Description
Technical field
The utility model belongs to double-wall pipe field, and more specifically to a kind of continuous vacuum is insulated double-wall pipe.
Background technique
There are ultralow temperature pipeline in the storage of ship LNG host fuel and feed system (design temperature is -165 DEG C).Mesh
The preceding pipeline for the temperature grade, is all made of stainless steel tube outsourcing heat preservation insulating materials to carry out the conveying of cryogenic media, this
There are problems for method, such as are difficult to detect to the leakage of pipeline；There are the manifold volumes of outsourcing insulation excessively to expand, and is easy old
Change, damage.
Some also uses double-wall pipe on ship, and using is that multistage double-wall pipe is mutually spliced by flange
At, but when working on ship, it is in Long-term Vibration and moving condition, flange connections are easily displaced and are broken, while double
Wall pipe internal-external temperature difference is larger, causes stroke inside and outside double-wall pipe different, has movement poor in the axial direction, furthermore the junction of flange
It connects inner and outer tubes here, is unable to reach insulation effect, thermal insulation property is poor.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of using double-wall pipe, and double-wall pipe is in continuity, i.e.,
Cavity between inner tube and outer tube be it is continuous, reduce heat loss caused by inner tube is contacted with outer tube, at the same inner tube and outer tube it
Between can opposite sliding, the continuous vacuum insulation double-wall pipe to prolong the service life.
To achieve the above object, the utility model provides following technical solution: a kind of continuous vacuum insulation double-wall pipe,
Including several segments inner tube and several segments outer tube, the outer tube sleeve is welded between the two neighboring inner tube on the outside of inner tube, described
Huff pipe is welded between two neighboring outer tube, be provided between said inner tube and outer tube several groups insulation sliding support and it is several
The fixed support of group insulation.
There are three insulation sliding support described in every group further and the fixed support of insulation are at least circumferentially evenly arranged.
The further insulation sliding support includes support base and sliding block, and the support base is fixed on the outside of inner tube, institute
It states sliding block to be fixed on support base, the sliding block is slidably connected with outer tube.
Elastomer is provided between the further sliding block and support base.
The further fixed support of the insulation includes the supporter for being fixedly connected with inner and outer tubes.
Crossing cabin part is provided on the outside of the further outer tube.
Vacuumizing joint, pressure detecting connector and safety blasting piece are provided on the further outer tube.
Compared with prior art, the utility model has the beneficial effects that using double-wall pipe (i.e. double-deck pipeline) to low temperature
It is conveyed when medium, the cavity between whole double-wall pipe all the way is vacuumized as a whole, is thoroughly avoided uncontrollable
Leakage, avoids inner tube from directly contacting with outer tube, is more easier to be supervised in real time when avoiding the aged deterioration of thermal insulation material, and monitoring
Control, while insulation sliding support of the inner tube between outer tube can make to have at a distance from relative movement between inner tube and outer tube, with solution
Certainly vibration and temperature difference bring inner and outer tubes relative movement distance are poor, while being insulated fixed support and can be avoided inner tube and outer
Pipe relative movement distance is excessive to be caused to be in contact in elbow inner tube with outer tube.

Specific embodiment
It is described further referring to figs. 1 to embodiment of the Fig. 3 to the utility model continuous vacuum insulation double-wall pipe.
A kind of continuous vacuum is insulated double-wall pipe, including several segments inner tube 1 and several segments outer tube 2, including 2 sets of the outer tube
On the outside of pipe 1, is welded between the two neighboring inner tube 1, be welded with Huff pipe 9, said inner tube between the two neighboring outer tube 2
Several groups insulation sliding support 7 and the fixed support 8 of several groups insulation are provided between 1 and outer tube 2.
As shown in Figure 1, double-wall pipe includes the weldering at elbow 3 and at straight line, while to guarantee inner tube 1 in actual installation
It connects smoothly, certain space is reserved between adjacent two outer tube 2, after the completion of the welding of inner tube 1, welded two outer tubes 2 using Huff pipe 9
Together, integral installation difficulty is reduced, integrally saves and is attached using flange, avoid inner tube 1 and outer tube 2 direct in flange
Heat loss caused by contacting, while the vacuum cavity that internal shape is integral, the double-wall pipe of vacuum state can be in inner tube 1
Medium plays good heat insulation effect, while being convenient for subsequent real time monitoring；Secondly in shipping work, ship vibrates, interior
Pipe 1 and outer tube 2 have the trend of relative movement, and insulation sliding support 7 can make inner tube 1 carry out certain phase with outer tube 2 at this time
To sliding, while also adapting to the relative displacement that inner and outer pipes 2 generate due to there are different temperature expansion/shrinkages；And it is insulated
