摘要
基于传热学和弹性力学角度,分析推导某种规格PVC自来水管在一定的低气温环境中体现出来的物理特性,找出这些体现出来的结冻物性与之关联的参数。针对目前普遍存在的水管冻裂堵死现象,进行机理分析,参数化处理,对自来水管结构和材料的改进有重要的指导意义。
This article analysis mainly about the physical characteristics which reflected by some kinds of PVC tap water pipe under the low temperature. And our purpose is to find out the parameters of frozen features associate with it. The article analysis the principle and parameterized processing which direct to the frozen pipes blocked phenomenon prevailing at present. It has important guiding significance for the improvement of the structure and material of tap water pipe.
