Abstract

The invention provides a leakage detection equipment which is equipped with a detection pipeline for detecting leakage of pipeline where liquid flows through and determines whether the liquid leaks from the pipeline based on voltage change of the detection pipeline. The leakage detection equipment is provided, which detects whether the detection pipeline comprising a plurality of leads leaks. The leakage detection equipment comprises the detection pipeline comprising a first to a third wire, wherein end ports of the first to third wires are connected electrically via a diode; a pipeline measuring unit for measuring a pipeline voltage in a special position point of each of the second and third wires after applying constant current to the first wire; and a microcomputer for detecting whether the pipeline leaks based on the pipeline voltage of each of the second and third wires.

Description

technical field [0001] The present invention relates to a leakage detecting apparatus, and more particularly, to a detection pipeline installed for detecting a leak on a pipe through which a liquid flows and to determine whether the liquid is Leak detection equipment for leaks from pipes. Background technique [0002] Since pipelines such as water pipelines or oil pipelines are generally buried under the ground, when liquid leaks from the pipeline due to damage to the pipeline or its aging, the leakage of the pipeline is not detected at an early stage, but Detecting the leakage of liquid after it has occurred requires a lot of time and expense. To deal with these problems, a conventional method installs a detection line for detecting leaks in the pipeline, and estimates a point at which a leak has occurred based on a measured voltage of the detection line. [0003] figure 1 Describe conventional leak detection equipment. see figure 1 , the conventional leak detection eq...
