たことを特徴とする定量計量装置。[Scope of Claim for Utility Model Registration] A flowmeter 2 and an automatic opening/closing valve 3 are arranged in a pipe 1 through which the liquid to be measured flows, a preset counter 4 is attached to the flowmeter 2, and the automatic opening/closing valve 3 is provided with an opening/closing valve. The cylinder 5 is installed, and the valve 3 is automatically opened and closed by the signal from the preset counter 4.
In a quantitative measuring device that performs quantitative measurement of a liquid to be measured by opening and closing, an air switch 6 is attached to the preset counter 4, and the operating lever 7 of the air switch 6 is pressed according to the setting value of the preset counter 4 to release air. When the circuit is connected and the count value of the preset counter 4 reaches the set value, the operating lever 7 is returned to open the air circuit. A switching valve 10 is disposed between the switching valve 10, a start button 11 for pressing the pilot part 12, and an automatic return spring 13 are attached to the switching valve 10, and an air source 9 is connected to the first port 20 of the switching valve 10. The opening operation side 25 of the opening/closing cylinder 5 is connected to the second port 21, and the opening operation side 25 of the opening/closing cylinder 5 is connected to the third port 22.
The same closing operation side 26 is connected to the same, and the second
The air switch 6 is connected to the fifth port 23 which communicates immediately before the port 21, and the switching valve 1
6th port 24 communicating with the pilot section 12 of 0
A quantitative measuring device characterized in that an air switch 6 is connected to the air switch 6 via a small switching valve 8.
