連通して構成するのである。The drawing shows an embodiment of the liquid injection/discharge device according to the present invention, in which 1 is a first changeover valve, and the first changeover valve 1 has one end connected to a liquid discharge path 3 through a first passage 2. It communicates with the tank 4 and the other end communicates with a forced air discharge device 6 via a second passage 5. The forced air discharge device 6 includes an air discharge passage 7 and a second switching valve 9 via a third passage 8. The other side of the second switching valve 9 is connected to an air compressor 11 via a fourth passage 10.
Further, the first passage 2 and the fourth passage 10 are configured to communicate with each other through a fifth passage 13 with a third switching valve 12 interposed therebetween.

。When the first switching valve 1 and the second switching valve 9 are opened and the third switching valve 12 is closed, the compressed air from the compressor 11 is transferred to the fourth passage 10, the second switching valve 9, and the third passage 8. ,
The air in the liquid tank 4 is suctioned through the forced air evacuation device 6 and the air evacuation path 7 in order to the outside world.
The liquid is discharged to the outside world through the first switching valve 1, the second passage 5, the forced air discharge device 6, and the air discharge passage 7, and as the pressure inside the liquid tank 4 decreases, liquid is injected from the liquid inlet/outlet passage 3.

は液体出入路３を経て排出されるのである。In addition, when discharging liquid from the liquid tank 4, the pressure is adjusted appropriately and the third switching valve 12 is opened, while when the first switching valve 1 and the second switching valve 9 are closed, the compressed air from the compressor 11 is discharged. , the fourth passage 10, the fifth passage 13 with the third switching valve 12 interposed therebetween, and the first passage 2. It is then excreted.

Second passage 5, forced air exhaust device section 6 and air exhaust path 7
are communicated with the outside world by sequentially valving them, and the pressure becomes the same as atmospheric pressure.
The liquid in the liquid tank 4 does not move, i.e.
The liquid injection/discharge operation is stopped.

ることができるのである。Since the present invention has the above-mentioned configuration, when the first switching valve and the second switching valve are opened and air is sent from the air compressor, the air is discharged to the outside world through the forced air discharge device. The air inside the liquid tank is sucked out,
Therefore, when liquid is injected from the liquid inlet/outlet passage and the second switching valve is closed, the liquid tank and the outside world are communicated with each other via the first switching valve, and the pressure is the same. The liquid injection operation is stopped, then the first switching valve and the second switching valve are closed, and the third switching valve is opened, and the compressed air from the compressor enters the liquid tank, so that the pressure of the air causes the liquid to become liquid. The liquid is discharged from the liquid tank via the inlet/outlet passage, and at this time, when the first switching valve is opened and the third switching valve is closed, the pressure inside the liquid tank becomes the same as that of the outside world via the first switching valve, as described above. Therefore, the liquid discharge operation can be stopped.
すなわち、本考案は簡単な構造によって圧搾空気の制御
によって液体タンクの液体注入・排出操作を自由に行う
ことができ、きわめて実用的である。That is, the present invention has a simple structure and allows the liquid to be freely injected and discharged from the liquid tank by controlling compressed air, making it extremely practical.
