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。

2、避免卡緊現(xiàn)象的措施1)滑閥的液壓卡緊是共性問題，不僅換向閥有，其他液壓閥也存在，故傳統(tǒng)設(shè)計(jì)中都有避免卡緊的措施，嚴(yán)格控制閥芯、閥孔的制造精度，一般，閥芯和閥孔的圓柱度允差為μm，表面粗糙度：閥芯為，閥孔為，兩者配合間隙為～μm，并在閥芯的適當(dāng)位置(靠近高壓區(qū)側(cè))上開設(shè)環(huán)形槽，寬～1mm，深約，且環(huán)形槽要與外圓保證同心。2)閥芯的精度允許時(shí)，可以磨順錐(即小端朝向高壓區(qū))，結(jié)構(gòu)允許的情況下，可以采用錐形臺(tái)肩，臺(tái)肩小端朝向高壓區(qū)，有利于閥桿徑向?qū)χ小?)仔細(xì)消除芯上各臺(tái)肩及閥孔沉割槽邊上的毛刺。仔細(xì)消除熱處理件的氧化皮，且在轉(zhuǎn)序時(shí)利用工位器具防止零件磕碰。4)裝配過程中要防止零件磕碰，要注意清潔，各螺栓的預(yù)緊力要適當(dāng)，以防閥孔變形。5)要保證液壓系統(tǒng)的清潔度，防止油液被污染。6)提高閥體的鑄造質(zhì)量，減少閥芯的熱處理殘余應(yīng)力，防止彎曲變形。7)對(duì)于組合式換向閥，為了消除閥片間結(jié)合面平面度對(duì)卡緊的影響，可使其中一個(gè)面的中間部分低1～2μm，這既可減少閥孔的變形，又不致影響結(jié)合面的密封。溫州復(fù)盛閥芯</p><p
