[0024] Please see the attached Figure 1-6 The purpose of this embodiment is to provide a heating pipe fault detection system, including: multiple pipe sections connected in sequence, each pipe section is provided with an inner layer pipe 11 and an outer layer pipe 12, an intermediate layer 13 is provided between the inner layer pipe 11 and the outer layer pipe 12, the intermediate layer 13 is hollow, and both ends of the intermediate layer 13 are sealed; an overflow pipe 14 is provided on the outer layer pipe 12, the overflow pipe 14 passes through the outer layer pipe 12 and extends into the intermediate layer 13, and the overflow pipe 14 is connected to the intermediate layer 13; a first sensor 141 and a second sensor 142 are provided inside the overflow pipe 14, and the first sensor 141 and the second sensor 142 are arranged up and down.

[0025] In this embodiment, the outer tube 12 is provided with an outer tube interlayer 123, and a dye is filled in the outer tube interlayer 123. A third sensor 143 is further provided inside the overflow tube 14, and the third sensor 143 is a color sensor.

[0026] It should be noted that the structure of each pipe segment is the same, and a boss 15 is provided at one end of the pipe segment, and a groove 16 is provided at the other end of the pipe segment; the boss 15 of the pipe segment is inserted into the groove 16 of the adjacent pipe segment. The outer portion of the connection between adjacent pipe segments is provided with a sealing ring 4, and a fastening device is provided on the outside of the sealing ring 4. Taking three pipe segments as an example, the first pipe segment 1, the second pipe segment 2 and the third pipe segment 3, the boss 15 of the first pipe segment 1 is inserted into the groove 16 of the second pipe segment 2, and the boss 15 of the second pipe segment 2 is inserted into the groove 16 of the third pipe segment 3. The connections between the first pipe segment 1, the second pipe segment 2 and the third pipe segment 3 are all provided with a sealing ring 4, and the fastening device on the outside of the sealing ring 4 ensures that the entire pipeline does not leak. It should be noted that the first sensor 141, the second sensor 142 and the third sensor 143 are all electrically connected to the control center.

[0027] When the inner tube 11 leaks, the water flows into the middle layer 13 and flows out from the bottom to the top through the overflow pipe 14. Since the water flows through the second sensor 142 and the first sensor 141 in turn, it can be determined that the water flows out from the inner tube 11. If external water flows into the overflow pipe 14, it passes through the first sensor 141 and the second sensor 142 in turn. According to the order in which the two sensors are triggered, it can be determined whether the inner tube 11 is leaking; if the outer tube 12 leaks, the dye in the outer tube interlayer 123 will pass through the third sensor 143 with the external water flow, that is, when the water flows through the color sensor, it can be determined that the outer tube 12 is leaking. If the leakage of the outer tube 12 is not serious or the external water flow is insufficient, even if the color sensor does not detect the colored water flow, since the inner tube 11 is not leaking at this time, it does not affect the normal use of the pipeline. When both the inner tube 11 and the outer tube 12 leak, water will flow through the three sensors in the overflow tube 14. Generally, the water flow entering the overflow tube 14 through the middle layer 13 is greater than the external water flow. The three sensors can detect the leakage of the pipeline in time.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
