特點(diǎn)The characteristics of
球閥的主要特點(diǎn)是本身結(jié)構(gòu)緊湊，密封可靠，結(jié)構(gòu)簡單，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、過氧化.氫、甲烷和乙烯等，在各行業(yè)得到廣泛的應(yīng)用。球閥閥體可以是整體的，也可以是組合式的。Ball valve itself is the main characteristics of compact structure, reliable sealing, simple structure, convenient maintenance, sealing surface and the spherical often in the closed state, not easily be medium erosion, easy operation and maintenance, applicable to water, solvent, acid and gas, such as general work medium, but also is suitable for the working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene, widely used in various fields. Ball valve body can be a whole, also can be combined.
