标准摘要
[中文适用范围]: 本文件规定了下列设备的设计、型式试验和标记要求:a) 用于可再充装可运输气瓶的气瓶阀门;b) 气瓶组的主阀(不包括球阀);c) 带有集成压力调节器的气瓶阀门或主阀(VIPR);注 1 包括以下特定的 VIPR 设计:1) 压力调节系统充当主阀门操作机构(VIPR B 型)。这还包括通过关闭压力调节机构阀座来关闭主阀门操作机构的设计。2) 主阀门操作机构位于压力调节系统的低压侧(VIPR C 型)。d) 压力桶和压力管阀门;用于输送压缩、液化或溶解气体。注 2 为避免歧义,本文件中将气瓶阀门、主阀、VIPR 和压力桶和压力管阀门统称为“阀门”。本文件不适用于 — 低温设备、便携式灭火器和液化石油气 (LPG) 的阀门; — 快速释放式气瓶阀门(例如用于灭火、防爆和救援应用)- 快速释放式气瓶阀门的要求在 ISO 17871 中规定,该标准包含对本文件的规范性引用; — 自闭式气瓶阀门和球阀。 注 3:低温容器阀门的要求在 ISO 21011 和区域层面(例如 EN 1626)中规定。LPG 阀门的要求在 ISO 14245 或 ISO 15995 中规定。自闭式气瓶阀门的要求在 ISO 17879 中规定。球阀的要求在 ISO 23826 中规定。例如,EN 3 系列规定了便携式灭火器阀门的区域层面要求。本文件仅涵盖阀门作为闭合装置的功能。阀门中可能集成的其他功能可以由其他标准涵盖。但是,这些标准并不构成本文件的要求。注 4 除了本文件给出的要求外,工业应用的 ISO 22435 或医疗应用的 ISO 10524-3 还规定了 VIPR 的定义和具体要求。同样,除了本文件给出的要求外,ISO 15996 还规定了带或不带止回功能的余压阀 (RPV) 的某些具体要求。注 5 除了本文件给出的要求外,呼吸设备阀门的某些具体要求在区域层面规定,例如 EN 144 系列。除了本文件给出的要求外,固定消防系统快速释放阀的某些具体要求在注 6 中规定了本文件涵盖的阀门制造测试和检查要求在 1 中给出 [外文原描述]: This document specifies design, type testing and marking requirements for: a) cylinder valves intended to be fitted to refillable transportable gas cylinders; b) main valves (excluding ball valves) for bundles of cylinders; c) cylinder valves or main valves with integrated pressure regulator (VIPR); NOTE 1 This includes the following specific VIPR designs where: 1) The pressure regulating system is acting as the primary valve operating mechanism (VIPR type B). This also includes designs where closure of the primary valve operating mechanism is obtained by closing the seat of the pressure regulating mechanism. 2) The primary valve operating mechanism is located at the low-pressure side of the pressure regulating system (VIPR type C). d) valves for pressure drums and tubes; which convey compressed, liquefied or dissolved gases. NOTE 2 Where there is no risk of ambiguity, cylinder valves, main valves, VIPRs and valves for pressure drums and tubes are addressed with the collective term “valves” within this document. This document does not apply to — valves for cryogenic equipment, portable fire extinguishers and liquefied petroleum gas (LPG); — quick-release cylinder valves (e.g. for fire-extinguishing, explosion protection and rescue applications) - requirements for quick-release cylinder valves are specified in ISO 17871 which contains normative references to this document; — self-closing cylinder valves and ball valves. NOTE 3 Requirements for valves for cryogenic vessels are specified in ISO 21011 and at a regional level, e.g. in EN 1626. Requirements for LPG valves are specified in ISO 14245 or ISO 15995. Requirements for self-closing cylinder valves are specified in ISO 17879. Requirements for ball valves are specified in ISO 23826. Requirements for valves for portable fire extinguishers at a regional level are specified, for example, in the EN 3 series. This document only covers the function of a valve as a closure. Other functions that are possibly integrated in the valve can be covered by other standards. Such standards do however not constitute requirements according to this document. NOTE 4 Definition of and specific requirements for VIPRs in addition to those that are given in this document are specified in ISO 22435 for industrial applications or ISO 10524-3 for medical applications. Similarly, certain specific requirements for residual pressure valves (RPV) with or without a non-return function in addition to those that are given in this document are given in ISO 15996. NOTE 5 Certain specific requirements for valves for breathing apparatus in addition to those that are given in this document are specified at a regional level, for example, in the EN 144 series. Certain specific requirements for quick-release valves for fixed fire-fighting systems in addition to those that are given in this document are specified in ISO 16003 and at a regional level, for example, in EN 12094–4. NOTE 6 Requirements for manufacturing tests and examinations of valves covered by this document are given in ISO 14246.
