在计算过程中，比较完整地考虑了各种阻力矩对起动过程的影响，同时重点考察了平直管出水流道，具有快速闸门带小拍门断流装置形式的起动效果。 - In order to ensure that each valve flap valve seat surface can reach the appropriate location , in valve design hinge agencies , in order to have enough plug valve kai xuan space , and the valve genuine and comprehensive engagement with the valve seat
为了确保阀瓣每次都能到达阀座面的合适位置，阀瓣设计在铰链机构，以便阀瓣具有足够有旋启空间，并使阀瓣真正的、全面的与阀座接触。 - One side , groovy cast steel flap valves increase the head loss , waste electricity , the other side , when flap valves close , it always delay time because of it ' s low proportion . the bump load seriously threaten the safety of pumping station . through the research and development of flap valve used in the renovation practices in the design of air - filled floating flap valve in no . 1 chuhe pumping station of anhui province , the working characteristics and design methods of air - filled floating flap valve are studied in this paper
但在拍门运行使用的同时，又时常暴露出一些缺陷，主要有：一是常规的铸铁或铸钢拍门加大了流道的水头损失，特别是对于装机容量较大的排涝泵站，其电能损耗相当可观；二是拍门在自重下下落关闭时，往往由于过多考虑水头损失导致浮重过小而延误闭门时间，致使水体倒灌，再因缓冲装置失灵导致闭门时门体对门框撞击力很大，严重危及站身安全。 - Based on the research and model test , the head loss of flap valves is analyzed by both mathematical physics method and the equation of criterion , and the impulsive force and open angle of flap valve are researched . the flap valve approximate - calculation method is the emphases in this paper . the design methods and using effect of air - filled floating flap valve are studied in the paper by combining with engineering example
在总结前人研究的基础上，对照试验结果，通过数理解析和准则方程分析了拍门水头损失，研究了拍门水流冲力的求解和拍门开启角度的求解，着重研究分析了拍门近似计算方法，分析拍门在水中的运动规律，并结合工程实例，研究探讨充气浮箱式拍门的配重方法及其使用效果，为今后开拓充气浮箱式拍门的运用领域作些探讨研究。
