摘　　要：提出一种区别于广度优先搜索遍历算法的关阀策略。根据管道流体的流体力学性质,利用计算机管网仿真技术,采用基于网络元思想的水力计算方法,通过计算节点处的压力来判断需要关闭的阀门。将该方法与传统遍历算法进行对比发现,该方法计算效率提高了38.8%。提出的关阀策略在某市中压燃气管网的工程实践中得到有效应用。A valve closing strategy different from breadth-first search traversal algorithm is proposed. According to the hydromechanical properties of pipeline fluid, the computer pipe network simulation technology and the hydraulic calculation method based on the network element idea are used to determine the valve to be closed by calculating the pressure at the node. After comparing this method with the traditional traversal algorithm, it is found that the computational efficiency of this method is increased by 38.8%. The proposed valve closing strategy has been effectively applied in the engineering practice of a city′s medium-pressure gas pipeline network.
