英文摘要	Taking the flow field of Nitrogen-type surge relief valve for research subjects, immersed solid method was used to simulate the opening and closing process of nitrogen-type surge relief valve, the 3D models of uid domain and immersed solid domain were established, the kinetic equation of valve core were established by using the valve core trajectory, Aiming at the special design for the unequal area of valve cone, the forced state of respective end face in the opening and closing process of relief valve under the effect of surge uctuations pressure were contrasted, and the influence law of the force of valve core respective end surface and the capacity of discharge in different constant pressure and the effect of surge uctuations pressure of relief valve inlet was analyzed. The results showed that the movement of valve core in the opening and closing process was a concussion process, unbalanced force was existing, the force of valve core respective end face was uneven, and the concussion of all of them were in the opposite directions and different amplitude, the force of valve core cylindrical surface can be ignored. © 2017, Science Press.
