在現(xiàn)有技術(shù)中，發(fā)動(dòng)機(jī)排氣管用火花熄滅器主要有如下幾種類(lèi)型：1）迷宮型火花熄滅器；2）水浴型火花熄滅器；3）柵片型火花熄滅器；4）疊片型火花熄滅器；5）組合型火花熄滅器。迷宮型火花熄滅器只能阻止熾熱的粒子，而不能有效地阻止火焰的傳播，而且由于氣流多次轉(zhuǎn)彎或碰撞，阻力損失大，油耗率高；水浴型火花熄滅器熄火效果較好，但結(jié)構(gòu)復(fù)雜，排氣阻力較大，需使用耐腐蝕材料，造價(jià)較高；柵片型和疊片型火花熄滅器對(duì)于阻止氣體火焰較為有效，但對(duì)于熾熱的固體顆粒阻止效果較差，而且需用耐熱的不銹鋼板制造，加工精度高，造價(jià)貴，組合型火花熄滅器是由上述的二種火花熄滅器聯(lián)合使用，效果當(dāng)然好，但結(jié)構(gòu)復(fù)雜，造價(jià)高?？傊?，目前國(guó)內(nèi)使用的各種火花熄滅器，雖然有一定的熄火能力，但阻力損失大，油耗率高，結(jié)構(gòu)比較復(fù)雜，而且需使用當(dāng)前短缺的不銹鋼板材制造，造價(jià)貴，推廣應(yīng)用受到限制。內(nèi)蒙古進(jìn)氣切斷閥符合防爆規(guī)范E系列切斷閥結(jié)構(gòu)緊湊輕便，堅(jiān)固耐用。</p><div

其密封效果不很理想。這類(lèi)閥的泄漏率通常為10-4，經(jīng)精密研磨后可達(dá)到10-6，可達(dá)較高的密封等級(jí)。球面密封利用球面的球面轉(zhuǎn)動(dòng)與固定的閥定小錐面相切，它們之間為線(xiàn)接觸，這就比上述面對(duì)面密封效果好。球閥、球面密封蝶閥等就是采用這一思路來(lái)制作的，其泄漏率可達(dá)10-6~10-8，高性能的三偏心蝶閥可達(dá)10-8，甚至為零泄漏。折疊密封類(lèi)型軟密封除耐腐蝕的襯里閥門(mén)外，一般的軟密封閥指閥芯或閥座兩者之一采用非金屬材料(主要為聚四氟乙烯和橡膠等)的密封形式的閥。軟密封閥密封效果**佳，但在管道安裝、系統(tǒng)的清洗中都有可能留下或多或少不干凈的雜物(如焊渣、鐵屑等)，它們流經(jīng)調(diào)節(jié)閥時(shí)，容易把軟密封閥座或閥芯劃傷，使泄漏量增加，密封可靠性差。所以，選擇軟密封結(jié)構(gòu)必須考慮介質(zhì)的清潔和投運(yùn)前嚴(yán)格沖洗管道。硬密封硬密封再堆焊耐磨合金是切斷閥的**佳選擇。這種方式在考慮密封性的同時(shí)也考慮了使用壽命和可靠性，雖然出廠(chǎng)指標(biāo)只有10-4~10-5，達(dá)不到軟密封零泄漏的效果，但足以滿(mǎn)足嚴(yán)密切斷的要求，而且它經(jīng)久耐用，從經(jīng)濟(jì)的角度考慮更合算。此外還需要注意以下兩點(diǎn):1)對(duì)密封可靠性的考慮:軟密封，切斷效果好，但不適宜用于顆粒介質(zhì)，一旦劃傷，泄漏會(huì)急劇增加。因此。</p><p>
