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。對于易燃易爆、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(jī)溶劑浸泡，擦拭干凈。4、然后用真空袋進(jìn)行密封。5、后裝箱。6、運輸過程中要采取措施保證包封不破損。閥門清洗步驟編輯閥門的零部件在組裝前必須經(jīng)過以下過程處理：1、根據(jù)加工要求，部分零部件需要做拋光處理，表面不能有加工毛刺等；2、所有零部件進(jìn)行脫脂處理；3、脫脂完成后進(jìn)行酸洗鈍化，清洗劑不含磷；4、酸洗純化后用純凈水沖洗干凈，不能有藥劑殘留，碳鋼部件省去此步驟。新疆鑄鋼球閥生產(chǎn)廠家</p><p
