DBDS6K18/315力士乐溢流阀是上海韦米机电设备有限公司主营产品之一，德国REXROTH全新原装进口，质量保证，现货***供应；销售***：021-61116913；联系人：雷青；在线***：2896079243；移动***：13296124913；进口品牌备件上海优质供应商，常规产品现货供应。欢迎新老客户来电咨询采购！DBDS6K18/315力士乐溢流阀先导溢流阀的主阀上腔压力，是由先导阀加于控制的。如果先导阀正常工作，即主阀上腔有先导阀规定的压力，则整个溢流阀就会在系统压力到达调定压力时其主阀口打开一定的开度，一方面能将系统多余流量流回油箱，另一方面又能维持系统的压力为先导阀的调定值。可见，先导阀主要管压力，主阀服从先导阀的***，在先导阀动作时将主阀口开到合适大小，正好将多余流量流出去，又不影响系统压力。DBDS6K18/315力士乐溢流阀DBDS6K18/315力士乐溢流阀力士乐溢流阀DBEE6-1X/50G24K31V力士乐溢流阀DBEE6-1X/50G24NK31M力士乐溢流阀DBEE6-1X/50YG24K31M力士乐溢流阀DBEM10G-3X/200YK4-510力士乐溢流阀DBEM10-3X/200YG24NK4-308力士乐溢流阀DBEM10-3X/315XYG24K4-370力士乐溢流阀DBEM10-3X/50XYK4-246力士乐溢流阀DBEM10-5X/100XYG24K4M力士乐溢流阀DBEM10-5X/100YG24K4M力士乐溢流阀DBEM10-5X/100YG24K4M-1力士乐溢流阀DBEM10-5X/100YG24NK4M力士乐溢流阀DBEM10-5X/100YG24NK4M-1力士乐溢流阀DBEM10-5X/100YG24NK4V力士乐溢流阀DBEM10-5X/200XYG24K4M力士乐溢流阀DBEM10-5X/200XYG24K4M-1力士乐溢流阀DBEM10-5X/200XYG24K4M-5力士乐溢流阀DBEM10-5X/200XYG24NK4M力士乐溢流阀DBEM10-5X/200YG24K4M力士乐溢流阀DBEM10-5X/200YG24K4M-1力士乐溢流阀DBEM10-5X/200YG24K4V力士乐溢流阀DBEM10-5X/200YG24NK4M力士乐溢流阀DBEM10-5X/200YG24NK4M-1力士乐溢流阀DBEM10-5X/315XYG24K4M力士乐溢流阀DBEM10-5X/315XYG24K4M-1力士乐溢流阀DBEM10-5X/315XYG24NK4M力士乐溢流阀DBEM10-5X/315YG24K4M力士乐溢流阀DBEM10-5X/315YG24K4M-1力士乐溢流阀DBEM10-5X/315YG24K4V力士乐溢流阀DBEM10-5X/315YG24NK4M力士乐溢流阀DBEM10-5X/315YG24NK4M-1力士乐溢流阀DBEM10-5X/350XYG24K4M力士乐溢流阀DBEM10-5X/350YG24K4M力士乐溢流阀DBEM10-5X/350YG24NK4M力士乐溢流阀DBEM10-5X/50XYG24K4M力士乐溢流阀DBEM10-5X/50XYG24NK4M力士乐溢流阀DBEM10-5X/50YG24K4M力士乐溢流阀DBEM10-5X/50YG24K4M-1力士乐溢流阀DBEM10-5X/50YG24NK4M力士乐溢流阀DBEM20-3X/200YG24NK4-340力士乐溢流阀DBEM20-5X/100YG24K4M力士乐溢流阀DBEM20-5X/100YG24K4M-1力士乐溢流阀DBEM20-5X/200XYG24K4M力士乐溢流阀DBEM20-5X/200XYG24K4M-1力士乐溢流阀DBEM20-5X/200XYG24K4M-2力士乐溢流阀DBEM20-5X/200XYG24NK4M力士乐溢流阀DBEM20-5X/200XYG24NK4M-1力士乐溢流阀DBEM