详细信息

一、产品概述Brief introduction of product

    水电站型液控缓闭球阀是对液控缓闭蝶阀应用范围的有力补充，特别适用于高水头的水电站工况。工作时，阀门与水轮机配合，按照水力
过渡过程原理，通过预设的启闭程序，有效消除管路水锤，实现管路可靠截止，起到保护管路系统安全的作用。
    本系列液控缓闭球阀，智能化程度高、功能齐全、性能稳定可靠，且流阻系数极小，全开时的流阻系数与管道相等。我公司并可根据用户
的特殊要求单独进行设计，多方位满足用户对该类产品的需要。
    1、流体阻力小，球阀是所有阀类中流体阻力最小的一种，即使是缩径球阀，其流体阻力也相当小。
    2、开关迅速、方便，只要阀杆转动900，球阀就完成了全开或全关动作，很容易实现快速启闭。
    3、密封性能好。球阀阀座密封圈一般采用聚四氟乙烯等弹性材料制造，易于保证密封，而且球阀的密封力随着介质压力的增加而增大。
    4、阀杆密封可靠。球阀启闭时阀杆只做旋转运动，因此阀杆的填料密封不易被破坏。
    5、球阀的启闭只做90。转动，故易实现自动化控制和远距离控制，球阀可配置气动装置、电动装置、液动装置、气液联动装置或电液联动
装置。
      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.
