Description
Technical field
The utility model belongs to ultralow temperature piping temperature conduction field, and in particular to a kind of ultralow temperature piping crossing cabin sealing dress
It sets.
Background technique
As China's natural gas is using more and more, the development that the construction of liquefied natural gas (LNG) ship and LNG are transported,
It can more and more applications for meeting with super-low liquid pipeline crossing cabin.Since brittleness increases common steel material at low temperature, super
Under cryogenic conditions (being less than -100 DEG C), the common cold short phenomenon of steel material is serious, easily cracks under external force.
Traditional way is that the wall of large area or floor use low temperature material, and not only material consumption is big in this way, construction
Project is also more, considerably increases production cost.
Summary of the invention
Aiming at the problems existing in the prior art, the utility model provides a kind of ultralow temperature piping crossing cabin sealing device, energy
The low temperature of ultralow temperature piping is enough avoided to be directly transferred to steel wall or floor, to prevent the destruction of metal material, simultaneously also
Play crossing cabin part sealing function.
To achieve the above object, the utility model uses following technical scheme:
A kind of ultralow temperature piping crossing cabin sealing device, the device include ultra-low temperature pipe, casing, sealing plate and protection pipe, institute
It states casing and is set in ultra-low temperature pipe outer wall, spot welding is fixed between described sleeve pipe and ultra-low temperature pipe outer wall, is arranged in described sleeve pipe
There is sealing plate, be welded and fixed between described sleeve pipe outer wall and sealing plate, is equipped with protection pipe, the guarantor in the side of the sealing plate
It is welded and fixed between one end and sealing plate of pillar, is welded and fixed between the other end and partition of protection pipe.
The shape of the sealing plate is circular ring shape.
Between the sealing plate, protection pipe and partition be equipped with deep floor, three sides of the deep floor respectively with
It is welded and fixed between sealing plate, protection pipe and partition.
The shape of the deep floor is right-angled trapezium.
Described sleeve pipe, sealing plate, protection pipe, deep floor are 316L stainless steel.
The ultra-low temperature pipe, casing, sealing plate and protection pipe are coaxially disposed.
The partition is steel wall or steel floor.
Compared with prior art, the utility model has the following beneficial effects:
The utility model can be applied to the fixation and sealing that ultra-low temperature pipe penetrates steel room wall or steel floor, can
To be applied to the pipeline crossing cabin of super-low liquid, such as liquefied natural gas (- 163 DEG C), liquid nitrogen (- 196 DEG C) etc., the utility model
Device carries out isolating seal or fixation to ultralow temperature piping and the steel wall penetrated or floor, can be applicable in variant caliber
The fixation and sealing of ultralow temperature piping crossing cabin, simple installation is easy to disassemble, reduces cost and easy construction.
The all parts of the crossing cabin sealing device can be pre-installed in advance, as casing can be welded on ultra-low temperature pipe in advance
On, other all parts directly assemble in advance in factory, and scene is mounted directly crossing cabin sealing device, simple and efficient to handle.As
Structure its temperature around low temperature piping is reduced to environment temperature, and material should use low-temperature steel.The crossing cabin sealing device
Material is corrosion-resistant and low temperature resistant material Stainless steel 316 L, is transmitted to conventional steel bulkhead or floor later by the device
Temperature will be within the allowable temperature of material.
