| Abstract: | 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. |
