大型蒸汽管网系统放空阀、安全阀的设计选型

摘要

Taking a system design for steam piping network in a large-sized chemical project as a actual example, author has mainly introduced the se- lection gist, selection principle for venting quantity of vent valve and capacity of safety valve as well as the determination mode for set pressure values of vent valve and safety valve in case of type selection of design.%以某大型化工项目蒸汽管网系统的设计为实例，重点介绍了设计选型时对放空阀放空量和安全阀容量的选择要领、选取原则以及放空阀、安全阀开启压力值的确定方式。
