詳細(xì)內(nèi)容： 節(jié)流閥前、后的壓力分別引到減壓閥閥芯右、左兩端，當(dāng)負(fù)載壓力增大，于是作用在減壓閥芯左端的液壓力增大，閥芯右移，減壓口加大，壓降減小，從而使節(jié)流閥的壓差(p2-p3)保持不變;反之亦然。這樣就是調(diào)速閥的流量恒定不變(不受負(fù)載影響)。 聯(lián)系人：蔡韻17771783950 手機(jī)：一八七七一零二二八二九 手機(jī)：17771783950/18771022829 qq3121226951/1287946729 電話：027-8816919001HF/L252H E-ME-AC-05F/1 E-ME-AC-05F/3 E-ME-AC-05F/4 E-ME- PVB6-RSY-40-CC-12 PVB6-RSY-40-CM-12-S30 PVE012R01AUB0A2100000200100CD0A PVE012R01AUB0B2111000100100CD0A PVE012R05AUB0A2100000100100CD0A PVE012R01AUB0A2100000100100CD0A PVE012R05AUB0D0100000100100CD0A PVE012R01AUB0B211100A100100CD0A PVQ20-B2R-A9-SS1S-21-CM7-12SCE215C010 SCE215C020 SCE215C030 SCE215C053 SCE215C053 SCE215C063 SCE215C063 SCE215C063VH SCE215C063VM SCE215C073 SCE215C073 SCE215C073VH SCE215C073VM SCE215C083 ASCO 18900001 ASCO 35500382 ASCO SC8551A005MS ASCO 8551A017 MS ASCO MP-C-086 ASCO EF8320G186 ASCO ER90A016 ASCO 57000103 ASCO 57000104 ASCO 302329 ASCO SCB210DB9BN ASCO 52100005 ASCO 400425-117J PVQ20-B2R-A9-SS1S-21-C21V11B-13 PVQ20-B2R-A9-SS1S-21-C21-12 PVQ20-B2L-SE1S-21-CM7-12 PVQ20-B2L-SE1S-21-C21D-12 PVQ20-B2L-SE1S-21-C21-12 PVQ20-B2R-SS1S-21-CM7-12 PVQ20-B2R-SE1S-21-C21-12 PVQ20-B2R-SE1S-21-C21D-12 PVQ20-B2R-SE1S-21-C21D-12-S2 PVQ20-B2R-SE1S-21-C21V11B-13 PVQ20-B2R-SE1S-21-CM7-12 PVQ20-B2R-SE3S-21-C21-12 PVQ20-B2R-SS1S-21-CD21D-21 PVQ20-B2R-SE1S-21-CM7D-12 PVQ20-B2R-SS1S-21-C21-12 PVQ20-B2R-SS3S-21-C21-12 PVQ20-B2R-SE1S-21-CG-30
