PRESSURE LOSS ANALYSIS IN THE STEAM TURBINE CONROL VALVE

Abstract

: Pressure loss analysis is carried out in the sub parts of the control valve. Attention is devoted to the pressure loss on protective strainer, to the pressure loss in valve chamber and in the diffuser. The influence of the flow vortex under the cone on the loss in the diffuser is analysed. The flow in the valve is considered for specific operational characteristics of the turbine.
