機動車排出的廢氣中的火花由前管進入中管中的小管時，氣體通道驟然減小，增加了火花撞擊管壁而熄滅的機會。接著，廢氣由中管中的小管進入后管中的小管，由于小管和小管之間呈交叉排列，對殘余的火花又進行一次撞擊熄滅。該防火消聲器雖然能在一定程度上對排氣管廢氣中的火花進行熄滅，但是由于廢氣在管道中基本上是直線行走，因此微量的火花還有可能從火花熄滅器中排出，引起火災(zāi)事故。該火花熄滅器功率損失比(損失功率/原發(fā)動機功率）為3%，超過國家標準(審批稿）規(guī)定的功率損失比≤2%的標準。由于結(jié)構(gòu)不合理，小管子容易結(jié)炭，造成氣體通道不暢，當前管大量廢氣不能順利進入小管時，會造成前管壓力增大而炸裂，縮短使用壽命。其它，還存在著自重重，造價高等缺陷。 </p><p> 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廣泛應(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。氣動薄膜切斷閥氣動切斷閥結(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(xué)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。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比較好選擇，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！氣動切斷閥在無氣壓情況下。AMOT

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。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。上海派若搬PYROBAN防爆設(shè)備進氣切斷閥</p><p

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(dǎo)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。上海派若搬PYROBAN防爆設(shè)備進氣切斷閥</p></p><br
