Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Embodiment: As shown in the attached Figures 1 - 7A hemodialysis ultra-pure liquid supply speed regulating device shown in the figure includes a main supply pipeline 1. At least one branch pipeline 2 is fixedly connected to the outside of the main supply pipeline 1. In this embodiment, four groups are provided. A conveying pipeline 3 is provided at one end of the branch pipeline 2. An annular plate 11 is provided between the conveying pipeline 3 and the branch pipeline 2. Bellows 5 are fixedly connected between the annular plate 11 and the conveying pipeline 3, and between the branch pipeline 2 and the annular plate 11. The function of the bellows 5 is that when the conical rod 8 is adjusted, the bellows 5 can play a role in buffering compression or stretching. A conical rod 8 is also fixedly connected inside the annular plate 11. A connecting rod 9 is fixedly connected to the end of the conical rod 8. A connecting frame 10 is fixedly connected to the outside of the connecting rod 9. The connecting frame 10 is fixedly connected to the annular plate 11. The conical rod 8 is located in the bellows 5. A conical groove 7 is provided in the branch pipeline 2. When the conical rod 8 is completely fitted with the conical groove 7, the channel of the branch pipe is closed. When the conical rod 8 leaves the conical groove 7, it can be opened;

[0031] In addition, an adjusting sleeve 6 is sleeved outside the conveying pipeline 3. The adjusting sleeve 6 is rotatably connected to the annular plate 11. Specifically, an annular sliding strip 12 is fixedly connected to the inner wall of the annular plate 11. An annular sliding rail 13 is fixedly connected to the outside of the adjusting sleeve 6. The annular sliding strip 12 is slidably connected in the annular sliding rail 13. An adjusting member is also provided outside the conveying pipeline 3. In this embodiment, the adjusting member is a thread 4 provided on the outer wall of the conveying pipeline 3 and the inner wall of the adjusting sleeve 6. The adjusting sleeve 6 is threadedly connected to the conveying pipeline 3. For the convenience of rotation, a plurality of groups of dial rods are fixedly connected to the outside of the adjusting sleeve 6. The adjusting sleeve 6 can rotate and move outside the conveying pipeline 3 through the thread 4. In addition, since the adjusting sleeve 6 is rotatably connected to the annular plate 11, when the adjusting sleeve 6 moves, the annular plate 11 will also be driven to move synchronously. When the annular plate 11 moves, the conical rod 8 can be driven to move left and right, so as to realize the adjustment of the internal channel of the branch pipe, and thus complete the adjustment of the liquid supply speed.

[0032] For those skilled in the art to fully understand the technical solution, the following overview is made in this embodiment:

[0033] During use, dialysis fluid is provided through the main supply pipeline 1, and then the dialysis fluid is transported into the dialysis machine through the branch pipeline 2 and the conveying pipeline 3. At the same time, when adjusting the liquid supply speed, only need to rotate the adjusting sleeve 6, so that the adjusting sleeve 6 can rotate and move outside the conveying pipeline 3 through the thread 4. In addition, since the adjusting sleeve 6 is rotatably connected to the annular plate 11, when the adjusting sleeve 6 moves, the annular plate 11 will also be driven to move synchronously. When the annular plate 11 moves, the conical rod 8 can be driven to move left and right. Refer to the appendix Figure 4As shown, when the conical rod 8 is fully fitted with the conical groove 7, the branch pipe can be closed. If the conical rod 8 leaves the conical groove 7, the internal passage of the branch pipe can be opened until it is adjusted to a suitable position, and the adjustment of the liquid supply speed can be completed. When the annular plate 11 pulls the conical rod 8, the corrugation will also be stretched, so it will not affect the medium transportation between the branch pipe and the conveying pipe 3. Embodiment 2

[0034] Reference appendix Figures 6 - 7 In this embodiment, which is different from Embodiment 1, the adjusting member includes a positioning groove 14 provided on the conveying pipe 3 and a positioning screw 15 with a thread 4 passing through the adjustment. A plurality of positioning blind holes are provided at the position of the positioning screw 15 corresponding to the positioning groove 14.

[0035] For the above technical solution, the following explanation is made: The adjusting sleeve 6 can be pushed to drive the annular plate 11 to move, thereby driving the conical rod 8 to move, adjusting the position of the conical rod 8 in the conical groove 7, and completing the adjustment of the liquid supply speed. After the adjustment is completed, then rotate the positioning screw 15 to make the positioning screw 15 snap into the positioning blind hole in the positioning groove 14 to form a fixation.
