Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is based on a cooling trap interposed between a high-performance pump and an exhaust pump, and a low-temperature cooling II.
&t-Relates to a solenoid valve type variable pressurization low temperature Iv medium vessel for visual inspection.

One of the conventional Jin stocks! For sushi, as shown in w and l-1, a pipe bl is provided which opens into the circular space of the container body a and the liquid i1 and the horizontal part of the wood, and a manual booster valve C and a heat It has also been proposed to intervene with a exchanger C1 to remove liquid nitrogen r, but in order to take out the liquid nitrogen r, open the booster valve C and the liquid take-out valve eV by hand and open the 9th section of the circle a of the container body. Since it is necessary to increase the gas pressure r of In the figure, f is a gas release valve (manual) and g is a safety valve.

It has also been proposed to connect compressed air to the container body via a solenoid valve and control the electromagnetic valve to automatically control the extraction of liquid nitrogen, but this method requires separate equipment. There is a drawback to kll'. Historically, the space inside the container body was pressurized, and a
A method that automatically controls the valve has also been proposed, but this method has the disadvantage of causing a large amount of loss because liquid nitrogen may be blown out when taken out.

The present invention provides a low-temperature refrigerant container that eliminates the conventional t-hole cutout, 41, has a simple structure, is suitable for purposefully controlling the removal of low-temperature refrigerant from the container, and does not cause loss of low-temperature refrigerant. For that purpose, a notch 17" with one end and the other end open, respectively, is provided in the low-temperature refrigerant container neck and space inside the container body, and a heat exchanger and a Sankiden 1Hffk are inserted in the pipe. However, the three-way electromagnetic cell has electricity (I
! Controlled by the number, the space is opened between the outside space and the pipe is closed, or the space is closed off from the outside space and the pipe is opened. .

Embodiments of the present invention will be described below with reference to the drawings.

When energized, the pipe (5) is opened, and the opening of the space (3) to the outside space is blocked, so that the liquid bond Op passes through the heat exchanger (6) and the bean paste generated. When the gas is released into the space (3), the pressure there rises, and using that pressure, several nitrogen atoms flow out from the liquid take-off valve (9). Thus, for example, when the a-plane sensor of a liquid nitrogen
) can be controlled automatically.

According to the present invention, a heat exchanger and a 30,000-meter electric cylinder are inserted into a pipe that has one end and another opening in the low-temperature refrigerant container and the space in the container body, respectively, and The magnetic cell is controlled by an electric signal to open the space to the outside and close the space, or close the space to the outside space and open it to the outside. Compared to the conventional type, the configuration is simpler and the lower temperature refrigerant can be automatically controlled according to the liquid level in the replenishing low-temperature refrigerant container. do.
