Detailed
Because the hardness of the joint body after heat treatment is not enough, the cone surface in the joint body will be damaged after several times of removal, which will affect the sealing performance.The connecting screws of the main body of the joint and the screw threads of foshan stainless steel hydraulic joint nut are all ordinary fine thread with low precision.After several times of desorption, the connecting bolt and nut of the main body of the joint will be deformed, and the connecting bolt and nut will be disused.1.3.3 high requirements for assembly, high requirements for assembly skills, special special boxes are required, and poor assembly consistency.All types of stainless steel rapid joints due to the ferrule deformation, must be cut on the surface of the steel tube to a certain depth, so requires considerable assembly torque, and joint main body hardness is generally not high, this is in order to avoid damage during assembly joint conical body, therefore, when the ring assembly, in advance through a dedicated pre-tightening device fixed (mechanical or manual).Assembly parts.These quality depends on the ferrule bag manufacturing quality and technology of assembly workers, impact resistance and low oscillation of 1.4 stainless steel fittings pipe fittings of stainless steel tube joint is wiped, nanjing connection pipe joint body of the screw and nut adopt ordinary fine thread, have certain self-locking ability, but the precision of the screw is not high (6 h, 6 h).In the impact of full model stainless steel pneumatic pipe joint, vibration or system pulse environment, reduce the self-locking performance of each joint and nut, produce loose, do not seal the outer cone of the joint body and hoop, production.Live leak.With the oil pressure of Kwipe pipe joint, the wide use of air pressure industry and the improvement of the level of science and technology, overseas companies have made a lot of technical improvements on the weakness of Kwipe pipe joint, the performance is better, the most used flight is credible.For example, Parker company based on (1) cavelli pipe joint, improved three generations (mainly, after the change of kayak structure (the rubber pipe joint currently used in China is the D type designed in 1956), introduced EO progressive pipe joint in 1980, and EE22 leather pipe joint in 1993;EO22 is provided with an oil-resistant rubber seal ring located between the inner cone of the joint body and the outer wall of the steel tube. The joint only blocks one leakage channel.Such a sealing structure is in proportion to the sealing effect and the pressure, so the sealing performance is optimized in the case of high pressure.In fact, the EE22 type conduit is a transition from a single slot connector to a double wipe type conduit connector. Among them, since the EO22 type chuck is no longer used for sealing, the positioning and anti-loosening function of the seal is mainly located in zhejiang province
