Description
Technical field
The utility model relates to a kind of supporting sleeve ring structure, particularly relates to a kind of supporting sleeve ring structure being applied to low-temperature pressure container.
Background technique
Along with the rapid economic development of society, sharply strengthen as gas usage such as rock gas, helium, oxygen, at present for above-mentioned gas, there is multiple storage and receive container, wherein, low-temperature pressure container, by low-temperature storage liquid gas, is compared, the storage volume of its compression is larger, and safer, especially as automobile-used LNG gas cylinder, use amount rises year by year.Low-temperature pressure container use principle carrys out storing liquefied gas by low temperature, so thermal insulation property just seems particularly important, low-temperature pressure container all adopts the sandwich structure of inside and outside two courages, inner bag adopts support or 2 supporting structures usually at 8, and reduce heat trnasfer except relying on laminated vacuum layer, be secondly exactly control the heat trnasfer in supporting structure.
In prior art, generally adopt full-metallic to design for supporting structure, the heat trnasfer of metal is very high, can have a strong impact on the static evaporation rate of low-temperature pressure container.
Model utility content
The purpose of this utility model is to solve above-mentioned technical problem, proposes the supporting sleeve ring structure being applied to low-temperature pressure container.
The purpose of this utility model, will be achieved by the following technical programs:
1. be applied to the supporting sleeve ring structure of low-temperature pressure container, described low-temperature pressure container has inner bag and outer courage, is provided with supporting mechanism between described inner bag and outer courage,
It is characterized in that: the outer wall of described inner bag is provided with back shaft, described supporting mechanism comprises supporting frame and is fixedly installed on the collar group of supporting frame, described collar group comprises first collar and the 3rd collar that fix attaching, and second collar of sliding installation in first collar and the 3rd collar, described back shaft to be connected in collar group and to be fixedly connected with second collar.
Preferably, described second collar is epoxy glass steel collar.
Preferably, described second collar sliding installation in the 3rd collar and the end of second collar be limited in first collar towards the ring wall of the 3rd collar and the 3rd collar towards the end face of first collar between.
Preferably, between the end of described second collar and the ring wall of first collar, there is 2mm gap.
Preferably, the end sidewalls of described second collar and the internal ring wall of first collar have gap.
Preferably, between described first collar and the 3rd collar for being welded and fixed.
The beneficial effects of the utility model are mainly reflected in:
1. second collar be connected with back shaft is epoxy glass steel collar, and the thermal conductivity of fiber glass epoxy, well below stainless thermal conductivity, effectively reduces the heat trnasfer between inner bag and the external world;
2. second collar has linear displacement first and the 3rd in the collar, and back shaft and second collar servo-actuated, when inner bag expands with heat and contract with cold, back shaft carrys out adjusted position by the displacement of second collar, avoids the impact of tensile stress or pressure stress;
3. leave gap between second collar and first collar, decrease direct heat trnasfer between the two, meanwhile, in first collar and the 3rd collar welding process, can not produce second collar and damage.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model is applied to the supporting sleeve ring structure of low-temperature pressure container.
Fig. 2 is the structural representation that the utility model is applied to collar group in the supporting sleeve ring structure of low-temperature pressure container.
Embodiment
The utility model provides a kind of supporting sleeve ring structure being applied to low-temperature pressure container, reduces inner bag and extraneous heat trnasfer, prevents inner bag from expanding with heat and contract with cold to low-temperature pressure container generation damage simultaneously.
As depicted in figs. 1 and 2, be applied to the supporting sleeve ring structure of low-temperature pressure container, low-temperature pressure container has inner bag 1 and outer courage 2, supporting mechanism 3 is provided with between inner bag 1 and outer courage 2, the outer wall of inner bag 1 is provided with back shaft 4, supporting mechanism 3 comprises supporting frame 5 and is fixedly installed on the collar group 6 of supporting frame 5, collar group 6 comprises first collar 61 and the 3rd collar 63 that fix attaching, and second collar 61 of sliding installation in first collar 61 and the 3rd collar 63, back shaft 4 to be connected in collar group 6 and to be fixedly connected with second collar 62.Back shaft and second collar servo-actuated, when inner bag expands with heat and contract with cold, back shaft regulates self-position by the displacement of second collar, avoids the impact of tensile stress or pressure stress.
Wherein, the second collar 62 sliding installation in the 3rd collar 63 and the end 621 of second collar 62 be limited in first collar 61 towards the ring wall 611 of the 3rd collar 63 and the 3rd collar 63 towards the end face 631 of first collar 61 between.Second collar 62 is epoxy glass steel collar, and the thermal conductivity of fiber glass epoxy, well below stainless thermal conductivity, effectively reduces the heat trnasfer between inner bag and the external world.The endoporus that second collar 62 is prolonging the 3rd collar slides, and the end face that the end of second collar is subject to the ring wall of first collar and the 3rd collar is spacing, and back shaft and second collar servo-actuated, when inner bag expands with heat and contract with cold, back shaft regulates self-position by the displacement of second collar, avoids the impact of tensile stress or pressure stress.
In addition, between the end 621 of second collar 62 and the ring wall 611 of first collar 61, there is 2mm gap.End 621 sidewall of second collar 62 and the internal ring wall 612 of first collar 61 have gap 613.Gap decreases the direct heat trnasfer between first collar 61 and second collar 62, meanwhile, in first collar 61 and the 3rd collar 63 welding process, can not produce damage second collar 62.
Finally, between first collar 61 and the 3rd collar 63 for being welded and fixed.
The utility model still has numerous embodiments, all employing equivalents or equivalent transformation and all technological schemes formed, and all drops within protection domain of the present utility model.
