防超压安全性保护装置.第9部分:安全装置的应用和安装(不包括单机防爆膜安全装置)

[中文适用范围]： ISO 4126的这一部分涵盖了安全装置的应用和安装，例如安全阀、安全阀和爆破片安全装置的组合、先导式安全阀和用于保护压力设备的受控安全泄压系统。 ISO 4126-6 涵盖了爆破片安全装置的选择、应用和安装。 ISO 4126 的这一部分描述了保护静压设备的安全装置的应用和安装的规范要求。 ISO 4126 本部分中包含的信息假定从安全装置排出的流体为单相流。 ISO 4126-10 提供了针对两相流条件的指南。 通过足够容量的管道连接在一起的系统中的设备，没有潜在的堵塞，并且不包含任何可以隔离任何部件的阀门，可以被认为是泄压应用的安全系统。 ISO 4126的这一部分不涉及其他安全装置，例如安全相关的监测、控制和调节装置以及一些国家法规允许的其他限制装置。 [外文原描述]： ISO 4126-9:2008 covers the application and installations of safety devices such as safety valves, safety valves and bursting disc safety devices in combination, pilot-operated safety valves and controlled safety pressure-relief systems for the protection of pressure equipment. ISO 4126-6 covers the selection, application and installation of bursting disc safety devices. ISO 4126-9:2008 describes the normative requirements for applications and installations of safety devices to protect static pressure equipment. The information contained in ISO 4126-9:2008 assumes single-phase flow of the fluid discharged from the safety device. ISO 4126-10 provides guidance specific to two-phase flow conditions. Equipment connected together in a system by piping of adequate capacity, which is free from potential blockages and does not contain any valve that can isolate any part, can be considered to be a safety system for the application of pressure relief. ISO 4126-9:2008 does not deal with other safety devices, such as safety related monitoring, control and regulation devices and other limiting devices allowed by some national regulations.
