How to deal with air leakage of self sealing locking pneumatic ball valve
When using the vehicle, if there is slight air leakage in its own pneumatic ball valve system, which will not affect the braking and cannot be handled, it can be handled until the end of operation; If the pneumatic ball valve breaks unexpectedly, perforation or leakage is serious, and the vehicle is disposed of, the pneumatic ball valve will be cut off at the station passage. The bogie with two pneumatic ball valve sources will run 120 kilometers per hour until the wind is cut off. There is no need to cut off the whole vehicle pneumatic ball valve source, but there is no need to do the car door closing handle.
