摘要： 　分析了液化石油气贮罐在设计过程中, 不同的工作环境真空校核问题。对不同的介质和不同的贮罐内径进行了计算, 找出了处于环境低温下装有丙烯、丙烷混合液化石油气、正丁烷、异丁烷、丁烯、丁二烯的液化石油气贮罐可否按真空校核的规律。对内压与外压筒体壁厚进行了比较, 得出液化石油气的饱和蒸汽压力越大, 按真空校核的概率越小;反之饱和蒸汽压越小, 校核的概率就越大。因此能够在设计中减少不必要的校核, 可以提高设计效率, 缩短产品设计周期。

Abstract:

Vacuum checking problems under the different working environments were analyzed in the design process of liquefied petroleum accumulator pot .With computing different media and inner diameters o f pots , a rule whether a liquefied petroleum pot filled with propylene, propane , butane and butylenes could be checked according to vacuum condition in the low temperature w as found .By comparing thickness of inner -press and outside -press barrel w all, it' s concluded that the larger the saturated stream press of liquefied petroleum gas is, the smaller the probability of vacuum check is.On the contrary , the smaller the saturated stream press of liquefied petroleum gas is, the larger the probability of vacuum checking is.Therefore , the conclusion helps reduce the unnecessary checking , increase the designing efficiency , and shorten the product design period .

Key words: 　Liquefied petroleum gas, Accumulator pot , Vacuum , Shell, Check
