溢流阀，减压阀的区别和工作原理 通过安全阀，溢流阀，减压阀的工作原理及结构特点，及用途详细介绍了减压阀概念股溢流阀 安全阀之间的区别。 1.溢流阀进口压力不变，减压阀出口压力不变 2.溢流阀进出油口不通，减压阀进出油口相通 3.溢流阀阀芯由闭到开，减压阀阀芯由开到小(闭) 4.溢流阀基本上内泄， 减压阀外泄 5.先导式溢流阀导阀上的油引自进油口，先导式减压阀导阀上的油引自出油口 溢流阀:(保证进油口的压力不变) 低压益流阀是顺序阀的变形(即内部泄漏的顺序阀)，利用弹簧作用力和回油回路油压力来一进油压力进行平衡。 溢流阀分为直动式和先导式:直动式油压是靠弹簧直接平衡(不利用先导阀回油的油压力)，一般只作为低压用及安全阀用。 应用: 1.作安全阀防止过载，此阀是常闭的，当阀前的压力不**过某一预调的较**，此阀关闭不溢油， 通常多用于带变量泵 系统，其所控制的过载压力，一般比系统的工作压力高8-10%。 2.作溢流阀， 北京华德液压全系列 具体型号及报价请联系客服 北京华德换向阀部分型号如下： 4WE10F31B/CW220-50N9Z4 4WE10F31B/CW220-50N9Z5 4WE10F31B/CW220-50N9Z5L 4WE10F31B/CW220-50NZ4 4WE10F31B/CW220-50NZ5 4WE10F31B/CW220-50NZ5L 4WE10G20B/AG24N 4WE10G20B/AW220-50 4WE10G20B/OAG24N 4WE10G20B/OAW220-50N 4WE10G20B/OFAG24N 4WE10G20B/OFAW220-50N 4WE10G31B/CG24N9Z4 4WE10G31B/CG24N9Z5 4WE10G31B/CG24N9Z5L 4WE10G31B/CG24NZ4 4WE10G31B/CG24NZ5 4WE10G31B/CG24NZ5L 4WE10G31B/CW220-50N9Z4 4WE10G31B/CW220-50N9Z5 4WE10G31B/CW220-50N9Z5L 4WE10G31B/CW220-50NZ4 4WE10G31B/CW220-50NZ5 4WE10G31B/CW220-50NZ5L 4WE10H20B/OFAG24N 4WE10H20B/OFAW220-50N 4WE10H31B/CG24N9Z4 4WE10H31B/CG24N9Z5 4WE10H31B/CG24N9Z5L 4WE10H31B/CG24NZ4 4WE10H31B/CG24NZ5 4WE10H31B/CG24NZ5L 4WE10H31B/CW220-50N9Z4 4WE10H31B/CW220-50N9Z5 4WE10H31B/CW220-50N9Z5L 4WE10H31B/CW220-50NZ4 4WE10H31B/CW220-50NZ5 4WE10H31B/CW220-50NZ5L 4WE10H31B/OFCG24N9Z4 4WE10H31B/OFCG24N9Z5 4WE10H31B/OFCG24N9Z5L 4WE10H31B/OFCG24NZ4 4WE10H31B/OFCG24NZ5 4WE10H31B/OFCG24NZ5L 4WE10H31B/OFCW220-50N9Z4 4WE10H31B/OFCW220-50N9Z5
