</p><p> 本實用新型涉柴油發(fā)動機技術(shù)領域，特別涉及一種柴油發(fā)動機進氣關(guān)斷閥。背景技術(shù)：柴油發(fā)動機的進氣關(guān)斷閥是柴油發(fā)動機進氣系統(tǒng)的關(guān)鍵設備，柴油發(fā)動機在工作過程中，為保證其工作狀態(tài)的平穩(wěn)切換，往往需要在柴油發(fā)動機的進氣關(guān)斷閥關(guān)閉后還能有少量的氣體通過?，F(xiàn)有的柴油機進氣關(guān)斷閥在關(guān)閉時會完全切斷氣流通路，導致柴油機工作狀態(tài)的切換過程不太平穩(wěn)，目前還沒有一種柴油發(fā)動機進氣關(guān)斷閥能夠解決這一技術(shù)問題。技術(shù)實現(xiàn)要素：本實用新型針對現(xiàn)有技術(shù)中存在的柴油發(fā)動機進氣關(guān)斷閥關(guān)閉后會完全切斷氣流通路的技術(shù)問題。本實用新型解決上述技術(shù)問題的技術(shù)方案如下：一種柴油發(fā)動機進氣關(guān)斷閥，包括：執(zhí)行機構(gòu)、閥桿、閥體、接觸部及隔離部；所述執(zhí)行機構(gòu)與所述閥體固定連接；所述閥體內(nèi)設置有進氣腔及出氣腔；所述隔離部固定在所述閥體內(nèi)側(cè)，用于分隔所述進氣腔及出氣腔；所述執(zhí)行機構(gòu)的輸出端與所述閥桿的一端固定連接，所述閥桿的另一端延伸至所述閥體的內(nèi)側(cè)與所述接觸部固定連接；所述隔離部上開設有水平設置的圓形通孔，所述接觸部設置為橢圓形狀，所述接觸部與所述圓形通孔相配合，且所述接觸部所在橢圓的長徑長度小于所述圓形通孔的直徑。進一步的。中國防爆標準GB4556-2001

在現(xiàn)有技術(shù)中，發(fā)動機排氣管用火花熄滅器主要有如下幾種類型：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)復雜，排氣阻力較大，需使用耐腐蝕材料，造價較高；柵片型和疊片型火花熄滅器對于阻止氣體火焰較為有效，但對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，效果當然好，但結(jié)構(gòu)復雜，造價高?？傊?，目前國內(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)比較復雜，而且需使用當前短缺的不銹鋼板材制造，造價貴，推廣應用受到限制。山西卡特皮勒CAT柴油機進氣切斷閥</p><p
