Lightweight Design of Valve Body Structure Based on Numerical Simulation

In order to save costs and protect resources, and improve the green level of valve body design, a numerical design method was used to lightweight the valve body structure for an electric gate valve being developed by S Company. The original square valve body structure was designed as a cylindrical structure. SolidWorks was used to model the valve body structure in three dimensions. The flow simulation was used to perform flow path extraction and flow field analysis on the valve body. Fluid–structure interaction analysis was performed on the optimized valve body, and mechanical performance analysis was performed. The analysis results show that the mass of the valve body is reduced by 728 kg, the optimization rate is 20.8%, the allowable stress requirements are met, and the lightweight design of the valve body is OK.
