Abstract
In a system with the 3-way regulating valve, low energy consumption high efficiency based on fluid dynamics CFD software, for the 3-way regulating valve of the 3 d simulation for internal flow property research, obtained the pressure within the valve flow turbulence kinetic energy and turbulence dissipation rate etc. The results show that the flow field information with the increase of the opening, the seat area on the turbulence kinetic energy and turbulence dissipation rate increases sharply, change law instead of the seat position. The existence of transition cone can greatly reduce the turbulent kinetic energy and the turbulent dissipation rate of the upper seat in the wide opening range and the valve in the small opening range. Long-term avoidance of the valve working in the minimum-opening condition will be beneficial to the protection of the valve.
