Rexroth力士乐3DR10P4-6X/200Y/00M三通减压阀3DR型压力阀是一种先导式三通减压阀，可限制次级油路的压力。用于降低系统压力。此类减压阀主要由带控制阀芯(2)的主阀(1)以及带压力调节元件(10)的先导控制阀(3)组成。在初始位置时阀门处于打开状态。液压油可以不受限制地从通道P流向通道A。同时，通道A中的压力通过孔(4)作用于与压缩弹簧(9)相对的柱塞表面。同时，该压力通过喷嘴(6)施加于控制阀芯(2)的弹簧负载侧，并通过通道(5)施加于先导控制阀(3)中的滚珠(7)。根据压缩弹簧(11)的设置，压力在滚珠(7)上游以及通道(5)中增加，使控制阀芯(2)保持在开启位置。液压油可从通道P经控制阀芯(2)流向通道A，直到通道A中的压力增加到超过压缩弹簧(11)处设置的压力值，并打开滚珠(7)。控制阀芯(2)移动到闭合位置。如果通道A中的压力与压缩弹簧(11)处设置的压力值之间处于一种平衡状态，便实现了所需的减压。当通道A中的压力因作用于执行机构的外力而继续增加时，控制阀芯(2)将继续相对压缩弹簧(9)移动。这样，通道A将经由控制阀芯(2)上的控制边(8)与通道T相连接。这样一来，大量液压油将流回油箱，以使压力不再增加。来自弹簧腔(12)的先导油回油始终通过油口Y处的控制油路(13)外部实现。此时必须始终确保与油箱的连接处于已卸压状态。压力计连接(14)可实现对通道A中减压的控制。R9009166573DR10P4-6X/100Y/00MR9009177953DR10P4-6X/100Y/00VR9009177873DR10P4-6X/200Y/00MR9009177973DR10P4-6X/200Y/00VR9009177913DR10P4-6X/315Y/00MR9009177903DR10P4-6X/315Y/00VR9009323243DR10P4-6X/50Y/00MR9009177863DR10P5-6X/100Y/00VR9009177883DR10P5-6X/200Y/00VR9009166613DR10P5-6X/315Y/00MR9009177943DR10P5-6X/315Y/00VR9009738733DR10P5-6X/50Y/00VR9009177933DR10P6-6X/100Y/00VR9009177923DR10P6-6X/200Y/00MR9009177853DR10P6-6X/200Y/00VR9009177843DR10P6-6X/315Y/00MR9010152523DR10P6-6X/50Y/00MR9009177963DR10P7-6X/100Y/00MR9010683953DR10P7-6X/100Y/00VR9007373663DR10P7-6X/200Y/00MR9010308613DR10P7-6X/200Y/00VR9011493193DR10P7-6X/315Y/00MR9009177823DR16P4-5X/100Y/00MR9009177803DR16P4-5X/100Y/00VR9009166673DR16P4-5X/200Y/00MR9009177723DR16P4-5X/200Y/00VR9009177813DR16P4-5X/250Y/00MR9009760273DR16P4-5X/50Y/00MR9009177743DR16P5-5X/100Y/00VR9009177733DR16P5-5X/200Y/00VR9009177753DR16P5-5X/250Y/00MR9009166703DR16P5-5X/250Y/00VR9013575413DR16P5-5X/50-15Y/00MR9009420903DR16P5-5X/50Y/00VR9009177773DR16P6-5X/100Y/00MR9009177793DR16P6-5X/100Y/00VR9009166693DR16P6-5X/200Y/00MR9009177833DR16P6-5X/200Y/00VR9009177783DR16P6-5X/250Y/00MR9012345213DR16P7-5X/100Y/00MR9009505743DR16P7-5X/200Y/00MR9012445233DR16P7-5X/250Y/00MA2FO10/61L-VBB06A2FO10/61L-VPC56*SV*A2FO10/61R-NPC56*SV*A2FO10/61R-NSC56*SV*A2FO10/61R-PPB06A2FO10/61R-PZB06A2FO10/61R-VAB06A2FO10/61R-VPB06A2FO10/61R-VPC56*SV*A2FO107/61L-VBD55*AL*A2FO107/61L-VSD55A2FO107/61L-VSD55*AL*A2FO107/61R-NBD55A2FO107/61R-PPB05*SV*A2FO107/61R-VPB05*SV*A2FO107/61R-VSD55*SV*A2FO12/61L-PPP06*SV*A2FO12/61L-PZB06A2FO12/61L-PZP06