Description
Technical field
The utility model belongs to a kind of container storing liquid nitrogen, is specifically related to a kind of safety installations of liquid nitrogen container.
Background technique
In some production process, the use amount of liquid nitrogen is very large.During use, need to carry out liquid nitrogen packing from low temperature storing tank to liquid nitrogen container.
Liquid nitrogen container, as the separation container of liquid nitrogen, will export liquid nitrogen by the mode of supercharging.In pressurization, operator will note observing manometric change, if the force value on pressure gauge arrives use pressure, at once close pressure charging valve, stop pressurization.
The liquid nitrogen container of packing in use, often to recycle frequently, if when liquid nitrogen container supercharging exports liquid nitrogen, because closedown pressure charging valve is forgotten in operate miss, tank body will break, liquid nitrogen ejection in tank body, liquid nitrogen is cryogenic liquide, if accidentally contact or suck after in human body and can cause frostbite, suffocate.
Summary of the invention
The utility model proposes for solving prior art Problems existing, its objective is the safety installations providing a kind of liquid nitrogen container.
The technical solution of the utility model is: a kind of safety installations of liquid nitrogen container; comprise tank body; tank base is provided with multiple universal wheels; outer wall is provided with handrail, and axis place, top is provided with joint, and the inner chamber of tank body is communicated with connecting tube; the other end of connecting tube is communicated with pressure maintaining valve, pressure charging valve and joint successively; joint side-walls is also provided with atmospheric valve, liquid valve, the first safety valve, and the first safety valve is connected in series with the second safety valve, pressure gauge, and tank body top is provided with vacuum protection cover.
Described manometric range is 0 ~ 0.6MPa.
The utility model structure is simple, convenient mobile, makes tank body pressure energy remain in safety range, add the reliability that liquid nitrogen exports, avoid the infringement to equipment and operator by increase pressure maintaining valve and safety valve.
Accompanying drawing explanation
Fig. 1 is plan view of the present utility model;
Fig. 2 is plan view of the present utility model.
Wherein:
1 tank body 2 universal wheels
3 handrail 4 connecting tubes
5 pressure maintaining valve 6 pressure charging valves
7 joint 8 atmospheric valves
9 liquid valve 10 first safety valves
11 second safety valve 12 pressure gauges
13 vacuum protection covers.
Embodiment
Below, with reference to drawings and Examples, the utility model is described in detail:
As shown in Figure 1, 2; a kind of safety installations of liquid nitrogen container; comprise tank body 1; multiple universal wheels 2 is provided with bottom tank body 1; outer wall is provided with handrail 3; axis place, top is provided with joint 7; the inner chamber of tank body 1 is communicated with connecting tube 4; the other end of connecting tube 4 is communicated with pressure maintaining valve 5, pressure charging valve 6 and joint 7 successively; joint 7 side-walls is also provided with atmospheric valve 8, liquid valve 9, first safety valve 10; first safety valve 10 is connected in series with the second safety valve 11, pressure gauge 12, and tank body 1 top is provided with vacuum protection cover 13.
In the utility model, the operating pressure of tank body 1 is about 0.1MPa, and the range of choice for use pressure gauge 12 is 0 ~ 0.6MPa, is convenient to the intuitive that raising operator observe pressure gauge 12.
Pressure charging valve 6 is connected with pressure maintaining valve 5, and the liquid nitrogen pressure outputted in pressure charging valve 6 can be maintained 0.07MPa by pressure maintaining valve 5, therefore, even if pressure charging valve 6 is in normally open, also there will not be the contingency that tank body 1 breaks.
The protection value of the first safety valve 10, second safety valve 11 is 0.09MPa.
The utility model structure is simple, convenient mobile, makes tank body pressure energy remain in safety range, add the reliability that liquid nitrogen exports, avoid the infringement to equipment and operator by increase pressure maintaining valve and safety valve.
