ATOS先導(dǎo)型溢流閥阿托斯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(dòng)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(dòng)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。 

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(dòng)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(shí)，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(shí)，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(dòng)。阻尼孔處流動(dòng)損失使主閥芯上、下腔中油液產(chǎn)生一個(gè)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(shí)，主閥芯開啟。此時(shí)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。

二節(jié)同心結(jié)構(gòu):主閥芯為帶有圓柱面錐閥。為使主閥關(guān)閉時(shí)有良好密封性，要求主閥芯1圓柱導(dǎo)向面和圓錐面與閥套配合良好，兩處同心度要求較高，故稱二節(jié)同心。主閥芯上沒有阻尼孔，而將三個(gè)阻尼孔分別設(shè)閥體和先導(dǎo)閥體上。其工作原理與三節(jié)同心先導(dǎo)型溢流閥相同，只油液從主閥下腔到主閥上腔，需三個(gè)阻尼孔。 

根據(jù)零件技術(shù)要求，進(jìn)行動(dòng)力和運(yùn)動(dòng)分析，再確定主要參數(shù)，液壓圖形編制，然后擬定液壓系統(tǒng)圖，進(jìn)行標(biāo)準(zhǔn)元件選擇和元件設(shè)計(jì)，之后驗(yàn)證液壓系統(tǒng)技術(shù)性能，zui后編制技術(shù)文件與審核。
