[0027] In the above structure, through the arrangement of the base plate 1, fixing bar 1 2, positioning bolt 1 3, fixing bar 2 4, valve 8, connecting shell 9, connecting rod 10, and docking groove 11, after the user installs the power source 7 on the base plate 1, the connecting rod 10 can be plugged into the docking groove 11 with the output shaft of the power source 7 so that the output shaft of the power source 7 can drive the ball valve to rotate when it rotates, so that when the user needs to adjust the water flow pressure, there is no need for manual operation by the user, thereby improving the automation and practicality of the adjustment device.

[0028] In a preferred embodiment: a docking groove 11 is provided at one end of the connecting rod 10 away from the valve 8, a fixing strip 2 is tightly fitted on the outer wall of the valve 8, a positioning bolt 3 passes through the top of the fixing strip 2, a nut 12 is threadedly connected to the outer wall of the positioning bolt 3, a fixing strip 4 is tightly fitted on the top of the bottom plate 1, a fastening ring 5 is tightly fitted on the top of the fixing strip 4, a positioning bolt 13 is sleeved on the inner wall of the fastening ring 5, a nut 6 is threadedly connected to the outer wall of the positioning bolt 13, a power source 7 is tightly fitted on the bottom of the fixing strip 4, the shape of the output shaft of the power source 7 is matched with the shape of the docking groove 11, a ball valve is rotatably connected to the inner wall of the valve 8, and the ball valve is fixedly connected to the output shaft of the power source 7 through the connecting rod 10.

[0029] In the above structure, through the provided docking groove 11 and the power source 7 structure, when the user installs the power source 7, the output shaft of the power source 7 can be directly docked with the docking groove 11, and the shape of the output shaft of the power source 7 can enable the output shaft to synchronously drive the connecting rod 10 to rotate when rotating, so that the ball valve can rotate, thereby achieving the effect of automatically adjusting the internal water pressure of the valve 8, thereby improving the automation and adjustment accuracy of the device.

[0030] In a preferred embodiment: the fixing strip 2 is fixedly connected to the base plate 1 through the positioning bolt 3 and the nut 2 12, and the valve 8 is fixedly connected to the base plate 1 through the fixing strip 2, the number of valves 8 is two, and the interiors of the two valves 8 are connected.

The use cost of the servo motor is lower than that of the steering gear, which further reduces the production cost of the device on the basis of ensuring the normal use of the device.

[0038] Working principle: first, after the user fixes the valve 8, the output shaft of the power source 7 is aligned with the docking groove 11, and then the power source 7 is pushed to move so that the output shaft of the power source 7 is plugged into the docking groove 11, and then the power source 7 is fixed to the base plate 1 using the fixing strip 2 4, the fastening ring 5 and the positioning bolt 2 13, and then the ratio of concentrated water and pure water in the system is set by the control main board. During operation, the pure water flow rate and the concentrated water flow rate are detected by the pure water flow meter 15 and the concentrated water flow meter 16. If the concentrated water ratio is not within the set interval, the control main board will control the first power source 7 to operate, so that the concentrated water flow rate is within the set interval. If the working pressure is not within the interval, the control main board will control the second power source 7 to operate, so that the working pressure is within the set interval, and the ratio of concentrated water and pure water is calculated at the same time. If it is not within the set interval, repeat the above operation until the ratio of pure water and concentrated water is adjusted to the set interval, and the pressure sensor 14 will detect the working pressure in real time, and cooperate with the control main board to control the second power source 7 to adjust the working pressure, so as to provide protection for the pipeline and accessories.
