Analysis of internal flow characteristics of geometrically compensated jet control valve

In view of the serious erosion and wear of the existing control valves under small opening, it is difficult to meet the requirements of the equipment system. The internal flow field of the newly developed jet control valve was numerically simulated by using computational fluid dynamics software. The distribution law of the internal pressure field and velocity field of the control valve with different opening degrees was studied, and the comparison with common rotary valves was made.The results show that with the increase of the opening, the flow performance of the jet valve is more stable, and the maximum flow velocity is concentrated in the center of the basin, which avoids the eccentric flow wear and erosion on the valve body and the pipeline behind the valve, overcomes the defects of the existing rotary valves, and ensures the long-term safe and stable operation of the system.
