Claims

[Claims for Utility Model Registration] A storage tank for low-temperature liquefied gas formed by a heat insulating wall having an upper opening; a lid for closing the upper opening of the storage tank; A nozzle chip that is equipped with one or more discharge holes for limiting the flow rate; A nozzle chip holder that is fixed to the lower end of the storage tank above the nozzle chip and is open in the center; The nozzle chip A nozzle having an open center portion that removably engages with the holder and clamps the nozzle chip with the nozzle chip holder to removably fix the nozzle chip to the lower end of the storage tank. Chip holder: an outer wall τ of the vaporized gas introduction chamber that surrounds the nozzle chip holder, the nozzle chip, and part of the outer periphery and lower surface of the nozzle chip holder, and has an opening in the center of the lower surface through which low-temperature liquefied gas can pass. A valve mechanism including a valve body and a valve seat for controlling the flow down or stopping of the low temperature liquefied gas from the discharge hole of the nozzle chip; a supply pipe for the low temperature liquefied gas passing through the lid body and the liquid level; A control sensor and a piston rod that is connected to the valve body at its lower end and deflects; a vaporized gas discharge pipe provided on the lid body; and a low temperature liquefied gas supply pipe that opens and closes based on signals from the low temperature liquefied gas liquid surface side control sensor. In the low-temperature liquefied gas quantitative flow device equipped with an on-off valve, the nozzle tip holder is provided with a valve seat of a valve mechanism for controlling the flow of the low-temperature liquefied gas from the discharge hole or the stoppage of the flow. A quantitative flow device for low-temperature liquefied gas, which is characterized by:
