供热、供冷管道需要保温以避免能源浪费是人皆知的事,可是阀门保温却长期以来为人们詹忽略。究其原因大概不外乎:一是人们认为阀门不大,浪费不了多少。二是阀门外形不规则、难包,且修理阀门时拆卸麻烦。三是能量损耗尚未完全与单位乃至个人的经济利益挂起钩。为此,阀门不保温成了习以为常的事了。为了说明阀门保温的必要性与可行性,我们不妨对上述原因大致分析一下。 It is well known that heating and cooling pipes need insulation to avoid energy waste. However, valve insulation has long been ignored by people. The reason is probably nothing more than: First, people think that the valve is not big, not much waste. The second is that the valve is irregular in shape and difficult to pack, and it is troublesome to remove the valve when it is repaired. The third is that the energy loss has not been completely linked to the economic interests of the unit and even the individual. For this reason, it is normal for the valve not to keep warm. In order to explain the necessity and feasibility of valve insulation, we may wish to give a general analysis of the above reasons.
