Description
Technical field
The utility model relates to a kind of pressure container apparatus, relates in particular to a kind of storage tank of storing cryogenic fluids.
Background technology
Be used for conventional storage tank that cryogenic liquid stores by interior jar with outer jar, inside and outside two-layer composition, in cryogenic liquid is stored in jar in.In observing in the use jar liquid what, all be to connect liquidometer through the level instrumentation nozzle that interior pot bottom picks out, understand the height of liquid level, what of cryogenic liquid reserves in interior jar.When cryogenic liquid adds interior jar, whether fill it up with liquid for the ease of jar in observing, Gu be provided with the survey full packages on the top of liquid, when filling it up with liquid for interior jar, excess liquid is just discharged from the survey full packages.At present; The level instrumentation nozzle set-up mode is that the hole is embedded in pressure vessel in interior pot bottom perforate, and the pressure vessel outer end connects level instrumentation nozzle; A kind of level instrumentation nozzle is spiral coil pipe; Another kind is the crooked pipe of waveform, and all in the cavity between interior jar and the outer jar, the level instrumentation nozzle outer end passes from outer pot bottom level instrumentation nozzle.These two kinds of structure pressure vessels and level instrumentation nozzle all are positioned at pot bottom, and liquid is all bigger to its pressure and impulsive force, and the level instrumentation nozzle structure is produced vibrations, influence the service life of product, also can influence the demonstration result of liquidometer.Survey full packages and also divide two kinds of set-up modes; A kind of set-up mode survey full packages inserts from interior tank top, surveys the vertical section that is that full packages is positioned at jar the inside, surveys full packages and is positioned at jar outside circular arc that adapts with the tank top circular arc that is divided into; Its shortcoming does; It is longer to survey full packages length, and bending spring is also less, and processing is difficulty.Another kind of set-up mode is surveyed full packages and is made up of 2 bend pipes and an adaptor union; Bending is many, complex procedures, and inner bend pipe of inner core and adaptor union welding leakage weldering easily; Welded seal property is not strong; If leak, then in the topping up process, also not reaching the volume that needs has easily just had flow direction to survey full packages, causes and surveys phenomenons such as full packages freezes.
The utility model content
The utility model technical matters to be solved be to provide a kind of rational in infrastructure, survey full, survey liquid level cryogenic liquid storage tank accurately.
The technical scheme of the utility model is following: a kind of cryogenic liquid storage tank; Said cryogenic liquid storage tank is made up of interior jar (1) and outer jar (a 2) two-layer tank body, and said interior jar of (1) bottom is provided with level instrumentation nozzle (4), and interior this jar (1) top is provided with surveys full packages (6); Its key is: jar (1) bottom opening in said; This hole is embedded in pressure vessel (3), and this pressure vessel (3) outer end connects level instrumentation nozzle (4), and said pressure vessel (3) is made up of pressure seat (3a) and gland (3b); Said pressure seat (3a) central authorities have through hole (3c); This pressure seat (3a) edge, upper surface has a circle step, and said gland (3b) covers wedge (3a) upper surface, and it is spacing that terrace is begined a theatrical performance by the institute of pressure seat (3a) in this gland (3b) lower surface; Leave the gap between said gland (3b) end face and circumferential inner wall and the pressure seat (3a), have breach (3d) on this gland (3b) outer circumference surface; Top side-wall hole near in said jar of (1) liquid storage face; This hole is embedded in adaptor union (5); Said adaptor union (5) outer end connects surveys full packages (6); Said survey full packages (6) is positioned at the gap between jar (1) and outer jar (2), and this survey full packages (6) outer end passes from outer jar (2) bottom.Pressure vessel has a gland, and gap around the gland can reduce the impact of liquid, reduces this structure quake, and the binding energy actv. of coil pipe and pressure vessel guarantees its stability.Because of the welded joint of adaptor union and cylindrical shell welded joint and adaptor union and bend pipe all will carry out 100% non-destructive test, air pressure test and air tight test, tightness test, sealing property can be good at guaranteeing.Bend pipe is few, and is rational in infrastructure.Through repeatedly improving, find that said structure is the simplest, and rationally.
Above-mentioned level instrumentation nozzle (4) is spiral coil pipe, and this level instrumentation nozzle (4) outer end passes from outer jar (2) bottom.Coil arrangement satisfies the fluid-tight requirement, has increased pipe heat transfer length, reduces outside heat to inner transmission capacity, can guarantee the accuracy of measuring basically.
Gap filling with insulation material in above-mentioned between jar (1) and outer jar (2).
Above-mentioned level instrumentation nozzle (4) and survey full packages (6) make for 16MnDG or S30408 corrosion-resistant steel.Cryogenic liquid (liquid oxygen, liquid argon, liquid nitrogen) stores level instrumentation nozzle (4) and surveys full packages (6) and adopt the S30408 stainless steel material, and cryogenic liquid (CO2 is low) stores level instrumentation nozzle (4) and surveys full packages (6) and adopt 16MnDG.Two kinds of materials all satisfy its operating needs, and the price of 16MnDG is 1/3rd of 06Cr19Ni10 (S30408) steel pipe approximately on the market.
Beneficial effect: the utlity model has simple in structurely, reasonable in design, reduce the impact of liquid to level instrumentation nozzle, reduce this structure quake, the binding energy actv. of coil pipe and pressure vessel guarantees its stability, and structure is also fairly simple, measures more to show accurate; Reduce survey full packages difficulty of processing, surveyed full packages and level instrumentation nozzle and used the lower alternate material of a kind of price, when having guaranteed quality, also greatly reduced productive costs.
