調(diào)節(jié)閥管線由于組合或安裝不當會產(chǎn)生各種應(yīng)力，例如高溫介質(zhì)產(chǎn)生的熱應(yīng)力，安裝時緊固力不均衡造成的切斷閥應(yīng)力，人為的某些碰撞給調(diào)節(jié)閥及其管道造成的應(yīng)力等。這些應(yīng)力作用在調(diào)節(jié)閥及其管線上，很容易對調(diào)節(jié)閥的性能產(chǎn)生影響，嚴重時會影響到調(diào)節(jié)系統(tǒng)本身，導(dǎo)致閥桿和導(dǎo)向件變形而不能和閥座對準中心;對于分體式閥體的調(diào)節(jié)閥，可能引起閥體法蘭的脫開;應(yīng)力還可能引起閥座泄漏等。因此，任何時刻都要保證避免或消除應(yīng)力，把應(yīng)力導(dǎo)向遠離調(diào)節(jié)閥的地方。對在性危險場所使用的調(diào)節(jié)閥和有關(guān)附件應(yīng)檢查其安全運行情況，例如，密封蓋是否擰緊，安全柵的運行情況，電源供應(yīng)情況等，保證調(diào)節(jié)閥及有關(guān)附件能夠安全運行。安裝調(diào)節(jié)閥的比較好位置是使閥桿的行程方向與閥體上方的執(zhí)行機構(gòu)在一個垂直平面上。如果調(diào)節(jié)閥必須安裝在使閥桿水平移動的位置，或者閥桿的移動方向與水平面有一定的傾角時，就應(yīng)該把執(zhí)行機構(gòu)支撐起來，使調(diào)節(jié)閥的各個部件都處于自然狀態(tài)。如果不加設(shè)支撐或者支撐加設(shè)不當都可能造成調(diào)節(jié)閥閥桿與閥座的不同心，容易導(dǎo)致差變或使填料泄漏等故障。即使調(diào)節(jié)閥有固定和支撐措施，也必須定期進行檢查，一般2～3個月檢查一次。填料和注油器在短期使用后需要重新調(diào)整。

當柴油機在有可燃氣體，蒸汽及粉塵存在的場所使用時就會變成一個潛在的著火源，由其引起的火災(zāi)對員工、產(chǎn)品及周圍的環(huán)境都會產(chǎn)生災(zāi)難性的破壞。從1972年起，Chalwyn公司便開始提供進氣切斷閥來幫助避免產(chǎn)生此種問題。當發(fā)動機吸入混合可燃氣體而引起超速時，該裝置能夠自動切斷發(fā)動機進氣，從而實現(xiàn)發(fā)動機安全停車。隨著該系列產(chǎn)品的研發(fā)成功，我們又陸續(xù)開發(fā)一系列柴油機安全解決設(shè)備。目前，Chalwyn已成為柴油機安全防護領(lǐng)域的行業(yè)先行者。

如切斷閥只能在兩種狀態(tài)下工作，全開或全關(guān)。當閥瓣在閥座內(nèi)處于中間位置時，由于壓降大而產(chǎn)生大的流速，這就形成汽蝕的條件，引起侵蝕，破壞閥瓣和閥座的密封面，結(jié)果喪失了關(guān)閉件的密封性，在滲漏介質(zhì)對金屬的作用下，初始時的小漏很快會變成大漏。[1]切斷閥材質(zhì)編輯所有切斷閥的材質(zhì)、壓力等級和連接方式，必須同與其相連接的設(shè)備的規(guī)格相符。這一點適用于所有的切斷閥，無論它是直接安裝在設(shè)備上還是裝在一個與設(shè)備相連的立管上。[2]切斷閥位置和尺寸編輯切斷閥可裝在容器接頭或立管上。當閥連接在立管上時，接頭尺寸至少為3/4英寸。當容器接頭是法蘭式管嘴并且切斷閥直接安裝在管嘴上時，接頭**小尺寸為1英寸。當容器接頭是管接頭且切斷閥安裝在一個短節(jié)上時，接頭的**小尺寸為3/4英寸，（除下述提到的例外情況外）。容器和切斷閥之間的配件或管道要減至**低限度。切斷閥例外情況編輯1．特殊應(yīng)用如果容器的管嘴是法蘭式的并且被連接的儀表(如差壓計)是小尺寸的螺紋接頭，這時切斷閥**小可用3/4英寸的口徑并可以用一個縮徑法蘭和短節(jié)連接到容器管嘴上。2．雙切斷閥有些公司允許在并聯(lián)的儀表上采用雙切斷閥，這些儀表用直接裝在管嘴上的三通連接起來。電纜驅(qū)動式停車系統(tǒng)就是用手拉動電纜的T型手柄來關(guān)閉進氣切斷閥，從而實現(xiàn)停車。廣西阿特拉斯ATLAS

結(jié)構(gòu)型式在切斷效果方面，角行程閥比直行程閥（如單座閥、套筒閥、閘閥等）結(jié)構(gòu)更簡單、密封效果更可靠、更具有優(yōu)越性。比較有**性的有三偏心硬密封蝶閥、球閥等。密封面面對面密封常見的柱塞閥芯，其密封面為60°的小錐面，此小錐面的寬度通常在～2mm之間，要密封好就必須保證兩個錐面良好接觸。但事實上，它始終受到加工誤差的影響（如同心度、不圓度、傾斜度等），其密封效果不很理想。這類閥的泄漏率通常為10-4，經(jīng)精密研磨后可達到10-6，可達較高的密封等級。球面密封利用球面的球面轉(zhuǎn)動與固定的閥定小錐面相切，它們之間為線接觸，這就比上述面對面密封效果好。球閥、球面密封蝶閥等就是采用這一思路來制作的，其泄漏率可達10-6～10-8，高性能的三偏心蝶閥可達10-8，甚至為零泄漏。河北進氣切斷閥CE安全認證</p><p
