The invention discloses a drain valve, a railway vehicle with the drain valve and a control method of a drain system. When the air storage equipment is in an air charging high-pressure state, the second port of the communication port between the liquid discharge valve and the outside is closed by the valve seat, and condensate in the air storage equipment is stored in the valve cavity of the liquid discharge valve, so that the condensate in the air storage equipment can be discharged out of the air storage equipment when the air storage equipment works, and the normal work of the air storage equipment is not influenced; and when the internal pressure of the air storage equipment is low and the pressure difference with the external environment or the drainage pipe is small, the valve port is closed, the second port is opened, and liquid in the second cavity is drained to the outside or the drainage pipe. That is to say, the drain valve provided by the invention realizes automatic discharge of condensate according to the working pressure of the air storage equipment, and the two stages of liquid discharge and air charging do not influence each other relatively, so that air pressure loss in the air storage equipment is avoided.

    本发明公开了一种排液阀及具有该排液阀的轨道车辆、排液系统的控制方法;当储风设备处于充风高压状态时,排液阀与外界的连通口第二口被阀座关闭,储风设备中的凝液被存储于排液阀的阀腔内部,既可以实现储风设备工作时内部凝液排出储风设备,又不影响储风设备的正常工作;当储风设备内部压力比较低,与外界环境或排水管压差小时,阀口关闭,第二口打开,第二腔室内的液体被排出外界或排至排水管。也就是说,本文所提供的排液阀根据储风设备工作压力,实现凝液的自动排出,且排液与充风两阶段相对互不影响,避免储风设备内部空气压力损失。
