摘　　要：本文综述了已有的有关溢流阀工作稳定性的研究成果 ,介绍了作者对水压溢流阀工作稳定性的研究结果。研究结果表明 :阀芯所受阻尼力和管路的长度或直径是影响直动式溢流阀工作稳定性的重要因素 ;实际应用中还可以通过合理设计与溢流阀相匹配的系统管路来稳定系统压力或减轻系统的压力波动。the research results on operating stability of direct-acting relief valve were introduced. It can be concluded that the restrictive force imposed on the spool and the tube length or diameter are the key parameters which affect the performance of operating stability of direct-acting relief valve. A reasonable designing which results the parameters match between tube and valve can stabilize the system operating pressure and reduce the system operating pressure vibrating.
