Problems solved by technology

However, this method is often taken only when there is a water leak, and it is usually not carried out frequently. Even if the leak is heard, there is no great confidence, especially because the pipeline from the water plant is very long, buried deep, and the terrain is complicated. , the leakage problem cannot be solved only by listening to leaks

Abstract

This invention relates to a method for testing leakage of supplying pipelines of non-conduction materials, which sets many connected electrodes in walls of pipelines of different regions of non-conducting materials buried away from ordinary metal pipelines as one pole of conduction and sets many electrodes to be connected one by one outside of the pipeline walls of different regions as the other pole, thus, ordinarily, leakage does not happen and the resistance between electrodes inside and outside of the pipe is large, the device does not alarm at the time, when leakage happens, water infiltrates into the earth and resistance of the electrodes buried in the earth reduces greatly and the device alarms because of small resistance.

Description

technical field [0001] A leak detection method for a water supply pipeline, in particular a leak detection method for a water supply pipeline made of non-conductive material. Background technique [0002] For the leak detection method of non-conductive material water supply pipelines, the current solution is the same as that of ordinary metal pipelines. Usually, the leak detection method is used. When the people are quiet at night, the leak detection device is used, and the probe is closely attached to the ground closest to the pipeline. The weak sound wave of water leakage is amplified, and then transmitted to the earpiece, so that people can get the message of water leakage. However, this method is often taken only when there is a water leak, and it is usually not carried out frequently. Even if the leak is heard, there is no great confidence, especially because the pipeline from the water plant is very long, buried deep, and the terrain is complicated. However, the leaki...
