平面闸门的止水橡皮在闸门启闭过程中因为同门槽摩擦而易破损,导致漏水。笔者通过模型试验研究设计出一种斜面闸门,它能够解决止水橡皮被磨损的问题。现将斜面闸门减少止水摩损的原理简述如下。斜面闸门是由闸门构架、斜面门叶、定导轮及启闭杆等部件组成(见图1),与平面 Flat water gate rubber gate in the process of opening and closing the door because of friction and easy to break, leading to water leakage. The author designs a kind of slant gate through the model test and research, which can solve the problem that the water stop rubber is worn. Now slant gate to reduce the principle of water stop loss is as follows. Inclined gate is composed of the gate structure, bevel door leaf, guide wheel and the opening and closing rod and other components (see Figure 1), and the plane
