Description
Technical field
This utility model relates to flexible pipe field, is specifically related to a kind of nitrogen of resistance to liquid oxygen ultralow temperature metal hose.
Background technology
In the transmission of liquid oxygen nitrogen, can produce great low temperature environment, general metal hose holds can't stand this
The low temperature of sample, at low temperatures, the material of metal tube will become fragile, so can go out under using for a long time
The phenomenon now leaked, so needing to improve metal hose.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of nitrogen of resistance to liquid oxygen ultralow temperature metal hose.
For solving the problems referred to above, this utility model adopts the following technical scheme that a kind of nitrogen of resistance to liquid oxygen ultralow temperature gold
Belong to flexible pipe, including metal hose body, described metal hose body is provided with resistance to compression layer, insulating layer,
Protective layer；It is provided with vacuum layer between described insulating layer and resistance to compression layer；Described vacuum layer is provided with every
Temperature sponge；Described protective layer is stainless steel；Described resistance to compression layer is ultralow temperature steel matter.
Further, described metal hose body is provided with Wave spiral shape.
Further, described metal hose body is evenly arranged with some fixed mounts.
Further, the left side of described metal hose body is provided with switch valve.
Further, the right side of described metal hose body is provided with joint.
The effect of this utility model a kind of nitrogen of resistance to liquid oxygen ultralow temperature metal hose is: when coming into operation, metal
The resistance to compression layer of setting, insulating layer, protective layer on hookah bodies, the thermal insulation sponge in vacuum layer can be effectively
Isolation Cryogenic air, vacuum layer isolation low temperature, ultralow temperature steel matter can increase low temperature resistant degree, is using temperature
Degree undertissue Stability Analysis of Structures, has good weldability and processing forming, and metal hose body is provided with ripple
Wave helical form can make transmission direction malleable, and some fixed mounts can fix according to practical situation, switch
Valve can be with coutroi velocity, and joint can play the effect of connection, and its simple in construction is easy to use, operation letter
Single, resistance to ultralow temperature, crushing resistance is good, and anticorrosive degree is high.

Detailed description of the invention
Refering to the one nitrogen of the resistance to liquid oxygen ultralow temperature metal hose shown in Fig. 1 and Fig. 2, including metal hose body 1,
Resistance to compression layer 3, insulating layer 9, protective layer 4 it is provided with on described metal hose body 1；Described insulating layer
Vacuum layer 5 it is provided with between 9 and resistance to compression layer 3；Described vacuum layer 5 is provided with thermal insulation sponge 2；Described
Protective layer 4 be stainless steel；Described resistance to compression layer 3 is ultralow temperature steel matter.
As preferred technical scheme, described metal hose body 1 is provided with Wave spiral shape.
As preferred technical scheme, described metal hose body 1 is evenly arranged with some fixed mounts 6.
As preferred technical scheme, the left side of described metal hose body 1 is provided with switch valve 8.
As preferred technical scheme, the right side of described metal hose body 1 is provided with joint 7.
The effect of this utility model a kind of nitrogen of resistance to liquid oxygen ultralow temperature metal hose is: when coming into operation, metal
The resistance to compression layer of setting, insulating layer, protective layer on hookah bodies, the thermal insulation sponge in vacuum layer can be effectively
Isolation Cryogenic air, vacuum layer isolation low temperature, ultralow temperature steel matter can increase low temperature resistant degree, is using temperature
Degree undertissue Stability Analysis of Structures, has good weldability and processing forming, and metal hose body is provided with ripple
Wave helical form can make transmission direction malleable, and some fixed mounts can fix according to practical situation, switch
Valve can be with coutroi velocity, and joint can play the effect of connection, and its simple in construction is easy to use, operation letter
Single, resistance to ultralow temperature, crushing resistance is good, and anticorrosive degree is high.
The above, detailed description of the invention the most of the present utility model, but protection domain of the present utility model is not
It is confined to this, any change expected without creative work or replacement, all should contain at this utility model
Protection domain within.Therefore, the guarantor that protection domain of the present utility model should be limited with claims
The scope of protecting is as the criterion.
