塵土多的場合要在閥桿周圍用塑料套或橡膠套保護填料函和導向部位，有腐蝕性氣體或液滴存在的場合要采用特殊的保護措施，一般用防腐袋包住調(diào)節(jié)閥，但要注意不能影響它的操作。在有耐火性要求的場合，可以采用特殊耐火涂料、套防火袋等方法，防火袋的材料含有多層陶瓷纖維或玻璃纖維。氣源是驅(qū)動氣動調(diào)節(jié)閥的關(guān)鍵能源之一。氣動調(diào)節(jié)閥的膜室雖然不消耗空氣，但如果氣源系統(tǒng)含有水分、油污等雜質(zhì)，則會使閥門定位器、繼動器等附件堵塞并發(fā)生故障。因此必須定期對氣源和電源進行檢查，保證氣源清潔、干燥，電源可靠。調(diào)節(jié)閥應(yīng)用**的支架固定，防止松動，要保證整體的垂直位置或水平位置。如果遠距離運輸，比較好用牢固的木箱裝運。調(diào)節(jié)閥在組裝和油漆并按要求裝上執(zhí)行機構(gòu)、手輪、定位器等附件以后，為防止外來物質(zhì)進入調(diào)節(jié)閥，連接調(diào)節(jié)閥的全部空氣接口都要堵上，連接法蘭裝上保護罩，要留意各個連接部位，例如閥門定位器進氣管、執(zhí)行機構(gòu)接口的狀態(tài)。易損壞的任何突出的附件，如注油器和電位器的壓力表，應(yīng)從接頭上拆下，與調(diào)節(jié)閥分開包裝并一同運輸。

條件允許時盡量選用硬密封。"O"型球閥硬密封可達10-5，三偏心蝶閥可達零泄漏。2)對密封耐磨性的考慮:除選硬密封外，對泄漏要求10-4以上的切斷型調(diào)節(jié)閥，必須堆焊耐磨合金以提高密封的耐磨性、耐沖蝕、耐劃傷的能力，提高閥的壽命。折疊其他因素對含顆粒的沖蝕介質(zhì)，要考慮閥芯避開高速介質(zhì)的直接沖蝕。對于硬密封，必須有足夠的硬度差，同一硬度材料"互不相讓"，很容易劃傷而引起泄漏。溫度因素影響如下:對高溫介質(zhì)的切斷調(diào)節(jié)閥在室溫下組裝的，在高溫下工作，溫度變化幾百度。熱膨脹會改變裝配時建立的密封比壓。過緊，密封面會卡信，運動時會嚴重檫傷，拉傷;過松，密封壓不夠，兩種情況泄漏都會急劇增加。解決的**好辦法是用彈性閥座來吸收這一變化造成的差異。通常有三種彈性方案:1)彈簧式;2)薄片式柔性金屬環(huán);3)剛?cè)嵯酀膹椥蚤y座。后者**好，既有柔性克服熱膨脹，又有剛度并堆焊耐磨合金來提高耐磨面的可靠性。折疊推薦順序按上所述，切斷閥的主要閥型如下，選擇切斷閥應(yīng)綜合考慮泄漏率、介質(zhì)種類、介質(zhì)溫度、流量系數(shù)等各種參數(shù)和性價比。在如下推薦順序中，先考慮硬密封，再考慮軟密封。1)三偏心金屬硬密封蝶閥;2)雙偏心球面密封蝶閥;3)球閥;4)偏心旋轉(zhuǎn)閥;5)單座閥。適配連接橡膠管管徑：76mm-154mm。北京MTU2000柴油機進氣切斷閥</p><p
