電動(dòng)硬密封球閥Q947H用途：
　　電動(dòng)球閥是一種轉(zhuǎn)角為90°的旋轉(zhuǎn)類球閥，密封性能優(yōu)良，流通能力大，流阻系數(shù)小，結(jié)構(gòu)簡(jiǎn)單、維修方便、使用壽命長(zhǎng)，閥體通道和連接管徑相等并成一直徑，介質(zhì)幾乎可以毫無(wú)損失的流過(guò)。配用DKJ-Ⅱ、Ⅲ執(zhí)行器引配日本工裝、西德歐姆龍等高性能執(zhí)行機(jī)構(gòu)。產(chǎn)品通常用于密封要求嚴(yán)格的場(chǎng)合，除控制氣體、液體、蒸汽介質(zhì)外，還適宜控制污水和含有纖維性雜質(zhì)的介質(zhì)，廣泛用于石油、化工、冶金、輕工、造紙、電站、制冷等工作領(lǐng)域。

電動(dòng)硬密封球閥Q947H是一種重要的閥類，在石油化工、長(zhǎng)輸管線等領(lǐng)域有廣泛應(yīng)用。球閥的關(guān)閉件是一個(gè)帶孔的球體（或部分球），球體隨閥桿轉(zhuǎn)動(dòng)，實(shí)現(xiàn)閥門的開(kāi)啟或關(guān)閉。

電動(dòng)硬密封球閥Q947H旋轉(zhuǎn)90°即可全關(guān)全開(kāi)，與相同規(guī)格的閘閥、截止閥比較、球閥體積小、重量輕，便于管道安裝。
