摘要：This article aims at the problem that the difference in the flow field performance of the valve cavity after the overflow valve is installed with the eddy current sensor. The structural optimization of the valve core and seat and a research method to improve the flow field performance of the valve cavity is proposed by analyzing the influence of the structure of the built-in eddy current sensor probe on the flow field performance of the valve cavity. First, the flow field analysis model is established, to analyze the flow field of the built-in probe structure. Then, the influence of the valve core micro modeling, valve seat flow path diameter, gradient line chamfer depth on the flow field performance of the valve cavity is analyzed. The results show that the structure of the valve core and the valve seat have been optimized and the flow field performance of the pilot valve cavity of the overflow valve can be improved to a certain extent.
