Abstract: Aiming at the pre-isolation valve system of the atmospheric relief valve in a valve system of Tianwan Nuclear Power Plant,the numerical simulation technology is applied to carry out the numerical simulation of valve opening characteristics.The effect of different structural parameters and different working conditions on the actuation time of the valve was analyzed by CFD method and a theoretical analysis was given for the phenomenon of valve opening delay in the test.With these results the operation characteristics of the air relief valve can be assessed to optimize the valve design.
