Paper Details

Valve is a mechanical component that regulates the flow of fluids by opening, closing or partially obstructingvarious passage ways. Gate valve is one of the type of flow control valve, which controls the flow of fluid in the form of awedge or disc. The hot blast valve which is the modified form of a gate valve of DN1800, with the gate in fully closedcondition. The Effect of pressure locking is an important phenomenon for the design of a hot blast valve. Due to this effect themost critical components of the hot blast valve gets effected like the valve body, bonnet, disc, etc. In this paper investigationis done on the disc plate which has the major effect by the pressure locking. In order to make the design safe from thepressure locking phenomena a static analysis is done on the disc both theoretically and numerically. In theoretical analysisthe disc plate was designed using the plate theory and the stresses and strains were calculated. In numerical analysis themodel is generated in CREO3.0 and analysis done in ANSYS Workbench. The results obtained from the theoretical andnumerical analysis were compared and the redesign of the disc plate at different thickness is done. The results obtained werecompared to select the best thickness of the disc plate, which tries to reduce the effect of pressure locking phenomena causedby the closing of the valve while operating.
