如切斷閥只能在兩種狀態(tài)下工作，全開或全關。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，結果喪失了關閉件的密封性，在滲漏介質對金屬的作用下，初始時的小漏很快會變成大漏。[1]切斷閥材質編輯所有切斷閥的材質、壓力等級和連接方式，必須同與其相連接的設備的規(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備上還是裝在一個與設備相連的立管上。[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。</p><p> 切斷閥的用途很廣，可用于切斷煤氣、助燃空氣、冷風及煙氣。煤氣切斷閥是把燃燒器與煤氣管道切斷。助燃空氣切斷閥是將燃燒器與助燃空氣管道切斷。熱風爐在送風期用燃燒器切斷閥將熱風爐與燃燒器或煤氣系統(tǒng)及助燃空氣系統(tǒng)隔斷。煙道閥使熱風爐與煙道隔離。冷風閥的用途是在熱風爐燃燒期把冷風管道與熱風爐隔開。當冷風管道內(nèi)壓力下降時，高爐內(nèi)的煤氣可能通過混風管滲入冷風管道，形成性氣體，為避免這種情況發(fā)生，在混風調(diào)節(jié)閥與熱風管道之間的混風管道上設置混風切斷閥。[3]主要應用于以下場合：1、與可燃氣體泄漏監(jiān)測儀器聯(lián)接，當儀器檢測到可燃氣體泄漏時，自動快速關閉主供氣閥門，切斷燃氣的供給，及時制止惡性事故的發(fā)生；2、與熱力設備的極限溫度壓力安全控制器聯(lián)接，當設備內(nèi)檢測點的溫度壓力超過設定的極限數(shù)值時，自動快速關閉供氣閥門，停止燃料的供給；3、與高層建筑的**消防報警系統(tǒng)聯(lián)接，當大廈發(fā)生火警時，自動切斷大廈內(nèi)的燃氣供應，防止煤氣的發(fā)生；4、在城市或工廠的燃氣供應管網(wǎng)內(nèi)設置ZCR燃氣緊急切斷閥，可在**控制室內(nèi)集中控制，遠程遙控緊急關閉事故現(xiàn)場的管線供氣。電纜驅動式停車系統(tǒng)就是用手拉動電纜的T型手柄來關閉進氣切斷閥，從而實現(xiàn)停車。</p><div

1、閥體結構有單座、套筒、雙座（二位三通）三種，密封形式有填料密封和波紋管密封兩種，產(chǎn)品公稱壓力等級有PN10、16、40、64四種，公稱口徑范圍DN20～200mm。適用流體溫度由-60～450℃。泄漏量等級為IV級或Ⅵ級。流量特性為快開；2、采用多彈簧執(zhí)行機構與調(diào)節(jié)機構用三根立柱相連，整個高度可減小約30%，重量可減輕約30%；3、閥體按流體力學原理設計成等截面低流阻流道，額定流量系數(shù)增大30%；4、閥內(nèi)件密封部分有嚴密型和軟密封兩種，嚴密型為堆焊硬質合金，軟密封型為軟質材料制作，關閉時密封性能優(yōu)良；5、平衡型閥內(nèi)件，提高了切斷閥的許用壓差；6、波紋管密封型對移動的閥桿形成完全的密封，堵絕了介質外漏的可能性；7、活塞式執(zhí)行機構，操作力大，使用壓差大。

2、當事故發(fā)生時，閥門線圈瞬時通電，觸發(fā)閥門快速關閉，進入自鎖狀態(tài)。此時即使撤去電源，閥門仍處于自鎖狀態(tài)，不會重新自動打開。3、閥門采用先導式閥瓣，開啟輕松，即使壓力達到6bar開啟也十分輕松，口徑大于DN125，采用杠桿手柄，使閥門達到開關省力、快速。4、當工作人員處理完事故，人工重新開啟閥門，才會恢復供氣。注：根據(jù)客戶要求也可提供斷電關閉的常閉型緊急切斷閥。[1]緊急切斷閥分類編輯緊急切斷閥彈簧緊急切斷閥彈簧緊急切斷閥是在遇到突發(fā)情況斷電后緊急關閉閥門或者打開閥門，它的工作原理是：電動彈簧緊急切斷閥在通電后電機電動執(zhí)行器里面的卷簧，把扭矩力傳導至卷簧上，在斷電時卷簧釋放里面儲存的扭矩力，帶動閥門迅速的關閉或者打開。它的優(yōu)點是關閉迅速，關閉時間只需1-2S。緊急切斷閥蓄電容緊急安全閥蓄電容緊急安全閥是在執(zhí)行器內(nèi)部裝有蓄電容儲能裝置，執(zhí)行器通電正常運轉時，蓄電容充電。斷電時蓄電容釋放電能，帶動電機、齒輪裝置開閉閥門。它的優(yōu)點是：蓄電容充放電時間短，壽命時間長。緊急切斷閥電磁閥電磁閥是新型的燃氣管道工程的安全配套裝置。[2]緊急切斷閥相關資料編輯緊急切斷閥技術參數(shù)1、適用于煤氣、天然氣及液化石油氣。中國香港柴油發(fā)電機組進氣切斷閥</p><p
