<p>The present invention relates to a gas injection device, which charges gas into the enclosed space of insulating glass, and more specifically, to a gas injection device, which does not provide stress caused by high pressure and low pressure to the insulating glass by controlling the pressure of the enclosed space during gas charging. The gas injection device of the present invention comprises a gas storage unit to store gas; an injection unit, which injects the gas stored in the gas storage unit to the enclosed space and controls the injection speed of the gas; an suction unit, which includes a vacuum pump to suck the air in the enclosed space and a suction controlling unit to control the suction speed of the air; a control unit, which controls the injection speed and the suction speed by controlling the injection unit and the suction unit, thus controlling the pressure in the enclosed space, and a pneumatic regulator to prevent gas leakage and perform precise gas control.</p> |
