安裝調(diào)節(jié)閥時(shí)，要盡量保證其性能不受影響。這種影響會(huì)破壞調(diào)節(jié)閥選擇時(shí)所考慮的各種因素。1)調(diào)節(jié)閥上、下游切斷閥和旁路閥的安裝上、下游切斷閥與調(diào)節(jié)閥之間的直管段長度應(yīng)考慮管路阻力和對流體流動(dòng)狀態(tài)的影響。直管段長度長，有利于流體經(jīng)切斷閥后的穩(wěn)定，可使流體流動(dòng)平穩(wěn)，減少紊流影響，降低噪聲;直管段長度短，流體經(jīng)切斷閥后還未穩(wěn)定就進(jìn)入調(diào)節(jié)閥，使噪聲增大，但直管段長度短有利于降低管路阻力，提高調(diào)節(jié)閥兩端壓降，使流量特性的畸變減小，有利于控制系統(tǒng)的穩(wěn)定運(yùn)行。因此，應(yīng)權(quán)衡利弊，綜合考慮。按照經(jīng)驗(yàn)，通常上游側(cè)應(yīng)有10D～**的直管段，下游側(cè)有3D～5D的直管段(D為管道直徑)，必要時(shí)應(yīng)設(shè)置整流裝置。調(diào)節(jié)閥拆卸維修時(shí)，可用旁路閥對生產(chǎn)過程進(jìn)行操作。當(dāng)被控流量過大，用調(diào)節(jié)閥無法正常調(diào)節(jié)時(shí)，作為應(yīng)急措施，也可用旁路閥作為調(diào)節(jié)閥的并行連接方案，對過程進(jìn)行控制。為降低成本，大口徑調(diào)節(jié)閥安裝手輪執(zhí)行機(jī)構(gòu)，可代替旁路閥進(jìn)行操作。旁路閥的安裝應(yīng)便于操作，它與調(diào)節(jié)閥及上，浙江Wartsilar瓦錫蘭柴油機(jī)閥芯、下游切斷閥一起組成調(diào)節(jié)閥組。因此，安裝調(diào)節(jié)閥時(shí)應(yīng)與切斷閥和旁路閥配套考慮，并同時(shí)完成施工安裝，浙江Wartsilar瓦錫蘭柴油機(jī)閥芯，浙江Wartsilar瓦錫蘭柴油機(jī)閥芯。旁路閥公稱直徑與管道公稱直徑相同，耐壓等級也與工藝耐壓等級一致。

2)泄放閥、放空閥、排污閥的安裝為便于調(diào)節(jié)閥拆卸，在拆卸前必須進(jìn)行閥前和閥后壓力的泄放，泄放閥應(yīng)安裝在調(diào)節(jié)閥與上、下游切斷閥之間。放空閥和排污閥用于排放流體中夾帶的不凝氣體和冷凝液，假若安裝時(shí)被控流體是氣體或蒸汽時(shí)，為便于冷凝液的排放，排污閥宜安裝在調(diào)節(jié)閥組的較低處;而被控流體是液體時(shí)，為便于不凝氣體的排放，放空閥宜安裝在調(diào)節(jié)閥組的較高處。3)調(diào)節(jié)閥與管道的連接調(diào)節(jié)閥與管道的連接方式有螺紋連接、法蘭連接和焊接連接等區(qū)別。螺紋連接方式用于小口徑調(diào)節(jié)閥的安裝，必須同時(shí)安裝可拆卸的活動(dòng)連接件;法蘭連接方式有普通式法蘭連接和夾持式連接兩種，管道連接法蘭的公稱直徑應(yīng)與調(diào)節(jié)閥的通徑一致，封頭耐壓等級也應(yīng)與調(diào)節(jié)閥的耐壓等級一致，法蘭面與管道軸線的垂直度允許偏差為l°;盡量避免采用焊接連接方式。調(diào)節(jié)閥連接時(shí)，不應(yīng)使連接管道內(nèi)部出現(xiàn)新的凸出物，例如，密封墊、焊接縫等不應(yīng)在管道內(nèi)凸出。同時(shí)，應(yīng)注意調(diào)節(jié)閥內(nèi)流體的流向應(yīng)與閥體上標(biāo)注的箭頭方向一致，特殊情況下可不受此限制。

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，可以采用錐形臺肩，臺肩小端朝向高壓區(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)對于組合式換向閥，為了消除閥片間結(jié)合面平面度對卡緊的影響，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。英格索蘭
