うにした給液装置を提供するにある。 Furthermore, Japanese Patent Publication No. 11384/1984 describes an article suction and transfer device in which when the extension operation of the main cylinder reaches the end point and the operating pressure increases, the auxiliary cylinder is extended and the auxiliary cylinder is actuated to adsorb the article. The technique is shown. However, even if this known technology is applied to the liquid supply device and an alarm is connected to the switching valve 8, the water head pressure of the probe cannot be used, and both pressure chambers of the sub-cylinder have approximately equal pressure. Since the air pressure is applied, the extension operation is difficult. SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a liquid supply device in which an overflow prevention valve can be reliably closed even when a large-capacity alarm is used.

スとして絞り効果を変え得るようにしてもよい。 The control valve 10 is a spring-offset pneumatically operated two-position switching valve, and has an outflow port 26 communicating with the alarm 11, an inflow port 21 connected to the airline 13, and an atmosphere vent hole 27 open to the atmosphere. are communicated in parallel via passages 28, 29 and 30. A diaphragm chamber 31 and a control valve 1 are located in the middle of these passages 28, 29, and 30, respectively.
A diaphragm chamber 32 is formed as a drive unit of the 0, and upper chambers 31a, 32a and lower chambers 31b, 32b are defined by diaphragms 33, 34 stretched over these diaphragm chambers 31, 32, respectively. has been done. In the center of these diaphragms 33, 34 are passages 28, 29, 30.
The valves 35 and 36 are connected by a connecting rod 37, and when the valve 35 is opened, the valve 36 is closed.
When the valve 36 is closed, the valve 36 is opened. Such a control valve 10 is integrally connected to the air cylinder 9 via a partition 38, and the pressure chamber 20 of the air cylinder 9 and the lower chamber 32b of the diaphragm 34 below the control valve 10 are connected to the orifice 39. The air communicated through the air line 12 and led to the pressure chamber 20 is led to the lower chamber 32b through the orifice 39. This control valve 10 is normally operated by a spring 40.
The air pressure from the pressure chamber 20 is gradually applied to the diaphragm 34 via the orifice 39.
When the pressure in the lower chamber 32b becomes equal to the pressure in the upper diaphragm chamber 31, that is, the pilot pressure, the switch is made to the (b) position, and the air pressure in the airline 13 is applied to the alarm 11 via the passages 29 and 28.

Then, the switching valve 16
Switches from position (a) to position (b). Therefore, air source 1
5 through air lines 12 and 13 to the pressure chamber 20 of the air cylinder 9 and the control valve 1.
0 is supplied to the diaphragm chamber 31 above. As a result, the air cylinder 9 releases the valve opening latch of the overflow prevention valve 7, which has been operated to the expansion side, and closes the valve.
On the other hand, the pressurized air in the pressure chamber is throttled by the orifice 39 and gradually guided to the lower chamber 32b of the diaphragm 34. Then, the pressure in the lower chamber 32b becomes
When the pressure exceeds the pressure for switching 0, that is, when the air cylinder 9 is activated and the overflow valve 7 is closed, the control valve 10 is switched from the (a) position to the (b) position, and the pressurized air in the airline 13 is Passage 29,2
8 to the alarm 11. In this way, the alarm 11 notifies the tank truck driver that the overflow valve 7 has been reliably closed.
