Problems solved by technology
From this, it can be seen that the sealing qualification rate of the existing sealing structure cannot meet the demand, and as the operating pressure increases, the rejection rate increases rapidly
Moreover, under normal pressure, the pass rate cannot satisfy the manufacturer

The invention relates to a clamping sleeve type connector flexible sealing structure, which at least comprises a clamping sleeve type connector body (1), a nut (2), a tubular body (3), a clamping sleeve (4) and a seal ring (5). The clamping sleeve type connector body (1) is provided with a clamping sleeve type connector body inner conical surface (6) and an external thread (8); the nut (2) is provided with an internal thread (7); the outer wall of one end of the tubular body (3) is fixedly connected with the clamping sleeve (4); the seal ring (5) sleeves the outer wall of one end of the tubular body (3) and contacts the clamping sleeve (4); the other end of the tubular body (3) penetrates through the nut (2) so as to be exposed outside; the seal ring (5) adapts to the clamping sleeve type connector body inner conical surface (6); the internal thread (7) and the external thread (8) are matched. The product can effectively prevent the occurrence of the phenomena of three leakage (oil leakage, air leakage and water leakage), and meanwhile, has the characteristics of low processing difficulty, quality stability, and convenience in batch production.
Description
technical field [0001] The invention relates to a ferrule-type joint flexible sealing structure, which belongs to the technical field of ferrule-type joint flexible sealing structure products. Background technique [0002] At present, the flexible sealing structure of motor vehicle ferrule joint is usually composed of ferrule joint body, ferrule, nut and pipe body (refer to GB / T3764-2008 ferrule). As for the ferrule, the key part of the seal, metal parts are usually used as the material, and the processing accuracy is also high, and when it is fixedly connected with the pipe fitting, the necking method is used to force the end of the ferrule to deform and fix it with the pipe body; because the ferrule is deformed during the deformation process It will cause irregular deformation on the sealing surface of the product, thereby reducing the sealing performance, and easily causing three leakages (oil leakage, air leakage, water leakage) phenomenon. In severe cases, it will caus...
