摘要

Seawater butterfly valve for nuclear power requires good overflow performance and open-close characteristics, and analysis on the flow pattern of internal field was conducted. A finite element model was constructed using Fluent software, and the model was applied to predict the characteristics of the designed valve flow field for disk positions ranging from 5 degree to 90 degree. The relationship between flow coefficient and disk positions was constructed, as well as the relationship between flow coefficient and disk positions. Simulation results verified the overflowing property of seawater butterfly valve satisfies the requirement of inlet and outlet butterfly for steam condenser.
