Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
In figure 1, a pipeline I; 2. a valve I; 3. a cylinder body; 4. a free piston; 5. a conduit III; 6. a valve III; 7. a valve IV; 8. a conduit IV; 9. a pipe II; 10. and a valve II.
The specific implementation mode is as follows:
as shown in fig. 1: the high-low pressure automatic circulation device comprises a free piston, wherein the free piston is arranged in a cylinder body; the two ends of the cylinder body are closed and are provided with pipelines I, II, III and IV; a high-pressure medium is arranged in the pipeline I, and a valve I is arranged on the pipeline; the valve I controls the motion state of a medium in the pipeline I; a secondary high-pressure medium is arranged in the pipeline II, and a valve II is arranged on the pipeline; the valve II controls the motion state of a medium in the pipeline II; a secondary low-pressure medium is arranged in the pipeline III, and a valve III is arranged on the pipeline; the valve III controls the motion state of a medium in the pipeline III; a low-pressure medium is arranged in the pipeline IV, and a valve IV is arranged on the pipeline; the valve IV controls the motion state of the medium in the pipeline IV.
Further, the cylinder block is divided by the free piston into two chambers a and B, the chamber B being the input side of the circulation system and the chamber a being the output side of the circulation system. The medium is decompressed to a low-pressure state after passing through the cavity B and enters the system, the medium output by the system enters the cavity A after being pressurized, and the medium is pressurized to a sub-high-pressure state and enters the booster pump for recirculation.
Furthermore, the valves I and IV are mutually exclusive, namely, the valves I and IV cannot be opened at the same time, so as to avoid damaging the system; the valve II and the valve III are mutually exclusive, namely, can not be opened at the same time, so as to avoid damaging the system.
