Optimization of gate valve structure based on strength parameters using finite element analysis

The application of a gate valve is to make a straight-inline flow of fluid with less restriction as the turbulence is created through the aperture provided in the valve body. The change in direction of the fluid creates change on the operating stress of the vale body. The paper is targeted for designing the valve body for reduction in the overall weight of the body and making it light in weight. The optimized design keeps the operating stress with operating stress within change of 5% which thereby ensures that the original stress value is not altered much. In the current manuscript the ribs of various thicknesses are proposed those are to be welded across the outer periphery of the body. The ribs provided on the periphery are substitutes for the reduction in the weight. The sensitivity analysis along with the change in the materials is analyzed in the manuscript. The complete optimization is valve body is done by topology optimization tool in ANSYS. This paper help and give an aim for researchers on optimizing the gate valve body with help of finite element analysis (FEA) and optimized design by adding ribs to the gate valve body to reduce the stress and deformation.
