摘　　要：介绍了直动式电液比例溢流阀的结构特点、静动态模型及实验研究,理论分析与实验结果一致,为阀的优化设计提供了理论基础。采用压力反馈及前向通道的PID调节,有效地提高了阀的静动态特性。The paper describes the structure and static and dynamic characteristics of the direct acting relief valve. The theoretical analysis is in accordance with experimental results, which can provide a theoretical basis for optimization design. The static and dynamic characteristics can be improved by a pressure feedback and PID regulation in the forward path.
