Abstract
Based on the theory of fluid transient flow,the phenomenon of water hammer is explained,and the causes of its occurrence are sum-marized.On this basis,through the experimental simulation research method,extended valve closure time method and the two-stage closing valve scheme are adopted to study the protective measures of water hammer.It is found that both schemes can effectively reduce the maximum pressure generated by the water hammer,and properly extend the closing time of the two stages,can more effectively reduce the harm of the water hammer.关键词
