Analysis on dynamic water closing test of butterfly valve for hydro-power unit in Baishan Pumped Storage Hydropower Station

The dynamic water closing tests are respectively made on the butterfly valves for two hydro-power units in Baishan Pumped Storage Hydropower Station,so as to test the reliability of the closing of both the butterfly valves for the units therein under the dynamic water condition and obtain the closing law and the stability parameters of the valve bodies during the closing,and then to determine the safety factor of the closing for the valves;for which the result of the experiment analysis is given herein as well.
