調(diào)節(jié)閥的安裝，必須確保安全性，確保使用性能，易于操作和維護(hù)，節(jié)約安裝費(fèi)用。下面就針對(duì)這四點(diǎn)談一談安裝時(shí)需要注意的具體問題。1)防止泄漏安裝過程不允許調(diào)節(jié)閥產(chǎn)生泄漏。在使用過程中，如果在填料涵、法蘭墊片等部位形成縫隙或微孔就可能產(chǎn)生泄漏。如果流體介質(zhì)的操作條件苛刻，T型過濾器比如高溫、高壓、流體有腐蝕性，那么損壞將加劇，泄漏的危險(xiǎn)性就更大。防止泄漏的方法很多，在安裝過程中，填料的選擇、密封方法的選擇、選用密封性能好的調(diào)節(jié)閥等，都是必須考慮的因素。2)安裝放泄閥任何一個(gè)管路設(shè)計(jì)和安裝，在切斷時(shí)都不可避免地積有高壓流體，如果積聚流體的潛在能量很大，應(yīng)在調(diào)節(jié)閥的兩側(cè)安裝放泄閥，這樣，在系統(tǒng)切斷之后，調(diào)節(jié)閥中殘留的高壓流體的能量能得到釋放，保護(hù)人員安全，有利于調(diào)節(jié)閥的維修，也可以考慮選用能限制流量的放泄閥。3)安全的管線在安裝調(diào)節(jié)閥前，全部安裝管件和管線都要吹掃干凈，因?yàn)楣芫€中的砂粒、水垢、鐵屑等會(huì)損壞調(diào)節(jié)閥內(nèi)表面，尤其是要求嚴(yán)格的密封面。當(dāng)系統(tǒng)壓力波動(dòng)嚴(yán)重時(shí)，建議在管線上安裝緩沖設(shè)施。如果被排放的流體是有害氣體或液體，那么排放流體用的管線必須連接到安全地點(diǎn)，也可以連接到安全的特定容器中。

液壓機(jī)閥的基本結(jié)構(gòu)和工作原理包括閥芯、閥體和驅(qū)動(dòng)閥芯在閥體內(nèi)作相對(duì)運(yùn)動(dòng)的裝置，其中驅(qū)動(dòng)裝置有手調(diào)機(jī)構(gòu)、彈簧或電磁鐵、液壓力。普通錐閥類的閥芯與閥體之間采用的是線性密封，密封效果較好，可靠性較高.而采用滑閥結(jié)構(gòu)的控制閥的閥芯與閥休之間存在相對(duì)位置的滑動(dòng)，因此閥芯與閣體孔之間采用的是間隙配合。根據(jù)流體力學(xué)縫隙流動(dòng)公式可知，在工作壓差一定時(shí)，閥芯與閥體孔的配合間陳越小則閥體的密封性能越好，內(nèi)泄星也就越小，提高系統(tǒng)效率減少油液發(fā)熱長.但配合間隙過小，會(huì)使閥芯動(dòng)作不靈敏，甚至使閥芯卡死.因此，為確?；y的密封性同時(shí)確保閥工作的可靠性般取閥芯與閥體孔之間的半徑間隙在。液壓機(jī)中的液壓閥常見的閥芯故障，液壓閥閥芯故障可分為兩類:閥芯密封不嚴(yán)有內(nèi)泄、閥芯動(dòng)作異常。1、閥芯密封不嚴(yán)有內(nèi)泄，多出在錐閥形式的閥上。當(dāng)閥芯關(guān)閉控制口時(shí)，由于閥芯與閥座接觸不緊密或彈簧斷裂等，不能將液流完全封閉而產(chǎn)生泄漏。2、閥芯動(dòng)作不到位、不靈敏或無動(dòng)作，在滑閥機(jī)構(gòu)中由于閥芯與閥體采用的是間隙配合，加下精度要求很高。因此閥的工作性能很容易受到自身與外界因素的干擾。英格索蘭
