燃气管网阀门规则配置

研究了燃气管网阀门按照管网故障管段“逐管段隔离原则”，得出“理论配置”模式。管网阀门理论配置定理给出了对管网阀门的理论配置数量与管网结构的关系。按“区域隔离原则’’进行的阀门“规则配置”模式，给出了管网阀门规则配置公式。论述了阀门规则配置实用方法。结合国内燃气管网工程实际，研究了对于一定平均管段长度的管网，阀门密度与规则配置各因素的关系。

Regular Configuration of Valves for Gas Network

＂Theoretical configuration＂ mode of gas network valves according to the principle of ＂isolating section by section＂ of fault section is studied. The theoretical configuration theorem of gas network valves gives the relationship between the theoretical configuration number of gas network valves and network structure. The regular configuration formula of gas network is given according to the regular configuration mode of valves based on the principle of ＂isolating by area＂. The regular configuration method of valves is described. The relationship between valve density and various factors with a certain average length of network sections is studied with domestic engineering practices of gas network.
