Large scale gate valves are widely used in industries such as mining,metallurgy,and petrole-um due to their low flow resistance,high reliability,and long service life.However,the main valve body cavity of large-sized gate valves is large and the cross-sectional shape is irregular,making it difficult to accurately calculate the strength according to traditional design methods,resulting in overly conserva-tive valve design and defects such as high cost and low efficiency.This design utilizes CAD technology to improve large wedge gate valves,increase material costs,rationalize layout,simplify manufacturing and assembly,and improve finished product efficiency.Through Ansys finite element analysis and Au-todesk Inventor 3D modeling,the optimized valve body and gate stress can be reduced by 4.26％and 15.83％respectively,significantly reducing valve weight and cost,providing reference for large-diam-eter valve design.
