Specific embodiment
As shown in Figure 1-Figure 3, a kind of gas cylinder connection structure, including shell ontology, the shell ontology includes liner 1 and outer courage
2, the liner 1 and the cooperation of outer courage 2 are installed, and cavity is formed between liner 1 and outer courage 2, and liner 1 and outer courage 2 form bilayer
Structure, effective protection inside stuffing material, cavity is vacuum environment, completely cut off heat transfer, and for liner 1 expand with heat and contract with cold provide it is swollen
Swollen space.
In the liner 1 there is the first end socket portion 3, there is the second end socket portion 4 in the outer courage 2, described first
End socket portion is respectively equipped with endoporus and exit orifice in 3 and second end socket portion 4, further includes movable axis 5, and the movable axis 5 passes through endoporus
And exit orifice, and movable axis 5, respectively with endoporus and exit orifice clearance fit, described 5 one end of movable axis is fixed with the first end socket portion 3 to be connected
It connects, i.e. shell ontology rear end connection is controlled using the clearance fit between axis and axle sleeve, the extension elongation of movable axis 5 adjustable
Range, when being filled with material in bottle, when liner 1 is presented hot, movable axis 5 can translate forward, when the liquid in bottle is finished, liner
1 becomes cold events, and movable axis 5, which can return, to be stretched.This ensure that gas cylinder is always in use safe condition, will not generate should
Power deforms, and bottle is caused to damage, and clearance fit belongs to a kind of mode of axial workpiece cooperation, further includes interference fit and transition
Cooperation, is the common sense known to those skilled in the art, therefore is not illustrated excessively herein, and interval is with the change in location for being combined into movable axis 5
Or change in shape provides surplus.
The second end socket portion 4 includes support sleeve 6, support ring flat-plate 7 and ring flat-plate stiffening plate 8, the support sleeve 6
It is fixedly connected respectively with support ring flat-plate 7, ring flat-plate stiffening plate 8, the exit orifice is arranged on support sleeve 6, and support sleeve 6 is used for
Coordinate with the activity of movable axis 5, the support ring flat-plate 7 is used for supporting 2 interior wall construction rigidity of connecting component and outer courage, can also be
Liner 1 plays liner 1 when deforming certain supporting role, and ring flat-plate stiffening plate 8 is used for supplementing support 7 rigidity of ring flat-plate, and one
As ring flat-plate stiffening plate 8 may be selected that 7 material of ring flat-plate is different and 8 rigidity of ring flat-plate stiffening plate is more than the steel for supporting ring flat-plate 7 with support.
Support sleeve 6, support ring flat-plate 7 and the ring flat-plate stiffening plate 8 passes through integrally welded formula structure, integral structure
The stability of enhancing structure, welding are undoubtedly most easy, economic processing method, with existing solder joint local environment not
Together, it is not likely to produce weld seam breach.
The ring flat-plate stiffening plate 8 is bonded with support ring flat-plate 7, and the thickness in stress section is directly strengthened in fitting, hence it is evident that improves
Fatigue strength limit.
Auxiliary end socket 9 is equipped in the first end socket portion 3, the auxiliary end socket 9 is fixedly connected with movable axis 5, Gu
Determine there are many connection modes, be such as interference fitted, be welded to connect or bolt shows fixation, it is not made excessively to illustrate herein and limitation.
It is equipped with the first reserved room 10 of hollow out in described first end socket portion 3, the described first reserved room 10 is equipped with the
One overcharges hole, and described first overcharges bore dia less than the charge mouth diameter on shell ontology, and the described first reserved room 10 passes through
First overcharges hole is connected with the storing space in liner 1, and the first reserved room 10 is to prevent gas cylinder overfilling, the first reserved room
First that a 3.5mm has been opened on 10 overcharges hole, and charge mouth (diameter is 17mm) flow is more than anti-during gas cylinder filling liquid
The flow flowed inside is overcharged, ensures that under the specified minimum charge pressure of cylinder filling after saturation, interior pressure rises to safety valve unlatching
During pressure, liner 1 is discontented with liquid, and effective protection gas cylinder uses under design condition always.
The auxiliary end socket 9 overcharges hole equipped with second, and the auxiliary end socket 9 is internally provided with the second reserved room 11,
The second reserved room 11 overcharges hole by second and is connected with the first reserved room 10, and the single first reserved room 10 has been difficult to
All risk insurance demonstrate,proves leakproofness and anti-overcharge, therefore sets the smaller second reserved room 11 of relative volume, and one has been opened on the second reserved room 11
The second of 3.5mm overcharges hole, and material may also flow into inside auxiliary end socket 9, and effect in addition to this is just to maintain 5 axis of movable axis
Verticality and the effect for supplementing 1 structural strength of liner.
The support ring flat-plate 7 is equipped with several matching holes 12, and ring flat-plate 7 is supported to be equipped with several notches along outer circumferential edges
13, matching hole 12 is used for the stress deformation that support ring flat-plate 7 is coordinated to occur, and avoids the tear generated due to internal stress or permanent curved
It is bent.
The matching hole 12 is round or elliptical shape, and the notch 13 is arcuate shape, such shape stress
Uniformly, meet the requirement of the design, and matching hole 12 and notch 13 can be circumferentially arranged symmetrically, and improve integrally-built stabilization
Property.
The support ring flat-plate 7 is fixed by welding on outer 2 inner wall of courage, can set multiple solder joints, without with notch 13
Or other structures generate conflict, because in the bottom of outer 2 inner wall of courage, therefore facilitate processing, reduce manufacturing procedure.
The beneficial effects of the utility model：A kind of gas cylinder connection structure setting liner provided by the utility model and outer
Courage, liner and outer courage front end using rigid connection, back end activity cooperation, in this way according to the principle expanded with heat and contract with cold, rear end avoids
The drawing crack expanded with heat and contract with cold to weld seam of gas cylinder, the relative contact between the liner of rear end and outer courage reduces nearly three/
Two, the path of heat transfer reduces nearly half, simple in structure, stable, has practicability and economy.
