Description
Technical field
The utility model is related to a kind of metal bends, more precisely, being a kind of novel aviation vacuum metal elbow.
Background technology
In pipe-line system, elbow is the pipe fitting for changing pipeline direction.Angularly divide, have 45 ° and 90 ° 180 ° three kinds most often
, further include 60 ° of other equal improper angle elbows according further to requirement of engineering.The material of elbow has cast iron, stainless steel, conjunction
Jin Gang, malleable cast iron, carbon steel, non-ferrous metal and plastics etc..The mode being connect with pipe has direct welding, flanged joint, hot melt
Connection, electric smelting connection, threaded connection and bayonet joint etc..Aviation vacuum metal elbow is one kind of elbow, but general at present
Weaker all over the aviation vacuum metal elbow entirety thermal insulation used, elbow is easily interfered by ambient temperature, influences the steady of internal flow
It is qualitative.
Utility model content
The utility model is mainly the technical problem solved present in the prior art, to provide a kind of novel aviation vacuum
Metal bends.
The above-mentioned technical problem of the utility model is mainly to be addressed by following technical proposals：
A kind of novel aviation vacuum metal elbow, including a bend pipe, the outer wall of bend pipe is socketed a collet, the collet
For multilayered structure, collet ecto-entad is followed successively by stainless steel layer, ceramic layer, silica aerogel layer and polyethylene layer, one end weldering of bend pipe
Pair of lamina pipe is connect, bimetallic tube is hollow structure, and the end of bimetallic tube connects a connection-peg, and connection-peg is equipped with a serrated end, curved
The other end of pipe welds a reduced pipe, and a sleeve is welded in the end of reduced pipe.
As the utility model preferred embodiment, the bend pipe is copper pipe.
As the utility model preferred embodiment, the ceramic layer is soft ceramics.
The novel aviation vacuum metal elbow of the utility model is provided with a bend pipe on the body, and one has been socketed on bend pipe
A collet, collet are multistory steel structure, and the influence that collet can be by external temperature to tube body is reduced to minimum, bend pipe
On also welded a bimetallic tube, bimetallic tube, which is hollow structure, can also play heat-blocking action, and then effectively promote internal flow
Stability.
Description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, other drawings may also be obtained based on these drawings.
Fig. 1 is the dimensional structure diagram of the novel aviation vacuum metal elbow of the utility model；
Fig. 2 is the novel aviation vacuum metal elbow collet multilayered structure schematic diagram of the utility model.
Specific implementation mode
The preferred embodiment of the utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear to be made to the scope of protection of the utility model
Define.
As shown in Figs. 1-2, a kind of novel aviation vacuum metal elbow 1 a, including bend pipe 10, the outer wall socket one of bend pipe 10
Collet 11, the collet 11 be multilayered structure, 11 ecto-entad of collet be followed successively by stainless steel layer 111, ceramic layer 112,
Silica aerogel layer 113 and polyethylene layer 114, one end welding pair of lamina pipe 20 of bend pipe 10, bimetallic tube 20 is hollow structure, bimetallic tube 20
End connect a connection-peg 21, connection-peg 21 is equipped with a serrated end 22, and the other end of bend pipe 10 welds a reduced pipe 30, different
Weld a sleeve 31 in the end of diameter pipe 30.
It is further improved as to the utility model, the bend pipe 10 is copper pipe.
It is further improved as to the utility model, the ceramic layer 112 is soft ceramics.
The novel aviation vacuum metal elbow of the utility model is provided with a bend pipe on the body, and one has been socketed on bend pipe
A collet, collet are multistory steel structure, and the influence that collet can be by external temperature to tube body is reduced to minimum, bend pipe
On also welded a bimetallic tube, bimetallic tube, which is hollow structure, can also play heat-blocking action, and then effectively promote internal flow
Stability.
The mentality of designing for only illustrating the utility model in one embodiment above, in the case where system allows,
The utility model can be extended to while external more function modules, to extend its function to greatest extent.
Above description is only a specific implementation of the present invention, but the scope of protection of the utility model is not limited to
In this, any change or replacement expected without creative work should be covered within the scope of the utility model.
Therefore, the scope of protection of the utility model should be determined by the scope of protection defined in the claims.
