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。 - The main work is done with the help of model experiment . in the flood - relief experiment , the flood carrying capacity of spillway tunnel is checked . in the hydraulic experiment of the diversion power conduit system , the followings are studied : the flow condition and fluctuation in the surge chamber , the distribution of flow velocity before the rack in the surge shaft , the amplitude of stage in the quick gate bay etc . the test step , content and results of different proposals are introduced in details
本项优化试验研究的目的主要在于，通过泄洪系统整体水力学试验，校核泄洪洞的泄流能力；通过发电引水系统整体水力学试验，研究调压井内水流流态和水位波动情况、调压井内拦污栅前流速分布情况；确定快速闸门井内水位波动幅度；试验确定压力管道水击压力穿井系数以及泄洪洞弧形门处的水压力。 - 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。
