襯氟對夾蝶閥D371F采用帶有球形密封表面的襯聚四氟乙烯包襯蝶板，配以閥座基部的 硅橡膠襯墊調(diào)節(jié)閥門的密封性能；該閥門操作輕便，嚴(yán)密的密封性能，超 長的使用壽命；可作快速切斷或調(diào)節(jié)流量之用。適用于要求可靠密封和 良好調(diào)節(jié)特性的場合。閥體采用分體式，閥軸兩端的密封由蝶板與閥座 之間的旋轉(zhuǎn)基面加氟橡膠來控制；從而達(dá)到產(chǎn)品結(jié)構(gòu)緊湊、外形美觀，工藝合理、性能可靠。保證閥軸不與腔內(nèi)流體介質(zhì)接觸，更換閥軸時非常方便，閥門不需要拆離管道即可完成。雙德D371F型襯氟蝶閥廣泛適用于各種不同類型工業(yè)管道中液體和氣體（包括蒸 氣）的輸送，特別是具有嚴(yán)重腐蝕性介質(zhì)的使用場合，如：硫酸、氫氟酸、磷酸、氯氣、強(qiáng)等具有強(qiáng)腐蝕性的介質(zhì)。雙德襯氟蝶閥特點(diǎn)及用途 Features and usage：雙德軟密封蝶閥通常用于溫度≤120℃，公稱直徑≤1.6Mpa的食品、醫(yī)藥、化工、石油、輕紡、造紙等給排水、氣體管道上作調(diào)節(jié)流量和截斷流體的作用。
襯氟對夾蝶閥主要特點(diǎn)
1、設(shè)計新穎、合理、結(jié)構(gòu)*，重量輕，啟閉迅速。2、操作力矩小，操作方便，省力靈巧。
2、可任意位置安裝，維修方便。4、密封件可更換，密封性能可靠達(dá)到雙向密封零泄漏、
3、密封材料耐老化、耐腐蝕，使用壽命長等特點(diǎn)。
Softly seals the butterfly valve usually to use in the temperature<=120℃,nominal pressure<=1.6Mpafood,the medicine,the chemical industry,The petroleum,the electric power,lightly spin,the papermaking and so on for draining water,on the gas pipiline makes the adjustment currentCapacity and the interruption fluid function,its main charactristic is:
1,Design novel,reasonable,structure unique,the weight is light,opens shuts the news fast.
2,Operation moment of force is small,the ease of operation,reduces effort cleverly.
3,Mau any position installment,the service be convenient.
4,Seal may replace,the sealing property reliably achieved bidirectional seal zero divulges.
5,Packing material must get older,anti-corrosive,the service life is longer and so on the characteristic.
