| 摘 要： | 对半圆形、单三角形、三角半圆形和双半圆形节流槽阀口的流量系数进行了研究。基于阀口的流量压差特性试验，在已实现程序化计算阀口通流面积的基础上，获得了上述4种节流槽阀口的流量系数及其变化规律，对节流槽滑阀的设计及其流量精确预测具有重要实用价值。

| Abstract: | It analyzes the flow coefficient of semicircular, single triangle, triangle-semicircular and the double semicircular notches. Based on the experimental of discharge and difference pressure, it obtains the programmed calculation of notches, the flow coefficient and its variation of the above notches. This study has some value for the spool valve design with notches and accurate prediction. |
