閥門的密封性能是指閥門各密封部位阻止介質(zhì)泄漏的能力，它是閥門重要的技術(shù)性能指標(biāo)。閥門的密封部位有三處：?jiǎn)㈤]件與閥座兩密封面間的接觸處；填料與閥桿和填料函的配合處；閥體與閥蓋的連接處。其中前一處的泄漏叫做內(nèi)漏，也就是通常所說(shuō)的關(guān)不嚴(yán)，它將影響閥門截?cái)嘟橘|(zhì)的能力。對(duì)于截?cái)嚅y類來(lái)說(shuō)，內(nèi)漏是不允許的。后兩處的泄漏叫做外漏，即介質(zhì)從閥內(nèi)泄漏到閥外。外漏會(huì)造成物料損失，污染環(huán)境，嚴(yán)重時(shí)還會(huì)造成事故。對(duì)于易燃易爆、有毒或有放射的介質(zhì)，外漏更是不能允許的，因而閥門必須具有可靠的密封性能。FINDEVA GT25
