閥門性能檢測要求1、閥門某一規(guī)格批量制造時，應(yīng)委托官方性機構(gòu)進(jìn)行以下性能的檢測：①閥門在工壓狀況下的啟閉力矩；②閥門在管道輸水狀況下的流阻系數(shù)的檢測。2、閥門在出廠前應(yīng)進(jìn)行以下的檢測：①閥門在開啟狀況下，閥體應(yīng)承受閥門工壓值二倍的內(nèi)壓檢測；②閥門在關(guān)閉狀況下，兩側(cè)分別承受11倍閥門工壓值，無滲漏；但金屬密封的蝶閥，滲漏值亦不大于相關(guān)要求。閥門密封要求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，它是閥門很重要的技術(shù)性能指標(biāo)。閥門的密封部位有三處：啟閉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，也就是通常所說的關(guān)不嚴(yán)，它將影響閥門截斷介質(zhì)的能力。對于截斷閥類來說，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。外漏會造成物料損失，污染環(huán)境，嚴(yán)重時還會造成事件。對于易燃易爆、0或有放射的介質(zhì)，外漏更是不能允許的，因而閥門必須具有可靠的密封性能。閥門其他要求1、裝配完成的閥門用氮氣至少吹掃1分鐘。2、氣密試驗必須是用純凈的氮氣。3、氣密試驗合格后進(jìn)行包封，用干凈聚乙烯帽密封，聚乙烯帽使用前應(yīng)用有機溶劑浸泡，擦拭干凈。烏魯木齊立臥兩用止回閥烏魯木齊減壓穩(wěn)壓閥批發(fā)。</p><div
