标准摘要
[中文适用范围]： 本文件规定了安装在输送压缩、液化或溶解气体的可再充装移动气瓶上的自闭气瓶阀的设计、型式试验、标记和制造试验以及检验要求。 注 1：这种自闭式气瓶阀的主要应用是校准气体和饮料行业。 本文件涵盖了自闭式钢瓶阀作为关闭装置的功能。 注 2：标准钢瓶阀的要求在 ISO 10297 中给出。 快速释放钢瓶阀的要求在 ISO 17871 中给出。 本文件不适用于低温设备、便携式灭火器或液化石油气的自闭式钢瓶阀。 天然气（液化石油气）。 注3：低温容器阀门的要求在ISO 21011和地区层面（例如EN 1626）中规定。 在地区层面对便携式灭火器阀门的要求在地区层面（例如EN 3系列）规定。 ISO 14245 中规定了自闭式液化石油气钢瓶阀的要求。 注 4：国际/地区法规/标准中可能规定了泄压装置的附加要求。 [外文原描述]： ISO 17879:2017 specifies the design, type testing, marking and manufacturing tests and examinations requirements for self-closing cylinder valves intended to be fitted to refillable transportable gas cylinders which convey compressed, liquefied or dissolved gases. NOTE 1 The main applications for such self-closing cylinder valves are in the calibration gas and beverage industries. ISO 17879:2017 covers the function of a self-closing cylinder valve as a closure. NOTE 2 Requirements for standard cylinder valves are given in ISO 10297. Requirements for quick-release cylinder valves are given in ISO 17871. ISO 17879:2017 is not applicable to self-closing cylinder valves for cryogenic equipment, for portable fire extinguishers, or for liquefied petroleum gas (LPG). NOTE 3 Requirements for valves for cryogenic vessels are specified in ISO 21011 and at a regional level, for example, in EN 1626. Requirements for valves for portable fire extinguishers at a regional level are specified, for example, in EN 3 series. Requirements for self-closing LPG cylinder valves are specified in ISO 14245. NOTE 4 Additional requirements for pressure-relief devices might be specified in international/regional regulations/standards.
