2, each support plate one end and support sleeve boxing connect, and the outside of the other end is also welded with supporting pad, supporting pad with
Shell lower head inner wall welding, so that forced area is expanded, so that the fixation of gas tank bottom is relatively reliable.
3, the interior lining ring of bottom fixing structure is glass reinforced plastic steel ring, and heat-insulating property is excellent and intensity is only second to metal, material
It is small by external force deformation, it can guarantee the complete firm fixation between gas tank liner and shell, and it is small to leak heat.
4, installation space and process operability are comprehensively considered in structure design, and " convex " type is arranged in fixing axle external circumferential
Lining ring in structure elongates the axial width of interior lining ring as far as possible, reduces its radial dimension, and interior lining ring small end axial width is
30mm, interior lining ring radial thickness 50mm, wherein radial big end thickness 40mm, radial small end thickness 10mm, interior lining ring heat transfer distances
For maximum value 50mm, heat transfer contact area is minimum value, and low temperature is held time length, cryogenic property guarantees degree height, so that gas tank
Use more safety and economy.
5, interior lining ring is N layers, and N is the natural number more than or equal to 2.Interior lining ring uses multilayered structure, is bearing vertical low temperature
When gas tank weight, weight in the case where proof strength, can be reduced by liner material in reasonably selecting as far as possible.
