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。
According to the relevant provisions of JB / T 5296-91, two structures of the globe valve differential pressure-flow relationship was tested. Through the hyperbolic regression test data to calculate the two kinds of structure of the valve in a variety of opening flow resistance coefficient, and draw the pressure - flow and flow resistance coefficient - opening relationship.
