优 点 Optimal point 1体阻力小，全通径的基本没有流阻 2结构简单，经济实用，安装方便快捷 3紧密可靠，密封性能好，球体能很好的跟阀体实行密封，在管道工程中达到良好的密封性能 4操作方便，开闭迅速，从全开到全关只要旋转90°，便于远距离的控制 5维修方便，球阀结构简单，密封圈一般都是活动的，拆卸更换都比较方便。 6耐腐蚀性能好，在全开或全闭时，球体和阀座的密封面与介质隔离，介质通过时， 不会引起阀门密封面的侵蚀。 7由于球阀在启闭过程中有擦拭性，所以可用于带悬浮固体颗粒的介质中 8 Q81F球阀可以带锁，防止误操作带来的危险，安全可靠 Body resistance is small, the whole diameter of the basic no flow resistance Simple structure, economical and practical, convenient and quick installation 3 tight and reliable, good sealing performance, the ball can be well sealed with the valve body, achieving good sealing performance in pipeline engineering 4. Easy operation, quick opening and closing, from full opening to full closing, only 90° rotation is required, which is convenient for remote control 5 convenient maintenance, simple structure of the ball valve, sealing ring is generally mobile, disassembly and replacement are more convenient. 6 good corrosion resist ance, in full open or full closed , ball and seat sealing sur fac e and me dia isolation, the me dia through, will not c ause the e rosion of valve se aling sur fac e. Due to the ball valve in the opening and closing process of wiping, so can be used with suspended solid par ticles in the medium 8 Q81F ball valve can be locked to prevent the risk of misoperation, safe and reliable 适用场合 Applicable occasions 在各种化工，机电工程，机械制造，船舶，电力，石化，治金，水暖，水处理，机械设备制造，气动管路，液压管路，等诸多行业大量应用 In a variety of chemical, mechanical and electrical engineering, machinery manufacturing, shipbuilding, power, petrochemical, gold, plumbing, water treatment, mechanical equipment manufacturing, pneumatic piping, hydraulic piping, and many other industries a large number of applications
