标准范围

本文件规定了带集成压力调节器（VIPR）的钢瓶阀门的设计、型式试验方法、标记和说明要求，这些阀门旨在安装在气瓶、压力桶或管道上，或用作输送压缩、液化或溶解气体的钢瓶管束的主阀。这些是对VIPR的要求，是对相关封闭标准（例如ISO？）中给出的要求之外的要求。10297用于钢瓶阀门，ISO？17871用于快速释放钢瓶阀，ISO？17879用于自闭钢瓶阀门或ISO？23826用于球阀。为了ISO？17871，这些要求仅适用于B、C、D和E型快拆钢瓶阀。笔记？1？如果VIPR的压力调节系统充当主要阀门操作机构，则其包含在相关关闭标准中，例如。g.伊索？10297，ISO？17871，ISO？17879和ISO？23826.这也包括通过关闭压力调节系统的阀座来关闭VIPR的主阀操作机构的设计。笔记？2？如果VIPR的主阀操作机构位于压力调节系统的低压侧，则相关关闭标准（例如ISO？10297，ISO？17871，ISO？17879和ISO？23826.笔记？3？在本文件中使用术语“压力容器”以涵盖在气瓶、气瓶束、压力鼓和管之间不需要区分的情况。本文件不适用于以下情况的VIPRA）？医疗应用(参见ISO 10524-3)；b）？液化石油气(LPG)；c）？低温应用。笔记？4？带残余压力装置（RPD）的VIPR的附加要求在ISO？15996.笔记？5？国际/区域法规/标准中可能存在对减压阀的附加要求。

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.
