Analysis of Flow Characteristics of Regulating Valve Based on CFD Simulation
Regulating valves have been widely used in fluid conveying systems.The regulating valve with valve cage is different from the traditional regulating valve,its fluid flows out through the valve cage,and the flow shape and area of the valve cage play a crucial role in the flow characteristics of the regulating valve.In order to study the Computational Fluid Dynamics(CFD)simulation technology,the valve model is established and the valve cage is numerically simulated.The results show that increasing the flow area of the valve cage is helpful to reduce the pressure difference between the inlet and outlet of the valve.The results show that increasing the flow area of the valve cage is helpful to reduce the pressure difference between the inlet and outlet and the polygonal valve cage can also help reduce the pressure difference of the valve.The polygonal cage also helps to reduce the pressure difference between the inlet and outlet of the valve.This study provides an important theoretical basis for the structural design and optimization of regulating valve cage.
