Intermediate be equipped with of set divides water jacket, and spool right end sliding surface both ends are male conical structure, and the inner end of two valve pockets is and male conical
Structure is coincide corresponding recessed pyramidal structure.
In above-mentioned technical proposal: the right compression conduit C leads to position in energy switching valve at valve core upper sleeve shock mount, mutually
Siphunculus road 8 is connected to the position for dividing water jacket in energy switching valve.
Compared with prior art, the present invention having following advantageous effect: since the present invention is in compression piston and reverse osmosis group
Energy switching valve is set between part, constitutes one group of optimum composition method using three compression pistons in addition, can allow three compressions
The operation of piston energy alternate cycles, operational effect is best, in operational process, after piston body back and forth sucks seawater, through compressed pipe
Road B is pumped into reverse osmosis module by high-pressure osmosis desalting seawater, and 40% acquired fresh water is arranged by purification fresh water discharge pipe
Out, 60% seawater of tape remaining overbottom pressure enters energy switching valve by right compression conduit C again, and high pressure sea water will by pipeline A at this time
Amount conversion valve core is pushed into right end, and overbottom pressure seawater ALT-CH alternate channel is opened in energy switching valve, by the road having into compression piston
Rod cavity, cooperation crankshaft work done push piston body right lateral, and after overbottom pressure makes full use of, no pressure seawater can be with the drive of crankshaft by piston
Body is reversely pumped into intercommunication pipeline being discharged without pressure seawater discharge pipe through energy switching valve right end again, and thus alternate cycles operation reaches
To energy-saving effect, solve the problems, such as that energy waste existing in the prior art and production cost are excessively high, design science is advantageous to save
The promotion and popularization that can be lowered consumption with sea water desalination processing.

Specific embodiment
Fig. 1, shown in 2: there are three can be connected the reverse osmosis deaslination equipment for sea water desalination processing with power crankshaft side by side
The compression piston 1 for being built-in with piston body 2, the right end of three compression pistons 1 passes through right compression conduit A4 respectively and leads to three energy
Switching valve 3 sets right compression conduit B5 in the side of three right compression conduit A4 respectively and leads to reverse osmosis module 6, right in reverse osmosis module 6
End separately sets right compression conduit C7 and leads to respectively with 3 side of energy switching valve；Three energy switching valves 3 set mutual siphunculus in the other side respectively
Road 8 is connected to the rod chamber of three compression pistons 1；6 side of reverse osmosis module separately sets the discharge pipe 9 that desalinizes seawater；It is compressed at three
The right end of piston 1 separately sets the water inlet pipe 10 of inhalable seawater respectively, and three energy switching valves 3 are respectively equipped with without pressure seawater discharge pipe
12, the right compression conduit B5 and water inlet pipe 10 are respectively provided with check valve 11.Spool 13, the spool are equipped in energy switching valve 3
Spring 14 is cased at thin bar among 13,13 medial surface of spool is close in 14 one end of spring, and the other end is close in energy switching valve 3
The valve pocket 15 set, there are the space that spool 13 moves left and right between two valve pockets 15 in energy switching valve 3, among two valve pockets 15
Equipped with dividing water jacket 17,13 right end sliding surface both ends of spool are male conical structure, and the inner end of two valve pockets 15 is and male conical
