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。折疊編輯本段例外情況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。這種方法可以節(jié)省空間并在很多情況下比較經(jīng)濟。3.法蘭式安裝的薄膜液位變送器這種型式的儀表安裝可設(shè)計成與容器壁齊平，變送器可用與法蘭同樣大小的切斷閥安裝在容器管嘴和變送器之間。折疊編輯本段用途切斷閥的用途很廣，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。F系列切斷閥

進口氣動切斷閥工作原理圖及結(jié)構(gòu)特點進口氣動切斷閥是用于工藝管道中突發(fā)故障或事故時，將管路介質(zhì)（液體、氣體）流體緊急快速截斷的高性能切斷閥，具有動作迅速、嚴密切斷、安全可靠等特點，在其高危險物料的加工處理，貯存運輸過程中被得到普遍應(yīng)用，在氣體泄漏、意外事故、操作不當、人員沒辦法靠近時，能夠遠距離快速關(guān)閉閥門，起安全保護作用。進口氣動切斷閥結(jié)構(gòu)特點：1、切斷閥采用薄膜式多彈簧執(zhí)行機構(gòu)與調(diào)節(jié)機構(gòu)用三根立柱相連，整個高度可減小約30％，重量可減輕約30％。2、閥體按流體力學原理設(shè)計成等截面低流阻流道，額定流量系數(shù)增大30％。3、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(zhì)合金，軟密封型為軟質(zhì)材料制作，關(guān)閉時密封性能優(yōu)良。4、平衡型閥內(nèi)件，提高了切斷閥的許用壓差。進口氣動切斷閥工作原***動切斷閥主要由執(zhí)行機構(gòu)與閥體兩部分組成，通常由控制室/控制中心操作，也可以在現(xiàn)場安全地操作。氣動切斷閥對閥的基本要求是：關(guān)閉嚴密快速，并具火災(zāi)安全結(jié)構(gòu)。雖然，常規(guī)閥門中，高密封性能的金屬密封是較佳選擇，當采用軟密封結(jié)構(gòu)時，必須是火災(zāi)安全型結(jié)構(gòu)，以保證軟密封結(jié)構(gòu)失效后，仍能截斷危險物料而不流入事故場所！E系列切斷閥E-M系列。陜西長沙湘普進氣切斷閥</p><p
