摘要
根据ＪＢ／Ｔ ５２９６－９１的有关规定，对 ２种结构的截止阀压差一流量关系进行了测试。通过对试验数据进行双曲回归，计算出２种结构阀门在各种开度下的流阻系数，并绘制了压差—流量及流阻系数—开度关系图。
Based on the requirements of JB/T5296-9l, the testing methods of universal valve flux coefficient and flow resistance coefficient, the relation of different structure is in- vestigated. The flow resistance coefficients of two types of valve under various jaw opening conditions are calculated through hyperbolic regression on experimental data, and the relation curves of differential pressure versus flux and flow resistance coefficient versus jaw opening are drawn with GRAPH TOOLS.
