①閥門(mén)在工壓狀況下的啟閉力矩；②閥門(mén)在管道輸水狀況下的流阻系數(shù)的檢測(cè)。2、閥門(mén)在出廠前應(yīng)進(jìn)行以下的檢測(cè)：①閥門(mén)在開(kāi)啟狀況下。閥體應(yīng)承受閥門(mén)工壓值二倍的內(nèi)壓檢測(cè)；②閥門(mén)在關(guān)閉狀況下，兩側(cè)分別承受11倍閥門(mén)工壓值，無(wú)滲漏；但金屬密封的蝶閥。滲漏值亦不大于相關(guān)要求。閥門(mén)密封要求閥門(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)**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，也就是通常所說(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***。對(duì)于易燃易爆、0或有放射的介質(zhì)。外漏更是不能允許的，因而閥門(mén)必須具有可靠的密封性能。閥門(mén)其他要求1、裝配完成的閥門(mén)用氮?dú)庵辽俅祾?分鐘。2、氣密試驗(yàn)必須是用純凈的氮?dú)狻?、氣密試驗(yàn)合格后進(jìn)行包封，用干凈聚乙烯帽密封，聚乙烯帽使用前應(yīng)用有機(jī)溶劑浸泡，擦拭干凈。4、然后用真空袋進(jìn)行密封。5、***裝箱。
