See Fig. 1 and Fig. 2, by the vertical cryogenic insulated cylinder with special neck tube that embodiment 1 obtains, bottle exterior part that also must increase the outer pipeline of bottle that comprises pipeline control system 4 could use after becoming vertical cryogenic insulated cylinder system.The outer pipeline of bottle comprises pressure charging valve 44, combined pressure regulating valve 45, gas valve 46, liquid phase valve 47, bleed valve 48 and security component 49.Combined pressure regulating valve 45 is that U.S. REGO company produces.Combined pressure regulating valve 45 is provided with inlet opening 45-1, output inlet opening 45-2, delivery outlet 45-3, boost-up circuit, economized circuit and pressure-regulating device.Boost-up circuit is between inlet opening 45-1 and output inlet opening 45-2, and economized circuit is between output inlet opening 45-2 and delivery outlet 45-3.Look nut by the rotation pressure-regulating device can be regulated to the fluid that flows into from inlet opening 45-1 with to the pressure threshold of the fluid that flows out from delivery outlet 45-3.The pressure threshold of inlet opening 45-1 (being called first pressure threshold) can be regulated in 0.5 to 2.5MPa scope, the pressure threshold of delivery outlet 45-3 (being called second pressure threshold) is a high definite numerical value (present embodiment is selected 0.1MPa in 0.05 to 0.15MPa scope) than first pressure threshold.First pressure threshold of combined pressure regulating valve 45 is meant that the outer hydrodynamic pressure of inlet opening 45-1 of combined pressure regulating valve 45 increases to when reaching this threshold value, the valve closing that is positioned at 45-1 place, inlet opening of combined pressure regulating valve 45, thus cut off boost-up circuit; When having only the outer pressure of the inlet opening 45-1 of combined pressure regulating valve 45 less than first pressure threshold, the valve that is positioned at 45-1 place, inlet opening could be opened, and makes the boost-up circuit conducting.Second pressure threshold of combined pressure regulating valve 45 is meant that the interior hydrodynamic pressure of delivery outlet 45-3 of combined pressure regulating valve 45 increases to when reaching this threshold value the valve opening that is positioned at delivery outlet 45-3 place of combined pressure regulating valve 45, thereby conducting economized circuit; When having only pressure in the delivery outlet 45-3 of combined pressure regulating valve 45 greater than second pressure threshold, the valve that is positioned at delivery outlet 45-3 place could be opened, and make the economized circuit conducting, if the pressure in the delivery outlet 45-3 of combined pressure regulating valve 45 is during less than second pressure threshold, be positioned at the valve closing at delivery outlet 45-3 place, and economized circuit is cut off.Pressure charging valve 44, gas valve 46, liquid phase valve 47 and bleed valve 48 are low temperature resistant angle valve.Security component 49 comprises pressure gauge 49-1, safety valve 49-2, rupture disk assembly 49-3 and cross fitting 49-4.

The import of pressure charging valve 44 links to each other by the side port of connecting tube with the exocoel first passage 31 of distributor 3.The outlet of pressure charging valve 44 links to each other with the inlet opening 45-1 of combined pressure regulating valve 45 by connecting tube.The output inlet opening 45-2 of combined pressure regulating valve 45 links to each other by the side port 34-1 of connecting tube with the inner chamber first passage 34 of distributor 3.The delivery outlet 45-3 of combined pressure regulating valve 45 links to each other by the side port of connecting tube with the exocoel second channel 32 of distributor 3.Externally export the port of gas when the outside port of gas valve 46 is to use, the internal port of gas valve 46 links to each other by the side port of connecting tube with the exocoel third channel 33 of distributor 3.

Liquid phase valve 47 outside ports input or output the port of cryogenic liquid gas when being to use, the internal port of liquid phase valve 47 links to each other with inner chamber second channel 35 side port of distributor 3 by connecting tube.When being to use, the outside port of atmospheric valve 48 externally emits the gas in the inner lining 20 so that carry out liquid and fill or be convenient to and the pressure threshold of combined pressure regulating valve 45 is confirmed the internal port of atmospheric valve 48 links to each other by the side port of connecting tube with the inner chamber third channel 36 of distributor 3.

The second side port 34-2 of the inner chamber first passage 34 of distributor 3 links to each other with the cross fitting 49-4 of security component 49 by connecting tube, and other 3 ports of this cross fitting 49-4 link to each other with rupture disk assembly 49-3 with pressure gauge 49-1, safety valve 49-2 respectively.

Vertical cryogenic insulated cylinder system that should use-case before use, air in the interlayer between inner bag 2 and the shell 1 is evacuated by the vacuum molecule pump assembly discharges vertical cryogenic insulated cylinder, reach 0.01Pa until degree of vacuum, first pressure threshold of the combined pressure regulating valve 45 of vertical cryogenic insulated cylinder is arranged on 0.85MPa, and second pressure threshold of combined pressure regulating valve 45 then is 0.95MPa.In use, open pressure charging valve 44, liquid air in the inner lining 20 (also can be liquid oxygen, liquid argon gas or liquid nitrogen etc.) enters in the supercharging coil pipe 41 and the vaporization of being heated, then successively through getting back in the inner lining 20 behind pressure charging valve 44, the combined pressure regulating valve 45, make the pressure in the inner lining 20 increase, when reaching the first pressure threshold 0.85MPa, the boost-up circuit of combined pressure regulating valve 45 is closed automatically.When using gas, pressure charging valve 44 and gas valve 46 are in the state of opening simultaneously, when reaching the second pressure threshold 0.95MPa as pressure in the inner lining 20, the economized circuit of combined pressure regulating valve 45 is opened, and preferentially the gas in the inner lining 20 is passed through successively inner chamber first passage 34, the economized circuit of combined pressure regulating valve 45, the outside air feed of vaporization coil pipe 42 and gas valve 46 backs of distributor 3.Normal as pressure in the inner lining 20, then liquid air is from the flow through outside air feed of inner chamber second channel, vaporization coil pipe 42 and gas valve 46 backs of liquid in-out pipe 43-2, distributor 3 of the lower end mouth of liquid in-out pipe 43-2.Gas-liquid mixed state liquid air by supercharging coil pipe 41 after, become gas-liquid mixed state liquid air and pass through pressure charging valve 44 and combined pressure regulating valve 45 successively, flow through then the vaporization coil pipe 42, liquid air in vaporization coil pipe 42 by with vaporization coil pipe 42 contacted casing cylinders 11 and carry out sufficient heat exchange with external environment, thereby be converted into gas, outwards air feed.When the opening degree of gas valve 46 is big, only depend on a vaporization coil pipe 42 that is arranged in the bottle liquid air that flows through wherein can't to be gasified totally.Level meter 72 is in order to observe the amount of the cryogenic liquide in the inner lining 20 intuitively.Liquid phase valve 47 charging and discharging in order to the control cryogenic liquide.Bleed valve 48 reduces the pressure in the inner lining 20 in order to discharge the gas in the inner lining 20.Security component 49 is in order to preventing that gas cylinder from leaking thermal loss normally and causing pressure of the inside of a bottle to rise, or go to pot acceleration under the back and the condition of catching fire of vacuum is leaked the pressure that thermal conductance causes and risen.When surpassing the safety pressure of the 1.12MPa set, opens the gas in inner lining 20 of the safety valve 49-2 in the security component 49, gas in external world's release inner lining 20, also rise too fast as pressure, rupture disk assembly 49-3 in the security component 49 will open pressure release, to guarantee the pressure security of gas cylinder.Pressure gauge 49-1 is used for observing the pressure of understanding inner bag 2 gases.
