直銷阿托斯ATOS溢流閥/ATOS比例閥 ATOS先導(dǎo)型溢流閥由主閥和先導(dǎo)閥兩部分組成。先導(dǎo)閥類似于直動型溢流閥，但一般多為錐閥（或球閥）形閥座式結(jié)構(gòu)。主閥可分為一節(jié)同心結(jié)構(gòu)、二節(jié)同心結(jié)構(gòu)和三節(jié)同心結(jié)構(gòu)。三節(jié)同心結(jié)構(gòu):主閥芯與閥蓋、閥體與主閥座等三處有同心配合要求，屬于三節(jié)同心結(jié)構(gòu)。壓力油自閥體中部進(jìn)油口進(jìn)入，并主閥芯上阻尼孔進(jìn)入主閥芯上腔，油閥蓋上通道和錐閥座上小孔作用與錐閥上。當(dāng)進(jìn)油口壓力小于先導(dǎo)閥調(diào)壓彈簧調(diào)定值時，先導(dǎo)閥關(guān)閉，主閥芯上、下兩側(cè)有效面積比為1.03～1.05，上側(cè)稍大，作用與主閥芯上壓力差和主閥彈簧力均使主閥口閉緊，不溢流。當(dāng)進(jìn)油壓力超過先導(dǎo)閥調(diào)定壓力時，先導(dǎo)閥被打開，造成資金油口P井主閥芯阻尼孔、先導(dǎo)閥口、主閥芯中心孔至閥體下部出油口（溢流口）流動。阻尼孔處流動損失使主閥芯上、下腔中油液產(chǎn)生一個隨先導(dǎo)閥流量增加而增加壓力差，當(dāng)它主閥芯上、下作用面上產(chǎn)生總壓力差足以克服主閥彈簧力、主閥自重和摩擦力時，主閥芯開啟。此時進(jìn)油口與出油口（溢流口）直接相通，造成溢流以保持系統(tǒng)壓力。 ATOS先導(dǎo)型溢流閥故障失靈及造成的原因：先導(dǎo)閥閥芯彈簧折斷；陰尼孔堵塞；先導(dǎo)閥閥口密封不良；主閥芯卡死等。相應(yīng)的排除措施是：更換或在折斷處加平墊以應(yīng)急使用；清洗疏通；研磨或?qū)⒃撚吐窋嗦芬詰?yīng)急使用；研磨、清洗。 限壓不穩(wěn)：先導(dǎo)型溢流閥限壓不穩(wěn)，表現(xiàn)為液壓系統(tǒng)壓力偏低或偏高，液壓執(zhí)行元件動作無力或油管、泵體、閥體爆裂。造成限壓不穩(wěn)故障的原因：壓力調(diào)整不當(dāng)；先導(dǎo)閥閥芯彈簧彎曲或變軟；油液過臟或油液流動不暢。相應(yīng)的排除措施是：重新調(diào)整；校正、加墊或更換；更換、清洗。先導(dǎo)型溢流閥限壓不穩(wěn)為漸發(fā)性故障，先導(dǎo)型溢流閥失靈為突發(fā)性故障，在排除完故障后，應(yīng)按系統(tǒng)所限定的壓力對先導(dǎo)型溢流閥控制的壓力重新進(jìn)行調(diào)整。 我司是各*供應(yīng)商，產(chǎn)品廣泛用于各行業(yè)，我司常年備有大量庫存 ，快速報(bào)價(jià)。為客戶提供*價(jià)格，zui快捷貨期、zui滿意服務(wù)，：劉浪 （）：：傳真（）： 1539908756 公司地址：廣東省東莞市南城區(qū)宏遠(yuǎn)路一號宏遠(yuǎn)大廈13A11室 ATOS先導(dǎo)式溢流閥 AGAM-10/350 AGAM-10/50 34 AGAM-20/10/100/V-IX 24DC 53 AGAM-20/10/210/V-IX 24DC 53 AGAM-20/10/210-IX 230/50/60AC AGAM-20/10/210-IX 24DC AGAM-20/10/350-IX 230/50/60AC AGAM-20/10/350-IX 24DC AGAM-20/100 AGAM-20/11/210/M-AO 220 21 AGAM-20/11/210/V-IX 24DC 53 AGAM-20/11/210-IX 230/50/60AC AGAM-20/11/210-IX 24DC AGAM-20/11/350-IX 24DC 53 AGAM-20/210 AGAM-20/210/V 53 /WG AGAM-20/22/350/350-IX 24DC AGAM-20/350 AGAM-32/10/210-IX 24DC AGAM-32/10/350-IX 24DC AGAM-32/20/210/210/V-IX 230/50/60AC 