An oscillating valve or non-return valve is a type of check valve used at the inlet of high pressure boilers. The valve allows the flow only in one direction, ie the boiler from the pump. The basic design of the valves was developed by Toa Valve Corporation of Japan and is now manufactured and used in 500 MW power plants by BHEL India-India's largest and largest heavy electric manufacturer.
The paper-a mini project elucidated mainly on the design and analysis of 500 MW size 450 mm and 2500class swing valve using ANSYS workbench. The designs were based on ANSIB16.34. Then, using the maximum voltage values and Safety Factor, a new BHEL Trichy project was designed and designed with PRO-E Wildfire. then the maximum voltage values were analyzed and calculated. From the result, to optimize and reduce the pressures for higher pressures, the thickness was increased and the design was modified. The equivalent voltage values of both valves were found to be below the allowable stress limit of the material. The same 3D model was analyzed and supported by results also from ANSYS.10. The project also sheds light on the specifications of the new valve. In this project some modifications were made such as the sharpening of the sharp edges inside the valve and the reduction of weight.
