摘要
本文以理想绝热过程的气体柏努利方程式为基础.对气流通过渐缩喷嘴的流动状态进行分析和简化,推导出用于气体安全阀的理论泄放量和额定泄放量的计算公式。这些公式与ASMEⅧ-1-1983UG131及其附录11所给出的公式,与GB150-89《钢制压力容器》附录B及《压力容器安全技术监察规程》所采用的公式完全一致。
On the basis of Bernolli equation in ideal adiabatic process, this paper have made analysis and reduction for flow state of gas passing through reducing nozzle and have derived calculating formulas of theoretical and rated discharge capacity for use as safety valve of gas. These formulas are completely consistent with the formulasshowed in ASME Ⅷ-1-1983 UG 131 and its appendix 11,Ones used in appendix B of GB 150-89 《Steel Pressure Vessels》 and 《Supervising Rules of Safety Technique for Pressure Vessels》.
