Repel each other with the magnetic element 50 on the second commutation plug 52；
Four check-valves 70 are connected to the first water inlet 13, the first water outlet 14, the second water inlet 23 and the second water outlet
On 24；
Pressure pump 80, the water outlet of the pressure pump 80 are connected in parallel in two check-valves of the first water inlet 13 and the second water inlet 23
70；
Filter core 90, the one end of the filter core are equipped with fresh seawater entrance 91, and the other end is equipped with pure water outlet 92 and high pressure waste water
Outlet 93, which is connected in parallel in two check-valves 70 of the first water outlet 14 and the second water outlet 24, the height
Pressure wastewater outlet 93 is connected in parallel on the first waterwater entrance 44 and the second waterwater entrance 45.
When first used, the second water inlet 23 can be closed by successively opening the check-valves 70 at the first water inlet 13
Check-valves 70 at the check-valves 70 at place, and the first water inlet 13 of closure, opens the check-valves 70 at the second water inlet 23, makes
It obtains pressure pump 80 and promotes seawater in the first cylinder 10 from the first water inlet 13, or seawater is promoted second from the second water inlet 23
In cylinder 20, the air in the first cylinder 10 and in the second cylinder 20 is emptied, then again from the first water outlet 14 or the second
Water outlet 24 pushes in filter core 90, and filter core 90 filters clean pure water after the completion of filtering, through the discharge of pure water outlet 92, leads to
Cross high pressure wastewater outlet 93 be discharged high pressure waste water, high pressure waste water pass through respectively the first waterwater entrance 44 or the second waterwater entrance 45 into
Enter intracavitary to commutating.
Assuming that first piston 61 is resisted against at the first end cover 12 of the first cylinder 10, the first commutation plug 51, which is resisted against, to be adjoined
41 end of commutation chamber in adjacent first high pressure waste water area 15, the first drainage hole 47 is open, and the second drainage hole 48, which is blocked, to be filled in, the
One waterwater entrance 44, which is blocked, to be filled in, and the second waterwater entrance 45 is open, and second piston 62 is resisted against commutation 30 end of valve seat, this
When, the high pressure waste water in the second high pressure waste water area 25 has passed through the discharge of low pressure wastewater outlet 46, and the high pressure that filter core 90 generates is useless
Water has been injected into the first high pressure waste water area 15 and due to the opening of the first drainage hole 47, in the first high pressure waste water area 15
Wastewater pressure reduces, and becomes low pressure waste water（As shown in Figure 8）；At this point, since the first fresh seawater area 11 is in decompression state, the
One water inlet 13 is opened, and seawater is promoted the first fresh seawater area 11 of the first cylinder 10 by pressure pump 80 from the first water inlet 13
Interior, first piston 61 starts under the pressure of fresh seawater towards the movement of commutation 30 end of valve seat, will be in the first high pressure waste water area
Low pressure waste water is intracavitary to commutating through 47 force feed of the first drainage hole, is most discharged afterwards through low pressure wastewater outlet 46；At the same time, second
Piston 62 follows first piston 61 to link, and the fresh seawater pushed in the second fresh seawater area 21 is entered through the second water outlet 24
In filter core 90, filter core 90 filters clean pure water after the completion of filtering, through the discharge of pure water outlet 92, is exported by high pressure waste water
93 discharge high pressure waste waters, high pressure waste water is entered in commutation chamber 41 by the second open waterwater entrance 45, due to the chamber 41 that commutates
At this time with 25 connection of the second high pressure waste water area, high pressure waste water is injected into the second high pressure waste water area 25 by the chamber that commutates, and high pressure is useless
Water starts to be full of the second high pressure waste water area 25 and auxiliary pushing second piston 62, reinforces the promotion energy of second piston 62, reaches
Energy-efficient effect；As first piston 61 is close and is resisted against commutation 30 end of valve seat, in the effect of the magnetic element 50 to repel each other
Under, reversing piston is pushed under magneticaction, and the first commutation plug 51 is mobile towards 42 direction of the first stopper section in commutation chamber 41
And be resisted against in the first backstop 42, the second commutation plug 52 is resisted against 41 end of commutation chamber for adjoining the second high pressure waste water area 25,
At this point, the first waterwater entrance 44 is open, the second waterwater entrance, which is blocked, to be filled in, and the first drainage hole 47, which is blocked, to be filled in, the second draining
Through-hole 48 is open（As shown in Figure 7）.
As the second drainage hole 48 is open, the wastewater pressure in the second high pressure waste water area 25 is reduced, and becomes low pressure waste water,
At this point, the second fresh seawater area 21 is in decompression state, the second water inlet 23 is opened, and pressure pump 80 is by seawater from the second water inlet
23 promote in the second fresh seawater area 21 of the second cylinder 20, and second piston 62 starts under the pressure of fresh seawater towards commutation
30 end of valve seat is mobile, by the low pressure waste water in the second high pressure waste water area 25 through 48 force feed of the second drainage hole to commutation chamber 41
It is interior, most it is discharged afterwards through low pressure wastewater outlet 46；At the same time, first piston 61 follows second piston 62 to link, and push first is new
Fresh seawater in fresh sea-water area 11 enters in filter core 90 through the first water outlet 14, and filter core 90 is after the completion of filtering, by pure
Clean pure water is filtered in the discharge of water out 92, and by 93 discharge high pressure waste water of high pressure waste water outlet, high pressure waste water passes through open
First waterwater entrance 44 enters in commutation chamber 41, and since commutation chamber 41 is at this time with 15 connection of the first high pressure waste water area, high pressure is useless
Water is injected into the first high pressure waste water area 15 by the chamber 41 that commutates, and high pressure waste water starts to be full of the first high pressure waste water area 15 and assist
First piston 61 is pushed, reinforces the promotion energy of first piston 61, reaches energy-efficient effect；As second piston 62 is close and supports
It is against commutation 30 end of valve seat, under the action of magnetic element 50 repelled each other, reversing piston is pushed under magneticaction, and second
