一种流量阀几何形状设计计算方法

本文推导了提动头式和滑阀式窗口形两种典型调节阀的理论型面线通用坐标方程,在给定A=f(m)的函数关系后,即可计算表达该阀几何形状的曲线方程,从而求得调节阀的精确的几何尺寸。并讨论了为便于加工,型面曲线用直线近似的方法和误差的校核。

The Design and Calculation Methods of the Geometry of a Flow Valve

The paper derived the general equations of the theoretical contour elements for the two typical valves, the lefting moving head type and the slide window-shaped type of valves. Given the functional relation of A = f(m), then the equations of curves can easily be obtained to express the geometry of the valve, hence its accurate contour element can be drawn. For the ease of workship, the approximation methods to select a straight line to substitute a curve and how to check the errors are discussed. The calculation and design methods offered in the paper can, be carried out by utilization of modern calculating techniques.
