The inlet pipe flange 2 and the fresh water pipe flange 3 are circumferentially connected by multiple connecting plates 4 evenly distributed around the circumference. A positioning component perpendicular to the connecting plates 4 positions and connects the connecting plates 4 and the inlet pipe flange 2 and the fresh water pipe flange 3 into a single unit. Multiple connecting plates 4 are evenly distributed around the circumference to achieve circumferential positioning of the inlet pipe flange 2 and the fresh water pipe flange 3. The positioning component is perpendicular to the connecting plates 4 and is used to position and connect the connecting plates 4 and the inlet pipe flange 2 and the fresh water pipe flange 3 into a single unit. The connecting plates 4 are provided with a limiting component whose inner end is connected to the positioning component and is used to axially limit the positioning component. The inlet pipe flange 2 and the fresh water pipe flange 3 are composed of multiple connecting plates 4. The connecting plate 4, positioning component, and limiting component are detachably connected as one unit. The limiting component is used to axially position the positioning component to prevent it from loosening, thereby ensuring the stability of the connection between the water inlet pipe flange 2 and the freshwater pipe flange 3. In the above structure, multiple connecting plates 4 are used to circumferentially position and connect the water inlet pipe flange 2 and the freshwater pipe flange 3. The positioning component and the limiting component used to limit the positioning component are used to quickly connect the connecting plate 4 and the water inlet pipe flange 2 and the freshwater pipe flange 3. This solves the technical defects of bolted flange connections, such as cumbersome disassembly and assembly, low efficiency, easy corrosion and stripping, high maintenance costs, and inconvenient inspection. It realizes the rapid disassembly and assembly of flanges, greatly reduces the burden of personnel operation, improves maintenance and replacement efficiency, reduces maintenance costs, eliminates the limitations of traditional bolted connections, and brings convenience to daily equipment inspection, maintenance, and troubleshooting.

The disassembly and assembly operation part of the positioning assembly is the rotating block 12, and the disassembly and assembly operation part of the limiting assembly is the pull block 18.

[0019] The disassembly process is as follows: 1) Hold the pull block 18 and pull the pull rod 13 outward, the pull rod 13 drives the movement plate 17 to move outward to compress the spring 14 until the inner end of the pull rod 13 is separated from the circular groove 11 on the positioning rod 6 to release the axial limiting of the positioning assembly; 2) Hold the rotating block 12 and rotate the positioning rod 6 outward to overcome the attraction force of the magnetic attraction block 7 and take out the positioning rod 6 from the insertion hole 9 and the positioning hole 8. 3) Take out the plurality of connecting plates 4 in the direction of the card slot 5, that is, the water inlet pipe flange plate 2 and the fresh water pipe flange plate 3 can be disassembled, and the disassembly is completed.
