Abstract
The utility model discloses an overflow detecting pipe structure of a low-temperature liquid storage tank, which mainly comprises the low-temperature liquid storage tank. The low-temperature liquid storage tank consists of an inner tank (1) and an outer tank (2), the side wall of the upper side of the inner tank (1) close to the liquid storage level is provided with a hole, a pipe joint (3) is embedded into the hole, the outer end of the pipe joint (3) is connected with an overflow detecting pipe (4), the overflow detecting pipe (4) is arranged in the gap of the inner tank (1) and the outer tank (2), and the outer end of the overflow detecting pipe (4) extends out of the bottom of the outer tank (2). The overflow detecting pipe structure of the low-temperature liquid storage tank has the advantages of simple structure and reasonable design, process difficulty is reduced, the overflow detecting pipe is made of a substituted material which is lower in price, and quality is guaranteed while production cost is reduced greatly.
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 and surveys the full packages structure.
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 the time of in the utilization cryogenic liquid being added jar, whether fill it up with liquid for the ease of in observing jar, be provided with the survey full packages on the top of liquid admittedly, when filling it up with liquid for interior jar, excess liquid is just from the discharge of survey full packages.Present survey full packages divides 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 the jar the inside, and it is the circular arc that adapts with the tank top circular arc that the survey full packages is positioned at a jar outer part; 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 is to provide a kind of cryogenic liquid storage tank simple, rational in infrastructure to survey the full packages structure.
The technical scheme of the utility model is following: a kind of cryogenic liquid storage tank is surveyed the full packages 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; Its key is: near the top side-wall hole of in said jar of (1) liquid storage face, this hole is embedded in adaptor union (3), and said adaptor union (3) outer end connects surveys full packages (4); Said survey full packages (4) is positioned at the gap between jar (1) and outer jar (2), and this survey full packages (4) outer end passes from outer jar (2) bottom.Said structure, 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.
Gap filling with insulation material in above-mentioned between jar (1) and outer jar (2).
Above-mentioned survey full packages (4) makes for 16MnDG or S30408 corrosion-resistant steel.Cryogenic liquid (liquid oxygen, liquid argon, liquid nitrogen) stores surveys full packages (4) employing S30408 stainless steel material, and cryogenic liquid (CO2 is low) stores survey full packages (4) and adopts 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, reduced difficulty of processing, survey full packages and used the lower alternate material of a kind of price, when having guaranteed quality, also greatly reduce productive costs.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
As shown in Figure 1, a kind of cryogenic liquid storage tank survey full packages structure mainly comprises cryogenic liquid storage tank, and said cryogenic liquid storage tank is formed with outer jar 2 two-layer tank bodies by interior jar 1, the gap filling with insulation material between said interior jar 1 and outer jar 2.Near the top side-wall hole of in said jar of 1 liquid storage face, this hole is embedded in adaptor union 3, and said adaptor union 3 outer ends connect surveys full packages 4, and in the gap of said survey full packages 4 between interior jar 1 and outer jar 2, these survey full packages 4 outer ends pass from outer jar 2 bottoms.Said survey full packages 4 makes for 16MnDG or S30408 corrosion-resistant steel.
Although more than combine accompanying drawing that the preferred embodiment of the utility model is described; But the utility model is not limited to the above-mentioned specific embodiment; The above-mentioned specific embodiment only is schematic rather than determinate, and those of ordinary skill in the art is under the enlightenment of the utility model, under the prerequisite of the utility model aim and claim; Can make multiple similar expression, such conversion all falls within the protection domain of the utility model.
Claims (3)
1. a cryogenic liquid storage tank is surveyed the full packages 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, it is characterized in that: near the top side-wall hole of in said jar of (1) liquid storage face; This hole is embedded in adaptor union (3); Said adaptor union (3) outer end connects surveys full packages (4), and said survey full packages (4) is positioned at the gap between jar (1) and outer jar (2), and this survey full packages (4) outer end passes from outer jar (2) bottom.
2. survey the full packages structure according to the said cryogenic liquid storage tank of claim 1, it is characterized in that: the gap filling with insulation material in said between jar (1) and outer jar (2).
