If the speed needs to be adjusted further, the movable ratchet rod 14 is pressed down, the rotating disc 2 is rotated further, when the rotating disc rotates further counterclockwise from the horizontal position to the lower limit position, as shown in fig. 5, the main stream is accelerated by the branch, and the second branch flow plate 6 slides downward and is no longer located in the middle of the first main flow plate 301 and the first branch flow plate 302 in the process of rotating the rotating disc counterclockwise, so that the flow rates of the main stream B and the branch stream C are no longer the same, the flow rate of the main stream is increased, the flow rate of the branch stream is decreased, and the flow rate of the outflow stream is unchanged, and therefore, the speed of the liquid outlet is increased further.
When the liquid flow rate is too high and causes the patient to be untimely, the movable ratchet rod 14 needs to be moved downwards to fix the flow area of the liquid outlet, then the rotating disc 2 is rotated clockwise, the rotating disc 2 drives the third flow branch plate 5 to rotate clockwise, the main flow is blocked by the main flow, the second flow branch plate 6 can slide upwards by the clockwise rotation of the third flow branch plate 5, the flow of the main flow is increased at the moment, the flow of the main flow is reduced, when the third flow branch plate 5 returns to the initial position, the flow of the main flow is the same as that of the branch flow, when the third flow branch plate 5 continues to rotate clockwise from the initial position to the limit, the flow of the branch flow is greater than that of the main flow, as shown in fig. 6, the flow rate of the main flow is reduced, the flow rate of the branch flow is increased, the blocking of the main flow by the branch is increased, and the flow rate of the outlet is reduced. Can be according to patient's actual conditions when using, when the velocity of flow is fast, the clockwise rotation rolling disc makes the velocity of flow reduce, and when the velocity of flow was slow, counter-clockwise rotation rolling disc made the velocity of flow accelerate.
