Liquid level control value is widely used in the process industry to control internal liquid height as pipe flow control component. During the operation of the liquid level control valve, the force condition of the value core directly affects the stability of the valve works. Therefore, it becomes the important factors in the design of the spring components of the liquid level control valve. In this paper, the internal flow field of the automatic control valve during closing process is simulated by using Fluent CFD software. The numerical simulation results show that in the process of closing the automatic control value, the water hammer phenomenon will be occurred at the beginning stage. With the continuation of the valve closing process, the pressure in upper chamber of the value core and internal chamber are rapidly reduced and tend to be gentle, while the pressure difference increases gradually. What is more, the flow of throttle gradually increases, and the inner chamber of the valve core appears small disturbance. These conclusions provide a theoretical basis for the technical design and improvement of the control valve.
