摘　　要：蒸汽阀门的保温是工业热力系统保温过程中经常忽略的细节,本文主要通过热力学量化计算的方式分析一只蒸汽阀门(横置)在不做任何保温处理的情况下损失的热能,从而更直观地反映出日常生产运行过程中经常忽略的节能细节,希望能引起一定的重视。The insulation of steam valve is a detail often ignored in the insulation process of industrial thermal system.This paper mainly analyzes how much heat energy a steam valve(horizontal)will lose without any insulation treatment by means of thermodynamic quantitative calculation.So as to more intuitively reflect some energy-saving details often ignored in the process of daily production and operation,so that we can attract some attention.
