Rust and falling off of throttle valve Due to the failure of one-way valve of toilet collector in some vehicles, when there is no wind pressure in the main air pipe, the cold water countercurrent main air pipe, or the locomotive air source and the air source in the warehouse are not dry during maintenance, a large amount of water is easy to form inside the pneumatic butterfly valve. Although the throttle valve is designed with anti rust treatment, it will also rust or even rust because it is immersed in water for a long time.
Some throttle valves are fastened with screws. The screws are easy to loosen during vibration. The valve seat and valve sleeve are loose and detached, causing the throttle valve to fall off. In serious cases, other relevant parts of the pneumatic butterfly valve will also be damaged.
