帶導流孔閥門的閘板，無論是全開或是全關始終與密封面吻合，密封面得到保護不受介質直接沖刷，從而延長使用壽命。A mathematic model is first introduced for optimizing the layout of flood - release structures in a high arch dam after an idea of the broad sense of construction costs for unit area gate is introduced, and the optimal computation of the layout of flood - release structures in xiao - wan arch dam demonstrates that this model is reasonable ; 4
在引入了閘門廣義單位面積造價的基礎上，首次建立了高拱壩壩身泄洪建築物布置的數學優化模型，並通過對小灣拱壩壩身泄洪孔口的優化布置計算，說明所提出的數學優化模型是可用的； 4A 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
因拍門簡單、可靠，與虹吸真空破壞截流閉鎖方式相比，可以縮短出水管道（流道）長度，並利於泵系統起動，與快速閘門相比，拍門也有諸多優點，閘門門體易關閉不到位或卡住不能活動，因為門槽和?塊較軸孔容易殘留異物，閘門門體克服滑動阻力不僅無機械增益，且阻力和動力不在一直線上，門體易傾斜而自鎖，而拍門的工作可靠性則遠高於快速閘門。The different drawbacks in the original design and construction of the emergency gate slot of the releasing tunnel of zhelin hydropower station in jiangxi province resulted in the disjunction of most slot corner plates under the parapet walls of two sides of the left hole and the damage of the second - phrase concrete in these slot corner plates, after the gate is closed and under the action of seepage water pressure
江西省柘林水電站泄空洞檢修門槽，由於原設計和施工均存在不同的缺陷，致使閘門關閉后，在滲透水壓作用下，造成左孔兩側胸墻以下大部分門槽護角板被擠壓脫開，護角板裏面的二期混凝土損壞。The flow regime inside of the tunnel, the characteristics of hydrodynamic load, the hydrodynamic pressure feature at the gate slot and the vent air speed during the shutting of the gate is studied through model test, and then the reliability of the gate, the feature of the vent air speed and the pressure at the gate slot during the shutting of the gate are analyzed based on the test result concerned
通過模型試驗研究了事故閘門關閉過程中泄洪洞內的水流流態、門體的水動力荷載特性以及門槽段動水壓力特性、通氣孔風速，並根據試驗結果分析了該閘門動水下門過程中的可靠性，通氣孔風速特性和門槽段壓力特性。The load experiments on using the hoist for the plate sluice gates to lift the arch sluice gate
