关于电站锅炉安全阀型式试验排放性能测试方法的讨论

Discussion on Discharge Performance Test of Boiler Safety Valve Type Testing

安全阀的排放性能是安全阀产品质量重要考核指标之一,电站锅炉安全阀由于压力高、排量大无法通过实际工况模拟来测试其排放性能,本文通过对拉法尔喷嘴气体稳定流动的质量流量展开分析,说明采用排量系数法评估安全阀排放性能具有很高的可靠性、操作性。

the oischarge performance is one of the important assessment indicators of the safety valve＇s quality. Because of the hi gh pressure and large capacity, discharge performance of boiler safety valve cannot be tested out through actual working conditions simulation. This paper analyses the gas steady flow theory of Rafael nozzle to explain that using dischange coefficient method to assess discharge performance of safety valve is with high reliability and operability.
