style="text-indent:25px">常用的蝶閥有對夾式蝶閥和法蘭式蝶閥兩種。對夾式蝶閥是用雙頭螺栓將閥門銜接在兩管道法蘭之間，法蘭式蝶閥是閥門上帶有法蘭，用螺栓將閥門上兩頭法蘭銜接在管道法蘭上。蝶閥的結(jié)構(gòu)和在使用過程存在的問題：目前，蝶閥作為一種用來實現(xiàn)管路系統(tǒng)通斷及流量控制的部件，已在石油、化工、冶金、水電等許多領(lǐng)域中得到極為普遍地使用。在已公知的蝶閥技術(shù)中，其密封形式多采用密封結(jié)構(gòu)，密封材料為橡膠、聚四氟乙烯等。因為結(jié)構(gòu)特征的限制，不適應(yīng)耐高溫、高壓及耐腐蝕、抗磨損等職業(yè)。絲扣式自動風(fēng)閥都有哪些減壓閥應(yīng)及時排除管道中的積氣。</p><div

style="text-indent:25px">減壓閥注意事項：1.為了操作和維護(hù)方便，該閥一般直立安裝在水平管道上。2.減壓閥安裝必須嚴(yán)格按照閥體上的箭頭方向保持與流體流動方向一致。如果水質(zhì)不清潔，含有一些雜質(zhì)，必須在減壓閥的上游進(jìn)水口安裝過濾器。3.為了防止閥后壓力超壓，應(yīng)在離閥出口不少于4M處安裝一個減壓閥。4.減壓閥在管道中起到一定的止回作用，為了防止水錘的危害，也可安裝小的膨脹水箱，防止損壞管道和閥門，過濾器必須安裝在減壓閥的進(jìn)水管前，而膨脹水箱必須安裝在減壓閥出水管后！</p><p style="text-indent:25px">軟密封偏心蝶閥適用于通風(fēng)除塵管路的雙向啟閉及調(diào)節(jié)，普遍用于冶金、輕工、電力、石油化工系統(tǒng)的煤氣管道及水道等。金屬對金屬線密封雙偏心蝶閥適用于城市供熱、供氣、供水等煤氣、油品、酸堿等管路，作為調(diào)節(jié)和節(jié)流裝置。金屬對金屬面密封三偏心蝶閥除作為大型變壓吸附（PSA）氣體分離裝置程序控制閥使用外，還可普遍用于石油、石化、化工、冶金、電力等領(lǐng)域，時閘閥、截止閥的良好替代產(chǎn)品。這種蝶閥的應(yīng)用也是很普遍的，并且在多個行業(yè)都可以看到它的身影。減壓閥運行時要避免存留臟物、雜物進(jìn)入減壓閥減壓保障系統(tǒng)。</p><div
