Abstract: A suddenly pump stop in multi-pump parallel connection system could induce water hammer which may cause serious accidents. To prevent water hammer harm, comparing experiments was carried out to study the water hammer phenomenon in the lift closing check-valve adopted system and the shuttle check valve adopted system. The result indicates that, the shuttle check valve greatly cuts the peak-value produced by stop-pump water hammer impulsion, and reduces the probability of bringing a devastating water hammer accident.

Abstract: To research the flow field characteristics in the shuttle check valve, this paper adopted numerical simulation and contrast method. Based on ADINA, it respectively implemented geometric modeling, parameter setting and fluid-structure interaction calculation on the shuttle valve and the swing check valve. By analyzing visualization results, it derives that the former has the advantages of uniform velocity distribution, steady flow state, equilibrium load on the valve core, etc. compared with the latter in the process of opening, thus providing data basis for optimal design of the shuttle valves.
