Abstract
The utility model discloses a liquid level meter connection pipe structure of a low-temperature liquid storage tank. The liquid level meter connection pipe structure mainly comprises a low-temperature liquid storage tank. The low-temperature liquid storage tank consists of an inner tank (1) and an outer tank (2); the bottom of the inner tank (1) is provided with a hole, in which a pressure measuring device (3) is embedded; the outer end of the pressure measuring device (3) is connected with a liquid level meter connection pipe (4); the pressure measuring device (3) consists of a pressure measuring seat (3a) and a gland (3b); a through hole (3c) is arranged in the center of the pressure measuring seat (3a); the gland (3b) covers the upper end surface of the pressure measuring seat (3a); the lower end surface of the gland (3b) is limited by a step surface of the pressure measuring seat (3a); gaps are retained between the top surface and the pressure measuring seat (3a) as well as between the circumferential inner wall of the gland (3b) and the pressure measuring seat (3a); and a through hole (3d) is arranged in the outer circumferential surface of the gland (3b). The liquid level meter connection pipe structure is simple, reasonable in design and capable of reducing the liquid impact and the structure vibration; and through the combination of a coiler and the pressure measuring device, the stability can be effectively ensured, so that the structure is simpler and the measurement is more accurate.
Description
Technical field
The utility model relates to a kind of pressure container apparatus, relates in particular to a kind of storing cryogenic fluids storage tank liquid-level meter joint pipe structure.
Background technique
Be used for conventional storage tank that cryogenic liquide stores by interior jar with outer jar, inside and outside two-layer composition, in cryogenic liquide is stored in jar in.In observing in the use jar liquid what, all be to connect level meter through the level instrumentation nozzle that interior pot bottom picks out, understand the height of liquid level, what of cryogenic liquide reserves in interior jar.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 impact force, and the level instrumentation nozzle structure is produced vibrations, influence the working life of product, also can influence the demonstration result of level meter.
The model utility content
The utility model technical problem to be solved be to provide a kind of rational in infrastructure, measure cryogenic liquid storage tank level instrumentation nozzle structure accurately.
The technological scheme of the utility model is following: a kind of cryogenic liquid storage tank level instrumentation nozzle structure; Mainly comprise 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 its key is: jar (1) bottom opening in said, and this hole is embedded in pressure vessel (3); This pressure vessel (3) outer end connects level instrumentation nozzle (4); Said pressure vessel (3) is made up of pressure seat (3a) and gland (3b), and said pressure seat (3a) central authorities have through hole (3c), and this pressure seat (3a) edge, upper-end surface has a circle step; Said gland (3b) covers wedge (3a) upper-end surface; It is spacing that terrace is begined a theatrical performance by the institute of pressure seat (3a) in this gland (3b) lower end surface, leaves the gap between said gland (3b) end face and circumferential inner wall and the pressure seat (3a), has breach (3d) on this gland (3b) outer peripheral surface.Pressure vessel has a gland, and gap around the gland can reduce the impact of liquid, reduces this structure quake, and the binding energy of coil pipe and pressure vessel effectively guarantees its stability.
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) makes for 16MnDG or S30408 stainless steel.Cryogenic liquide (liquid oxygen, liquid argon, liquid nitrogen) stores level instrumentation nozzle (4) and adopts the S30408 stainless steel material, and cryogenic liquide (carbon dioxide is low) stores level instrumentation nozzle (4) and adopts 16MnDG.Two kinds of materials all satisfy its usage requirement, 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, reduce this structure quake, the binding energy of coil pipe and pressure vessel effectively guarantees its stability, and structure is also fairly simple, measures more to show accurate.
