Abstract
The present invention allows measurement of a precise amount of gas by preventing sudden flow rate fluctuations of gas. A gas supply system 1a for a mixing-discharging apparatus 90 to mix gas and paste material includes a regulator 2 adapted to control pressure of gas supplied to the mixing-discharging apparatus, a flow meter 3 adapted to measure flow rate of the gas, a gas storage portion 4 adapted to store the gas, and a valve 5 adapted to open and close a gas introduction path 11 to the mixing-discharging apparatus 90. The flow meter 3 is placed in front of the gas storage portion 4 and behind the regulator 2 with respect to a flow of the gas.
Claims26
A gas supply system for a mixing-discharging apparatus equipped with a piston pump having a predetermined volume to mix gas and paste material, the gas supply system comprising:
- a regulator adapted to control pressure of gas supplied from a gas supply source;
- a flow meter adapted to measure a flow rate of the gas;
- a gas storage portion adapted to store the gas;
- and
- a valve adapted to open and close a gas introduction path to the mixing-discharging apparatus,
- wherein in the gas storage portion, a volume ratio of the gas storage portion to the predetermined volume of the piston pump is established between 4 and 100 such that sudden flow rate fluctuations in a flow path in which the flow meter is placed do not occur in a shorter amount of time than a sampling time of the flow meter when the valve is open and gas is supplied to the piston pump of the mixing-discharging apparatus, the sudden flow rate fluctuations being flow rate fluctuations in the shorter amount of time which would cause sampling distortion in measurements of the flow meter.