*AL*A2FO12/61L-VPB06A2FO12/61R-NBC56*SV*A2FO12/61R-PBB06A2FO12/61R-PPB06A2FO12/61R-PZB06A2FO12/61R-VPB06A2FO125/61L-NBD55*AL*A2FO125/61R-NBD55*AL*A2FO125/61R-PAB05*SV*A2FO125/61R-VAB05*SV*A2FO125/61R-VBB05*SV*A2FO16/61L-NSC56A2FO16/61L-NSC56-EA2FO16/61L-PAB06A2FO16/61L-PAB06-EA2FO16/61L-VAB06A2FO16/61L-VSC56A2FO16/61R-NBC56*SV*A2FO16/61R-NSC56A2FO16/61R-PBB06A2FO16/61R-VAB06A2FO16/61R-VBB06A2FO16/61R-VBC56*SV*A2FO16/61R-VSC56A2FO16/61R-VSC56-EA2FO160/61L-VZB05A2FO160/61R-NBD55*SV*A2FO160/61R-PAB05A2FO160/61R-PPB05A2FO160/61R-VBB05A2FO160/61R-VBD55A2FO160/61R-VBD55-EA2FO180/61R-VBB05A2FO180/61R-VBD55*SV*A2FO200/63R-NBB05A2FO23/61L-NSD55*SV*A2FO23/61L-PPB05A2FO23/61L-PZB06*AL*A2FO23/61L-VBD55*SV*A2FO23/61L-VPB06*SV*A2FO23/61L-VPP06*SV*A2FO23/61R-NBD55*SV*A2FO23/61R-PAB06A2FO23/61R-PPB05A2FO23/61R-PPB06*AL*A2FO23/61R-PZB06A2FO23/61R-VBB05A2FO23/61R-VBB06*AL*A2FO23/61R-VBD55*SV*A2FO23/61R-VPB06*SV*A2FO23/61R-VPP06*SV*A2FO23/61R-VSD55A2FO250/60R-VKD55A2FO250/60R-VPB05A2FO250/60R-VSD55A2FO250/60R-VZB05A2FO28/61L-NBD55*SV*A2FO28/61L-PAB05A2FO28/61L-PPB05A2FO28/61R-NBD55*SV*A2FO28/61R-NSD55*SV*A2FO28/61R-PBB05A2FO28/61R-PPB05A2FO28/61R-PPB06A2FO28/61R-VBD55*SV*A2FO28/61R-VPB05A2FO28/61R-VPB06A2FO28/61R-VSD55A2FO28/61R-VZB05A2FO32/61L-NBD55*SV*A2FO32/61L-VAB05A2FO32/61L-VBB05A2FO32/61L-VSD55*SV*A2FO32/61R-NSD55A2FO32/61R-PBB05A2FO32/61R-PBB06*AL*A2FO32/61R-VBB05A2FO32/61R-VBD55*SV*A2FO32/61R-VSD55*SV*A2FO355/60R-VPH11A2FO45/61L-NPD55*SV*A2FO45/61L-NSD55A2FO45/61L-VPD55*SV*A2FO45/61R-NPD55*SV*A2FO45/61R-NSD05-S*SV*A2FO45/61R-NSD55*SV*A2FO45/61R-PPB05A2FO45/61R-PZB05A2FO45/61R-VPB05A2FO45/61R-VPD550A2FO45/61R-VSD55A2FO500/60L-VPH11A2FO500/60L-VZH11A2FO500/60R-VPH11A2FO500/60R-VZH11A2FO500/60R-VZH11-SO120A2FO56/61R-NTD55A2FO56/61R-PPB05A2FO56/61R-VPB05A2FO63/61L-NSD55*SV*A2FO63/61L-VBB05A2FO63/61L-VSD55*SV*A2FO63/61R-NBD55A2FO63/61R-NSD55A2FO63/61R-PAB05A2FO63/61R-VBB05A2FO63/61R-VBD55A2FO80/61L-VQDN55*SV*A2FO80/61R-PPB05*SV*A2FO80/61R-VBB05*AL*A2FO80/61R-VPB05*SV*A2FO80/61R-VQDN55-E*AL*A2FO90/61R-PBB05*SV*A2FO90/61R-VBB05*AL*A2FO90/61R-VQDN55*AL*A2FO90/61R-VUDN55A4FO125/10X-PZB25N00A4FO250/10X-PPB13N00A4FO250/30R-VPB25N00A4FO500/10R-PPH25K34)
