[0020] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0021] The following describes, in conjunction with the accompanying drawings, a metal hose for a heat exchange system that is easy to replace, provided by some embodiments of the present invention.

[0022] Example:

[0023] Combine Figure 1-3As shown, the utility model provides a metal hose for a heat exchange system that is easy to replace, including a metal hose 100, a solid joint and a movable joint. The two ends of the metal hose 100 are respectively connected to the fixed joint and the movable joint. The solid joint includes a solid connecting pipe 210 connected to the end of the metal hose 100, a coarse filter pipe 230 arranged in the middle of the solid connecting pipe 210, and a coarse filter element 240 filled in the coarse filter pipe 230. A connecting flange 220 is provided on the inner side of the solid connecting pipe 210. The two ends of the coarse filter pipe 230 are fixedly connected to the middle of the solid connecting pipe 210 through the connecting flange 220. The movable joint includes a movable pipe 310 connected to the other end of the metal hose 100, a retaining ring 320 slidably connected to the movable pipe 310, and a connecting rod 330 connected to the side of the retaining ring 320. The end of the connecting rod 330 is clamped with a connecting sleeve 331, and the connecting rod 330 is located inside the connecting sleeve 331 The spring 332 is sleeved on the position of the movable tube 310, the movable connecting tube 340 is connected to the other end of the connecting rod 330 and corresponds to the movable tube 310, and the fine filter tube 350 is clamped between the movable tube 310 and the movable connecting tube 340. There are two retaining rings 320, which are respectively sleeved on the movable tube 310 and the movable connecting tube 340, and the middle of the retaining ring 320 is connected with a threaded part. The interior of the fine filter tube 350 is filled with a fine filter element 351, and plug connectors 352 are installed at both ends of the fine filter tube 350. A sealing ring 353 is installed on the plug connector 352, and a positioning plate 354 is provided at the connection between the fine filter tube 350 and the plug connector 352. By providing the sealing ring 353, the sealing of the connection can be effectively ensured to avoid leakage, thereby improving the reliability of the structure. The filter hole of the coarse filter element 240 is larger than the filter hole of the fine filter element 351, and a sewage outlet 360 is provided at the bottom of the movable tube 310.

[0024] Specifically, the movable tube 310 and the movable connecting tube 340 are connected by using the connecting rod 330, and the structural characteristics of the spring 332 can be used to pull the two springs 332 toward the connecting sleeve 331, thereby shrinking the distance between the movable tube 310 and the movable connecting tube 340, thereby clamping the fine filter tube 350. Therefore, when replacing, you only need to pull the movable tube 310 and the movable connecting tube 340 apart to remove the fine filter tube 350 for replacement, which is convenient and quick.

[0025] The working principle and usage process of the present invention are as follows: first, the solid joint and the movable joint are respectively connected to the water inlet and the water outlet of the heat exchanger, and the use is started. When the water flow from the outlet flows through the coarse filter element 240 and the fine filter element 351, it will be filtered, and the mud and other impurities therein will be filtered out. In the case that the fine filter tube 350 is blocked, the movable tube 310 is pulled to expand the distance between the movable tube 310 and the movable connecting tube 340. At this time, the fine filter tube 350 will be detached from the ends of the movable tube 310 and the movable connecting tube 340. The blockage can be solved by removing the fine filter tube 350 and replacing it with a new fine filter tube 350. Finally, the sewage outlet 360 is opened regularly for sewage discharge, which can effectively extend the service life of the fine filter tube 350.

[0026] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
