库存力士乐液压阀 DB20-1-50/315U 武穴黎翔机电设备有限公司:18934630908 (微信同号) 内部先导式减压阀当减压阀的输出压力较高或通径较大时,用调压弹簧直接调压,则弹簧刚度必然过大,流量变化时,输出压力波动较大,阀的结构尺寸也将增大。为了克服这些缺点,可采用先导式减压阀。先导式减压阀的工作原理与直动式的基本相同。先导式减压阀所用的调压气体,是由小型的直动式减压阀供给的。若把小型直动式减压阀装在阀体内部,则称为内部先导式减压阀;若将小型直动式减压阀装在主阀体外部,则称为外部先导式减压阀。与直动式减压阀相比,增加了由喷嘴4、挡板3、固定节流孔9及气室B所组成的喷嘴挡板放大环节。当喷嘴与挡板之间的距离发生微小变化时,就会使B室中的压力发生根明显的变化,从而引起膜片10有较大的位移,去控制阀芯6的上下移动,使进气阀口8开大或关小、提高了对阀芯控制的灵敏度,即提高了稳压精度。 在主阀体外部还有一个小型直动式减压阀由它来控制主阀。此类阀适于通径在20mm以上,远距离(30m以内)、高处、危险处、调压困难的场合。 R901093524 DB10-2-5X/350P350 R900249511 DB10-2-5X/350V R978862260 DB10-2-5X/350V/12 R901020317 DB10-2-5X/350VD R900501045 DB10-2-5X/350X R901094599 DB10-2-5X/350X./12 R901052268 DB10-2-5X/350XU R901246914 DB10-2-5X/350XV R900511665 DB10-2-5X/350XY R901056913 DB10-2-5X/350XY/12 R900548408 DB10-2-5X/350XYU R900597420 DB10-2-5X/350Y R900778197 DB10-2-5X/350Y/12 R900788117 DB10-2-5X/350YD R901317058 DB10-2-5X/350YE R900500117 DB10-2-5X/350YV R900546291 DB10-2-5X/40B R901048715 DB10-2-5X/40E R900590645 DB10-2-5X/50 R900951239 DB10-2-5X/50-15XV R900911082 DB10-2-5X/50-30 R900535930 DB10-2-5X/50/12 R900939229 DB10-2-5X/500 SO99 R900577509 DB10-2-5X/500-480 SO99 R901075337 DB10-2-5X/500-480Y SO699 R900970219 DB10-2-5X/500V SO99 R901085936 DB10-2-5X/500Y SO699 R900929814 DB10-2-5X/50B R901022588 DB10-2-5X/50D R901034001 DB10-2-5X/50E R901251515 DB10-2-5X/50P20 R900725852 DB10-2-5X/50P25 R900961072 DB10-2-5X/50P30 R900579303 DB10-2-5X/50U R901444731 DB10-2-5X/50U/12 R900703457 DB10-2-5X/50UV R900598054 DB10-2-5X/50V R900511831 DB10-2-5X/50X R900536300 DB10-2-5X/50XU R900508332 DB10-2-5X/50XV R900734775 DB10-2-5X/50XY R900976222 DB10-2-5X/50XY/12 R900516068 DB10-2-5X/50XYU R900597342 DB10-2-5X/50Y R900921126 DB10-2-5X/50Y/12 R900509825 DB10-2-5X/50YU R900774148 DB10-2-5X/50YV R978012490 DB10-2-5X/50YV/12 R901321941 DB10-2-5X/70VE R901215690 DB10-2-5X/80E R900546292 DB10-2-5X/80VB R901267227 DB10-2-5X=200V R900559323 DB10-2-5X=200X=PL R901365763 DB10-2-5X=315 R901395373 DB10-2-5X=70VE R978870247 DB10-2-5X/100XU/12 R978865805 DB10-2-5X/100XV/12 R978875474 DB10-2-5X/200UV/12 R978896298 DB10-2-5X/200X/12 R978890814 DB10-2-5X/200YU/12 R978862672 DB10-2-5X/315XUV/12 R978863597 DB10-2-5X/315XV/12 R978865225 DB10-2-5X/315YUV/12 R978875197 DB10-2-5X/315YV/12 R978892751 DB10-2-5X/350X/12 R978908614 DB10-2-5X/350XV/12 R978874041 DB10-2-5X/50V/12 R900787149 DB20-2-5X/160YE R900919800 DB20-2-5X/165B R900769567 DB20-2-5X/165E R900546391 DB20-2-5X/170B R901138990 DB20-2-5X/170E R900546392 DB20-2-5X/175B R900769617 DB20-2-5X/175E R900546393 DB20-2-5X/180B R900773207 DB20-2-5X/180E R900973724 DB20-2-5X/190B R901172281 DB20-2-5X/190E R900590768 DB20-2-5X/200 R900930933 DB20-2-5X/200-120 R901225115 DB20-2-5X/200-150 R901207674 DB20-2-5X/200-150XY R900908035 DB20-2-5X/200-160 R900737382 DB20-2-5X/200-180 R900535931 DB20-2-5X/200/12 R900558858 DB20-2-5X/200=LB R900597123 DB20-2-5X/200B R901003073 DB20-2-5X/200D R901003073 DB20-2-5X/200D R900769587 DB20-2-5X/200E R900704830 DB20-2-5X/200P175V R900519775 DB20-2-5X/200U R900564130 DB20-2-5X/200UB R900707530 DB20-2-5X/200UV R900948744 DB20-2-5X/200UV/12 R900513667 DB20-2-5X/200V R900705853 DB20-2-5X/200V/12 R901231581 DB20-2-5X/200VD R900595893 DB20-2-5X/200X R900554165 DB20-2-5X/200X SO566 R900561259 DB20-2-5X/200X/12 R900523527 DB20-2-5X/200XU R900959855 DB20-2-5X/200XUV R900919860 DB20-2-5X/200XV R900500218 DB20-2-5X/200XY R900549653 DB20-2-5X/200XY/12 R900565471 DB20-2-5X/200XYU R900966321 DB20-2-5X/200XYV R900596528 DB20-2-5X/200Y R900918105 DB20-2-5X/200Y/12 R900903802 DB20-2-5X/200Y/50 R900501297 DB20-2-5X/200YB R900787948 DB20-2-5X/200YD R900788059 DB20-2-5X/200YE R901145333 DB20-2-5X/200YU R900506323 DB20-2-5X/200YV R900247762 DB20-2-5X/200YV/12 R901406071 DB20-2-5X/200YVD R900546399 DB20-2-5X/210B R900769388 DB20-2-5X/210E R900932814 DB20-2-5X/210UB R900546400 DB20-2-5X/210VB
