气瓶阀门保护帽和防护罩设计、结构和试验

[中文适用范围]： 本文件规定了液化、溶解或压缩气体气瓶上使用的阀门保护帽和阀门护罩的要求。 阀门保护帽和阀门护罩是可用于保护气瓶阀门的一些选件，包括运输过程中带有集成压力调节器 (VIPR) 的阀门。 本文件适用于阀门保护帽和阀门护罩，它们本质上为气瓶阀门提供主要保护。 它还可以用于测试连接到气瓶包装上的其他设备（例如，处理装置），即使在气瓶阀门本身能够承受损坏而不释放内容物的情况下也是如此。 本文件不包括用于水容量为 5 升或以下的钢瓶的保护装置，以及保护装置通过焊接或钎焊到钢瓶上的凸耳固定的钢瓶，或者直接焊接或铜焊到钢瓶上的钢瓶。 本文件不涵盖呼吸器气瓶的阀门保护。 注：小型气瓶（例如医用气瓶）通常采用外包装（例如托盘）运输，以满足运输法规。 本文件没有规定使阀门保护装置能够用于提升气缸所必需的要求。 [外文原描述]： This document specifies the requirements for valve protection caps and valve guards used on cylinders for liquefied, dissolved or compressed gases. Valve protection caps and valve guards are some of the options available to protect cylinder valves, including valves with integral pressure regulators (VIPRs) during transport. This document is applicable to valve protection caps and valve guards which inherently provide the primary protection of a cylinder valve. It can also be used to test other equipment (e.g., handling devices) attached to cylinder packages, even in cases where the cylinder valve is inherently able to withstand damage without release of the content. This document excludes protection devices for cylinders with a water capacity of 5 l or less and cylinders whereby the protection device is fixed by means of lugs welded or brazed to the cylinder, or is welded or brazed directly to the cylinder. This document does not cover valve protection for breathing apparatus cylinders. NOTE Small cylinders (e.g., medical cylinders) are commonly transported in an outer-packaging (e.g., pallet) to meet transport regulations. This document does not specify requirements that could be necessary to enable the valve protection device to be used for lifting the cylinder.
