力士乐溢流阀的作用

力士乐溢流阀定压溢流作用：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）。

力士乐溢流阀稳压作用：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。

力士乐溢流阀安全保护作用：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zui高工作压力高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（串在回油路上）。溢流阀一般有两种结构：1、直动型溢流阀 。2、先导式溢流阀。对溢流阀的主要要求：调压范围大，调压偏差小，压力振摆小，动作灵敏，过载能力大，噪声小。
