【摘要】 通过实验,得到了SPF型平衡阀的流量与开度间的关系,绘制了理想流量特性曲线。在此基础上,分析了SPF平衡阀的调节特性,拟合了SPF型平衡阀的开度、压降和流量间的数学关系式,为这种平衡阀的应用提供了又一种计算方法。更多还原

【Abstract】 Through experiment,achieved the relation of the flux and the opening degree of the SPF balance valve,protracted the ideal flow characteristic curve. Based on the experiment data,analyzed the characteristic of the SPF balance valve,simulated the formulas about opering degree,pressure difference and flow, it was the other calculation method of balance valve to apply.更多还原
