标准摘要
[中文适用范围]： 本文件规定了低温应用泄压阀的设计、制造和测试要求，即除了在环境温度到低温的环境温度下运行外，还需要在低于-10°C的低温流体下运行。 本文件适用于尺寸不超过 DN 150 的阀门，设计用于排放单相蒸汽或气体。 可以对阀门进行指定、构造和测试，使其适合与多种气体或气体混合物一起使用。 注：本文件不提供确定特定低温容器安全阀容量的方法。 ISO 21013-3 中提供了此类方法。 [外文原描述]： This document specifies the requirements for the design, manufacture and testing of pressure relief valves for cryogenic service, i.e. for operation with cryogenic fluids below −10 °C in addition to operation at ambient temperatures from ambient to cryogenic. This document is applicable to valves not exceeding a size of DN 150 designed to relieve single-phase vapours or gases. A valve can be specified, constructed and tested such that it is suitable for use with more than one gas or with mixtures of gases. NOTE This document does not provide methods for determining the capacity of relief valve(s) for a particular cryogenic vessel. Such methods are provided in ISO 21013-3.
