</p><p> 1、調(diào)節(jié)閥的安裝調(diào)節(jié)閥的安裝應(yīng)遵循國(guó)家有關(guān)標(biāo)準(zhǔn)，按照設(shè)計(jì)圖紙和設(shè)計(jì)文件的規(guī)定嚴(yán)格執(zhí)行。例如，建筑安裝工程質(zhì)量檢驗(yàn)評(píng)定標(biāo)準(zhǔn)、工業(yè)自動(dòng)化儀表施工及驗(yàn)收規(guī)范、電氣設(shè)備安裝工程施工及驗(yàn)收規(guī)范等;安裝所需的設(shè)備、輔助設(shè)備及主要材料應(yīng)符合現(xiàn)行國(guó)家標(biāo)準(zhǔn)的有關(guān)規(guī)定。調(diào)節(jié)閥及附件從出廠到安裝前，在運(yùn)輸途中受到運(yùn)輸工具所激發(fā)的隨機(jī)振動(dòng)和裝卸時(shí)受到的各種沖擊，以及在運(yùn)輸和儲(chǔ)存過程中，環(huán)境的溫度、濕度等變化，這些都可能造成調(diào)節(jié)閥及附件的性能發(fā)生變化。因此，有必要在安裝前進(jìn)行部分性能的檢驗(yàn)。調(diào)節(jié)閥安裝前的檢驗(yàn)主要包括下列內(nèi)容：外觀、靜態(tài)特性、泄漏量、空載全行程時(shí)間、耐壓強(qiáng)度、絕緣性能、氣密性和密封性等，其中前5項(xiàng)為必檢項(xiàng)目。當(dāng)然，對(duì)檢驗(yàn)的場(chǎng)所也有一定的要求。例如：環(huán)境溫度要求在10～35℃;空氣相對(duì)濕度不大于75%;場(chǎng)地有足夠的空間，且光線充足或有照明條件;周圍不能有劇烈的振源和強(qiáng)磁場(chǎng)干擾;電源、氣源符合要求等。英格索蘭

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。復(fù)盛

調(diào)節(jié)閥輸出信號(hào)是閥位信號(hào)，可以是模擬量信號(hào)或數(shù)字量信號(hào)。應(yīng)在檢查調(diào)節(jié)閥輸入信號(hào)的同時(shí)，檢查閥位信號(hào)是否正確。采用HART或智能電氣閥門定位器時(shí)，應(yīng)檢查閥位狀態(tài)信息能否正確傳輸。調(diào)節(jié)閥全行程運(yùn)行過程中應(yīng)注意閥芯和閥座是否有機(jī)械振動(dòng)和異常噪音。 </p> <p> 3)手輪機(jī)構(gòu)調(diào)試 </p> <p> 檢查手輪機(jī)構(gòu)能否正確轉(zhuǎn)動(dòng)和動(dòng)作，限位和鎖定裝置是否好用。 </p> <p> 4)當(dāng)出現(xiàn)偏差超過允許偏差極限時(shí)，應(yīng)進(jìn)行相應(yīng)的調(diào)試。例如，改變閥位開關(guān)的位置，檢查接線或管路是否有泄漏等。浙江閥芯材料</p><p
