Abstract
Butterfly valve is a kind of rotational valve which opens and closes the flow of fluid on rotating the disk 90 degrees in the valve body. In this paper, butterfly valve design safety evaluation which is based on the international valve specifications is investigated. Both body and disk of the butterfly valve are considered under the normal and pressurized operating conditions. A finite element analysis is carried out to compute the distribution of the displacement, stress and safety factor by using ANSYS. On the basis of calculated design safety we offer the design modification and compare with them.
