Rexroth力士乐溢流阀先导阀 DBT ZDBT系列是一种液压压力控制阀,在液压设备中主要起定压溢流作用,稳压,系统卸荷和安全保护作用。 溢流阀的作用 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。 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。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)。
