[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] A reversing valve with flow rate regulation function, such as Figure 1 The device includes a reversing valve body 1, a regulating pipe 2 connected to the reversing valve body 1, and a mounting box 3 connected to the regulating pipe 2 horizontally on one side of the outer wall of the regulating pipe 2. The opening of the mounting box 3 faces the regulating pipe 2. The mounting box 3 is provided with a regulating component for adjusting the flow rate of the medium in the regulating pipe 2. A drive motor 4 for driving the regulating component is detachably connected to the reversing valve body 1.

[0019] like Figure 1 When in use, the medium is injected into the reversing valve body 1 through the regulating pipe 2. During the medium injection process, the regulating component is driven by the drive motor 4 to adjust the liquid flow rate in the regulating pipe 2. Since the drive motor 4 is installed on the reversing valve body 1, it is convenient to inspect or maintain the drive motor 4. When inspecting or maintaining the drive motor 4, it is not necessary to stop the medium injection.

[0020] The main body 1 of the reversing valve can be replaced with the reversing valve body of a reversing valve with flow rate regulation function as described in application number CN202322148524.2. In this case, the regulating pipe 2 is connected to the inlet groove on the reversing valve body.

[0021] like Figure 2 and Figure 3 The adjusting component includes an adjusting plate 5 that is horizontally slidably connected inside the mounting box 3. The side of the adjusting plate 5 near the inner wall of the adjusting tube 2 is arc-shaped. The side of the adjusting plate 5 away from the adjusting tube 2 is provided with a threaded groove 6. A screw 7 is threadedly connected inside the threaded groove 6. One end of the screw 7 extends outside the threaded groove 6 and is rotatably connected to the bottom of the mounting box 3. A rotating shaft 8 is coaxially provided on the side of the screw 7 away from the bottom of the threaded groove 6. The end of the rotating shaft 8 away from the screw 7 passes through the mounting box 3 and extends outside the mounting box 3. The rotating shaft of the drive motor 4 is connected to the rotating shaft 8 through a connecting component. The connecting component includes a transmission groove 9 on the side of the rotating shaft 8 near the drive motor 4. A transmission block 10 is embedded in the transmission groove 9. The transmission block 10 is fixedly connected to the rotating shaft of the drive motor 4.

[0022] like Figure 2 and Figure 3 The rotating shaft of the drive motor 4 drives the rotating shaft 8 to rotate through the cooperation of the transmission block 10 and the transmission groove 9. The rotating shaft 8 drives the screw 7 to rotate. At this time, through the cooperation of the screw 7 and the threaded groove 6, the adjusting plate 5 can be pushed to move horizontally in the mounting box 3. When the adjusting plate 5 moves closer to the adjusting pipe 2 and one end of the adjusting plate 5 extends into the adjusting pipe 2, the transmission space of the adjusting pipe 2 can be reduced by the adjusting plate 5 to increase the flow rate while keeping the medium injection volume unchanged. Conversely, the transmission space increases and the flow rate decreases, thus achieving the purpose of speed regulation. When the drive motor 4 is inspected or maintained, the drive motor 4 can be removed from the reversing valve body 1 and the transmission block 10 can be removed from the transmission groove 9. At this time, the connection between the rotating shaft of the drive motor 4 and the rotating shaft 8 can be disconnected, which facilitates the inspection, maintenance or replacement of the drive motor 4. It is simple and convenient to use.

[0023] like Figure 2 and Figure 3A rotating ring 12 is coaxially rotatably connected to the outer wall of the regulating pipe 2, and a conical gear ring 13 is coaxially provided at the bottom end of the rotating ring 12. The rotating ring 12 is located above the mounting box 3. A conical gear 14 that meshes with the conical gear ring 13 is provided on the rotating shaft 8. The purpose of this arrangement is that when the rotating shaft 8 rotates, the rotating shaft 8 will drive the rotating ring 12 to rotate through the cooperation of the conical gear ring 13 and the conical gear ring 14. During the process of removing the drive motor 4 for inspection, maintenance or replacement, the rotating ring 12 can be rotated, and the rotating shaft 8 will be driven to rotate through the cooperation of the conical gear ring 13 and the conical gear ring 14. In turn, the adjusting plate 5 will be pushed to move horizontally through the cooperation of the screw 7 and the threaded groove 6, thereby adjusting the flow rate of the medium in the regulating pipe 2. Through the above process, even if the drive motor 4 is removed, the flow rate of the medium in the regulating pipe 2 can be manually adjusted, which is simple and convenient to use.

[0024] like Figure 2 and Figure 3 The rotating ring 12 includes a fixed ring 15 and a circular ring 16. The fixed ring 15 is coaxially fixedly connected to the outer wall of the adjusting tube 2, and the circular ring 16 is coaxially rotatably connected to the outer wall of the fixed ring 15. A conical gear ring 13 is provided at the bottom end of the circular ring 16. The top end of the fixed ring 15 is provided with several scale lines 17, and each scale line 17 is evenly distributed along the circumference of the fixed ring 15. The top end of the circular ring 16 is provided with a pointer 18 facing the scale lines 17. The outer wall of the circular ring 16 is provided with several anti-slip ridges 19, and each anti-slip ridge 19 is evenly distributed along the circumference of the circular ring 16. The purpose of this arrangement is that when the rotating shaft 8 rotates, the rotating shaft 8 will drive the circular ring 16 to rotate on the fixed ring 15 through the cooperation of the conical gear 14 and the conical gear ring 13. At this time, by cooperating with the pointer 18 on the ring 16 and the scale line 17 on the fixed ring 15, it is easy to know the rotation angle of the ring 16, thus making it easy to know the number of rotations of the shaft 8 and the screw 7, and further making it easy to know the distance that the screw 7 pushes the adjusting plate 5 to move horizontally through the threaded groove 6. At this time, by knowing the distance that the adjusting plate 5 moves horizontally, it is easy to know the situation of the transmission space inside the adjusting tube 2. For example, when the adjusting plate 5 is completely inside the mounting box 3, the shaft 8 and the screw 7 rotate one revolution, the ring 16 rotates 10 degrees on the fixed ring 15, and the adjusting plate 5 moves horizontally from the mounting box 3 into the adjusting tube 2 by 0.5mm through the cooperation of the threaded groove 6 and the screw 7. At this time, the transmission space inside the adjusting tube 2 is closed by one-eighteenth. During the process of removing the drive motor 4 for inspection, maintenance or replacement, the ring 16 can be rotated, and the rotating shaft 8 is driven to rotate through the cooperation of the bevel gear 14 and the bevel gear ring 13. The ring 16 can be easily rotated through the anti-slip convex strip 19, which is simple and convenient to use.

[0025] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
