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 metabolism; radiators and branch pipes are canceled, laying underground does not occupy the living room space, and the use area is increased on the side; the floor heating has good stability, no corrosion, and no artificial damage , the service life is synchronized with the building.
然而，地暖是一种隐蔽的工程，埋在地板之下，检测和维修都比较困难。即使在铺设时使用耐压耐温耐腐蚀，热稳定性好的材料也不能保证终身不出现故障。而一旦出现泄漏的故障往往很难发现，等到被发现的时候，可能已经造成了地板泡水，设备进水等后果，甚至可能影响到周围其他住户，不仅自己要承受损失还可能造成其他用户的损失。However, floor heating is a hidden project, buried under the floor, and it is difficult to detect and maintain. Even if pressure-resistant, temperature-resistant, corrosion-resistant, and thermally stable materials are used for laying, there is no guarantee that there will be no failures for life. Once a leakage fault occurs, it is often difficult to find it. When it is discovered, it may have caused consequences such as water soaking in the floor and water ingress in the equipment, and may even affect other residents around. loss.

管道检测装置安装完成后，输入第一导电束31和第二导电束32的布局信息至控制模块4中，通过对比布局图找出泄漏位置。After the pipeline detection device is installed, input the layout information of the first conductive bundle 31 and the second conductive bundle 32 into the control module 4, and find out the leakage location by comparing the layout diagram.
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员，在不脱离本发明构思的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明保护范围内。The above is only a preferred embodiment of the present invention, it should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, some improvements and modifications can also be made, and these improvements and modifications should also be considered Within the protection scope of the present invention.
