Specific implementation mode
With reference to specific embodiments and the drawings, the present invention is described in further detail.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of high-pressure hydrogen storage cylinder, including：Liner 1, there are two bottle necks for setting on liner 1
2, one is big bottle neck, another is small bottle neck, is wound with fibre reinforced layer 11 and glass successively on the outer surface of liner 1
Fibrous protective layer 12 is both provided with the sealing hole 13 coaxial with bottle neck 1 in the inside of each bottle neck 2, further includes：It is threaded onto bottle neck 2
On plug 3 that bottle neck 2 is sealed, plug 3 can be the common plug for being served only for sealing, can also be stifled with valve
Head；The sealing axis 31 coaxial with plug 3 is provided on the inner end of plug 3, sealing axis 31 can be inserted into after plug 3 screws in bottle neck 2
Into sealing hole 13, it is provided with the annular groove 32 arranged around sealing axis 31 on sealing axis 31, is covered in annular groove 32
The material of baffle ring 34 equipped with the first O-ring seals 33 and positioned at 33 outside of the first O-ring seals, baffle ring 34 is polyether-ether-ketone,
First O-ring seals 33 can carry out axial seal, gear by blocking the gap between sealing axis 31 and sealing hole 13 to bottle neck 2
Circle 34 can stop the first O-ring seals 33 so that the first O-ring seals 33 will not be squeezed out annular groove 32 by high pressure hydrogen and
Lead to seal failure.Above-mentioned axial seal energy better seal bottle neck 2, and due to being provided with baffle ring 34 so that it is axial close
It seals relatively reliable.
