气瓶 带集成压力调节器的气瓶阀 规范和型式试验

[中文适用范围]： 本文件规定了用于安装在气瓶、压力桶或管道上或用作输送压缩、液化或溶解气体的气瓶束的主阀的带集成压力调节器的气瓶阀门 (VIPR) 的设计、型式试验方法、标记和说明要求。这些要求是对 VIPR 的要求的补充，这些要求是相关封闭标准中给出的要求的补充，例如 ISO 10297 中关于气瓶阀门的要求、ISO 17871 中关于快速释放气瓶阀门的要求、ISO 17879 中关于自闭式气瓶阀门的要求或 ISO 23826 中关于球阀的要求。对于 ISO 17871，这些要求仅适用于 B、C、D 和 E 型快放气瓶阀门。 注 1：如果 VIPR 的压力调节系统用作主阀门操作机构，则其受相关封闭标准的约束，例如 ISO 10297、ISO 17871、ISO 17879 和 ISO 23826。这还包括通过关闭压力调节系统的阀座来关闭 VIPR 主阀门操作机构的设计。 注 2：如果 VIPR 的主阀门操作机构位于压力调节系统的低压侧，则其受相关封闭标准的约束，例如 ISO 10297、ISO 17871、ISO 17879 和 ISO 23826。 注 3：本文件中使用的术语“压力容器”涵盖无需区分气瓶、气瓶束、压力桶和管道的情况。本文件不适用于以下 VIPR：a) 医疗应用（见 ISO 10524-3）；c) 低温应用。b) 液化石油气 (LPG)；注 4：带残压装置 (RPD) 的 VIPR 的附加要求在 ISO 15996 中规定。注 5：国际/地区法规/标准中可能存在对压力释放阀的附加要求。 [外文原描述]： This document specifies design, type test methods, marking and instruction requirements for cylinder valves with integrated pressure regulators (VIPRs) intended to be fitted to gas cylinders, pressure drums or tubes or used as a main valve for bundles of cylinders that convey compressed, liquefied or dissolved gases. These are requirements for VIPRs that are in addition to those given in the relevant closure standard, for example, in ISO 10297 for cylinder valves, in ISO 17871 for quick-release cylinder valves, in ISO 17879 for self-closing cylinder valves or in ISO 23826 for ball valves. For ISO 17871, these requirements are only applicable to quick-release cylinder valves types B, C, D and E. NOTE 1 If the pressure regulating system of a VIPR is acting as the primary valve operating mechanism, it is covered by the relevant closure standard, e.g. ISO 10297, ISO 17871, ISO 17879 and ISO 23826. This also includes designs where closure of the primary valve operating mechanism of a VIPR is obtained by closing the seat of the pressure regulating system. NOTE 2 If the primary valve operating mechanism of a VIPR is located at the low-pressure side of the pressure regulating system, it is covered by the relevant closure standard, e.g. ISO 10297, ISO 17871, ISO 17879 and ISO 23826. NOTE 3 The term “pressure receptacle” is used within this document to cover instances where no differentiation is necessary between gas cylinders, bundles of cylinders, pressure drums and tubes. This document does not apply to VIPRs for a) medical applications (see ISO 10524-3); b) liquefied petroleum gas (LPG); c) cryogenic applications. NOTE 4 Additional requirements for a VIPR with a residual pressure device (RPD) are specified in ISO 15996. NOTE 5 Additional requirements for pressure relief valves can exist in international/regional regulations/ standards.
