Preferably, the three-core reverse osmosis water purification system has a water purification capacity in the range of 200 gallons per hour.
In the present disclosure, the water inlet pipeline 10 is connected to an outlet 50 of an external water source, such as municipal tap water shown in fig. 1, raw water flowing out of the external water source firstly flows into the front composite filter element 11 from a water inlet of the front composite filter element 11 through the water inlet pipeline 10, the front composite filter element 11 filters large particle impurities and some colored impurities in water and then outputs the water from a water outlet of the front composite filter element 11, so as to prevent the impurities in water from damaging devices such as the rear water inlet valve 12, the booster pump 13 and the reverse osmosis filter element 20, and thus effectively prolong the service life of the reverse osmosis water purification system.
In the present disclosure, in order to control the magnitude of the water flow and to control the operation of the reverse osmosis filter 20 in cooperation with the booster pump 13, a water inlet valve 12 is generally disposed on the water inlet pipeline 10, and the water inlet valve 12 may be a solenoid valve.

In one possible embodiment, the pressure detector 42 may be a high-pressure switch.
In the present disclosure, when pure water in the pressure tank 43 is stored to a preset threshold value, and the pressure in the pressure tank reaches a specified upper limit pressure value, the high-pressure switch will open the conductive loop, and the control device finds that the conductive loop is disconnected, and then controls the booster pump 13 and the water inlet valve 12 to be closed, so as to stop water production; when a user opens the faucet to start water use, the pressure of the pressure tank 43 is reduced, the high-pressure switch is automatically reset to a closed state, and the control device finds that the conductive loop is conducted to control the booster pump 13 and the water inlet valve 12 to be opened, so that raw water starts to make water through the pre-composite filter element 11 and the reverse osmosis filter element 20, and pure water stored in the pressure tank 43 and pure water made by the reverse osmosis filter element 20 simultaneously flow to the outlet of the pure water pipeline.

Here, the smaller the aperture of the water passing hole of the waste water valve is, the lower the flow rate of the waste water is, the specific size of the water passing hole needs to be selected according to the water purifying capacity of the reverse osmosis filter element 20, and when the water purifying capacity of the reverse osmosis filter element 20 is higher, the smaller the aperture of the water passing hole can be set. The waste water valve can be a normally closed type direct-acting electromagnetic valve, when the waste water valve is used at ordinary times, a valve port of the waste water valve is kept in a closed state, and waste water filtered by the reverse osmosis filter element 20 flows to the outlet 301 of the waste water pipeline 30 through the water through hole.
