安全阀泄放量计算简析

Analysis of Calculating Relief Capacity of Safety Valve

安全阀系压力容器在运行中实现超压泄放的安全附件之一,泄放量对安全阀尺寸的计算与选型起着至关重要的作用,但API标准与国家标准对安全阀在火灾工况时的计算方法却不一样,因此对在国内做国外项目时提出了新的要求。

Safety valve is one of safety devices performing pressure relief when overpressure exists in pressure vessel. Relief capability play significant role in selection of valve type and determination of valve size. There are differences between API standard and Chinese Standard, thus some new requirements have been presented for oversea projects.
