摘　　要：本文中作者提出了一种新型压力释放阀,以同步提升泄放能力及阀体强度。首先基于新阀设计概念提出四种具体方案,然后对不同方案展开隐式静力学及显式动力学分析,最后对比了仿真结果。仿真结果表明阀盘开启至最大开度时间随阀盘质量增加、弹簧刚度增大而延长。试验结果表明新阀能良好可靠应对高能电弧故障,所研制新阀可用于电网系统。仿真数据与实验结果良好匹配,所建显式动力学仿真模型可指导压力释放阀优化设计。In this paper,the author proposes a new pressure relief valve to simultaneously improve the relief capacity and the strength of the valve body.Firstly,four specific schemes are proposed based on the new valve design concept,and then the implicit statics and explicit dynamics analysis are carried out for different schemes,and finally the simulation results are compared.The simulation results show that the required time for the valve disc being fully opened increases with the increase of the valve disc mass and the spring stiffness.The test results show that the new valve can cope with highenergy arc faults well and reliably,and the developed new valve can be used in the power grid system.The simulation data matches the experimental results well,and the established explicit dynamic simulation model can guide the optimal design of the pressure relief valve.
