[0039] In the specific use process of this embodiment, when the water flow needs to be speed-regulated, first, the motor 812 is started through an external PLC. The output shaft of the motor 812 rotates to drive the coaxial rotating shaft 813 to rotate. The rotation of the rotating shaft 813 drives the same-side gear 811 coaxially fixed thereto to rotate. The rotation of this gear 811 drives another meshing gear 811 to rotate. The rotation of the other gear 811 drives the coaxial fixed rotating rod 810 to rotate. The rotation of the rotating rod 810 drives the coaxial fixed roller 82 to rotate. The rotation of the roller 82 drives the coaxial fixed cylindrical cam 83 to rotate. The rotation of the cylindrical cam 83 drives the spiral chute on its outer wall to rotate. The rotation of the cylindrical cam 83 drives the sliding column 88 slidingly connected to the chute on its outer wall to move. The sliding column 88 moves in a straight line in the vertical direction under the guiding action of the moving block 84, the guiding block 89, and the guiding groove on the right surface of the vertical plate end of the vertical plate 81. The movement of the sliding column 88 drives the moving block 84 fixed thereto to move. The movement of the moving block 84 drives the moving rod 85 fixed thereto to move. The movement of the moving rod 85 drives the connecting rod 86 fixed thereto to move. The movement of the connecting rod 86 drives the sliding rod 87 fixed thereto to move. The movement of the sliding rod 87 drives the valve plate 7 fixed thereto. When the valve plate 7 moves to an appropriate height position, the motor 812 is turned off through an external PLC, and finally the regulation of the water flow rate is completed.