20-5X/200YG24K4M力士乐溢流阀DBEM20-5X/200YG24K4M-1力士乐溢流阀DBEM20-5X/200YG24K4V力士乐溢流阀DBEM20-5X/200YG24NK4M力士乐溢流阀DBEM20-5X/315XYG24K4M力士乐溢流阀DBEM20-5X/315XYG24K4M-1力士乐溢流阀DBEM20-5X/315XYG24NK4M力士乐溢流阀DBEM20-5X/315XYG24NK4M-2力士乐溢流阀DBEM20-5X/315YG24K4M力士乐溢流阀DBEM20-5X/315YG24K4M-1力士乐溢流阀DBEM20-5X/315YG24K4V力士乐溢流阀DBEM20-5X/315YG24NK4M力士乐溢流阀DBEM20-5X/315YG24NK4M-1力士乐溢流阀DBEM20-5X/350XYG24K4M力士乐溢流阀DBEM20-5X/350YG24K4M力士乐溢流阀DBEM20-5X/350YG24K4V力士乐溢流阀DBEM20-5X/350YG24NK4M力士乐溢流阀DBEM20-5X/50YG24K4V力士乐溢流阀DBEM20-5X/50YG24NK4M力士乐溢流阀DBEM30-3X/100XYG24K4M力士乐溢流阀DBEM30-3X/100YG24K4M力士乐溢流阀DBEM30-3X/200XYG24K4M力士乐溢流阀DBEM30-3X/200XYG24NK4M力士乐溢流阀DBEM30-3X/200YG24K4M力士乐溢流阀DBEM30-3X/200YG24K4V力士乐溢流阀DBEM30-3X/200YG24NK4M力士乐溢流阀DBEM30-3X/315XYG24K4M力士乐溢流阀DBEM30-3X/315YG24K4M力士乐溢流阀DBEM30-3X/315YG24K4M-422力士乐溢流阀DBEM30-3X/315YG24NK4M力士乐溢流阀DBEM30-3X/350XYG24K4M力士乐溢流阀DBEM30-3X/350YG24K4M力士乐溢流阀DBEM30-3X/350YG24NK4M力士乐溢流阀DBEMC30-3X/200YG24K4-340力士乐溢流阀DBEMC30-3X/315YG24K4力士乐溢流阀DBEMC30-3X/315YG24NK4力士乐溢流阀DBEMC-3X/100YG24K4力士乐溢流阀DBEMC-3X/200G24K4-267力士乐溢流阀DBEMC-3X/200YG24K4DBDS6K18/315力士乐溢流阀对节流阀的性能要求是：·流量调节范围大，流量一压差变化平滑；·内泄漏量小，若有外泄漏油口，外泄漏量也要小；·调节力矩小，动作灵敏。节流阀(throttlevalve)的外形结构与截止阀并无区别，只是它们启闭件的形状有所不同。节流阀的启闭件大多为圆锥流线型，通过它改变通道截面积而达到调节流量和压力。节流阀供在压力降极大的情况下作降低介质压力之用。介质在节流阀瓣和阀座之间流速很大，以致使这些零件表面很快损坏－即所谓汽蚀现象。为了尽量减少汽蚀影响，阀瓣采用耐汽蚀材料（合金钢制造）并制成***角为140～180的流线型圆锥体，这还能使阀瓣能有较大的开启高度，一般不推荐在小缝隙下节流。DBDS6K18/315力士乐溢流阀力士乐溢流阀DBDS10G1X/100力士乐溢流阀DBDS10G1X/100/12力士乐溢流阀DBDS10G1X/100/2力士乐溢流阀DBDS10G1X/100/5力士乐溢流阀DBDS10G1X/100/V力士乐溢流阀DBDS10G1X/100/VB力士乐溢流阀DBDS10G1X/100-075/12力士乐溢流阀DBDS10G1X/100-70力士乐溢流阀DBDS10G1X/100E力士乐溢流阀DBDS10G1X/100J力士乐溢流阀DBDS10G1X/100MT力士乐溢流阀DBDS10G1X/100P080力士乐溢流阀DBDS10G1X/100SO102力士乐溢流阀DBDS10G1X/100