Water leakage heat absorption type pipeline leak detecting method

Abstract

The invention relates to a leakage detection method for leakage water endothermic type pipelines, comprising power lines arranged in the direction of pipelines, controlled heat source lines, pulse lines and back transmission buses for signals. A heat source body is parallelly arranged on a controlled heat source line at an interval of distance with each heat source body is closely attached to a temperature transmitter and a encoding detection device. leakage water makes the temperature of the vicinity land drop, simultaneously taking away part heat of the heating heat source body, as a result, the time for the temperature transmitter in the section reaching the temperature threshold is longer than that under conditions without water leakage, the water leaking section can be identified by a smart identification recorder through identifying the two different heating-up times mentioned above.

Description

technical field [0001] A leak detection method for pipelines, in particular to a leakage detection method for water-absorbing heat-absorbing pipelines. Background technique [0002] Leakage of water supply pipes is a common occurrence, especially where the leak is located. The current solution is generally to use the leak listening method. When people are quiet at night, use a leak listener, and stick the probe close to the nearest pipe. On the ground, 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 after knowing that there is a water leak, and it is generally not carried out frequently. When the leak is heard, the loss of the leak is often very serious, and even if the leak is heard, there is no great certainty, especially after coming out of the water plant. The pipes in the country are very long, buried very deep, and the ground condition...

However, this method is often taken only when there is a leak, and it is usually not carried out frequently. When the leak is heard, the loss of the leak is often very serious, and even if the leak is not very sure, especially after coming out of the water plant The pipeline is very long, buried deep, and the ground conditions are complicated. The leakage problem cannot be solved only by listening to the leakage method. The current leakage rate is as high as 15%, which shows this problem.
