充液阀的充液过程为:当蓄能器的压力低于充液阀设定的下限压力时，作用在上限单向阀阀芯3上的液压力低于 导阀4左端弹簧8的作用力，使下限单向阀6关闭，上限单向阀3打开，蓄能器内的压力油经 导阀芯4、节流通道Ⅱ进入主阀右腔，推动主阀芯9克服左腔压力向左移动，逐渐降低主阀开度 DBW10B1-5X/200-6EG24N9K4 　　 DBW10B1-5X/315-6EG24N9K4 　　 DBW20B1-5X/100-6EG24N9K4 　　 DBW20B1-5X/200-6EG24N9K4 　　 DBW20B1-5X/315-6EG24N9K4 　　柱塞泵 A10VSO18DFR1/31R-PPA12N00 　　 A10VSO28DFR1/31R-PPA12N00 　　 A10VSO45DFR1/31R-PPA12N00 　　 A10VSO71DFR1/31R-PPA12N00 　　 A10VSO71DFR1/31R-PPA12N00 　　 A10VSO71DFR1/32R-VPB22U99 　　 A10VSO100DFR1/32R-PPB12N00 　　 A10VSO140DFR1/31R-PPB12N00 　　 A10VSO140DRS/32R-VPB12N00 　　 A10VSO28DR/31R-PPA12N00 　　 A10VSO45DR/31R-PPA12N00 　　 A10VSO71DR/31R-PPA12N00 　　 A10VSO100DR/31R-PPA12N00 　　 A10VSO140DR/31R-PPB12N00 　　内啮合泵 PGH3-2X/016RE07VU2 　　 PGH4-2X/025RE11VU2 　　比例阀 4WRKE16E-125L3X/6EG24EK31/A1D3M 　 4WRKE16E-200L3X/6EG24EK31/A1D3M 　　 4WRKE25E350L3X/6EG24EK31/A1D3M 　　 4WRKE25E500L3X/6EG24EK31/A1D3M 　　 4WREE10E50-2X/G24K31/A1V 　　 4WREE10E75-2X/G24K31/A1V 　　 4WREE6E04-2X/G24K31A1V 　　 4WREE6E08-2X/G24K31A1V 　　 4WREE6E16-2X/G24K31A1V 　　 4WREE6E32-2X/G24K31A1V 　　特价供应力士乐现货液压产品 　　4WE6D62/EG24N9K4 　　4WE6Y62/EG24N9K4 　　4WE6C62/EG24N9K4 　　4WE6A62/EG24N9K4 　　4WE6B62/EG24N9K4 　　4WE6J62/EG24N9K4 　　4WE6E62/EG24N9K4 　　4WE6M62/EG24N9K4 　　4WE6H62/EG24N9K4 　　4WE6HA62/EG24N9K4 　　4WE6G62/EG24N9K4 　　4WE6U62/EG24N9K4 　　4WE6L62/EG24N9K4 　　4WE10Y33/CG24N9K4 　　4WE10D33/CG24N9K4 　　4WE10C33/CG24N9K4 　　4WE10L33/CG24N9K4 　　4WE10U33/CG24N9K4 　　4WE10J33/CG24N9K4 　　4WE10E33/CG24N9K4 　　4WE10G33/CG24N9K4 　　4WE10H33/CG24N9K4 　　4WE6D62/EW230N9K4 　　4WE6Y62/EW230N9K4 　　4WE6J62/EW230N9K4 　　4WE6E62/EW230N9K4 　　4WE6G62/EW230N9K4 ，P与O口间的节流作用造成P口压力增高。随后P口与A口间的单向阀打开，经节流口向蓄能器供液。当蓄能器压力达到上限时，作用在 导阀右端单向阀阀芯3的液压力大于左端弹簧压力，下限单向阀6打开，上限单向阀3关闭，主阀右腔经 导阀于T口相通泄压，在左端压力作用下克服右端弹簧压力右移，P口与A口间的单向阀关闭，恢复全流量向下游系统供液，充液过程结束。VT-VPPA1-500-20/VO VT-3000 S35 R5 VT-3000 S35 R5 VT-3000 S35 R5 0811405041VT-SSPA1-525-10/VO 0811405060VT-VRRA1-527-20/VO 0811405061VT-VRRA1-537-20/VO 0811405062VT-VRPA1-537-10/VO 0811405063 VT-VRPA1-527-20/VO/2S1V 0811405064VT-VRPA1-527-20/VO/PO-4S 0811405065VT-VRRA1-527-20/VO/K40-AGC 0811405066VT-VRRA1-527-20/VO/K60-AGC 0811405067VT-VRRA1-537-20/VO/K40-AGC 0811405068VT-VRRA1-527-20/VO/K40-AGC-2STV 0811405069VT-VRRA1-52/-20/VO/KV-AGC 0811405070VT-VRRA1-53/-20/VO/KV-AGC 0811405071VT-VIB01-5-1X/VO/0 0811405073VT-VRPA1-527-20/VO/RIS-2STV 0811405074VT-VRPAI-527-20/VO/RIS-2/2V 0811405075VT-VARAI-500-10/VO/VLRC 0811405076VT-VRPA1-527-20/VO/2/2V 0811405079VT-VSPA1-525-10/VO/RIP 0811405080VT-VSPA2-525-10/VO/RIP 0811405081VT-VSPA1-508-10/VO/RIP 0811405082VT-KRRA2-537-20/VO/ 0811405083VT-KRRA2-527-20/V0/2CH 0811405084VT-VARAP1-527-10/V0 0811405085 VT-VARAP1-537-10/V0 0811405086VT-VARAP1-537-10/V0/5/3V 0811405087VT-VARAP1-527-10/V0/2S1V 0811405088VT-VARAP1-527-10/V0/3/2VAX 0811405093SETVAL+SIG CONV 0811405094 SETVAL+SIG CONV 0811405095VT-VRPA1-527-10/V0 0811405096VT-VRPA1-527-10/V0/PV 0811405097VT-VRPA1-537-10/V0/PV 0811405098VT-VRPA1-527-10/V0/QV 0811405099VT-VRPA1-537-10/V0/QV 0811405100VT-VRPA1-527-10/V0/RTP 0811405101VT-VRPA1-527-10/V0/PV-RTP 0811405102VT-VRPA1-537-10/V0/PV-RTP 0811405103VT-VRPA1-527-10/V0/QV-RTP 0811405104VT-VRPA1-537-10/V0/QV-RTP 0811405105VT-SWMA1-5-1X/V0/0 0811405106VT-MSPA2-525-10/V0 0811405107VT-SWMA2-5-1X/V0/0 0811405108VT-SWMA3-5-1X/V0/0 0811405109VT-MNE1-5-1X/V0/0 0811405111VT-BNE1-5-1X/V0/0 0811405115VT-VACAS-500-10/V0/LVAR 0811405116SETVAL+SIG CONV 0811405119VT-VRPA2-527-10/V0/RTP 0811405120VT-VRPA2-537-10/V0/RTP 0811405121VT-SWMA4-5-1X/V0/0 0811405122VT-MARAM-537-10/V0/X2 0811405123VT-VRRA1-527-10/V0 0811405124VT-VACAP-500-10/V0 0811405126VT-MSPA1-508-10/V0 0811405127VT-MSPA1-525-10/V0 0811405128VT-VACAI-500-10/V0/VLRD 0811405129VT-VACDS-500-10/V0/DM 0811405130
