标准范围

ISO 4126-3:2006规定了由符合ISO 4126-1、ISO 4126-4和ISO 4126-5的安全阀或CSPR（受控安全泄压系统）以及符合ISO 4126-2的爆破片安全装置（安装在距离阀门入口不超过五个管道直径的范围内）串联组合而成的产品的要求。它规定了此类产品的设计、应用和标记要求，这些产品用于保护压力容器、管道或其他外壳免受过度压力的影响，包括爆破片安全装置、安全阀或CSPR，以及短长度的连接管或短管（如适用）。此外，还给出了确定施胶组合中使用的组合流量系数的方法。

ISO 4126-3:2006 specifies the requirements for a product assembled from the in-series combination of safety valves or CSPRS (controlled safety pressure relief systems) according to ISO 4126-1, ISO 4126-4 and ISO 4126-5, and bursting disc safety devices according to ISO 4126-2 installed within no more than five pipe diameters from the valve inlet. It specifies the design, application and marking requirements for such products, which are used to protect pressure vessels, piping or other enclosures from excessive pressure, and which comprise the bursting disc safety device, a safety valve or CSPRS and, where applicable, a short length of connecting pipe or spool piece. In addition, it gives a method for establishing the combination discharge factor used in sizing combinations.
