摘　　要：动车组、城轨车辆一般采用高度阀对空气弹簧进行充排风,使车辆在不同静载荷下保持地板面距轨面的高度基本不变,空气弹簧的优点只有在采用性能良好的高度阀情况下,才能充分体现出来。介绍了高度阀的主要性能,并针对设计、检修、应用过程中高度阀出现的问题进行剖析,为高度阀检修提供了技术和理论支撑,对解决和处理高度阀出现的问题具有一定的指导意义。The air spring is filled and exhausted by leveling valve in EMU and urban rail vehicles,so that the the distance between the floor surface of vehicles and the rail surface is a constant under different static loads.The advantages of air spring can only be fully embodied when using high-performance leveling valves.The main performance characteristic of the height valve is introduced,and the problems of the height valve in the process of design,maintenance and application are analyzed.It provides theoretical support for the maintenance and manufacture of the height valve,and has certain guiding significance for solving the problems of the height valve.
