摘　　要：对于无隔热气瓶,如果不考虑外界介质注入及内部化学反应引起的超压,此类容器超压基本是外界温升或火灾引起的气体、液体膨胀所致。对美国CGA S-1. 1无隔热压缩气体气瓶泄放量计算公式进行了推导,确定了压缩气体及液化气体泄放量与泄放面积计算公式,并与GB/T 33215-2016中泄放量计算公式进行了比较,提出了采用GB/T 33215-2016标准计算公式存在的问题,为标准修订提供参考。The overpressure of uninsulated cylinder is mainly caused by gas or liquefied gas expansion due to the environmental temperature rise or fire without inpouring of external gas and chemical reactions in the cylinder. In this paper,the formulas in CGA S-1. 1 for calculating safe relief capacity and relief area of uninsulated cylinder for compressed gas and liquefied gas are derived and are compared with that in GB/T 33215-2016. The existing problem existing with the formula in GB/T 33215-2016 is put forward,which provides reference for revision of this standard.
