Abstract

The invention discloses a floor heating pipeline liquid leak detection device which comprises an insulating detection module. One end of the insulating detection module is connected with a position detection module which is tightly attached to a floor heating pipeline for arrangement, and the other end of the insulating detection module is connected with a control module. One output end of the control module is connected with an alarm module, and the other output end of the control module is connected with a liquid inlet cut-off module arranged at the water inlet end of the pipeline. The position detection module comprises a first conducting tow, a second conducting tow and a first partition layer used for separating the first conducting tow from the second conducting tow. The first conducting tow and the second conducting tow are insulated when being dried and can achieve breakover when being immersed in water. The control module processes two sets of output impedances, so that the leak position and leak amount of the pipeline are obtained. According to the floor heating pipeline liquid leak detection device, the leak position and leak amount of the pipeline can be detected by processing the resistance values of the immersed first conducting tow and second conducting tow, the sensitivity is high, the design is reasonable, the structure is simple and operation is easy.

Description

technical field [0001] The invention belongs to the technical field of floor heating, and in particular relates to a liquid leakage detection device and a detection method of a floor heating pipeline. Background technique [0002] Underfloor heating uses the entire floor as a heat sink, and the entire heating gradient is gradually heated from bottom to top. Compared with traditional convection heating, it can give people a comfortable feeling of warming the feet and cooling the head, which is in line with the traditional Chinese medicine "warming the feet and top Cool" fitness theory; heat is concentrated at the height where the human body benefits, reducing energy waste, and can make full use of low-temperature hot water resources or use electricity price policies to reduce operating costs, saving at least 20% of energy consumption compared to other heating methods; air It is clean and will not cause convection of dirty air; it can improve blood circulation and promote meta...
