More Information
Summary:A low temperature liquefied gas outflow device wherein an outflow nozzle (14) having a plurality of through-holes (15) is provided through the base of a heat-insulating container (1) having an opening at the top, and a cover member (2) closing the opening, a control device (16) for selectively opening or closing any desired number of the plurality of through-holes (15) provided in the outflow nozzele (14) is provided. The heat-insulating container (1) has a level sensor (7) located within the heat-insulating container (1), a liquefied gas supply conduit (3) running through the cover member (2), a vaporized-gas exhaust conduit (5) provided in the cover member (2), and a check valve (4) inserted into the liquefied gas supply conduit (3), operating in response to a signal from the level sensor (7). The control device (16) for selectively opening or closing the through-holes (15) comprises a plurality of valve elements (18 19) for selectively closing the through-holes (15), and an elevation cylinder (22) for controlling the operation of the plurality of valve elements (18, 19). The plurality of valve elements (18, 19) are arranged concentrically with each other, or arranged separately in the horizontal direction from each other.
