浅谈流量系数可调小流量阀门的设计及性能研究

Key Points

• The central aim is to address technical limitations in conventional small flow valves such as narrow CV adjustment range and low accuracy.
• Proposed a dual-guided structure with a multi-stage adjustment surface for the valve design.
• Optimized valve core structural parameters, implemented non-media unbalanced force design, and integrated intelligent control algorithms.
• Conducted flow field simulation analysis using CFD with k-ωSST turbulence and cavitation models.
• Achieved precise CV value adjustment between 0.001 and 0.05.
• Improved flow adjustability ratio to 200:1 and significantly enhanced stability and reliability compared to traditional small flow valves.
• Effectively suppressed cavitation and reduced flow-induced vibrations.
