摘 要
球罐作为大容量、有压贮存容器，在各工业部门中作为液化石油气、液化天然气、液氧、液氮、液氢、液氨、及其他中间介质的贮存；也作为压缩空气、压缩气体的贮存。在原子能工业中球罐还作为安全壳使用。本课题是2000m3低温球罐设计，通过查阅相关书籍，对该球罐的结构、强度进行详细的计算，从附件、可能引起的突发因素等多角度考虑，以GB12337-2011《钢制球形储罐》，GB150-2011《钢制压力容器》，GB50094-2011《球形储罐施工及验收规范》作为设计、制造、检验和验收的规范标准对该球罐进行了设计，最终完成了本课题设计。

Abstract
Spherical tank used as a large capacity, pressure container, in the industrial sector as liquefied petroleum gas, liquefied natural gas, liquid oxygen, liquid nitrogen, liquid hydrogen, liquid ammonia, and other medium storage; also as compressed air, compressed gas storage. In the atomic energy industry in spherical tank also as safety shell. This topic is the 2000m low temperature spherical tank design, through consulting relevant books, on the spherical tank structure, intensity of the detailed calculation, from attachment, may cause unexpected factors and other point of view, to GB12337-2011\steel spherical tanks\GB150-2011\steel pressure vessel\GB50094-2011\code for construction and acceptance of spherical storage tank\as the design, manufacture, inspection and acceptance standard of the spherical tank is designed, the final completion of the project design. Through this design, I understand
Key words: design, calculation, spherical tank
