The gap 4 is filled with a sealing ring 5, which is made of elastic material, and the outer surface of the sealing ring 5 is flush with the outer surface of the connecting flange 3, and the sealing ring 5 has a circle of water-permeable gaps 5a connected to the gap 4.

[0019] The outer part of the sealing ring 5 is provided with an upper connecting ring 6 and a lower connecting ring 7 which are connected to each other in cooperation, and the upper connecting ring 6 and the lower connecting ring 7 are connected by bolts. The inner parts of the upper connecting ring 6 and the lower connecting ring 7 are provided with water collecting channels 8 respectively, and the two water collecting channels 8 are connected to each other. The inner sides of the upper connecting ring 6 and the lower connecting ring 7 are provided with convex strips 9 respectively, and the two convex strips 9 can cooperate to extend into and seal the whole circle of water permeable seam 5a, such as Figure 3 The two convex strips 9 are also provided with water-permeable openings 10 for connecting the water-permeable seam 5a and the water collecting channel 8, and the length of the water-permeable openings 10 extends along the length direction of the convex strips 9 and passes through the two ends of the convex strips 9.

[0020] In this embodiment, the inner surfaces of the upper connecting ring 6 and the lower connecting ring 7 are both provided with sealing gaskets 14 for sealingly fitting with the outer surface of the connecting flange 3 to ensure sealing performance.

[0021] Furthermore, the bottom of the lower connecting ring 7 is also connected to a water outlet pipe 11 connected to the water collecting channel 8, and a detection tube 12 is connected to the inner thread of the water outlet pipe 11. In this embodiment, a limiting gasket 15 is provided on the detection tube 12, and a sealing ring 16 that fits tightly with the limiting gasket 15 is provided in the water outlet pipe 11. When the detection tube 12 is screwed and installed, the limiting gasket 15 stops when it fits with the sealing ring 16. A detection sensor 13 is provided in the detection tube 12 for detecting whether there is leakage.

[0022] When installing the detection device of the utility model, firstly, the sealing ring 5 is sleeved on the gap 4 to fill the gap 4. The sealing ring 5 is made of elastic material, has high elasticity, good sealing performance, and is easy and quick to install. The leaked liquid from the gap 4 can be led out through the water-permeable slit 5a. Then, the upper connecting ring 6 and the lower connecting ring 7 are quickly connected to the outside of the sealing ring 5 by bolts, and the convex strip 9 is aligned with the water-permeable slit 5a and inserted for installation. The leaked liquid from the water-permeable slit 5a can enter the water collection channel 8 through the water-permeable port 10. The water collection channels 8 of the two connecting rings are interconnected. The leaked liquid flows downward under the action of gravity and is collected in the detection tube 12 through the outlet pipe 11. The detection sensor 13 is used to detect whether there is a leak. The maintenance personnel can also unscrew the detection tube 12 to check whether there is a leak and the amount of leaked liquid at any time, so as to facilitate the timely maintenance of the heat exchanger.
