摘要:简单介绍了安全阀开式和闭式泄放系统的静态当量计算方法,对于闭式系统,排放达到稳态流之前冲击波会在管道系统中传播,为了能够定量的进行计算,引入了不平衡力的概念,介绍了闭式系统中不平衡力的计算方法和管道系统为什么会出现自平衡性的原因。采用时程分析方法对闭式系统排放达到稳态流之前的过程进行了较精确的计算,对管道系统的这一自平衡过程进行了验证。

Abstract:This paper briefly introduces the static equivalent calculation method of the open and closed release system of the safety valve, For the closed system, the shock wave will propagate in the pipeline system before the discharge reaches the steady flow. In order to describe this process, the concept of shaking force is introduced and explains why the piping system is self-balancing. The time-history analysis method is used to calculate the process before the steady-state flow and the self-balancing process of the pipeline system is verified.Key words:safety valve;closed discharge system;time history
