According to the requirement of low energy consumption and high efficiency of a three-way regulating valve used in a system, based on the CFD software of fluid mechanics, the internal flow performance of the three-way regulating valve was simulated and studied in three dimensions, and the flow field information such as internal pressure and flow velocity of the valve were obtained. The results show that with the increase of the opening degree, the pressure gradient and velocity gradient at the upper valve seat gradually tend to be obvious, the pressure drop at the valve seat and the maximum flow velocity at the sealing surface gradually tend to be extreme, while the change rule at the lower valve seat is opposite. When the valve works under extremely small and extremely large opening conditions for a long time, it will be beneficial to protect the valve.
