Study on Internal Flow Characteristics of Large Diameter Piston Valve in the Yangtze-Hanjiang River Diversion Project
In the feasibility study stage of the Yangtze-Hanjiang River Diversion Project,it is proposed to use a large di-ameter piston valve as the flow regulating equipment for the pressurized self flowing water delivery system.The water flow field and the hydraulic characteristics of differant discharges inside the piston valve are analyzed based on CFD software numerical simulation.The Q-H characteristic curve and valve opening water loss flow curve of the piston type valve un-der various design conditions are obtained.The numerical simulation results indicate that large-diameter piston valve can meet the flow regulation requirements for this project.
