Notes:
The safety valve has been designed to protect high pressure vessels. A fracture plate madeof a circular thin plate is located within the safety valve. The circular thin plate has an outlet for fluidrelease and to help decrease the pressure. As such, fracture of the circular thin plate can occur at theappointed pressure. In this study, design variables of the safety valve were used to control fracturepressure so that it was easy to apply in the development of a new model of a safety valve. Designvariables were fluid diameter of the safety valve, thickness of the fracture plate, filet radius of theclamping bolt, fracture pressure, and clamped torque of the clamping bolt. Design variables wereselected, since the fracture experiment indicated that these variables might play a critical role in thefracture of the circular thin plate. Fracture pressure was calculated by the finite element analysismethod and analyzed to affect the design variables on the fracture pressure. Using regression analysis,main design variables such as the fluid diameter, the thickness and the fillet were selected and therelationships of the variables were expressed by a regression equation. Furthermore, finite elementanalysis method and the regression equation were verified comparing with the experiment result
