NUMERICAL SIMULATION OF PLUG VALVE DESIGN PARAMETERS AS PER STANDARDS

Valves are mechanical devices specifically designed to direct, start, stop, mix, or regulate the flow, pressure, or temperature of a process fluid. Plug Valves are commonly used as fluid flow control equipment in many engineering applications. For designing the Plug Valve it is essential to know the numerical calculations involved in getting the basic design parameters like fasteners size, wall thickness etc., This paper describes the modeling and simulation of the plug valve using ANSYS and the results are compared with numerical equations which are required for basic design parameters of plug valve such as Wall Thickness, Torque Calculations, Stem diameter calculation and fastener calculations. It also includes three-dimensional numerical simulations conducted using the CAD tool to facilitate further changes to geometry. Obtained results not only provide the designer with the access to understanding the steps involved in getting basic design parameters of the plug valve but also helps to determine the appropriate methods to design the Plug valve. Furthermore, the results of the three-dimensional analysis can be used to find the Fluid flow inside the plug valve and in design optimization of valve torque.
