Embodiment 1
As shown in Figure 1, the system includes gas storage unit 1, liquid storage unit 2, pressure the present invention provides a kind of gas storage system
Detection unit and control unit, liquid storage unit 2 are connected to by liquid supply pipe 3 with gas storage unit 1, and liquid supply pipe 3 is equipped with 4 He of booster pump
The top of supplying valve 5, gas storage unit 1 is connected to air supply pipe 6, and air supply pipe 6 is equipped with pressure sensing cell, booster pump 4, supplying valve
5 and pressure sensing cell be electrically connected with control unit.
Before use, enough liquid working substances need to be filled in liquid storage unit 2, wherein the liquid working substance can not preferably press
The liquid working substance of contracting, and the gas in gas storage unit 1 cannot be dissolved in the liquid working substance.For example, the gas in gas storage unit 1 is
When air, which can be used water.In addition, also need to set in a control unit according to actual needs the first setting pressure and
Second setting pressure, wherein the first setting pressure and the second setting pressure are all larger than predetermined supply gas pressure, and the first setting pressure
Less than the second setting pressure.
When deflation: the supply gas pressure in air supply pipe 6 can be detected by pressure sensing cell first, when supply gas pressure is less than the
When one setting pressure, supplying valve 5 is opened, and start booster pump 4 simultaneously, so that the liquid working substance in liquid storage unit 2 will be continuous
It is drawn into gas storage unit 1, the pressure of residual gas is just as liquid working substance is increasing in gas storage unit 1, in gas storage unit 1
Can constantly it increase, and then the supply gas pressure in air supply pipe 6 can also increase with it, when supply gas pressure is greater than the second setting pressure,
It can be turned off supplying valve 5 and booster pump 4.As a result, in entire deflation course, supply gas pressure is consistently greater than the first setting pressure,
That is supply gas pressure is not less than predetermined supply gas pressure always, so that the volume for not only significantly improving gas storage unit 1 utilizes
Rate, the stability that ensure that supply gas pressure, and also save the storage space of gas storage unit 1.In addition, due to booster pump 4
Efficiency is higher than the efficiency of gas compressor, therefore is greatly improved efficiency, energy saving by using booster pump 4.
Preferably, gas storage unit 1 is horizontal pressure vessel, and air supply pipe 6 is connected to the side of horizontal pressure vessel, liquid supply pipe
3 are connected to the bottom of horizontal pressure vessel.Enter gas supply with air-flow the advantages of this arrangement are as follows not only can avoid liquid working substance
Pipe 6, but also the power consumption of booster pump 4 can be reduced, it is energy saving.
Further, which further includes the liquid barrier 9 being arranged in horizontal pressure vessel, the first end position of liquid barrier 9
Extend in the lower section of air supply pipe 6, second end towards the top surface of horizontal pressure vessel, the second end and horizontal pressure vessel of liquid barrier 9
Top surface between there is gas passage, that is to say, that the edge of the edge of the first end of liquid barrier 9 and two sides is and Horizontal pressure
The inner wall of container connects, and has certain distance between the edge of the second end of liquid barrier 9 and the top surface of horizontal pressure vessel, that is, keeps off
The edge of the second end of liquid plate 9 and the top surface of horizontal pressure vessel, which are enclosed, to be set to form a gas passage.The benefit being arranged in this way exists

When the height of tracheae 6 is identical, the liquid working substance in liquid storage unit 2 can be still pumped into gas storage unit 1 by booster pump 4, to guarantee gas storage
The supply gas pressure of residual gas in unit 1；On the other hand, when gas flows into air supply pipe 6 by gas passage, it is mingled in air-flow
Liquid working substance and after liquid barrier 9 collides, can be flowed down along liquid barrier 9, and then liquid working substance can be further avoided with gas
Stream enters air supply pipe 6.
Further, the cross sectional shape of liquid barrier 9 is L-type.It should be noted that the shape of liquid barrier 9 can also be one end
Has plectane jaggy, plectane has top surface of the one end jaggy towards horizontal pressure vessel, and plectane is located at 6 lower section of air supply pipe
One end tilts upwards towards having one end jaggy.
Preferably, the second end of liquid barrier 9 is equipped with the second liquid level detection unit, and the second liquid level detection unit and control are single
Member electrical connection.When the liquid level of liquid working substance in liquid storage unit 2 is located at the second end of liquid barrier 9, i.e., when the liquid in liquid storage unit 2
When position height value is greater than the second setting liquid level, the liquid level height value that the second liquid level detection unit just will acquire is sent to control
Unit, and then control unit just can control supplying valve 5 and booster pump 4 to close, flow into air supply pipe 6 to avoid liquid working substance.
Preferably, which further includes return pipe 7 and the first liquid level detection unit, the outlet and liquid storage unit 2 of return pipe 7
Connection, import are connected to the bottom of gas storage unit 1, and return pipe 7 is equipped with return valve 8, and the bottom of gas storage unit 1 is inserted with first
Liquid level detection unit, return valve 8 and the first liquid level detection unit are electrically connected with control unit.When inflating as a result, reflux is opened
Valve 8, and booster pump 4 and supplying valve 5 is kept to close, when the liquid level of the liquid working substance in gas storage unit 1 drops to the inspection of the first liquid level
Survey unit where height when, i.e., when the liquid level in liquid storage unit 2 less than first setting liquid level when, gas storage unit 1
In liquid working substance drain substantially, the liquid level height value of acquisition is just sent to control unit by the first liquid level detection unit, in turn
Control unit just can control return valve 8 to close.
It is highly preferred that further include connecting tube 10, one end of connecting tube 10 respectively with the import of return pipe 7 and liquid supply pipe 3
Outlet, the other end are connected to the bottom of gas storage unit 1, to save pipeline and then save the cost.
It should be noted that in addition to can be by setting return pipe 7 come other than realizing draining, it can also be by by booster pump
4 are set as bidirectional booster pump to realize.
