| Abstract: | In the paper,the average and fluctuating dynamic loads acting on the butterfly valve in a hydropower station intake pipe are tested and analyzed.The response of flow-induced vibration of the butterfly valve is calculated.The fatigue failure effects of the valve bolt and water hammer action on valve and pipe by sudden closure are analyzed.The investigation results can provide a scientific basis for valve design and safe operation.WaterResourcesandHydropowerEngineeringVol.32No.9 |
