液控球閥系列

詳細信息

一、產品概述Brief introduction of product

    水電站型液控緩閉球閥是對液控緩閉蝶閥應用范圍的有力補充，特別適用于高水頭的水電站工況。工作時，閥門與水輪機配合，按照水力
過渡過程原理，通過預設的啟閉程序，有效消除管路水錘，實現管路可靠截止，起到保護管路系統安全的作用。
    本系列液控緩閉球閥，智能化程度高、功能齊全、性能穩定可靠，且流阻系數極小，全開時的流阻系數與管道相等。我公司并可根據用戶
的特殊要求單獨進行設計，多方位滿足用戶對該類產品的需要。
    1、流體阻力小，球閥是所有閥類中流體阻力最小的一種，即使是縮徑球閥，其流體阻力也相當小。
    2、開關迅速、方便，只要閥桿轉動900，球閥就完成了全開或全關動作，很容易實現快速啟閉。
    3、密封性能好。球閥閥座密封圈一般采用聚四氟乙烯等彈性材料制造，易于保證密封，而且球閥的密封力隨著介質壓力的增加而增大。
    4、閥桿密封可靠。球閥啟閉時閥桿只做旋轉運動，因此閥桿的填料密封不易被破壞。
    5、球閥的啟閉只做90。轉動，故易實現自動化控制和遠距離控制，球閥可配置氣動裝置、電動裝置、液動裝置、氣液聯動裝置或電液聯動
裝置。
      Power plant hydraulic control slow closing ball valve is a valuable complementarity for the hydraulic control slow closing butterfly valve. It specially fits for high head
water power plant. It coordinates with hydroturbine, working as per the hydraulic transition principle, effectively eliminates the water hammer effect and ensures reliable shut-
off of pipeline by preset program, therefore, protects the safety of pipelines. This series of hydraulic control slow closing ball valve is with high degree of intelligence, complete
functions, reliable performance and low flow resistance coefficient, the flow resistance coefficient at full opening is similar with the pipeline.We also provide tailor-made
solutions according to user’s unique requirement and meet the users needs in every aspects.
     1 . Low flow resistance. ball valve is with the lowest flow resistance among the valves, even if the reduced port ball valve, the flow resistance is still very low.
     2. Swift and convenient opening and closing. By turning 900 , the ball valve completes full opening or full closing action, which makes it ideal for fast opening and closing.
     3. Excellent sealing. The seat ring of ball valve is mainly resilient material like PTFE, which ensures perfect sealing, furhtermore, the sealing strength of ball valve increases simultaneously with the medium pressure.
     5. The ball valve achieves opening and closing by rotating 900 , which makes it easy to realize automatic control and remote control. Ball valve can be equipped with pneumatic actuator, electric actuator, hydraulic actuator, gas over oil actuator or electric hydraulic actuator.
