21、N与LB换算我们通常所用的PNCLass都是压力的一种表示方法所不同的是它们所代表承受的压力对应参照温度不同PN欧洲体系是指在120C下所对应的压力而CLass美标是指在425.5C下所对应的压力。所以在工程互换中不能只单纯的进行压力换算如CLass300#单纯用压力换算应是2.1MPa但如果考虑到使用温度的话它所对应的压力就升高了根据材料的温度耐压试验测定相当于5.0MPa。阀门的体系有2种一种是德国包括我国为代表的以常温下我国是100度、德国是120度的许用工作压力为基准的“公称压力”体系。一种是美国为代表的以某个温度下的许用工作压力为代表的“温度压力体系”美国的温度压力体系中除150LB

22、以260度为基准外其他各级均以454度为基准。150磅级150psi=1MPa的25号碳钢阀门在260度时候许用应力为IMPa而在常温下的许用应力要比IMPa大得多大约是2.0MPa。所以一般说美标150LB对应的公称压力等级为2.0MPa300LB对应的公称压力等级为5.0MPa等等。因此不能随便按照压力变换公式来变换公称压力和温压等级。PN是一个用数字表示的与压力有关的代号是提供参考用的一个方便的圆整数PN是近似于折合常温的耐压MPa数是国内阀门通常所使用的公称压力。对碳钢阀体的控制阀指在200C以下应用时允许的最大工作压力对铸铁阀体指在120C以下应用时允许的最大工作压力对不锈钢阀体的控制阀指在250C以下应用时大工作压力。当工作温度升高时阀体的耐压会降低美标阀门以磅级来表示公称压力磅级是对于某一种金属的结合温度和压力的计算结果他根据ANSIB16.34的标准来计算。磅级与公称压力不是一一对应的主要原因是磅级与公称压力的温度基准不同。我们通常使用软件来计算但是也要懂得使用表格来查磅级。日本主要用K值表示压力等级。对于气体的压力在中国我们一般
