Abstract

The present application relates to a rail vehicle empty-load vehicle valve adjustment device, method and braking control device. Among them, the method includes the following steps: the state reset step, fully releasing the second adjustment lever; the current parameter testing step, adjusting the air spring pressure to the empty spring pressure of an empty vehicle and the empty spring pressure of a heavy vehicle through a pressure regulating valve, and obtaining the corresponding actual pressure. In the parameter adjustment step, turn the third adjustment rod, the first adjustment rod and the second adjustment rod and adjust the pressure regulating valve respectively, so that the brake cylinder pressure reaches the corresponding set value; in the pressure verification step, through the adjustment The pressure valve adjusts the air spring pressure to the set air spring pressure value, and verifies whether the actual brake cylinder pressure at this time meets the requirements. If it meets the requirements, the adjustment is completed. It solves the problem of difficult adjustment of the valve for empty and heavy trucks after loading, and the on-site adjustment of the valve for empty and heavy trucks can be realized only through external tooling without the need for vehicle operation.

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...
