D671X氣動(dòng)對(duì)夾蝶閥的概述
氣動(dòng)蝶閥是管線(xiàn)優(yōu)先選用的常規(guī)蝶閥,具有結(jié)構(gòu)簡(jiǎn)潔,流阻系數(shù)小,流量特性趨于直線(xiàn),不會(huì)滯留雜物。且重量輕,安裝方便,驅(qū)動(dòng)扭矩較小的優(yōu)點(diǎn)。氣動(dòng)蝶閥既可作切斷介質(zhì)用,又可作調(diào)節(jié)介質(zhì)的流量用。驅(qū)動(dòng)裝置根據(jù)用戶(hù)要求,分別可采用手動(dòng)、電動(dòng)、氣動(dòng)等方式。選用不同材料的零件,配用不同材料的密封圈,可適應(yīng)不同的介質(zhì)、工況,使成本與性能達(dá)到效果。 氣動(dòng)蝶閥適用于溫度≤120℃或≤150℃,公稱(chēng)壓力≤1.6MPa給排水、污水、食品、供暖、燃?xì)?、船舶、水電、冶金、能源系統(tǒng)以及輕紡等行業(yè),特別適用于雙向密封和閥體易銹蝕場(chǎng)合,作調(diào)節(jié)流量和截流介質(zhì)。
