Özet
Butterfly valves get this name because the visual of their working principle resembles the wing movements of a butterfly. In this way, flow control is more ergonomic, and it becomes possible to save water. However, in addition to these advantages, the difficulty of minimizing flow resistance is observed as a disadvantage. The costs of design improvements made in valve products, which are produced by the casting method and involve labour-intensive production stages such as assembly and welding, are quite high. In these cases, computer-aided design and test simulation become more important. In this study, the designs of the products were carried out by using computational fluid dynamics and finite element methods. Details of the simulations and design verification stages were included, the designs were made with Solidworks and these data were validated by ANSYS. As a result of the study, a body and ring designs were achieved with an improvement of 26% compared to existing products and 32% compared to the industry average. Finally, national and international patent applications have been made for the unique curved body and gradual shaft designs obtained during the development phase of the product.
