shock absorber valve seat

Shock absorber valve seat is one of the key components of the valve in the railway system, which is mainly used to support and seal the valve to ensure that the High-Speed Train Valve Seat can completely block the flow of fluids (such as gas and liquid) in the closed state. Its core function is to provide a reliable sealing surface to prevent medium leakage, while withstand the mechanical stress and medium pressure during the valve opening and closing process, to ensure the safe and efficient operation of the system.

Main role

Sealing function: closely cooperate with the valve disc (or spool) to ensure the tightness of the valve when it is closed and prevent the leakage of the medium;

Supporting role: to provide a stable installation base for the valve, to withstand the mechanical load of the valve operation;

Guiding function: In some valves, the seat also plays a role in guiding the movement of the valve disc to ensure the accuracy and stability of the valve opening and closing;

Typical application

• Brake system: In the air brake valve, the seat ensures the tightness of the brake cylinder;

• Power system: In the steam valve of the locomotive boiler, the valve seat prevents steam leakage;

• Hydraulic system: In the hydraulic control valve, the seat guarantees the sealing and flow control of the hydraulic oil.
