Impact of Valve Closing Time on Water Hammer Effect Considering the Comprehensive Factors of Pipeline Length and Flow Velocity
This paper conducts an in-depth analysis of the water hammer phenomenon in liquid pipeline systems in the petrochemical industry.Using the SPS software and the method of controlling variables,320 different working conditions were calculated and analyzed for combinations of 8 flow velocities,5 valve closing times,and 8 pipeline lengths to assess the impact of these factors'interaction on the maximum water hammer pressure before the valve.The results indicate that as the pipeline length increases,the effect of reducing water hammer pressure by extending the valve closing time gradually diminishes.In design work,it is essential to consider the impact of pipeline length and medium flow velocity,and to upgrade the pipeline's pressure class or take other protective measures when necessary.
