| Abstract: | The flux character of minimum flow regulating valve is researched,simulated the high differential pressure condition by methods of digital simulation. The simulation results show that the construction of labyrinth channels can reduce pressure evenly,and increase flow resistance coefficient to reduce the possibility of cavitation. The research provides theoretical basis for guaranteeing the long life and reliability of the valve. |
