The invention relates to the technical field of leak detection of buried gas pressure pipelines, in particular to a simple leak detection device for buried gas pressure pipelines. The simple leak detection device comprises an opening device, a conduction unit, a host, and an earphone. The conduction unit comprises a thick-walled stainless steel detection tube, a through hole is integrally formed in the middle part of the thick-walled stainless steel detection tube, and a probe barrel is screwed and fixed at the front end of the thick-walled stainless steel detection tube; and a pickup device is inserted to the inner side of the probe barrel, and a signal output port at the end of the pickup device is connected with a first signal transmission line, which passes through the through hole inthe thick-walled stainless steel detection tube and is connected to a signal input port of the host. Compared with a traditional method of injecting an odorant into compressed air to find leakage points by smell, the device is used to detect leakage points, the detection process is not affected by external factors, the accuracy of leak detection is high, the preparation for leak hunting is not needed, time and effort are saved, and the health of a human body is effective protected.
Description
technical field [0001] The invention relates to the technical field of leakage detection of buried gas pressure pipelines, in particular to a simple leakage detection device for buried gas pressure pipelines. Background technique [0002] At present, during the construction process of the project, the leakage detection method of the buried pipeline is only to inject the odorant into the compressed air in the pipeline, and after the odorant diffuses and flows out from the leakage point with the compressed air, the leakage point is determined by artificial smell (smell smell). The method is single, and the sensitivity of artificial smelling is poor, and the sensitivity of the olfactory nerve is very easy to change due to external factors, and it has a great impact on human health. The diffusion range is large, and the leak point cannot be quickly and accurately found, which brings inconvenience to the leak detection work. [0003] Therefore, we design a simple leak detection ...
