Description
Technical field
The utility model is related to technology of gas pipeline field, more particularly to a kind of double-wall hose.
Background technology
Currently, gas hose is broadly divided into two classes, one is daily life gas hoses, are 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 comprising inner and outer tubes, and inner and outer tubes generally use welding procedure is tied
It closes, this process is more complicated, 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 generate destruction；And inner and outer tubes are not easy to remove, and it is whole just to continue to make when inner tube or the leakage of outer tube one of both
With, thus replacement cost is higher, is unfavorable for combustion gas and promotes the use of on a large scale.
Utility model content
And, the utility model provides a kind of double-wall hose in view of the above-mentioned defects in the prior art,
Realization gas-fired equipment is flexible coupling with gas supply pipeline, and gas-fired equipment is reduced in the process of running to combustion gas by double-wall hose
Supply line stress, pipeline liquidates when reducing in-site installation, reduces pipeline maintenance cost and the potential of safety accident generation can
Energy.
Technical solution adopted by the utility model to solve its technical problems is：A kind of double-wall hose, including inner tube and outer
Pipe, inner tube be inscribed in outer tube and with the outer coaxial tube heart, annular chamber is formed between inner tube and outer tube, which is characterized in that in described
Pipe and outer tube are respectively provided at least one section of bellows, and said inner tube and outer tube both ends are described by straight tube and double-walled flanged joint
Double-walled flange is equipped with ventilation hole, and the ventilation hole is set between inner and outer tubes, is convenient for double-wall hose inner and outer tubes
Gas leakage amount is detected.
As the optimal technical scheme of the utility model, said inner tube is equipped with one section of inner tube bellows, on the outer tube
Equipped with one section of outer tube bellows, said inner tube bellows is identical as outer tube Bellows Length and end face is aligned.
As the optimal technical scheme of the utility model, several support portions, the support portion are additionally provided in the annular chamber
For flexible support.
As the optimal technical scheme of the utility model, the ventilation hole is described axially through double-walled flange body
Ventilation hole is uniformly distributed along double-walled circumference of flange direction.
The utility model has the beneficial effects that：The prior art is compared, a kind of double-wall hose of the utility model has larger
Amount of deflection, industrial circle use scope is wide, and installation, convenient disassembly are easily changed, maintenance cost is small, safe, can fill up market
Upper LNG hoses notch can greatly save installation and debugging work by this double-wall hose, reduce cryogenic pipe and bring frostbite injury latent
Possible.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
In figure：1, 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, support portion.
Specific implementation mode
It elaborates below in conjunction with the accompanying drawings to specific embodiment of the present utility model, furthers elucidate the utility model
The advantages of and outstanding contributions compared with the existing technology, it is possible to understand that, following embodiments is only preferable to the utility model
The detailed description of embodiment should not be construed as any restrictions to technical solutions of the utility model.
As shown in Figure 1, a kind of double-wall hose, including inner tube 1 and outer tube 2, it is interior and same with outer tube 2 that inner tube 1 is inscribed in outer tube 2
Axle center forms annular chamber between inner tube 1 and outer tube 2, several support portions 4 are additionally provided in annular chamber, and support portion 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 as 21 length of outer tube bellows and end face is aligned, and inner tube 1 and 2 both ends of outer tube pass through inner pipe straight respectively
12 and outer tube straight tube 22 and double-walled flange 3 weld, double-walled flange 3 is equipped with ventilation hole 31, and ventilation hole 31 is set to 1 He of inner tube
Between outer tube 2, gas leakage amount is detected convenient for 1 pipe and outer tube 2 in double-wall hose.
In the present embodiment, ventilation hole 31 is axially through 3 ontology of double-walled flange, and ventilation hole 31 is along double-walled flange 3
Circumferencial direction is uniformly distributed.
When installation, first by double-wall hose by straight tube welding on double-walled flange, then pass through lower 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 use
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 safety accident generation it is potentially possible.
