EUS- quick plug connector
Detailed
The stainless steel pipe joint is a kind of convenient, reliable, easy to install and disassemble medium and high pressure pipe connection, since coming into being, has been widely used in the mechanical, hydraulic and other industries.
The sleeve joint first appeared in the early 1930s. After more than half a century of development, the sleeve joint has become the most widely used pipe joint in the world.
Single card sleeve joint
(single) bayonet type pipe joint is composed of bayonet, connector body and nut. The structure is shown as follows:
1. 1 (single) sealing principle of bayonet type pipe joint:
During the assembly, tighten the nut, the nut is pushed forward along the cone axis inside the joint body under the screw force of the nut, and the nut is attached to the cone inside the joint body.The sleeve is deformed, and the cutting edge part of it shrinks inward and cuts into the surface wall of the steel tube. The full model stainless steel joint forms a seal with the steel tube.At the same time, the outer cone of the sleeve is arched upward to form the back of the turtle, which is in close contact with the cone inside the joint, forming a seal. This seal structure is a rigid line seal, which can withstand the pressure of the shaoxing flamed joint under 40MPa. It is mainly used for the gas seal of hydraulic and full model stainless steel joint manufacturers.
1. 2 (single) installation characteristics of bayonet type pipe joint:
Due to (single) stainless steel joint, stainless steel pipe joint sleeve type pipe joint sealing performance depends on the sleeve edge can be uniform, moderate cut into the steel pipe surface wall (the outer diameter is 6 ~ 16 steel pipe, sleeve cut depth t ≥0. 3;The outer diameter is 18 ~ 35 steel pipe, sleeve cut deep t ≥0. 5);The outer cone of the clip is arched upward to form a uniform contact between the back and the inner cone of the joint.Sleeve cut into the wall of the steel tube table and deformation needs a considerable external force, according to the relevant information: installed with a 6-10 sleeve of tightening force is 64N ~ 115N, with a 16 of 259N, 18 of 450N;Such a big moment in the vise operation has certain difficulties, not to mention in the construction site, so before the assembly must be in the special card sleeve preassembly on the preassembly.Before assembly, otherwise, the qualification rate of one assembly is not higher than 60%.
