Two-way sequentially enters the first valve plate 3 and the second valve plate 4.
The gases at high pressure flowed out from the first valve plate 3, which remain unchanged, is divided to two-way to sequentially enter the first two five-way electromagnetic valves 5 and second
Two five-way electromagnetic valves 6, now enter the first 2/2-way Pneumatic valve from the gases at high pressure that the first two five-way electromagnetic valves 5 flow out
After 9 Pneumatic reversal valve mouthful, the first 2/2-way Pneumatic valve 9 can be made to be in transposition conducting state；From the second two five energization magnetic
The gases at high pressure that valve 6 flows out enter after the Pneumatic reversal valve mouthful of the second 2/2-way Pneumatic valve 10, can make the second 2/2-way gas
Control valve 10 and be in transposition cut-off state, now, the liquid that oil sources 14 is discharged enters the first core through the first 2/2-way Pneumatic valve 9
In displacement pump 1, the first core flooding pump 1 realizes imbibition.
Meanwhile, from the second valve plate 4 flow out gases at high pressure remain unchanged be divided to two-way sequentially enter the 3rd two five-way electromagnetic valve 7 and
4th two five-way electromagnetic valve 8, the gases at high pressure flowed out from the 3rd two five-way electromagnetic valve 7 enter the 3rd 2/2-way Pneumatic valve
After 11 Pneumatic reversal valve mouthful, the 3rd 2/2-way Pneumatic valve 11 can be made to be in transposition cut-off state；From the 4th two five energization
The gases at high pressure that magnet valve 8 flows out enter after the Pneumatic reversal valve mouthful of the 4th 2/2-way Pneumatic valve 12, can make the 4th 2/2-way
Pneumatic valve 12 is in transposition conducting state, now, and the liquid of the second core flooding pump 2 discharge can be through the 4th 2/2-way Pneumatic valve
12 export to executive component 15.
Above-mentioned steps only need to be alternately performed, you can realize the friendship between the first core flooding pump 1 and the second core flooding pump 2
For liquid sucking-discharging process, and then the output requirement of high-precision high voltage power is met, control process is simple and time saving and energy saving.
Scheme in embodiment and the scope of patent protection for being not used to the limitation present invention, it is all without departing from carried out by the present invention etc.
Effect is implemented or changed, and is both contained in the scope of the claims of this case.
