液化石油气贮罐需要安装安全放散装置,通常都采用安全阀。安全阀是一种定型产品,在液化石油气工程设计中需针对贮罐条件进行安全阀型号的选择。选用的主要计算原则是要保证贮罐在外部火灾情况下具有足够的安全放散能力以保护贮罐不致发生超压而破坏。安全阀计算的公式有各种。本文将通过对几种安全阀选用计算公式的分析,对安全阀选用公式进行比较;并提出推荐选用计算公式。 Liquefied petroleum gas tanks need to be fitted with safety release devices, which are usually safety valves. The safety valve is a styling product. In the LPG engineering design, the safety valve model should be selected according to the conditions of the tank. The main calculation principle chosen is to ensure that the tank has sufficient safety divergence in case of external fire to protect the tank from overpressure and damage. There are various formulas for calculating the safety valve. This article will use several calculation formulas to analyze the safety valve, compare the safety valve selection formula, and recommend the use of calculation formula.
