Air brake accessories mainly include the following types:
Main valve: The core part, responsible for converting compressed air into brake pressure.
Acceleration valve: Regulates the flow of compressed air entering the brake cylinder to achieve smooth acceleration and deceleration.
Reducing valve: Regulates the pressure in the brake cylinder to prevent excessive pressure from damaging other components.
Safety valve: Prevents accidents caused by excessive pressure in the brake cylinder.
Distribution valve: Distributes the compressed air in the brake line to each brake cylinder.
These accessories work together to achieve precise control of the train by adjusting the amount of compressed air.
