Fig. 3 is support ring-plane structure schematic diagram of the invention.
Specific embodiment
As shown in Figure 1-Figure 3, a kind of gas cylinder connection structure, including shell ontology, the shell ontology include liner 1 and outer gallbladder
2, the liner 1 and outer gallbladder 2 are coupled, and cavity is formed between liner 1 and outer gallbladder 2, and liner 1 and outer gallbladder 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.
There is the first sealing head 3 in the liner 1, there is the second sealing head 4 in the outer gallbladder 2, described first
It is respectively equipped with inner hole and exit orifice in sealing head 3 and the second sealing head 4, further includes movable axis 5, the movable axis 5 passes through inner hole
And exit orifice, and movable axis 5 is fixed and is connected with inner hole and exit orifice clearance fit, described 5 one end of movable axis and the first sealing head 3 respectively
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 be translate forward, when the liquid in bottle is finished, liner
1 turns cold contraction, and movable axis 5, which can return, to be stretched.This ensure that gas cylinder is always in use safe condition, it will not generate and answer
Power deformation, causes to damage to bottle body, and it further includes interference fit and transition that clearance fit, which belongs to a kind of mode of axial workpiece cooperation,
Cooperation, is 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.
Second sealing head 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 to
Cooperate with the activity of movable axis 5, the support ring flat-plate 7 is used to support 2 interior wall construction rigidity of connecting component and outer gallbladder, can also be
Certain supporting role is played to liner 1 when liner 1 deforms, and ring flat-plate stiffening plate 8 is used to supplement support 7 rigidity of ring flat-plate, 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 greater 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, not with existing solder joint local environment
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 reinforced in fitting, hence it is evident that improves
Fatigue strength limit.
It is equipped with auxiliary end socket 9 in first sealing head 3, the auxiliary end socket 9 is fixedly connected with movable axis 5, Gu
Determine there are many connection types, such as interference fit, welded connecting or bolt show fixation, do not make excessively elaboration and limitation to it herein.
It is equipped with the first reserved room 10 of hollow out in described first sealing head 3, the reserved room 10 of described first is equipped with the
One overcharges hole, and described first overcharges bore dia less than the charge mouth diameter on shell ontology, and the reserved room 10 of described first 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 greater than anti-during gas cylinder filling liquid
The flow flowed inside is overcharged, is guaranteed after being saturated under the specified minimum charge pressure of cylinder filling, interior pressure rises to safety valve unlatching
When pressure, liner 1 is discontented with liquid, and effective protection gas cylinder uses under design condition always.
The auxiliary end socket 9 is equipped with second and overcharges hole, is equipped with the second reserved room 11 inside the auxiliary end socket 9,
The reserved room 11 of described second overcharges hole by second and is connected with the first reserved room 10, and the reserved room 10 of single first has been difficult to
All risk insurance demonstrate,proves leakproofness and anti-overcharge, therefore the reserved room 11 of relative volume lesser second is arranged, and has opened one 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, the stress deformation that matching hole 12 is used to that support ring flat-plate 7 is cooperated to occur avoids the tearing generated by internal stress or permanent curved
It is bent.
The matching hole 12 is round or oval 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 gallbladder, settable multiple solder joints, without with notch 13
Or other structures generate conflict, because being in the bottom of outer 2 inner wall of gallbladder, therefore facilitate processing, reduce manufacturing procedure.
Beneficial effects of the present invention: a kind of gas cylinder connection structure setting liner provided by the present invention and outer gallbladder, liner
With outer gallbladder front end using being rigidly connected, back end activity cooperation, in this way according to the principle expanded with heat and contract with cold, rear end avoids the heat of gas cylinder
Drawing crack of the swollen shrinkage to weld seam, the relative contact between the liner of rear end and outer gallbladder reduce nearly 2/3rds, heat transfer
Path reduce nearly half, structure is simple, stablizes, and has practicability and economy.
The basic principles, main features and advantages of the present invention have been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, those ordinary skill in the art's simply changes
It is all within protection scope of the present invention with replacement.
