标准摘要
[中文适用范围]： 本文件规定了装有余压装置的气瓶阀门（以下简称余压阀门（RPV））的设计、型式试验和标记要求。本文件适用于以下类型的 RPV：a) 用于安装在可再充装可运输气瓶上的气瓶阀门；b) 气瓶组的主阀（不包括球阀）；c) 带有集成压力调节器（VIPR）的气瓶阀门或主阀；d) 用于输送压缩或液化气体的压力桶和管道的阀门。注：若无歧义，本文件中将气瓶、压力桶、管道和气瓶组统称为“气瓶”。这些要求是对 ISO 10297 要求的补充。本文件也适用于 RPD 独立设备。本文件不适用于便携式灭火器、低温设备、低压制冷剂气体（气瓶试验压力低于 50 bar）、溶解气体或液化石油气（LPG）的 RPV。 [外文原描述]： ISO 15996:2017 specifies design, type testing and marking requirements for cylinder valves incorporating residual pressure devices, hereinafter referred to as residual pressure valves (RPVs). This document applies to the following types of RPVs: a) cylinder valves intended to be fitted to refillable transportable gas cylinders; b) main valves (excluding ball valves) for cylinder bundles; c) cylinder valves or main valves with integrated pressure regulator (VIPR); d) valves for pressure drums and tubes; which convey compressed or liquefied gases. NOTE Where there is no risk of ambiguity, cylinders, pressure drums, tubes and cylinder bundles are addressed with the collective term "cylinder" within this document. These requirements are in addition to those in ISO 10297. For RPD stand-alone devices this document can also be applied. ISO 15996:2017 does not apply to RPVs for portable fire extinguishers, cryogenic equipment, low pressure refrigerant gases (cylinder test pressure less than 50 bar), dissolved gases or liquefied petroleum gas (LPG).
