    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

  • A flap vlave used in pumping station is a kind of hydraulic - operated automatic gate , which is similar to a hinged check vaive . because of their simple structure and reliability , being able to shorten the length of outlet passage and facilitate the starting of pumping system in comparison with siphonic vacuum - distroied cutoff scheme . so it is propitious to be used and save investment but at the same time , flap valves always show some disadvantage
    因拍门简单、可靠,与虹吸真空破坏截流闭锁方式相比,可以缩短出水管道(流道)长度,并利于泵系统起动,与快速闸门相比,拍门也有诸多优点,闸门门体易关闭不到位或卡住不能活动,因为门槽和?块较轴孔容易残留异物,闸门门体克服滑动阻力不仅无机械增益,且阻力和动力不在一直线上,门体易倾斜而自锁,而拍门的工作可靠性则远高于快速闸门。
