On the basis of analyzing and studying on the former test results of hoist load of reverse tainter valve which is the main type of valves for navigation locks, a large scale (1:16) physical model for YinPan lock culvert valve has been built. Through the steady and unsteady flow experiments, structure of the acting flow on the valve has...更多been observed and analyzed in detail. It has been found that the valve's net hydrodynamic hoist load can be composed of two parts, one is the acting force result from water in culvert and the other result from the descending and rising flow in valve well. Furtherly the formula of the net hydrodynamic hoist load has been put forward by theoretic analysis, and the calculation results has been proved to be agreed well with the experimental results. Meanwhile, the factors affecting the net hydrodynamic hoist load and their changing laws have been further studied. The further research direction is also been pointed out.
