- 摘要:
- 针对自主研制的大流量气体减压器,建立了减压器工作过程的数学模型。采用 四阶龙格一库塔法进行数值仿真,分析了减压器在下游阀门打开过程中的响应特性,仿真结果和 试验结果一致。在此基础上用仿真的方法分析了主要结构参数对响应特性的影响规律。
- Abstract:
- A dynamic mathematical model for large flux pressure reducing valve(PRV)was developed in this paper.Four—step Runge—Kutta method was adopted for numerical simulation anal— ysis of the PRV’S responding characteristics.Good consistance was obtained between the experimented results and the computed ones.Based on these results the influence of the main structure parameters to the responding characteristics were analysed in this paper.
