比例溢流阀

全新Rexroth力士乐比例溢流阀DBETR-1X/180G24K4M比例定压溢流阀原装进口

比例溢流阀工作原理是：比例溢流阀通过弹簧力的大小改变溢流压力大大小变化，比例电磁铁作用在弹簧上的力可以按比例调整，所以就输入信号变化比例溢流阀的压力也会变化。

定压溢流作用：在定量泵节流调节系统中，定量泵提供的是恒定流量。当系统压力增大时，会使流量需求减小。此时溢流阀开启，使多余流量溢回油箱，保证溢流阀进口压力，即泵出口压力恒定（阀口常随压力波动开启）。

稳压作用：溢流阀串联在回油路上，溢流阀产生背压，运动部件平稳性增加。

系统卸荷作用：在溢流阀的遥控口串接溢小流量的电磁阀，当电磁铁通电时，溢流阀的遥控口通油箱，此时液压泵卸荷。溢流阀此时作为卸荷阀使用。

安全保护作用：系统正常工作时，阀门关闭。只有负载超过规定的极限（系统压力超过调定压力）时开启溢流，进行过载保护，使系统压力不再增加（通常使溢流阀的调定压力比系统工作压力高10%～20%）。

实际应用中一般有：作卸荷阀用，作远程调压阀，作高低压多级控制阀，作顺序阀，用于产生背压
