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(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。DBEM10-7X/200YG24K4M力士乐液压阀现货供应BoschDBETBX-1X/28G24-37Z4MBoschDBETBX-1X/80G24-37Z4M2BoschDBETBX-1X/180G24-37Z4MBoschDBETBX-1X/250G24-37Z4M2BoschDBETBX-1X/315G24-37Z4MBoschDBETBEX-1X/80G24k31A1MBoschDBETBEX-1X/180G24k31A1MBoschDBETBEX-1X/250G24k31A1MBoschDBETBEX-1X/315G24k31A1MBoschDBETBEX-1X/80G24k31F1MBoschDBETBEX-1X/180G24k31F1MBoschDBETBEX-1X/315G24k31F1MBoschDBETFX-1X/80G24-27NZ4MBoschDBETFX-1X/180G24-27NZ4MBoschDBETFX-1X/250G24-27NZ4MBoschDBETFX-1X/315G24-27NZ4MBoschDBETX-1X/50G24-8NZ4MBoschDBETX-1X/80G24-8NZ4MBoschDBETX-1X/180G24-8NZ4MBoschDBETX-1X/250G24-8NZ4MBoschDBETX-1X/315G24-8NZ4MBoschDBETX-1X/50G24-25NZ4MBoschDBETX-1X/80G24-25NZ4MBoschDBETX-1X/180G24-25NZ4MBoschDBETX-1X/250G24-25NZ4MBoschDBETX-1X/315G24-25NZ4MBoschDBEP6A06-1X/4G24K4MR900955079BoschDBEP6B06-1X/4G24K4MR900955080BoschDBEP6C06-1X/4G24K4MR900955082BoschDBET-6X/50G24K4VR901000842BoschDBET-6X/100G24K4VR901000845BoschDBET-6X/200G24K4VR901000846BoschDBET-6X/315G24K4VR901000847BoschDBET-6X/350G24K4VR901000848BoschDBETE-6X/50G24K31A1VR901029966BoschDBETE-6X/100G24K31A1VR901029967BoschDBETE-6X/200G24K31A1VR901029968BoschDBETE-6X/315G24K31A1VR901029969BoschDBETE-6X/350G24K31A1VR901029970BoschDBETR-1X/30G24K4MR900954438BoschDBETR-1X/80G24K4MR900334966BoschDBETR-1X/180G24K4MR900491698BoschDBETR-1X/230G24K4MR900370146BoschDBETR-1X/315G24K4MR900485944BoschDBETR-1X/350G24K4MR900352424BoschDBEBE6X-1X/80G24K31A1MBoschDBEBE6X-1X/180G24K31A1MBoschDBEBE6X-1X/315G24K31A1MBoschDBEBE6X-1X/80G24K31F1MBoschDBEBE6X-1X/180G24K31F1MBoschDBE10Z-1X/180XYG24-8NZ4MBoschDBE10Z-1X/315XYG24-8NZ4MBoschDBEB10Z-1X/180XYG24-37Z4MBoschDBEB10Z-1X/315XYG24-37Z4MBoschDBEBE10Z-1X/180XYG24K31A1MBoschDBEBE10Z-1X/315XYG24K31A1MBoschDBEME10-5X/50YG24K31MR900908585DBETBEX-1X/250G24K31A1MDBETBEX-1X/180G24K31F1MDBEBE6X-1X/315G24K31A1MDBEBE6X-1X/180G24K31A1MDBEBE6X-1X/80G24K31A1MDBEBE6X-1X/180G24K31F1MDREBE6X-1X/175MG24K31A1MDREBE6X-1X/310MG24K31A1MDREBE6X-1X/75MG24K31A1M)
