Detailed description of the invention
Referring to accompanying drawing.Five valves 5 of the present embodiment include valve casing 51, spool 52, spring 53 and sealing member 54；Described valve casing 51 is stagewise cylindrical structural, and top and upper cover 55 are threaded connection, and valve casing 51 cross section is " convex " font, and top is little head end, and bottom is stub end；Described valve casing 51 lower end is threaded connection lower cover 56；Described spool 52 is placed in valve casing 51, and spool 52 is syllogic column structure, and epimere is spring retention posts 521, and spool stage casing 522 is positioned at the little head end of valve casing 51, and spool hypomere 523 is positioned at the stub end of valve casing 51；Described spool stage casing 522 and spool lower end 523 excircle are provided with annular seal groove, and sealing member 54 is placed in seal groove；Being provided with through hole in the middle of described upper cover 55, the spring retention posts 521 of spool is through the through hole of upper cover 55, and described spring 53 is placed in above spool 52, and one end is enclosed within spring retention posts 521, and the other end is against on upper cover 55.There is space between outer wall and the inwall of valve casing 51 of described spool 52, the sealing member 54 on spool 51 excircle is close to the inwall of valve casing, then the space between spool 51 and valve casing 52 is runner, and sealing member 54 is used for intercepting runner.
The excircle of five valve valve casings 51 of the present embodiment has five ports, respectively waste water inlet 511, waste water district import and export 512, purified water inlet 513, pure water outlet 514 and discharge outlet 515；The waste water end of described RO filter element 2 connects waste water inlet 511, and waste water district imports and exports the waste water district 33 of 512 Bonding pressure buckets, the pure water district 32 of purified water inlet 513 Bonding pressure bucket, pure water outlet 514 connection depotition cock 7.In five ports of described five valves 5, waste water inlet 511, discharge outlet 515, waste water district import and export 512 outsides being positioned at the little head end of valve casing 51, waste water inlet 511, discharge outlet 515 are positioned at side, waste water district imports and exports 512 and is positioned at opposite side, and waste water district imports and exports 512 position height between waste water inlet 511, discharge outlet 515 position height；Described pure water outlet 514 and purified water inlet 513 are positioned at the both sides of valve casing 51 stub end.
Pure water hydraulic pressure in described pure water district 32 is high, when pure water hydraulic pressure between pure water outlet 514 and purified water inlet 513 is higher than spring 53 elastic force, spool 52 moves, making described sealing member 54 be positioned at waste water district to import and export above in the of 512 and below discharge outlet 515, waste water inlet 511 and waste water district import and export at least has a circle sealing member between 512；Waste water district in five valves 5 imports and exports 512 and turns on discharge outlet 515, and in waste water district 33, waste water is discharged；When the pure water hydraulic pressure in pure water district 32 is low, when pure water hydraulic pressure bottom spool 52 is lower than spring 53 elastic force, spool 52 moves down, making described sealing member 54 be positioned at above waste water inlet 511 and waste water district imports and exports below 512, discharge outlet 515 and waste water district import and export at least has a circle sealing member 54 between 512；Waste water inlet 511 in five valves and waste water district import and export 512 conductings, and in waste water district 33, waste water increases.
The water purifier of five valve 5 work of the present embodiment includes preposition filter element 1, RO filter element 2 and pressure pot 3, pressure pot is divided into pure water district 32 and waste water district 33 by partition 31 by described pressure pot 3, partition 31 is flexible structure, it is possible to is changed by the pressure in pure water district, both sides 32 and waste water district 33 and moves back and forth；The pure water district 32 by the first non-return valve 4 Bonding pressure bucket, the water side of described RO filter element 2, the waste water end of described RO filter element 2 is divided into two-way, and a road connects waste water ratio and controls valve 8, and five valves 5 of separately leading up to are connected to the waste water district 33 of pressure pot.The pure water district 32 of described pressure pot connects five valves 5 by the second non-return valve 6；Described five valves 5 control the capacity of wastewater in waste water district 33 by the pure water hydraulic pressure in pure water district 32.It is the valve controlling discharge of wastewater that described waste water ratio controls valve 8.
During the present embodiment work, tap water first passes through preposition filter element 1 and tentatively filters, water after preliminary filtration enters RO filter element 2, the pure water that RO filter element 2 produces enters the pure water district 32 of pressure pot 3 by the first non-return valve 4, pure water enters the partition 31 during pure water district 32 in meeting squeeze pressure bucket 3 so that the full pure water of system in pressure pot 3.
When depotition cock 7 is opened, the pressure in pure water district 32 diminishes, pure water hydraulic pressure is lower than spring 53 elastic force, the spool 52 of five valves 5 moves down, make described sealing member 54 be positioned at above waste water inlet 511 and waste water district imports and exports below 512, discharge outlet 515 and waste water district import and export at least has a circle sealing member 54 between 512, waste water inlet 511 and waste water district import and export and are absent from sealing member 54 between 512, the waste water inlet 511 of five valves is imported and exported 512 with waste water district and is connected, tap water enters the waste water district 33 of pressure pot by the waste water end of RO filter element 2, by the pressure in waste water district 33, the pure water in pure water district 32 is extruded pressure pot 3, make depotition cock 7 water outlet.
When depotition cock 7 is closed, five valve pure water outlets 514 will be delivered to the wastewater pressure of five valves 5 with purified water inlet 513 by pressure pot waste water district 33, five valve cores 52 are moved upward, make described sealing member 54 be positioned at waste water district to import and export above in the of 512 and below discharge outlet 515, waste water inlet 511 and waste water district import and export at least has a circle sealing member 54 between 512, waste water district imports and exports and is absent from sealing member 54 between 512 and discharge outlet 515, so that the waste water district 33 of the waste water inlet 511 of five valves 5 and pressure pot cuts off, waste water in waste water district 33 imports and exports 512 entrance by the waste water district of five valves 5, via the interstitial flow of spool 52 outer wall and valve casing 51 inwall to discharge outlet 515, discharge eventually through discharge outlet 515；Owing to the purified water inlet 513 of five valves 5 connects the effect of the second non-return valve 6, it is ensured that pressure does not reduce, it is achieved not moving of spool 52；Draining outward when five Mian Fa waste water districts import and export 512 connect with discharge outlet 515, in pressure pot 3, pressure is 0, and pure water outlet 514 pressure is also that 0, RO filter element 2 carries out controlling the water circulation under the effect of tap water pressure difference；When pure water is full of in pressure pot 3, reaching tap water pressure, RO filter element 2 stops controlling the water circulation, waits that depotition cock 7 is opened next time.
