摘要
介绍了城市轨道车辆用中继阀的结构组成与工作原理,分析了中继阀输入预控压力与输出压力之间压差产生的原因,并提出了减小压差的措施。
The structure composition and working principle of relay valves for urban rail vehicles are described.The causes to pressure difference between input pre-control pressure and the output pressure of relay valves are analyzed.And measures to reduce the pressure difference are given.
