Attention should be paid to sealing and buying fast joints
When the stainless steel ball valve is separated from the two joint bodies, the open and closed fast joints of the two ends are made up of the joint body, the valve spool of the stainless steel pipe plant, the coat, the steel ball, the spring and the seal. The inner cavity of the joint body has a one-way valve. The valve spool is extended outside the respective spring and pressed on the conical hole of the joint body so that the passage is closed and the oil in the two sides of the pipe is closed in the pipe. When the two joint body is connected, the two top rods in the front of the valve spool are touched to force the valve core out of the cone hole of the joint body to make the oil inside the pipe. The two joints are locked with steel balls. When working, the steel ball is pressed into the U groove of the joint body under the action of the spring, so that the joint body is connected.
It
Stainless steel pipe fittings are made of steel chrome plated steel and stainless steel hydraulic quick joints are designed for special heavy loads. The male connector and the female connector's sleeve are all hardened, and the pressure resistance and fatigue resistance are good. It adopts two stage seal, no leakage: with safety self-locking function.
The stainless steel quick connector can also quickly connect and disassemble the pipeline, and the stainless steel knot is a kind of joint without using tools. There are two open ends and two open ends. The joint is easy to assemble, but has complex structure and large local resistance loss. It is suitable for pipeline system with oil and gas as medium. The difference between the two ends of the open joint is only that the inner cavity of the joint body has no check valve. When the two joints are separated, the access can not be closed. One end of the joint is connected with the rubber hose by the three petal type hose joint, and the joint core of the hose connector is directly inserted into the quick connector.
