Description
Technical field
The present invention relates to technology of gas pipeline field, more particularly to a kind of double-wall hose.
Background technology
At present, gas hose is broadly divided into two classes, and one kind is daily life gas hose, it is mainly used in building dress
The fields such as decorations, sanitary ware, universal pipe diameter are less than 60.3mm；Another is industrial fuel gas hose, in the prior art
Industrial combustion gas hose use double-wall pipe, it includes inner and outer tubes, and inner and outer tubes generally use welding procedure is tied
Close, this technique is complex, and required equipment is more, and since industrial fuel gas equipment pipe bore is larger, gas-fired equipment exists
Have certain vibrations in operational process, fuel gas pipeline is rigidly connected with gas-fired equipment, can cause fuel gas pipeline by stress deformation into
And produce destruction；It is overall just to continue to make when inner tube or the leakage of outer tube one of both and inner and outer tubes are not easy to remove
With, thus replacement cost is higher, is unfavorable for combustion gas and promotes the use of on a large scale.
The content of the invention
In view of the above-mentioned defects in the prior art and existing technical problem, the present invention provides a kind of double-wall hose, realize
Gas-fired equipment is flexible coupling with gas supply pipeline, and gas-fired equipment is reduced in the process of running to gas supply by double-wall hose
Pipeline stress, pipeline liquidates when reducing in-site installation, reduce pipeline maintenance cost and security incident occur it is potentially possible.
The technical solution adopted by the present invention to solve the technical problems is：A kind of double-wall hose, including inner and outer tubes, it is interior
Pipe be inscribed in outer tube and with the outer coaxial tube heart, annular chamber is formed between inner tube and outer tube, it is characterised in that said inner tube and outer
Pipe is respectively provided with least one section of bellows, and said inner tube and outer tube both ends pass through straight tube and double-walled flanged joint, the double-walled method
Orchid is equipped with ventilation hole, and the ventilation hole is arranged between inner and outer tubes, easy to double-wall hose inner and outer tubes to combustion gas
Amount of leakage detects.
As the preferred technical solution of the present invention, said inner tube is equipped with one section of inner tube bellows, and the outer tube is equipped with
One section of outer tube bellows, said inner tube bellows is identical with outer tube Bellows Length and end face is alignd.
As the preferred technical solution of the present invention, some supporting parts are additionally provided with the annular chamber, the supporting part is soft
Property stent.
As the preferred technical solution of the present invention, the ventilation hole is axially through double-walled flange body, the ventilation
Aperture is uniformly distributed along double-walled circumference of flange direction.
The beneficial effects of the invention are as follows：The prior art is contrasted, a kind of double-wall hose of the invention, has compared with large deflection, work
Industry field use scope is wide, and installation, convenient disassembly, are easily changed, maintenance cost is small, safe, and it is soft to fill up in the market LNG
Pipe notch, can greatly save installation and debugging by this double-wall hose and work, and reduce cryogenic pipe and bring frostbite injury potentially possible.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention.
In figure：1st, inner tube, 11, inner tube bellows, 12, inner pipe straight, 2, outer tube, 21, outer tube bellows, 22, outer tube it is straight
Pipe, 3, double-walled flange, 31, ventilation hole, 4, supporting part.
Embodiment
Elaborate below in conjunction with the accompanying drawings to the embodiment of the present invention, the advantages of the present invention is furture elucidated and
Relative to the outstanding contributions of the prior art, it is possible to understand that, following embodiments is only to the detailed of preferred embodiment of the present invention
Describe in detail bright, should not be construed as any restrictions to technical solution of the present invention.
As shown in Figure 1, a kind of double-wall hose, including inner tube 1 and outer tube 2, inner tube 1 are inscribed in outer tube 2 and same with outer tube 2
Axle center, forms annular chamber between inner tube 1 and outer tube 2, some supporting parts 4 are additionally provided with annular chamber, and supporting part 4 is flexible support.
In the present embodiment, inner tube 1 is equipped with one section of inner tube bellows 11, and outer tube 2 is equipped with one section of outer tube bellows 21,
Inner tube bellows 11 is identical with 21 length of outer tube bellows and end face is alignd, and inner tube 1 and 2 both ends of outer tube pass through inner pipe straight respectively
12 and outer tube straight tube 22 welded with double-walled flange 3, double-walled flange 3 is equipped with ventilation hole 31, and ventilation hole 31 is arranged on 1 He of inner tube
Between outer tube 2, gas leakage amount is detected easy to 1 pipe and outer tube 2 in double-wall hose.
In the present embodiment, ventilation hole 31 is axially through 3 body of double-walled flange, and ventilation hole 31 is along double-walled flange 3
Circumferencial direction is uniformly distributed.
During installation, first by double-wall hose by straight tube welding on double-walled flange, then pass through next of double-walled flanged joint
Double-wall hose, realizes combustion gas being flexible coupling using equipment and gas supply pipeline, passes through double-walled gas hose and reduces combustion gas and uses
For equipment in the process of running to gas supply pipeline stress, pipeline centering when reducing in-site installation, reduces pipeline maintenance cost, together
When also reduce security incident generation it is potentially possible.