53 AGAM-32/20/210/210-IX 230/50/60AC AGAM-32/20/350/210-IX 24DC 53 AGAM-32/210 53 AGAM-32/350 AGAM-32/350/V 53 ARAM-20/10/100/V-IX 110/50/60A ARAM-20/10/210-IX 24DC 72 ARAM-20/100 72 ARAM-20/210 ARAM-20/350 72 ARAM-32/11/210-IX 110/50/60AC AGAM-10/10/100 34 AGAM-10/10/100-IX 230/50/60AC 34 AGAM-10/10/100-IX 24DC AGAM-10/10/210 直銷阿托斯ATOS溢流閥/ATOS比例閥 AGAM-10/10/210/V-IX 24DC AGAM-10/10/210-IX 230/50/60AC AGAM-10/10/210-IX 24DC AGAM-10/10/210-IX 24DC 34/WG AGAM-10/10/350 34 AGAM-10/10/350/V-IX 24DC AGAM-10/10/350-1X 24DC 34 AGAM-10/100 AGAM-10/100/V AGAM-10/11/100 34 AGAM-10/11/100/7PA-M-AO 24DC AGAM-10/11/100-IX 230/50/60AC AGAM-10/11/210-IX 230/50/60AC AGAM-10/11/210-IX 24DC AGAM-10/11/350/PA-GK-AO 24DC 22 AGAM-10/11/350-IX 110/50/60AC AGAM-10/11/350-IX 24DC AGAM-10/20/210/100-IX 24DC AGAM-10/20/350/100-IX 230/50/60AC 34 AGAM-10/20/350/210/V-IX 230/50/60AC 34 AGAM-10/20/350/210-IX 230/50/60AC 34 AGAM-10/20/350/210-IX 24DC 34 AGAM-10/21/350/100-IX 24DC 34 AGAM-10/21/350/210-IX 230/50/60AC 34 AGAM-10/210 AGAM-10/210/V 34 ATOS放大器 E-BM-AC-011F E-BM-AC-01F 11/2 E-BM-AC-01F 11/3 E-BM-AC-01F/RR 11/A1 E-BM-AC-05F 11/3 E-BM-AC-05F 11/4 E-BM-AC-05F/RR 11/3 E-ME-AC-01F 20 E-ME-AC-01F 20/1 E-ME-AC-01F 20/2 E-ME-AC-01F 20/3 E-ME-AC-01F 20/4 E-ME-AC-01F 20/6 E-ME-AC-01F 20/A1 E-ME-AC-01F 20/A2 E-ME-AC-01F 20/A4 E-ME-AC-01F/4R-4 20 E-ME-AC-01F/4R-4 20/2 E-ME-AC-01F/4R-4 20/3 E-ME-AC-01F/4R-4 20/6 E-ME-AC-01F/I 20 E-ME-AC-01F/I 20/2 E-ME-AC-01F/I 20/4 E-ME-AC-01F/I 20/6 E-ME-AC-01F/RR 20/4 E-ME-AC-01F/RR 20/A2 E-ME-AC-01F/RR-4 20 E-ME-AC-01F/RR-4 20/3 E-ME-AC-01F/RR-4 20/6 E-ME-AC-01F-4 20/2 E-ME-AC-05F 20 E-ME-AC-05F 20/2 E-ME-AC-05F 20/3 E-ME-AC-05F 20/4 E-ME-AC-05F 20/A3 E-ME-AC-05F/4R-4 20/3 E-ME-AC-05F/4R-4 20/4 E-ME-AC-05F/I 20 E-ME-AC-05F/I 20/3 E-ME-AC-05F/I 20/4 直銷阿托斯ATOS溢流閥/ATOS比例閥 |
