Abstract

The invention relates to a rail vehicle empty and load valve adjusting device and method and a brake control device. The method comprises the following steps: a state resetting step: completely releasing a second adjusting rod; a current parameter testing step: adjusting the air spring pressure to empty vehicle air spring pressure and heavy vehicle air spring pressure through a pressure regulating valve, and obtaining corresponding actual brake cylinder pressure; a parameter adjusting step: respectively rotating a third adjusting rod, a first adjusting rod and a second adjusting rod and adjusting a pressure adjusting valve to enable the pressure of the brake cylinder to reach a corresponding set value; and a pressure verification step: adjusting the air spring pressure to a set air spring pressure value through a pressure regulating valve, verifying whether the actual brake cylinder pressure at the moment meets the requirement or not, and if the actual brake cylinder pressure meets the requirement, finishing the adjustment. The problem that the empty and load valves are difficult to adjust after being loaded is solved, vehicle operation is not needed, and on-site adjustment of the empty and load valves can be achieved only through an external tool.

Description

technical field [0001] The present application relates to the technical field of rail transit vehicles, in particular to a rail vehicle empty-load vehicle valve adjustment device, method and brake control device. Background technique [0002] The empty-load train valve is an important part of the brake system of EMUs and urban rail vehicles. It is installed inside the brake control device. Its main function is to automatically adjust the pressure of the brake cylinder according to the change of the vehicle load during emergency braking, so as to ensure The emergency braking deceleration is consistent under different loads. At the same time, when the air spring is broken, the pressure of the brake cylinder can be equal to the pressure of the brake cylinder in the no-load state, so as to avoid the loss of braking force. It can also limit the maximum value of the brake cylinder pressure during normal braking to ensure that the normal braking force does not exceed the maximum e...
