Abstract：In order to get the hydraulic performance of surge anticipation valve on water hammer protection, the mathematical models of pump and surge anticipation valve were established. Effects of 5 closing characteristics of surge anticipation valve on water hammer process in a pumping station at Ningxia Guyuan area were analyzed by means of method of characteristic. The results show that the water leakage reaches maximum when the surge anticipation valve with needle valve type is in fully open. The flow decreasing rate through the valve is approximately equal to the valve′s opened area decreasing rate in the closing process of the valve. The pressure surge at the outlet of pumping station tends to reach a new steady state rapidly if the surge anticipation valve with butterfly valve type is adopted. It also turns out that when the closing characteristics of surge anticipation valve is from increasing dece-leration to decreasing deceleration, the highest pressure values tend to decline and the lowest pressure values tend to increase for the entire system. Therefore, better water hammer protection effect is obtained with the closing characteristic as decreasing deceleration.
