This International Standard specifies design, type testing and marking requirements for: a) cylinder valves intended to be fitted to refillable transportable gas cylinders; c) cylinder valves or main valves with integrated pressure regulator (VIPR); b) main valves (excluding ball valves) for cylinder bundles; which convey compressed, liquefied or dissolved gases. NOTE 1 Where there is no risk of ambiguity, cylinder valves, main valves and VIPR are addressed with the collective term “valves” within this International Standard. This International Standard covers the function of a valve as a closure. This International Standard does not apply to — valves for cryogenic equipment, portable fire extinguishers and liquefied petroleum gas (LPG), and — quick-release valves (e.g. for fire-extinguishing, explosion protection and rescue applications), nonreturn valves or ball valves. NOTE 2 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 quick-release valves are specified e.g. in ISO 17871. Requirements for valves for portable fire extinguishers at a regional level are specified e.g. in EN 3 series. Requirements for non-return valves and ball valves might be specified in international/regional standards. NOTE 3 Requirements for manufacturing tests and examinations of valves covered by this International Standard are given in ISO 14246. NOTE 4 Additional requirements for VIPR are specified in ISO 22435 for industrial applications or ISO 10524-3 for medical applications. Additional requirements for residual pressure valves with or without a non-return function are specified in ISO 15996. Additional requirements for pressure-relief devices might be specified in international/regional regulations/standards. NOTE 5 Additional specific requirements for valves for breathing apparatus at a regional level are specified e.g. in EN 144 series. Additional specific requirements for quick-release valves for fixed fire-fighting systems are specified in ISO 16003 and at a regional level e.g. in EN 12094–4.
中心具有气瓶、气瓶阀门(限天然气瓶阀)、蓄能器和简单压力容器4项型式试验资质;能够对钢质无缝气瓶、钢质焊接气瓶、溶解乙炔气瓶、车用纤维增强复合材料气瓶、汽车用压缩天然气钢瓶、汽车用液化天然气气瓶等16种气瓶产品进行全项目的检验和试验;能够依据ISO国际标准以及美国DOT标准、欧盟等国外先进标准对气瓶进行各项试验,每年接受国内制造厂商的出口委托试验近200项。...
鉴于液相瓶风险较大,只规定了50kg一种规格;二是完善气瓶钢印信息。钢印信息必须包括制造商、允许充装量、制造年月和设计使用年限等重要信息,并要求印制深度不得低于0.7mm,便于使用者日常识读和满足监管要求;三是增加电子识读标志。电子识读标志写入了气瓶的关键信息,包括产品信息、合格证、质量证明书、型式试验证书等。消费者可以通过扫描电子识读标志判别气瓶真伪;四是统一气瓶瓶身颜色。...
6.供给阀的动作是否灵活,是否缺件,它和中压导管的连接是否牢固,是否损坏。 供给阀和呼气阀是否匹配。带上呼气器,打开气瓶开关,按压供给阀杠杆使其处于工作状态。在吸气时,供给阀应供气,有明显的"咝咝"响声。 在呼气或屏气时,供给阀停止供气,没有"咝咝"响声,说明匹配良好。 ...
