Abstract
A system for releasing the heavy-haul train has a control valve mounted in each of train cars. The control valve is connected to a train pipe, an auxiliary air reservoir and a brake cylinder are connected to the control valve, and an exhaust port is configured on the control valve. The exhaust port is connected to a solenoid valve. The method for improving the release performance of the heavy-haul train includes: S1: the solenoid valve in each of the train cars is powered on to close a passage between the exhaust port of the control valve and the atmosphere; S2: an automatic brake valve is regulated to inflate the train pipe; and S3: the solenoid valve in each of the train cars is powered off to open the passage between the exhaust port of the control valve and the atmosphere, so that the train is released.
