[0023] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0024] The first implementation method:

[0025] Figure 1-6 A control device for a chilled water secondary pump is shown, comprising a water pipe 1, an arc groove 2 is provided at the outer end of the water pipe 1, a plug-in pipe 3 is movably plugged into the inner part of the arc groove 2, a control plate 4 is rotatably connected to the inner part of the plug-in pipe 3, a round pipe 5 is fixedly connected to the outer end of the control plate 4, a filter plate 6 is fixedly connected to the inner wall of the plug-in pipe 3, a round groove 7 is provided on the inner wall of the arc groove 2, the inner bottom wall of the round groove 7 is fixedly connected to the lower end of a compression spring 8, a lifting rod 9 is fixedly connected to the upper end of the compression spring 8, and the outer end of the round pipe 5 is provided with a There are multiple limit grooves 10 that are movably plugged with the lifting rod 9. A circular hole is opened at the outer end of the plug-in tube 3. A sealing ring 11 is fixedly connected to the inner wall of the circular hole. The inner wall of the sealing ring 11 is rotatably connected to the outer end of the circular tube 5. The left and right ends of the plug-in tube 3 are fixedly connected with sealing rings 12. The ends of a pair of sealing rings 12 that are away from each other are both fitted with the inner wall of the arc groove 2. The left and right ends of the lifting rod 9 are fixedly connected with a slider 13. A pair of sliding grooves 14 that are slidably connected to the slider 13 are opened on the inner wall of the circular groove 7.

[0026] This solution can be achieved. When adjusting the water flow, the lifting rod 9 needs to be moved downward so that its lower end continues to extend into the circular groove 7. At the same time, the compression spring 8 continues to shrink. When the lifting rod 9 is separated from the circular tube 5, the circular tube 5 is rotated to drive the regulating plate 4 to rotate together. The purpose of regulating the water flow is achieved by adjusting the inclination of the regulating plate 4 in the plug-in tube 3. After adjusting the water flow, the circular tube 5 is fixed by the lifting rod 9, and then the regulating plate 4 is fixed. At the same time, when water flows in the water pipe 1, the filter plate 6 can be used to filter impurities in the water. After filtering for a period of time, the personnel need to take the plug-in tube 3 out of the arc groove 2 and clean the filtered impurities to prevent the impurities from blocking the filter plate 6. Therefore, the device is not only convenient for personnel to adjust the size of the water flow, but also can filter the water flow to improve its cleanliness.

[0027] The second implementation method:

[0028] Based on the first embodiment, this embodiment adds structures such as a moving tube 16 and a limiting tube 17, and the rest of the parts are consistent with the first embodiment.

[0029] Figure 7-8 It is shown that a pair of adjusting grooves 15 are provided at the upper end of the plug-in tube 3, and a movable tube 16 is slidably connected inside the adjusting grooves 15. The ends of the pair of movable tubes 16 that are away from each other are fixedly connected to a limiting tube 17. A reinforcement groove 18 that is movably connected to the limiting tube 17 is provided on the inner wall of the arc groove 2. The end of the limiting tube 17 away from the movable tube 16 is coated with a magnetic coating 19, and a magnetic coating 20 is coated on the inner wall of the reinforcement groove 18. A pair of sliding blocks 21 are fixedly connected to the outer end of the movable tube 16, and a sliding groove 22 that is slidably connected to the sliding block 21 is provided on the inner wall of the adjusting groove 15.

[0030] This solution can be achieved by pushing a pair of movable tubes 16 to move them to the side away from each other after the plug-in tube 3 is inserted into the arc groove 2. When the movable tube 16 moves, it will drive the limiting tube 17 to move together, and continue to push the movable tube 16 until one end of the limiting tube 17 enters the reinforcement groove 18, and the magnetic coating 19 and the magnetic coating 2 20 are adsorbed together, thereby improving the stability of one end of the limiting tube 17 in the reinforcement groove 18. The limiting tube 17 can be used to prevent the plug-in tube 3 from shaking in the arc groove 2 during use, thereby improving the stability of the plug-in tube 3.

[0031] In view of current practical needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
