The role of the valve stem

Release time:

2025-05-07

The main function of the valve stem is to open and close the operation of the driving valve petals.Valve stems drive the valve petals by rotating or moving up and down, thereby controlling the flow of the fluid or adjusting the flow.

Specifically, the role of valve stems includes the following aspects:

Drive valve petals open and close: The valve stems drive the valve petals by rotating or moving up and down to achieve the opening and closing function of the valve. In the ball valve, the valve stem is used to control the rotation movement of the sphere, thereby controlling the flow of the fluid.

： Regulate traffic: In some types of valves, the valve stem can also be used to regulate the flow of the fluid. By changing the openness of the valve petals, the flow of the fluid can be controlled.

To ensure the sealing performance The precise operation of the valve stem can ensure the sealing performance of the valve seat and prevent fluid leakage.

In addition, valve stems can also be divided into direct and crank types according to different transmission methods. The direct valve stem directly connects the valve petals, and the driver valve petals are rotated or up and down;

In summary, the valve stem plays a vital role in the valve. The fluid controls and adjustment of the fluid by driving the valve petals to ensure the normal operation of the system.
