供水主干管突发渗漏事故中阀门抢修流程的优化研究OA

The operating status of valves in water supply networks directly affects the emergency repair efficiency of sudden leakage accidents.Taking a sudden leakage accident of a main water supply pipe as a case study,the corre-lation between valve status and water pressure fluctuations are explored and a full-process disposal framework of"leak point analysis-difficulty analysis-process analysis-review and optimization"is constructd.By designing a three-level progressive valve closing scheme and combining the real-time monitoring data of the dispatching system and smart fire hydrants,the emergency repair process is precise controlled.The study shows that the daily inspection and maintenance quality of valves and operational standardization are key factors restricting emergency repair effi-ciency.The dynamic adaptability of the hierarchical progressive valve closing scheme and the collaborative applica-tion of information-based tools can significantly shorten recovery time of the water supply.This study clarifies the influence path of valve status on the emergency repair process,provides an operable technical paradigm for the dis-posal of sudden accidents in main water supply pipes,and has practical significance for improving the emergency resilience of water supply pipe networks.
