【摘要】：通過對錐閥在不同錐角、不同閥口開度及不同壓差條件下的速度場和壓力場進行分析,類比電路基本理論,得到了在不同壓差條件下壓力及速度梯度變化的規(guī)律,并分析了錐閥閥口的能量損失規(guī)律;與此同時分析錐閥閥口渦流產生的原因,通過對閥座結構進行改進,以減少渦流大小,從而達到降低能量損失的目的,為錐閥的設計提供了理論參考依據。
[Abstract]:By analyzing the velocity field and pressure field of cone valve under different conical angle, different opening degree of valve and different pressure difference, the variation of pressure and velocity gradient under different pressure difference conditions is obtained by analogy with the basic theory of circuit. The law of energy loss is analyzed. At the same time, the causes of swirl at the orifice of conical valve are analyzed, the structure of valve seat is improved to reduce the eddy current size, and the energy loss is reduced, which provides a theoretical reference for the design of conical valve.
