08114030170811403017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）。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***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、先导型溢流阀本公司是力士乐REXROTH武汉一级代理，如有需求请联系力士乐REXROTH销售负责人：刘女士手机：15827383769电话：027-87856628传真：027-87850991***：2578874787邮箱：2578874787@***.comDBD溢流阀R900331916DBDH10K1X/630VR900334105DBDA6K1X/315VR900334729DBDH20K1X/25VR900343869DBDH10K1X/400VR900361835DBDH6P1X/315VR900381021DBDA20K1X/100VR900403701DBDH10G1X/100VR900406900DBDH10K1X/25VR900420245DBDS6K1X/25R900420276DBDS10K1X/25R900420662DBDA6G1X/400VR900422542DBDS20K1X/25R900422543DBDS30K1X/25R900422544DBDS20G1X/25R900423711DBDS30K1X/50VR900423712DBDS30P1X/100R900423713DBDS30P1X/100VR900423714DBDS30P1X/200R900423715DBDS30P1X/315R900423716DBDS30P1X/50R900423717DBDS6G1X/100R900423718DBDS6G1X/25R900423719DBDS6G1X/200R900423720DBDS6G1X/315R900423721DBDS6G1X/400R900423722DBDS6G1X/50R900423723DBDS6K1X/100R900423724DBDS6K1X/200R900423725DBDS6K1X/315R900423726DBDS6K1X/400R900423727DBDS6K1X/50R900423728DBDS6P1X/100R900423729DBDS6P1X/200R900423730DBDS6P1X/315R900423731DBDS6P1X/400R900423732DBDS6P1X/50R900423733DBDS8G1X/100R900423734DBDS8G1X/200R900423735DBDS8G1X/315R900423743DBDS10G1X/25R900423758DBDS30G1X/100VR900423780DBDA6K1X/25R900423860DBDA10G1X/100R900423871DBDA20K1X/100R900423889DBDS10G1X/25VR900423891DBDH10K1X/100R900424082DBDS20K1X/315VR900424108DBDH20G1X/50R900424109DBDH20K1X/100R900424112DBDH20K1X/50R900424140DBDS10G1X/200R900424146DBDS10G1X/50VR900424147DBDS10K1X/100R900424148DBDS10K1X/100VR900424149DBDS10K1X/200R900424150DBDS10K1X/315R900424151DBDS10K1X/315VR900424152DBDS10K1X/400R900424153DBDS10K1X/50R900424154DBDS10K1X/50VR900424155DBDS10P1X/100R900424157DBDS10P1X/200R900424158DBDS10P1X/315R900424159DBDS10P1X/315VR900424162DBDS15G1X/100R900424163DBDS15G1X/200R900424165DBDS15G1X/315R900424167DBDS15G1X/50R900424172DBDS20G1X/200R900424174DBDS20G1X/315R900424175DBDS20G1X/400R900424178DBDH10G1X/200R900424183DBDH10K1X/315R900424184DBDH10K1X/400R900424185DBDH10K1X/50R900424188DBDH10G1X/100)
