Sealing performance of bayonet type pipe joint
(single) bayonet type pipe fittings have not been popularized in China since the 1970s, and are used in hydraulic pressure, full model stainless steel quick plug fittings pneumatic pipeline under 40MPa.A large number of applications have shown that the (single) bayonet connection is not
The sleeve
1. 3. 1 full model stainless steel quick screw joint without temperature compensation function, sealing performance greatly decreased in the environment of large temperature change
(single) pipe connector of cutting sleeve type has the parts precision and heat treatment requirements is not high, such as card sets of outer cone, cone surface roughness in the body parts, zhoushan transition joints joint only 1.6), the assembly is difficult to assure card sets of uniform blade, cut into the steel tube wall, according to the design value card set of outer cone cone body contact, it's hard to evenly and joint plus card, joint and steel pipe material is qualitative different, different thermal expansion coefficient, when the temperature change is big, after heat bilges cold shrink (assembly after card sets and deformation of steel pipe produced long), card sets and between the steel tube, card sets and possible formation of space between the connector body, from leaking.Therefore, in the place where the temperature changes greatly, because there is no temperature difference compensation function, the (single) bayonet type pipe joint is easy to produce leakage.If our factory product is in use, assemble to use in summer, all card sleeve type joint all have no leak, but use to northwest area in winter to discover some pipe joint ooze oil.
1. 3. 2 wenzhou hydraulic joint repeated disassembly poor performance: disassembly and assembly for many times easy to leak, the card sleeve or joint body can not be used
Due to the (single) stainless steel joint and stainless steel pipe joint sleeve type pipe joint after assembly, the sleeve and the steel pipe have a long-term deformation, rather than elastic deformation, during the reassembly, the second deformation between the sleeve and the joint body taper can no longer produce;After disassembly and assembly for many times, leakage is easy to occur because there is no assembly compensation amount between the clamp sleeve and the joint body.
