The article discusses some factors which influence the performance of the non-mechanical valve, such as system pressure, air flow-rate, air charging mode and characteristics of ash et al.
With the charging features of the air braking system on the 10 000 t heavy haul train as the research object, the change of pressure in the auxiliary reservoir during charging on train is researched.
