摘　　要：为了解决2D电磁换向阀(以下简称换向阀)测试中,流量检测复杂、试验成本较高的问题,采用磁旋转编码器AS5045完成换向阀中转轴的角位置检测。通过分析换向阀结构及工作原理、磁旋转编码器原理及调理电路,理论计算出转轴角度与流量的关系。比较实测流量值与计算流量值,在误差允许的范围内,二者几乎一致,得出结论:在不具备检测换向阀流量的工况下,可通过检测换向阀旋转角度的方法判断换向阀的输出流量是否满足要求。此方法操作简单,经济可靠。In order to solve the problem of complex flow test and high cost in the test of 2 D electromagnetic directional valve, the magnetic rotary encoder named AS5045 is used to complete the angle position test of the 2 D electromagnetic directional valve. The relationship between the angle of rotating and flow is obtained by calculating and analyzing of the structure and working principle of 2 D electromagnetic directional valve and the principle and conditioning circuit of the magnetic rotary encoder. The conclusion is that the output flow of 2 D electromagnetic directional valve can be judged by detecting the rotary angle of 2 D electromagnetic directional valve, there is not available the flow of 2 D electromagnetic directional valve by compareing of the measured flow value and the calculated flow value in the range of error allowed. This method is simple,economical and reliable.
