Before use, the device is placed in a required place, an on-off valve is externally connected to a first liquid outlet pipe 2 and connected with external equipment, the on-off valve is closed, a cylinder 8 is connected with a first liquid inlet pipe 4 through a first bolt fastener 10, then the refrigerant is led in from a liquid inlet of a second liquid inlet pipe 12, so that the device can reach working running conditions, the device can be divided into three cases for use according to different use requirements of main work, and in addition, the initial state of the device is shown in fig. 1;
Case one: when the main tank 1 is required to be filled with the refrigerant, in the initial state of the device, the second bolt fastener 23 is removed, the third fixing plate 24 is moved downwards to a preset position, then the second bolt fastener 23 is assembled, then the refrigerant is introduced from the liquid inlet of the second liquid inlet pipe 12, the opening and closing plate 17 is in an opening state under the action of self gravity, the refrigerant flows into the cylinder 8 from the liquid outlet of the second liquid inlet pipe 12, then flows into the main tank 1 through the second liquid outlet pipe 9 and the first liquid inlet pipe 4, the floating ball push rod 27 gradually moves upwards under the action of the refrigerant until the floating ball push rod is stopped to move upwards by the second slide block 26, the range of upward movement of the floating ball push rod 27 is reduced due to the fact that the first connecting rod 25 carries the second slide block 26 to move downwards integrally, when the liquid level of the refrigerant contacts the floating plate 44, the refrigerant acts on the floating plate 44 to move upwards, the floating plate 44 moves upwards and acts on the ejector rod 45 to synchronously move upwards, the ejector rod 45 acts on the triangular block 40, so that the triangular block 40 moves towards the middle of the inner side of the square block 14 with the plugging plate 39, when the top of the refrigerant acts on the floating plate 44 and the inner side top surface of the telescopic pipe 38 are attached, the plugging plate 39 cuts off the liquid inlet pipe II 12, so that the refrigerant is stopped from being introduced, and as the main box 1 is less than the barrel 8 by one height of the floating plate 44, the liquid level of the refrigerant in the barrel 8 is at the bottom of the floating plate 44, so that the liquid level in the main box 1 reaches the inner side top surface of the main box 1, namely the refrigerant in the main box 1 is filled at the moment;
and a second case: when the refrigerant is not fully filled in the main tank body 1 for liquid level control, in an initial state, according to the requirement of liquid level height, the motor II 30 is started, the slide III 31 moves upwards towards the direction of the motor II 30 outside the screw rod II 29, the slide III 31 acts on the liquid inlet pipe II 12 through the connecting rod II 32 and the connecting plate 33 to synchronously move upwards, the first storage rack 18 is fixedly connected with the fixed ring 13, the second liquid inlet pipe 12 moves synchronously with the first storage rack 18, the connecting rod II 25 moves upwards with the slide II 26, the slide II 26 moves upwards to a certain height and is limited by the top of the floating ball push rod 27, the motor II 30 is synchronously closed after the liquid outlet of the liquid inlet pipe II 12 reaches the height of a preset scale on the scale table on the second observation window 11, and then the refrigerant is introduced as in the first case, the floating ball push rod 27 gradually moves upwards under the action of the refrigerant until the floating ball push rod 27 moves upwards to push the opening and closing plate 17 to a closed state, at this time, the liquid outlet of the liquid inlet pipe II 12 is blocked by the opening and closing plate 17, at this time, the refrigerant in the main tank 1 reaches a preset liquid level, in addition, when the refrigerant in the main tank 1 needs a high liquid level state, the motor II 30 acts on the sliding block III 31 to move upwards until the top of the sliding block III 31 is completely attached to the inner top surface of the second storage rack 28 and then stops, the sliding block III 31 moves upwards to move with the base plate 35, the base plate 35 moves upwards to act on the telescopic rod 36 to shrink, the telescopic rod 36 acts on the protruding block 37 to further move the telescopic pipe 38 upwards under the action of the continuous upward movement of the sliding block III 31 after the telescopic rod 36 is completely shrunk, the telescopic pipe 38 extends to the maximum value when the top of the sliding block III 31 is completely attached to the inner top surface of the second storage rack 28, the telescopic pipe 38 can not only be used when being extended to the maximum value, but also the telescopic pipe 38 is used for compensating the defect caused by the self height of the floating ball push rod 27, so that the situation that the inside of the main box body 1 cannot be filled with the refrigerant or the refrigerant cannot reach a high liquid level state is avoided, and the liquid level inside the main box body 1 can meet the requirement of adjusting and controlling from a low liquid level to a high liquid level;
And a third case: when the device is not in use and the liquid inlet pipe II 12 is required to be closed, the first motor 20 is started to act on the first screw rod 19 to rotate, so that the first slider 21 moves upwards through the second fixed plate 22, and the third fixed plate 24 is connected with the second fixed plate 22 through the second bolt fastener 23, so that the first connecting rod 25 moves upwards with the second slider 26 synchronously, and when the first slider 21 moves upwards to a preset position, the second slider 26 pushes the opening and closing plate 17 upwards with the floating ball push rod 27 to reach a closed state, so that the closing operation of the liquid inlet pipe II 12 is completed.
