The many parts in the hydraulic equipments subject to load by hydraulic pressure. And some parts which are installed to the inside of the hydraulic equipments subject to load by the hydraulic pressure as well as the fluid speed. The inside of the valve generally generates the flow. Considering the valve expansion or the flow of the large valve, the flow is similar to the fluctuation flow in the opened flow system. In this study, the analysis of the flow including the fluctuation are performed and this results will apply to the optimal shape design of the flow path. The load acting on the structure was analysed according to the change in the shape and flow speed of the structure which install in fluid, and the safety evaluation wad investigated in consideration of the flow speed and the depth of fluid.
