万福乐防爆溢流阀BVBPM22-80G24/L9
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。
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gao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。
