Abstract

The invention provides a method for detecting downstream pipe network leakage by monitoring the pressure state of a pressure adjusting device. According to the method, pressure collecting devices arearranged on the upstream and the downstream of the pressure adjusting device to monitor the pressure state of the pressure adjusting device, flow of a downstream pipe network is further monitored, tiny leakage monitoring and leakage amount calculating can be achieved through the state of the pressure adjusting device and the flow change, and the method solves the technical problems that an existing method for monitoring downstream leakage of a fuel gas pipe network is low in monitoring frequency, poor in reliability and high in labor cost. The method can be widely applied to monitoring of leakage of the low-pressure pipe network.

Description

technical field [0001] The invention relates to the technical field of leakage monitoring, in particular to a method for realizing leakage detection of a downstream pipe network by monitoring the pressure state of a pressure regulating device. Background technique [0002] Natural gas is one of the most important clean energy sources for human beings. With the increase of proven reserves and the improvement of mining technology, the use of natural gas is becoming more and more popular. Natural gas is flammable and explosive, and it is also a greenhouse gas. Therefore, establishing a real-time leakage monitoring system and leakage early warning mechanism is not only of great safety significance, but also an urgent need for environmental protection. [0003] At present, the leakage monitoring of the downstream gas pipeline network mainly adopts the method of manual inspection. For the downstream low-pressure pipeline network with many branch pipelines, it takes a lot of manpow...
