流阻小的閥門，能源消耗少。對(duì)低壓力、大流量的水、空氣等介質(zhì)，選用大口徑閘閥和蝶閥比較合理。蝶閥可作截?cái)嘤?，又能作?jié)流用。3.安全可靠性一般水蒸氣管道上可采用+球墨鑄鐵閥門和鑄鋼閥門。但在室外蒸汽管道上，若停止供氣，水易結(jié)冰而使閥門破裂，特別是在我國(guó)北方。因此，宜采用鑄鋼或鍛鋼閥門，同時(shí)要做好閥門的防凍保溫工作。乙炔類易燃易爆的介質(zhì)，對(duì)密封性要求高。壓力在，應(yīng)采用隔膜閥，但不宜用在真空設(shè)備的管道上。對(duì)危害性很大的放射性介質(zhì)和劇毒介質(zhì)，應(yīng)采用波紋管結(jié)構(gòu)的閥門，以防介質(zhì)從填料函中泄漏。對(duì)于帶有驅(qū)動(dòng)裝置（電動(dòng)、液動(dòng)、氣動(dòng)）的閥門，除要求驅(qū)動(dòng)裝置安全可靠外，還要根據(jù)工況條件的不同，選用相應(yīng)的驅(qū)動(dòng)裝置。例如，在需要防火的工況下，應(yīng)選用液動(dòng)、氣動(dòng)裝置的閥門；必須選用電動(dòng)裝置的閥門時(shí)，其電動(dòng)裝置應(yīng)為防爆型，以避免電弧引起火災(zāi)。4.操作和維修方便對(duì)于大型閥門和處于高空、高溫、高壓、危險(xiǎn)、遠(yuǎn)距離的閥門，應(yīng)選用齒輪傳動(dòng)、鏈條傳動(dòng)或帶有電動(dòng)裝置、氣動(dòng)裝置、液動(dòng)裝置的閥門。在操作空間受到限制的場(chǎng)合，不宜處于明桿閘閥，以選用暗桿閘閥為好。**好是用蝶閥。對(duì)需要快關(guān)、快開的閥門，不宜處于一般的閘閥、截止閥。阿克蘇閘閥廠家。。。</p><div

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：?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(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、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?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、后裝箱。6、運(yùn)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。烏魯木齊黃銅絲扣截止閥廠家</p><p
