline connection correspondingly also less, cause sealing effect not satisfactory; Secondly, owing to fasten mount mutually by annular groove and convex annular edge between flange and the seal ring, in the pipeline using process.When manifold pressure was higher, sealing caused pipeline to reveal along taking off from flange.
At above-mentioned the deficiencies in the prior art.The purpose of this utility model is to provide a kind of flexible high pressure joint. with the rubber body that prevents joint and the disengaging of flange.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of flexible high pressure joint and has solved the defective that the prior art middle joint is left out easily.
Technological scheme
The utility model provides a kind of flexible high pressure joint, comprise that the cydariform multilayer scrapes the radially multilayer of rubberized cord skeleton 5 and its two ends mold pressing and scrape rubberized cord flange 3, the inboard of flange 3 is equipped with clamp flange 1, it is characterized in that: described flange 3 outer, fastener hole 6 mutual correspondences identical mutually with one deck elasitic layer and clamp flange 1 radial dimension.
Be provided with potted line 7 on the exterior edge face of described flange 3 around the center hole.
Beneficial effect
To be pressed into the radial dimension of the radial dimension of rubber flange of one and fastening flange consistent owing to scrape rubberized cord cydariform skeleton pattern with multilayer, increased the sealing surface after joint and pipeline are fastenedly connected greatly, strengthened the sealability of joint; 2, because flange is corresponding with the fastener hole of fastening flange, and fastening screw passed two flanges simultaneously when joint was connected with pipeline, so just prevented flange inside slippage when the pipeline inner high voltage is worked, stopped the leakage of pipe coupling.

Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiments only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiment 1
A kind of flexible high pressure joint comprises that the cydariform multilayer scrapes the two ends mold pressing of rubberized cord skeleton 5 and have multilayer to scrape rubberized cord rubber flange 3, scribbles built-in glue 4 and outer attached glue 2 at the inner and outer surface of skeleton 5, in the inboard of rubber flange 3 a steel clamp flange 1 is arranged respectively.The radial dimension of clamp flange 1 and rubber flange 3 coincide mutually, and fastener hole 6 is corresponding mutually.In addition, around the center hole of rubber flange 3, be provided with potted line 7, to strengthen sealing effect.
Claims (2)
1. flexible high pressure joint, comprise that the cydariform multilayer scrapes the radially multilayer of rubberized cord skeleton (5) and its two ends mold pressing and scrape rubberized cord flange (3), the inboard of flange (3) is equipped with clamp flange (1), it is characterized in that: outer, fastener hole (6) the mutual correspondence identical mutually with one deck elasitic layer and clamp flange (1) radial dimension of described flange (3).
2. flexible high pressure joint according to claim 1 is characterized in that: be provided with potted line (7) on the exterior edge face of described flange (3) around the center hole.
