超压泄放设计中的安全阀排量系数探讨
摘要
Abstract
Understanding the displacement coefficient of the safety valve and clarifying its value are the key to the overpressure relief design of the safety valve.Existing standards and specifications have different definitions and values of displacement coefficients.Based on this,this paper investigates domestic and foreign standards and specifications including GB/T 150.1-2024,GB/T 12241-2021,GB/T 12242-2021,GB/T 12243-2021,GB/T 28778-2023,SH/T 3210-2020,API 520-2020,ASME BPVC VIII-2023,ISO 4126-1:2013 et al.analyzed the similarities and differences of relevant terms,names,definitions and value regulations for displacement coefficients,discussed the values and influencing factors of rated displacement coefficients based on literature information,and clarified the use of displacement coefficients in overpressure design.The work in this paper has guiding significance for the overpressure relief design of safety valves.关键词
