防結(jié)露蝶閥：結(jié)露是潮濕環(huán)境、管道介質(zhì)和環(huán)境溫度溫差較大時必然出現(xiàn)的現(xiàn)，結(jié)露不僅容易使閥門生銹，使電動、手動執(zhí)行器出現(xiàn)故障，還會因為滴水而影響現(xiàn)場工作、生活條件。目前市場一些所謂“防結(jié)露涂料”和“壓鑄鋁合金閥體”防結(jié)露效果均不理想。解決結(jié)露問題**好的辦法是用非金屬材料將閥體和執(zhí)行隔開，甚至適用非金屬的執(zhí)行器。防結(jié)露蝶閥的價格必普通蝶閥稍貴一點，大概只高15％左右，因此很有推廣價值，尤其是用于電動閥門上。電動蝶閥：采用對加蝶閥或法蘭蝶閥作為工作部件，以電動執(zhí)行器作為驅(qū)動部件，接受并反饋遠(yuǎn)程或現(xiàn)場開關(guān)信號，實現(xiàn)關(guān)斷或開啟管道的作用。適合用于需要遠(yuǎn)程控制或者不便手動操作的地方；閥體和普通中線軟密封蝶閥相同；電動執(zhí)行器采用角回轉(zhuǎn)式，可以接受遠(yuǎn)程開關(guān)、調(diào)節(jié)控制，并反饋開關(guān)、調(diào)節(jié)信號；驅(qū)動電源一般為AC220V，也可以根據(jù)現(xiàn)場條件要求廠家定做；適合開關(guān)或調(diào)節(jié)的用途。截止閥阻力較大，關(guān)斷可靠，體積較大；有金屬密封，有橡膠密封，生產(chǎn)工藝較簡單；在關(guān)斷閥門中，阻力較大，但是可以手動調(diào)流，必要時可以起到手動平衡的作用，且抗汽蝕能力較強；DN50及以下多為螺紋連接，多采用全銅結(jié)構(gòu)，但是一般由銅閥專業(yè)廠家生產(chǎn)。烏魯木齊自動閥門價格</p><p
