标准范围
本文件规定了以下方面的设计、型式试验和标记要求:A）？用于安装在可再填充的可运输气瓶上的气瓶阀；b）？成束钢瓶的主阀（不包括球阀）；c）？带集成压力调节器（VIPR）的钢瓶阀或主阀；笔记？1？这包括以下特定的VIPR设计，其中:1)？压力调节系统作为主阀门操作机构（VIPR型？B）。这也包括通过关闭压力调节机构的阀座来实现主阀操作机构的关闭的设计。2)？主阀操作机构位于压力调节系统（VIPR型？C）的低压侧。d）？用于压力桶和管道的阀门；其输送压缩、液化或溶解气体。笔记？2？在不存在歧义的情况下，在本文件中，钢瓶阀、主阀、VIPR以及压力桶和管道用统称为“阀”。本文件不适用于—？低温设备、便携式灭火器和液化石油气（LPG）用阀门；—？快速释放钢瓶阀（例如，用于灭火、防爆和救援应用）-ISO 17871规定了快速释放钢瓶阀的要求，其中包含本文件的规范性参考；—？自闭钢瓶阀和球阀。笔记？3？低温容器阀门的要求在ISO？21011和区域一级，例如在EN？1626.液化石油气阀门的要求在ISO？14245还是ISO？15995.对自-的要求ISO中规定了关闭钢瓶阀？17879.对球阀的要求在ISO？23826.例如，EN？3？系列。本文件仅涵盖阀门作为封闭件的功能。可能集成在阀中的其他功能可以由其他标准涵盖。然而，此类标准不构成根据本文件的要求。注4？除了本文件中给出的那些之外，VIPR的定义和具体要求在ISO？22435用于工业应用或ISO？10524-3用于医疗应用。同样，除了本文件中给出的要求之外，对于带或不带止回功能的余压阀（RPV）的某些具体要求也在ISO？15996.注5？除本文件中给出的要求外，呼吸器用阀门的某些具体要求在地区一级规定，例如在EN？144系列。除本文件中给出的要求外，固定消防系统用快速释放阀的某些具体要求在ISO？16003和在区域一级，例如在EN？12094–4.注6？本文件所涵盖的阀门制造试验和检查要求在ISO？14246.
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.
