Abstract
The utility model relates to a low-temperature container infusion pipeline, a most preferred infusion pipeline structure in a variety of low-temperature containers; the infusion pipeline is provided with at least one flexible joint; the utility model transforms the traditional infusion pipeline structure with the rigid connection into the simple flexible structure with the elastic connection; thus the utility model not only greatly facilitates and simplifies the compounding and installation process of the matching components, but also lowers the processing cost, significantly reduces the stress centralization of the welded components; the device avoids the phenomenon that the welding seam may be broken as a result of the stress centralization and the low-temperature contraction of the welded components; and the device ensures the use performance and the service life of the low-temperature container, and eliminates the situation of the returning to the factory of the low-temperature container in advance for the maintenance.
Description
Technical field
The utility model relates to a kind of low-temperature (low temperature) vessel, relates in particular to a kind of low-temperature (low temperature) vessel liquid transport pipeline, is liquid transport pipeline structure first-selected in the various low-temperature (low temperature) vessels.
Background technique
Low-temperature (low temperature) vessel is the general name of the equipment of storage and conveying liquified gas, also is the general designation of Dewar type container, low temperature cistern and storage tank.As everyone knows, the temperature of cryogenic liquide is very low, under 101.325Kpa pressure, liquid oxygen-183 ℃, liquid nitrogen-196 ℃, liquid argon-186 ℃, therefore, the necessary heat-insulating property of low-temperature (low temperature) vessel Structural Design Requirement is good, usually adopt the structural type of inside and outside courage combination, interlayer adopts vacuum insulation in the middle of it, interlayer is filled perlite or is adopted coated material to prevent heat conduction, the sealing device of finding time is installed on the shell, utilize the vacuum unit that the interlayer air is found time, make every effort to handle along with increasing of time will be by convection current with this, the heat that approach such as conduction and radiation pass to cryogenic liquide reduces to alap degree, keeps low temperature system proper functioning, guarantees the purpose of the shelf life of cryogenic liquide.In addition, whether the structural design of low-temperature (low temperature) vessel rationally will play crucial effects to its usability.Be located at normally as the cryogenic delivery pipe of low-temperature (low temperature) vessel in the past that an end and the inner bag outside weld together in the vacuum sandwich, another outlet end and shell of tank weld together.The described this mode that is rigidly connected, not only require the relative mounting positions between the counterpart accurate, and its geometrical shape also has strict requirement, otherwise, deviation causes welding back, two ends to produce stress concentrating owing to appearring in the position of the geometrical shape of certain part or mounting hole, in addition in transporting low temperature liquid process pipeline under cold service and produce to shrink, often therefore cause the phenomenon of inside and outside courage place weld cracking to happen occasionally, and then the vacuum of interlayer is damaged, low-temperature (low temperature) vessel is forced to depot repair in advance.
The model utility content
The utility model is at above-mentioned problems of the prior art, provide geometrical shape and relevant position between a kind of counterpart very not strict, it is little influenced by cold service, eliminating in the past, concentrated the contraction with low temperature of stress causes weld cracking, the defective that the vacuum of interlayer is damaged obviously improves the low-temperature (low temperature) vessel liquid transport pipeline that the elasticity in low-temperature (low temperature) vessel working life connects.
To achieve these goals, technology side of the present utility model pacifies as follows:
On its liquid transport pipeline, be provided with a slip joint at least.
Described slip joint is a kind of in bellows, coiler and the U-shaped pipe.
The utility model has the advantages of as follows:
The utility model compared with prior art, owing on its liquid transport pipeline, be provided with the technical measures of a slip joint at least and become the simple structural change that telescopic elasticity connects through the liquid transport pipeline structure that evidence does not just connect conventional rigid, this not only greatly facilitates, simplified the stack mounting operation between the counterpart, but also cut down finished cost, obviously reducing the stress of welded unit concentrates, avoid liquid transport pipeline in infusion process, to shrink the phenomenon that makes weld cracking with low temperature because of pipeline component stress is concentrated, therefore guarantee the usability and the working life of low-temperature (low temperature) vessel, eliminated and cause low-temperature (low temperature) vessel to shift to an earlier date the situation of depot repair.
Description of drawings
Fig. 1 is a main TV structure schematic representation of the present utility model.
Fig. 2 is the structural representation of the utility model position in low-temperature (low temperature) vessel.
Among the figure, 1, shell, 2, inner bag, 3, cryogenic globe valve, 4, slip joint, 5, liquid transport pipeline, 6, cryogenic liquide, 7, vacuum sandwich.
Embodiment
Embodiment
Embodiment of the present utility model is described in detail in conjunction with the accompanying drawings, as shown in Figure 1, 2, technology prepares inner bag 2, the shell 1 of low-temperature (low temperature) vessel routinely, be the vacuum sandwich 7 of coated thermoinsulation material between the two, have the outlet of the cryogenic liquide 6 that links to each other with liquid transport pipeline 5 input ends on the wall of inner bag 2, at least be provided with a slip joint 4 on the liquid transport pipeline 5, the end wall that the output terminal of liquid transport pipeline 5 passes shell 1 links to each other with cryogenic globe valve 3.Described slip joint is a kind of in bellows, coiler and the U-shaped pipe.
It is same as the prior art when the utility model uses.
Claims (2)
1, low-temperature (low temperature) vessel liquid transport pipeline is characterized in that being provided with at least a slip joint (4) on its liquid transport pipeline (5).
2, low-temperature (low temperature) vessel liquid transport pipeline according to claim 1 is characterized in that described slip joint (4) is a kind of in bellows, coiler and the U-shaped pipe.
