Relief piping pressure drop 帮忙翻译? relief piping pressure drop shall be determined using isothermal compressible gas flow equations. 安全泄压管道的压降(阻力降)通过等温压缩气流的公式来确定。 relief piping pressure drop shall be designed assuming that the back pressure generated after the pressure relief valve opens is a maximum 50% of the set pressure provided that any mechanical limitations of the bellows, bonnet or valve outlet are not exceeded. 安全泄压管道的压降设计时,应假定安全阀开启时产生的背压,最大不超过安全阀的设定压力的50%,假如此压力没有超出波纹管,阀盖,或者阀门出口的任何机械限制条件(意思是说背压不能超出阀组件所能承受的压力,且不超过50%的设定压力)。查看更多
