System suitable for flow display and speed measurement in closed flow channel

The invention relates to a system suitable for flow display and speed measurement in a closed flow channel, which comprises a flow display device and a speed measurement device, and is characterized in that the speed measurement device comprises an organic glass sealing device, a pitot tube, a handheld micromanometer and a rubber pipeline; the flow display device comprises a rubber plug, an injector, a dye box, a sharp-nose bottle, a capillary tube, a rubber tube, a steel elbow and a sealing device. Compared with the existing closed flow channel detection technology, the system can detect the flow velocity distribution of the throat part of the pump pipe in the closed flow channel, and improves the accuracy and convenience of flow display of the water inlet pool. 本发明涉及一种适用于密闭流道中流动显示及速度测量的系统，包括流动显示装置和速度测量装置，速度测量装置包括有机玻璃密封装置、皮托管、手持式微压计、橡胶管道；流动显示装置包括橡胶堵头、注射器、染料箱、尖嘴瓶、毛细管、橡胶管、钢制弯管、密封装置。相较于现有的封闭流道检测技术，本系统可以测出封闭流道内泵管喉部的流速分布，提高进水池流动显示的精确性及便捷性。