SO60力士乐溢流阀DBDS10G1X/100V/12力士乐溢流阀DBDS10G1X/100V/5力士乐溢流阀DBDS10G1X/100VB力士乐溢流阀DBDS10G1X/10SO41力士乐溢流阀DBDS10G1X/110B力士乐溢流阀DBDS10G1X/120B力士乐溢流阀DBDS10G1X/125B力士乐溢流阀DBDS10G1X/130B力士乐溢流阀DBDS10G1X/130VB力士乐溢流阀DBDS10G1X/135B力士乐溢流阀DBDS10G1X/140B力士乐溢流阀DBDS10G1X/150B力士乐溢流阀DBDS10G1X/155B力士乐溢流阀DBDS10G1X/160B力士乐溢流阀DBDS10G1X/170B力士乐溢流阀DBDS10G1X/175B力士乐溢流阀DBDS10G1X/180B力士乐溢流阀DBDS10G1X/190B力士乐溢流阀DBDS10G1X/200力士乐溢流阀DBDS10G1X/200/12力士乐溢流阀DBDS10G1X/200/5力士乐溢流阀DBDS10G1X/200/50力士乐溢流阀DBDS10G1X/200/V力士乐溢流阀DBDS10G1X/200-110SO60力士乐溢流阀DBDS10G1X/200-130力士乐溢流阀DBDS10G1X/200-140力士乐溢流阀DBDS10G1X/200-150力士乐溢流阀DBDS10G1X/200-160力士乐溢流阀DBDS10G1X/200-170力士乐溢流阀DBDS10G1X/200-180力士乐溢流阀DBDS10G1X/200-180SO60力士乐溢流阀DBDS10G1X/200B力士乐溢流阀DBDS10G1X/200E力士乐溢流阀DBDS10G1X/200J力士乐溢流阀DBDS10G1X/200JV力士乐溢流阀DBDS10G1X/200MK力士乐溢流阀DBDS10G1X/200MT力士乐溢流阀DBDS10G1X/200P120SO450力士乐溢流阀DBDS10G1X/200P140力士乐溢流阀DBDS10G1X/200SO32力士乐溢流阀DBDS10G1X/200SO450力士乐溢流阀DBDS10G1X/200SO52力士乐溢流阀DBDS10G1X/200SO60力士乐溢流阀DBDS10G1X/200V/12力士乐溢流阀DBDS10G1X/200VB力士乐溢流阀DBDS10G1X/200VSO102力士乐溢流阀DBDS10G1X/205B力士乐溢流阀DBDS10G1X/210B力士乐溢流阀DBDS10G1X/210E力士乐溢流阀DBDS10G1X/210VB力士乐溢流阀DBDS10G1X/220B力士乐溢流阀DBDS10G1X/220VB力士乐溢流阀DBDS10G1X/230B力士乐溢流阀DBDS10G1X/240B力士乐溢流阀DBDS10G1X/25力士乐溢流阀DBDS10G1X/25/12力士乐溢流阀DBDS10G1X/25/V力士乐溢流阀DBDS10G1X/250B+CERTIFICA***力士乐溢流阀DBDS10G1X/25-10力士乐溢流阀DBDS10G1X/25-10V力士乐溢流阀DBDS10G1X/25-20力士乐溢流阀DBDS10G1X/25-20V力士乐溢流阀DBDS10G1X/25P15力士乐溢流阀DBDS10G1X/25V/12力士乐溢流阀DBDS10G1X/25VSO102力士乐溢流阀DBDS10G1X/260B力士乐溢流阀DBDS10G1X/275B力士乐溢流阀DBDS10G1X/280B力士乐溢流阀DBDS10G1X/300B力士乐溢流阀DBDS10G1X/30B力士乐溢流阀DBDS10G1X/30VB力士乐溢流阀DBDS10G1X/30VE力士乐溢流阀DBDS10G1X/315力士乐溢流阀DBDS10G1X/315/12力士乐溢流阀DBDS10G1X/315-220力士乐溢流阀DBDS10G1X/315-220V力士乐溢流阀DBDS10G1X/315-225SO5
