ことが考えられる。The most efficient method is to install a float in the liquefied gas storage tank.
It is conceivable that the vaporized gas in the tank is caused to flow away by vertical movement of the foot V to fluctuate the internal pressure, and the liquefied inert gas is caused to flow from the liquefied gas cylinder into the storage tank due to this pressure change.

A storage tank, a liquefied gas zero dripping valve that is opened and closed by a drive device, a nozzle plate that drips υ liquefied gas from the dripping pulp, a gas nozzle that releases the vaporized gas from the upper air of the upper storage tank through the internal pressure regulating pulp, and a gas nozzle that releases the vaporized gas from the original tank. I would like to use a liquefied gas dripping device that is composed of a packet-type float pulp that opens and closes the liquefied gas D supply port to the storage tank, and can precisely control the amount of dripping, although the control 11vc setting is simple. There is more to do.

And this D storage tank 17) The inner surface is a liquefied inert gas zero source tank 5
During the initial liquid supply, the system suppresses rapid vaporization and pressure rise until the storage tank ID temperature drops sufficiently, stabilizes the tank internal pressure early, shortens liquid supply preparation time, and saves liquefied scum. To prevent this, apply a Teflon coat.

に保持する。The vaporized gas from the storage cypress ID upper air passage 7D is guided through the discharge pipe system 8 to the nozzle plate 4υ outer circumference slK, and then to the gas nozzle 9.
The liquefied gas D is prevented from vaporizing and freezing by shielding the liquefied gas released and dripping with a low-temperature inert gas. On the other hand, vaporized gas is guided into the electromagnetic drive device 2 through the vaporized gas induction port 10 to cool the solenoid 11 and prevent burnout. Further, an internal pressure adjusting pulp 13 and a safety valve 14 are installed in the discharge pipe system 8 to adjust the internal pressure of the storage tank 1'7). Excess vaporized gas is guided from a separate pipe system (not shown) to the seamer seaming part and used as υ undercover gassing gas to reduce the amount of air sealed in the can.・D liquid supply part into the storage tank 1 is equipped with a packet-type float pulp 15, which automatically adjusts the opening amount of the valve υ according to the liquid level, and operates to keep the liquid level constant at all times, thereby stabilizing the liquid level. , continuous liquid supply is possible. In addition, the packet type float pulp 15 operates independently of changes in the pressure setting of the storage tank 1'Z), allowing the gas pressure in the storage tank 1 to be adjusted, which is effective in saving gas. In the figure, 16 is a heater for maintaining the internal pressure of the tank, and a machine control unit 11fjil that prevents the internal pressure of the storage tank 12) from falling below a set value.
17 is activated to heat the tank internal pressure maintenance heater and vaporize the liquefied gas. Internal pressure adjustment pulp 13 for stiff vaporized gas
is opened and released continuously to maintain the internal pressure of the reservoir tank 1'7) at the set value.

KoO
By lowering the flow rate, D@defeats when filling,
In order to make it possible to stabilize the filling amount, the υ invention has the above-mentioned simple configuration, and the liquid D supplied to the storage tank 1 is connected to the liquefied gas υ in the storage tank 10, regardless of the internal pressure of the original tank 5.
O performed by the level 71 allows continuous and stable liquid supply and also keeps the liquid level constant. Reservoir tank 17) By coating the inner surface with Teflon, a temporary insulation effect can be obtained, and the preparation time until the start can be shortened. Dripping valve and nozzle plate 4 and attachment I
By forming the Is product with resin, it is possible not only to prevent frost from adhering to the surfaces of the nozzle plate 4, etc., but also to prevent the nozzle holes from freezing. Since the structure is such that vaporized gas is guided and blown to the outer periphery of the nozzle plate 4υ, not only is there a cooling effect of the liquefied gas υ, but also frosting (freezing) can be prevented.
