Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1: carbon dioxide liquid storage tank, including outer cylinder body 1, inner barrel 2, pearl
Light layer of sand 3, vacuum valve 4, relief valve 17, tapping valve 5, balanced valve 6, lower combination valve 8,
Upper liquid feed valve 10, residual night tapping valve 9, relief valve 12, gauge valve 7, liquidometer 20, pressure
Power table 19, surveys full valve 18, total liquid feed valve 13, fills irrigation and drainage and fill mouth 14 and three-way valve 11.In
Cylinder 2 is arranged in outer cylinder body 1, and pearly-lustre layer of sand 3 is wrapped in the outside of inner barrel 2, vacuum
Valve 4 is arranged on outer cylinder body 1, for evacuation.It is provided with boosting to adjust in the upper end of outer cylinder body 2
Joint valve 15.Balanced valve 6, Pressure gauge 19, relief valve 17 and three-way valve 11 are connected to inner core
The upper end of body 2.The other end of balanced valve 6 is connected with balance air inlet/outlet.Three-way valve 11
Another two ends connect two relief valve 12.Tapping valve 5 and lower combination valve 8 are connected to inner barrel 2
Lower end.The other end of lower combination valve 8 is connected with total liquid feed valve 13, total liquid feed valve 13
The other end with fill irrigation and drainage and fill mouth 14 and be connected.Residual night tapping valve 9 and upper liquid feed valve 10 be arranged on down
Between combination valve 8 and total liquid feed valve 13.The other end of upper liquid feed valve 10 and inner barrel 2
Upper end connects.Liquidometer 20 is connected to the two ends of inner barrel 2 by gauge valve 7.
Liquid CO 2 is compared with liquid oxygen, nitrogen, argon, and its liquid phase region is the narrowest,
Easily solidification blocking pipeline.Before topping up, in groove, pressure should be not less than 1.0Mpa, and pressure gauge valve should
Being in the state of standard-sized sheet, liquidometer also should be at duty.With metal vacuum flexible pipe by tank car
The irrigation and drainage of filling of leakage fluid dram and this equipment fill mouth and connect, the tapping valve of crack tank car, make a small amount of
Liquid carbon dioxide enters the vaporization of metal vacuum flexible pipe, from residual drain valve discharge at night, true to metal
Empty flexible pipe carries out blowing down displacement.After a few minutes, close residual liquid discharge valve, open lower combination valve,
Liquid CO 2 is allowed to enter in inner barrel from bottom.When surveying full valve ejection liquid, explanation
To be full of, close lower combination valve, stop topping up, open drain valve at residual night simultaneously, discharge residual
Remaining liquid.Such as hypertonia in inner barrel, can use relief valve pressure release, but 1.0Mpa must not be less than.
As long as liquid source pressure is higher than pressure in groove, topping up just can be smoothed out.Liquid CO 2 band
When pressure stores, standard-sized sheet answered by pressure gauge valve, liquidometer, three-way valve, remaining valve closing.But groove
Interior pressure must not be higher than 2.16Mpa, does not the most allow less than 1.5Mpa simultaneously.
It is emphasized that: be the most only preferred embodiment of the present utility model, the most right
This utility model makees any pro forma restriction, every according to technical spirit pair of the present utility model
Any simple modification, equivalent variations and the modification that above example is made, all still falls within this practicality
In the range of new technique scheme.
