Oil cylinder manufacturer in High pressure ball valve How to solve pressure test?

High pressure ball valve is a valve that automatically opens and closes through the flow of the medium itself to prevent the medium from flowing back. It is also called a check valve, a one-way valve, a reverse valve, and a back pressure valve. The check valve is an automatic valve, which is mainly used to prevent the reverse flow of the medium, prevent the reversal of the pump and drive motor, and release the container medium.

The check valve can also be used to supply the pipeline for the auxiliary system in which the pressure may exceed the system pressure. Check valves are mainly divided into rotary check valves (rotating with the center of gravity) and lift check valves (moving along the axis). Check valve This type of valve only allows the medium to flow in one direction, preventing the flow in the opposite direction. Usually, such a valve works automatically, and the valve disc is opened due to the fluid pressure of one-way flow. When the fluid flows in the opposite direction, the fluid pressure and the self polymerization valve body of the valve body act on the valve seat to block the flow. Check valves are of this type, including rotary check valve and lift check valve. The rotary check valve freely butts against the inclined seat surface of the valve body such as the door through the hinge mechanism. In order to ensure that the valve body reaches the proper position of the valve seat surface each time, the valve body is designed as a hinge mechanism. The valve body has enough room for rotation, and the valve body really contacts the valve seat. The valve body can be made of metal, or embedded with leather, rubber, or synthetic target surface, depending on the performance requirements.
