燃气管道管径选取方法的探讨

摘要

城市燃气管道输配系统流量的计算关系到管网系统的经济性和可靠性，文章以宝鸡市金利苑9号楼为例，分别采用同时工作系数法与采暖热指标法计算燃气用具耗气量，分析不同计算方法对燃气低压架空管道管径选取的影响。%The flow calculation in city gas pipeline transmission and distribution system is related to the economy and reliability of the network system. Taking some building as an example and using the simultaneously coefficient method and heating index method separately to calculate the gas consumption of appliances, the paper analyzes the effects on selecting the low-pressure overhead pipeline diameter by using different calculation methods.
