Description
Technical field
A kind of cryogenic storage tank explosion-protection equipment is the utility model is related to, belongs to deep cooling storing technology field.
Background technology
Current cryogenic storage tank generally use double-decker, that is, the inner pressurd vessel for storing cryogenic liquid are placed in shell, shell
Interlayer vacuum pumping between inner pressurd vessel.Due to cryogenic storage tank in use, if damaged leakage occurs in inner pressurd vessel, its
In cryogenic liquid can leak into interlayer, vacuum environment is destroyed, so that the pressure rise in interlayer space, causes Housing failure
Even there is the possibility of explosion, jeopardize life safety.
Therefore the structure for preventing that superpressure from bursting need to be installed additional on the shell, while the main quality index of deep freeze refrigeration plant is at present
Layer vacuum, the time that layer vacuum maintains is longer, is more conducive to the static evaporation rate index for meeting cryogenic storage tank, and prolong
The lossless time of repose of long cryogenic storage tank.Usually there is provided jacket gas safety relief on the shell of current this cryogenic storage tank
Explosion-protection equipment.But explosion-protection equipment enters a leak source of interlayer as ambient atmos again, therefore ensure that its sealing performance is closed very much
Whether key, sealing are reliably directly related to cryogenic storage tank layer vacuum parameter, are the key factors for ensureing product quality.At the same time
Its secure context will also consider explosion-protection equipment casualty accident caused by take-off part or explosion etc. when releasing.
The content of the invention
For above-mentioned shortcoming of the prior art, the utility model aims to provide a kind of cryogenic storage tank explosion-protection equipment,
It is novel in design, not only can guarantee that the sealing performance of whole cryogenic storage tank, but also can reach anti-explosion safety pressure release effect, reliable and stable.
To achieve these goals, the technical solution of the utility model：A kind of cryogenic storage tank explosion-protection equipment, it includes fixing
The device pedestal that is positioned on cryogenic storage tank shell and is connected with the vacuum interlayer of the cryogenic storage tank, be matched with the device pedestal
Gland on free port, the sealing ring on the gland and described device seat and cover at described device bottom
On seat and cause gland protection end socket of the inside, between pressure release between the protection end socket and described device base
Gap.
Further, the sealing ring is rectangular seal.
Further, it is described protection end socket include spherical arc shape section and with the integrally formed cylindrical section of spherical arc shape section, it is described
Cylindrical section is set with described device base with central axis and the cylindrical section internal diameter is more than described device base outside diameter, wherein, institute
Protection end socket is stated to be positioned on described device base by several fixing bolts.
Further, the gland include lid body corresponding with described device base free end face and with the lid sheet
Body by integral forming and with the matched guide part of described device base inner hole wall, wherein, have on described device base free end face
There is the seal groove of annular, the sealing ring is assemblied in the seal groove and upper end is higher than described device base free end face；Institute
The lid body for stating sealing ring and the gland forms static seal structure.
Further, described device base and the shell welding of the cryogenic storage tank are connected.
The beneficial effects of the utility model：Modern design, explosion-proof work(is formed by device pedestal, gland and protection end socket
Can, when cryogenic storage tank is during vacuumizing, sandwich shape is into vacuum, and external pressure can compress gland, in pressure
Effect lower seal realizes sealing effect, and isolation ambient atmos enter in interlayer；When internal container has leakage, the pressure of interlayer
When rise is higher than external atmosphere pressure, pressure is directly open-top gland, because there is the presence of protection end socket so that gland is in all the time
Protect in end socket and casualty accident occurs without fly bomb, and achieve the purpose that interlayer pressure of quickly releasing.In conclusion this is explosion-proof
Device not only can guarantee that the sealing performance of whole cryogenic storage tank, but also can reach anti-explosion safety pressure release effect, reliable and stable.
