小型水库塘坝的简易闸门与小型水库放水清淤闸门适用范围:灌水面积小于四万亩的灌区,即夏季作物与秋季作物均小于二万亩的灌区或明流过水洞的过水能力在0.2—2秒立米者,均可采用定型的截锥体简易闸门,见设计图。1、过去大型平板闸门的缺点1、巴盟明流放水洞过水能力很低一般变化在0·2——2秒立米之间以往在库容较小的水库上有的采用了大型平板闸门,招致闸门的开启度很小,橡皮止水在高速的水流 Small gates and small reservoirs in a small reservoir Dredging gates for water discharge Scope of application: The irrigated area with a water area less than 40,000 mu, that is, the irrigated area with less than 20,000 mu of summer crops and autumn crops or the water flow capacity of the Mingliu water-passing holes is 0.2 -2 seconds meters, can be used stereotypes simple truncated cone gate, see the design. 1, the shortcomings of the past large-scale flat-panel gate 1, Bameng Ming drip hole low water capacity is generally low in the 0-2-2 seconds between the previous reservoirs in the reservoirs with some large-scale flat gate, The opening of the gate is very small, rubber stop water at high speed
