Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1-2 is referred to, the utility model provides a kind of technical scheme：A kind of high-precision air-compression type level pressure unit, including
Base 1, the upper surface of base 1 are provided with pressure expansion tank 2, power supply 3 and booster pump 4, and the top of pressure expansion tank 2 is provided with and put
Gas port 11, the middle part of gas vent 11 are provided with safety valve 12, when the pressure in tank exceedes the restriction pressure value in safety valve 12
When, safety valve 12 will be actuated for deflating.The inner chamber of pressure expansion tank 2 is provided with pressure sensor 5 and liquid level sensor 6,
Pressure value and level value can be monitored constantly.The left side bottom of pressure expansion tank 2 is provided with water-supply-pipe 7, and the water-supply-pipe 7 is from the right side
The 4th valve 72, the second valve 74 and automatic control water compensating valve 42 are sequentially provided with to a left side, the middle part of water-supply-pipe 7 is provided with blow-off pipe 71,
Between the 4th valve 72 and the second valve 74, the 4th valve 72 is used to turn prevention pressure expansion manually the blow-off pipe 71
Water outflow in tank 2.The left end of water-supply-pipe 7 is provided with booster pump 4, and booster pump 4 is used to increase hydraulic pressure.The left end of booster pump 4
Provided with water inlet pipe 41, the middle part of blow-off pipe 71 is provided with the first valve 73, when needing blowdown, the first valve 73 of control is beaten
Open, the second valve 74 is closed, and the sewage in pipe is discharged.The top of power supply 3 is provided with air compressor machine 8, and the left end of air compressor machine 8 is set
After thering is appendix 81, air compressor machine 8 to compress air in input pressure expansion drum 2, because air compression ratio is higher, compression essence
Degree is easier to control so that is easier to control when the air after compression is input in pressure expansion tank 2.The middle part of appendix 81
Provided with the 3rd valve 82, the left end of appendix 81 connects with the right side upper end of pressure expansion tank 2.First valve 73, second
Valve 74, the 3rd valve 82 are electromagnetic valve, and the 4th valve 72 is manually-operated gate.The air compressor machine 8, booster pump 4, liquid
