摘要
为了满足船舶航行和停泊条件,用改变阀门操作规律的方法,使船闸输水不稳定流量变为长时间稳定流量。给出梯形流量过程线情况下阀门开启面积变化等计算公式。本文研究结论应用于船闸中间渠道试验中,得到了满意的效果。此外,反弧形阀门试验表明,由于将最大流量减为较小的稳定流量,对阀门工作条件也有利。
In order to satisfy the vessel navigating and mooring conditions, the author tries to turn the traditional unsteady discharge into a long-time steady disc harge of the filling and emptying of a lock by the means of changing the operational characteristics of the valve. The formulas are also discribed for calculating the variation of the valve operation area for the trapezoidal discharge hydrogragh.This study result was applied to the test of the intermediate canal between the lo cks and a acceptable result was obtained. Eurthermore, it is shown from the model test on the reversed tainter valves that reducing the maximum discharge to the small steady discharge will be beneficial to the working conditions of the valves.
