摘要
本文对目前气瓶设计存在的常见问题进行了总结归纳,归纳出的问题主要有设计文件内容不完善、设计属性和鉴定属性定义不明确、"同一设计、系列参数"设计不规范以及材料强度保证值取值、最小爆破压力计算、低温绝热气瓶最大充装量计算、阀门设计、纤维缠绕气瓶缠绕层选材几个方面,对每个方面的问题均作了剖析,并提出了解决问题的建议,可以为气瓶设计和设计文件鉴定工作提供参考。
In this paper the common problems in design of gas cylinder are analyzed and summarized as follows： 1） the contents of design document were imcomplete; 2） both design attribute and appraisal attribute were not defined clearly; 3） the same design with series parameters was lack of standardization; 4） the guarantee value of material strength was not used standardly; 5） the minimum of burst pressure was calculated unscientifically; 6） the maximum of filling weight of cryogenic insulated cylinders was calculated without merit; 7） Valve selection was performed not based on codes and standards; 8） material selection of reinforced layer of fiber-wrapped cylinder was conducted not according to safety technical specifications. The problems mentioned above are analyzed and the corresponding suggestions are given, which could provide references for design of cylinders and document appraisal.
