本文对直流阀中有关气流压力分布规律的两种假设作了评述。通过测定不同结构参数直流阀的推力系数,提出了阀中压力分布曲线的近似模型;探讨了理想分布规律的条件;为一般直流阀提供了确定推力系数的无因次曲线图。
This paper reviews two hypotheses about the distribution of pressure in a direct flow valve. The approximate model of the pressure distribution curve in the valve was proposed by measuring the thrust coefficient of the DC valve with different structural parameters. The condition of the ideal distribution was discussed. The dimensionless coefficient of the thrust coefficient for the common DC valve was provided.
