| Popis: | Many industries including power-plants, refineries and so on are using high pressure control valves. Many of these valves have traditional geometries like butterfly valves. Unfortunately, because of the special design of these valves, cavitation causes very rapid corrosion. In the last decade, a next generation of control valves have been introduced which are designed to prevent cavitation. Because of the special fluid paths in the Labyrinth valves, the pressure drop is very graduated which prevents cavitation. In this article, the geometry of fluid path is optimized using Taguchi method. To this end, four parameters are considered including path's height, number of corners, corner radii and input area. For each parameter three levels are assumed and using a standard Taguchi array the optimum geometry is predicted. Then the pressure drop in optimum geometry is simulated using finite element method and the results validated the optimized geometry. |
