?硅溶膠球閥概述:
浮動(dòng)球閥啟閉件(球體)由閥桿帶動(dòng),并繞閥桿的軸線作旋轉(zhuǎn)運(yùn)動(dòng)的閥門。主要用于截?cái)嗷蚪油ü苈分械慕橘|(zhì),亦可用于流體的調(diào)節(jié)與控制,浮動(dòng)球閥本身結(jié)構(gòu)緊湊,密封可靠,結(jié)構(gòu)簡(jiǎn)單,維修方便,密封面與球面常在閉合狀態(tài),不易被介質(zhì)沖蝕,易于操作和維修,適用于水、溶劑、酸和天然氣等一般工作介質(zhì),而且還適用于工作條件惡劣的介質(zhì),如氧氣、過(guò)氧化氫、甲烷和乙烯等,在各行業(yè)得到廣泛的應(yīng)用。
