Research on pressure control device and method based on air brake

At present, the structure of pressure control device applied on urban rail transit is too complex. In this research, a product with simplified structure is formed by integrating filter device, one-way valve, main control valve, auxiliary control valve, solenoid valve, throttling device, remote release air control valve, braking limit air control valve and controller. Through multiple matching experiments, the functions of the product are verified. It is a highly reliable and integrated product.
