Principle of work of the present invention: control valve of the present invention is a combination valve, when it normally makes water, high-voltage switch gear is opened, water purification enters in the water-purifying cavity, the water-purifying cavity volume becomes the smaller volume that forces pressure chamber greatly, hydraulic pressure increase in the pressure chamber makes in the flow direction combination valve, hydraulic pressure in pressure chamber continues to increase, the hydraulic pressure in the pressure limiting chamber of combination valve also continues to increase, the pressure limiting assembly seals the water shutoff mouth between dense hydraulic pressure chamber and the pressure limiting chamber when being increased to certain limit, after the water shutoff mouth is sealed, the hydraulic pressure that enters in the combination valve from pressure chamber further increases, thereby extruding pressure release assembly seals pressure release and opens, and the water in the pressure chamber then can enter main water supply tube road before the topping-up pump by discharge opening two, stores enough water purification and be pressurized to high-voltage switch gear in water-purifying cavity and close, shut down; Meanwhile, enter the dense hydraulic pressure chamber of combination valve from the dense water of reverse osmosis filter group combination of flow valve, and the sealing of the water shutoff mouth between dense hydraulic pressure chamber and pressure limiting chamber, therefore dense water rests in the dense hydraulic pressure chamber, increase along with dense water in the dense hydraulic pressure chamber, dense water hydraulic pressure overcomes the pressurize hydraulic pressure of pressurize assembly in it, thereby makes the pressurize assembly no longer seal the pressurize mouth of a river, and dense water like this then can be discharged through choked flow mouth two and through the pressurize mouth of a river.When using water purification, hydraulic pressure in the pressure chamber is discharged along with water purifying and is reduced, the hydraulic pressure in the interior pressure limiting chamber of combination valve this moment also reduces, cause the pressure limiting assembly to open the water shutoff mouth, pressure limiting chamber and dense hydraulic pressure chamber are connected, the current that the concentrated water spout of reverse osmosis filter group is discharged enter in the pressure chamber by combination valve, thereby the extrusion film bag is discharged the water purification in the water-purifying cavity, and reverse osmosis filter group is finished the flushing to himself automatically in the process of draining.
When control valve of the present invention is electrically-controlled valve, it also is provided with the switch by flow or the start and stop of hydraulic pressure control electrically-controlled valve, therefore, it controls system water and towards discharge water except adopting above-mentioned similar principle by high-voltage switch gear, can also be when clear water faucet be opened, the induction to flow or hydraulic pressure comes the present invention is carried out control corresponding through switch.
The present invention compared with prior art has the following advantages and beneficial effect: the water filling in pressure chamber in the water purifying use of (1) reverse osmosis filter of the present invention group, finished flushing synchronously to self, saved scouring electromagnetic valve, in the water-purifying cavity during water filling, current in the pressure chamber can enter in the main water supply tube road before the topping-up pump by discharge opening, backflow is used to produce water purification, economizes on resources.
(2) the present invention is provided with the pressurize assembly, and the switching motion hydraulic pressure value of high-voltage switch gear is less than the breakdown action hydraulic pressure value of pressurize assembly, when the water-in two of combination valve and the passage bad sealing between the water outlet two are close, pressurize assembly sealing choked flow mouth two, current in the pressure limiting chamber can not discharged through choked flow mouth two, thereby avoided effectively that hydraulic pressure reduces in the pressure chamber, bag film expands and causes the hydraulic pressure in the water-purifying cavity to continue to reduce, and prevents that high-voltage switch gear from starting repeatedly and close.
