結(jié)構(gòu)型式在切斷效果方面，角行程閥比直行程閥（如單座閥、套筒閥、閘閥等）結(jié)構(gòu)更簡單、密封效果更可靠、更具有優(yōu)越性。比較有**性的有三偏心硬密封蝶閥、球閥等。密封面面對面密封常見的柱塞閥芯，其密封面為60°的小錐面，此小錐面的寬度通常在～2mm之間，要密封好就必須保證兩個錐面良好接觸。但事實上，它始終受到加工誤差的影響（如同心度、不圓度、傾斜度等），其密封效果不很理想。這類閥的泄漏率通常為10-4，經(jīng)精密研磨后可達到10-6，可達較高的密封等級。球面密封利用球面的球面轉(zhuǎn)動與固定的閥定小錐面相切，它們之間為線接觸，這就比上述面對面密封效果好。球閥、球面密封蝶閥等就是采用這一思路來制作的，其泄漏率可達10-6～10-8，高性能的三偏心蝶閥可達10-8，甚至為零泄漏。

其密封效果不很理想。這類閥的泄漏率通常為10-4，經(jīng)精密研磨后可達到10-6，可達較高的密封等級。球面密封利用球面的球面轉(zhuǎn)動與固定的閥定小錐面相切，它們之間為線接觸，這就比上述面對面密封效果好。球閥、球面密封蝶閥等就是采用這一思路來制作的，其泄漏率可達10-6~10-8，高性能的三偏心蝶閥可達10-8，甚至為零泄漏。折疊密封類型軟密封除耐腐蝕的襯里閥門外，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，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)的清潔和投運前嚴格沖洗管道。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也考慮了使用壽命和可靠性，雖然出廠指標只有10-4~10-5，達不到軟密封零泄漏的效果，但足以滿足嚴密切斷的要求，而且它經(jīng)久耐用，從經(jīng)濟的角度考慮更合算。此外還需要注意以下兩點:1)對密封可靠性的考慮:軟密封，切斷效果好，但不適宜用于顆粒介質(zhì)，一旦劃傷，泄漏會急劇增加。因此。吉林洋馬YANMAR柴油機進氣切斷閥</p><p
