切斷閥的可靠性1、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，條件允許時(shí)盡量選用硬密封。"O"型球閥硬密封可達(dá)10-5，三偏心蝶閥可達(dá)零泄漏。2、對(duì)密封耐磨性的考慮：除選硬密封外，對(duì)泄漏要求10-4以上的切斷型調(diào)節(jié)閥，必須堆焊耐磨合金以提高密封的耐磨性、耐沖蝕、耐劃傷的能力，提高閥的壽命。3、對(duì)高溫介質(zhì)的切斷調(diào)節(jié)閥在室溫下組裝的，在高溫下工作，溫度變化幾百度。熱膨脹會(huì)改變裝配時(shí)建立的密封比壓。過(guò)緊，密封面會(huì)卡信，運(yùn)動(dòng)時(shí)會(huì)嚴(yán)重檫傷，拉傷；過(guò)松，密封壓不夠，兩種情況泄漏都會(huì)急劇增加。解決的比較好辦法是用彈性閥座來(lái)吸收這一變化造成的差異。通常情況下有三種彈性方案：①?gòu)椈墒?；②薄片式柔性金屬環(huán)；③剛?cè)嵯酀?jì)的彈性閥座。后者比較好，既有柔性克服熱膨脹，又有剛度并堆焊耐磨合金來(lái)提高耐磨面的可靠性。4、對(duì)含顆粒的沖蝕介質(zhì)，要考慮閥芯避開高速介質(zhì)的直接沖蝕。5、對(duì)于硬密封，必須有足夠的硬度差，同一硬度材料"互不相讓"，很容易劃傷而引起泄漏。內(nèi)蒙古杰瑞JEREH壓裂車進(jìn)氣切斷閥</p><p
