Hydrodynamic Studies on Spherical Valve

The paper emphasizes the theoretical aspects of spherical valve operation, the calculation of hydrodynamic parameters specific to this type of valve and a method of analysis of the influence of the main physical-mechanical parameters of flow simulations using specialized software. It may reveal such power distribution lines for different opening angles of the valve and pressure distribution along the flow speed and hence can express losses coefficients and flow coefficients. Areas with whirlpools and a large cluster of vortex lines characterize significant losses of hydraulic energy along the flow and can lead to structural characteristics that provide optimal design of these valves.
