Liquid leakage detection line

Abstract

The present invention provides a liquid leakage detection line (P2) for shortening color development time and preventing nonuniform color development, which is formed by intertwisting two conductors (11) covered by an insulating weaved object, and a linear color development body (13) and is provided with an external weaved object (14), wherein the color development body (13) dyes a liquid non-absorbent line weaved object (13b') with a liquid soluble colorant, and the periphery of the color development body is covered by a liquid non-absorbent line weaved object (13c). The color development body (13) is formed by a liquid non-absorbent line weaved object (13b'), the lines do not contains the colorant, and the outer circumferential surface of the color development body (13) is covered by the colorant for dyeing, especially the weaved object (13b') is dyed. Therefore, the colorant is arranged among various fibers of the weaved object, the colorant is large in amount, rapid in color development speed, and bright in color development degree. The liquid leakage directly enters into the coloring layer of the colorant, and the colorant is smoothly dissolved, thereby shortening the time from liquid leakage generation to the coloring layer and to the time for seeing color development on the external weaved object.

Description

Technical field [0001] The present invention relates to a liquid leakage detection line for detecting water leakage in a building and liquid leakage during storage and transportation of chemical liquids and the like. Background technique [0002] For computer rooms, storage rooms for various materials, etc., if water adheres to or leaks on the walls, floors, various equipment surfaces, piping joints, etc. inside the building, it may cause damage to the building floor. Corrosion, misoperation of various equipment, deterioration of materials, etc. In addition, when storing or transporting various liquids such as water, sulfuric acid, hydrochloric acid, and other chemicals, or crude oil, petroleum, gasoline, and other oils, leakage of the liquid may cause economic losses or accidents. [0003] Therefore, a liquid leakage detection line is installed on the wall surface inside the building as a device for detecting the water leakage or liquid leakage (both are referred to as “leakage” ...
