摘要：
Based on the homogeneous equilibrium flow model, the cavitation model and the DPM model, the simulation and prediction of the gas-liquid-solid multiphase flow in the cage-typed control valve are carried out, and the distribution of erosion wear and cavitation in the valve is analyzed. Combined with the actual failure situation of the cage, the analysis results were verified and the main reason for the failure of the cage was determined. The results showed that the main areas of cavitation in the valve were located in the inner orifice of the valve cage. With the increase of the valve opening, the vapor volume increased, the number of orifices through which the fluid flows increased, the cavitation range and intensity also increased. Due to the high-speed impact of particles on the inner wall of the diversion groove, there were obvious deformation and penetration defects in the center and surrounding areas were directly impacted by the particles. The areas with the highest erosion wear rate under multiple openings were located on the inner wall of the guide groove away from the valve inlet side. The pit-like defects around the outlet of the orifice in the inner wall of the cage were mainly caused by the collapse of the cavitation bubbles and the impact on the wall. © 2023 Chemical Industry Press.
