style="text-indent:25px">閥門(mén)的密封性能是指閥門(mén)各密封部位阻止介質(zhì)泄漏的能力，它是閥門(mén)比較重要的技術(shù)性能指標(biāo)。閥門(mén)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，也就是一般所說(shuō)的關(guān)不嚴(yán)，它將影響閥門(mén)截?cái)嘟橘|(zhì)的能力。對(duì)于截?cái)嚅y類(lèi)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)造成問(wèn)題。對(duì)于易燃易爆、有害或有放射的介質(zhì)，外漏更是不能允許的，所以閥門(mén)需要具有可靠的密封性能。</p><p

以保證密封面的密封性。另外不銹鋼閘閥只能起到全開(kāi)和全關(guān)的作用, 不能作為調(diào)節(jié)和節(jié)流的功能。閥門(mén)的主要組成構(gòu)造是什么？</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"
