Description
本发明涉及市政供水领域，特别是涉及一种基于减压阀的供水管网压力管理系统性能测试装置及方法。The invention relates to the field of municipal water supply, in particular to a performance testing device and method for a water supply pipe network pressure management system based on a pressure reducing valve.
随着城镇人口的快速增减，城市建设的高速发展，水资源日益紧缺，供水成本不断提高，然而供水管网漏损致使水资源的大量浪费，供水行业经济损失巨大。供水管网漏损是指由于管体、附配件和接口等管道部件破裂或调节构筑物漏水等原因导致供水管路中的水在传输的过程中，有一部分水流出管道，造成水浪费的现象。有效控制管网漏损率情况，切实保障城市供水效率已成为供水行业至关重要的任务。压力管理是解决城市供水管网压力分布不均、漏损严重等热点问题的重要方法之一。通过压力管理的手段，使区域供水服务压力平衡，实现智能精细化管理，为供水管网优化运行带来综合效益。压力控制具有平衡管网压力、优化管网运行、减少漏水事故、提高用水舒适度，节约水资源等优点。供水管网管理也是一个长期的运维过程，通过压力的优化运行可以延长供水管网的使用寿命，提高管网资产使用的经济性。With the rapid increase and decrease of urban population and the rapid development of urban construction, water resources are increasingly scarce, and the cost of water supply continues to increase. However, the leakage of water supply pipe network leads to a large amount of waste of water resources, and the economic loss of the water supply industry is huge. Leakage of the water supply pipe network refers to the phenomenon that part of the water in the water supply pipe flows out of the pipe during the transmission process due to the rupture of the pipe body, accessories, interfaces and other pipe parts or the leakage of the adjustment structure, resulting in water waste. Effectively controlling the leakage rate of the pipe network and effectively ensuring the efficiency of urban water supply has become a crucial task for the water supply industry. Pressure management is one of the important methods to solve hot issues such as uneven pressure distribution and serious leakage in urban water supply network. Through the means of pressure management, the regional water supply service pressure is balanced, intelligent and refined management is realized, and comprehensive benefits are brought to the optimized operation of the water supply network. Pressure control has the advantages of balancing pipe network pressure, optimizing pipe network operation, reducing water leakage accidents, improving water comfort, and saving water resources. Water supply network management is also a long-term operation and maintenance process. The service life of the water supply network can be extended through the optimized operation of the pressure, and the economic efficiency of the use of pipeline network assets can be improved.
