英文摘要	Aiming at the problem of low flow control accuracy of the dynamic flow balance valve, based on the orifice flow and concentric annular gap flow equations, the spool opening profile was initially designed, and the pressure difference compensation coefficient factor correction method was proposed to optimize and modify the existing profile formula. Based on the large eddy simulation (LES) turbulence model, the flow control accuracy and flow accuracy error of the dynamic flow balance valve before and after optimization were studied by numerical simulation, the influence of the valve core opening profile on the pressure pulsation intensity was compared and analyzed, and a flow test bench was built to verify the proposed optimization method. The results show that the pressure difference compensation factor correction method to optimize the spool opening profile can effectively reduce the pressure pulsation intensity of the spool end face, and improve the flow control accuracy of the dynamic flow balance valve to 3.7%. The flow field simulation calculation and the experimental results basically coincide with the trend. © 2021, Editorial Board of Journal of Harbin Institute of Technology. All right reserved.
