摘要： 为提高换向器的性能和减小不确定度，在分析换向器结构、换向过程、不确定度影响因素的基础上，提出了一种步进电机直接驱动分水器旋转换向的电动换向器结构，利用PCI板卡控制其旋转换向动作，在不同流量点可采用不同速度，具有较好的正反行程的对称性.研究了换向器的控制策略，设计搭建了多口径的换向器测试平台，进行了DN50，DN80口径换向器的行程差法实验测试.实验数据表明，电动换向器的不确定度可达到0.0012%的水平.这种结构降低了运行时的噪声，提高了不确定度的水平，进而可以降低液体流量标准装置的整体不确定度.

Abstract: In order to reduce uncertainty and improve performance of flow diverter, on the basis of analyzing the structure of the flow diverter, the process of transfer and the factors impacting the uncertainty, a structure of electric flow diverter was put forward. A step motor directly drove the water separator to turn and realize the direction convert. The action of turning and direction convert was fully controlled by PCI cards. It could work at different flow point with different rate and had a good performance on the symmetry of forward and reverse process. The control strategy of the electric flow diverter was also investigated. A test bench for multi-caliber flow diverter was designed and built. The experimental tests of DN50 and DN80 flow diverters were carried out. It suggested, by the test data, the uncertainty of the electric flow diverter could reach 0.0012%, which could reduce the uncertainty of the diverter and noise. It will eventually reduce the overall uncertainty of liquid flow facility.
