ため、非常に有効な漏水検知装置となるものである。The present invention uses the above-described configuration to compare the minute flow in the water supply pipe caused by water leakage with the water temperature in the water supply pipe at the inlet of the heating device installed in the middle of the water supply pipe and the water temperature in the water supply pipe at the outlet of the heating device. It can be detected by doing this. In other words, water leakage can be detected by utilizing the phenomenon that when there is a small flow in the water supply pipe, the water temperature in the water supply pipe at the outlet of the heating device becomes higher than the water temperature in the water supply pipe at the inlet of the heating device. . For this reason, conventional water leakage detection devices detect water leakage by detecting changes in the internal pressure within the water supply pipes.Due to the piping configuration, the water leakage detection part had to be in a sealed structure, making it extremely difficult to detect water leakage. Whereas previously it was only possible to detect water leaks in certain locations, by using the configuration of the present invention, it is now possible to detect water leaks in a wide range of locations with simple water piping, and the usability is improved, making it extremely effective. This is a water leakage detection device.
