In order to study the flow character of the labyrinth type regulating valve,CFDmethod was used to simulate the inner flow field,and the pressure distribution and velocity distribution in the flow field were obtained.The flow coefficient and the flow character were computed.The simulation result shows that the construction of labyrinth channels can reduce pressure evenly,and the flow character of the regulating valve is linear,whichmeet the desired goal.
