Description
Technical field
Fuel gas transportation pipeline technical field is the utility model is related to, particularly relates to a kind of metallic gas pipeline.
Background technology
Existing fuel gas transportation pipeline has rubber steel pipe, steel pipe, galvanized pipe, and steel pipe is mainly used in high-pressure gas conveying.With
The fast development of construction industry and productive consumption, the skyscraper in city is more and more.Skyscraper was completed in 5 years, sedimentation
Speed is maximum, and later sinking speed can be reduced gradually.Because gas pipeline has typically just installed initial stage in building completion,
Thus gas pipeline can be by following active force：1st, pultrusion active force caused by building settlement；2nd, structural weight per square meter is greatly to place through walls
Gas pipeline produce tangential stress.In the presence of both power, gas pipeline is easily deformed even gas leakage.How to improve existing
The structure of some fuel gas transportation pipelines, make gas pipeline while meet the requirement of high-storey and high-pressure gas conveying, be mesh
The preceding technical issues that need to address.
Utility model content
To solve above the deficiencies in the prior art, the utility model proposes a kind of high resiliency, tension splits, can meet height
The metallic gas pipeline that floor and high-pressure gas conveying require.
What the technical solution of the utility model was realized in：
A kind of metallic gas pipeline, formed by several piping units are end to end, piping unit includes：It is steel pipe, compound
Coating, front port and rear port, for composite coating coated on outside steel pipe, composite coating is externally provided with pipe collar, front port and rear port point
Not She Yu steel pipe both ends and symmetrical configuration, front port include the integrally formed first small-bore interface and the first heavy caliber and connect
Mouthful, rear port includes integrally formed second heavy caliber interface and the second small-bore interface, and the external diameter of the second small-bore interface is slightly
Less than the internal diameter of the first small-bore interface, the first small-bore interface, the first heavy caliber interface, the second heavy caliber interface and second are small
Bore interface is the bellows that spiral wire net filling neoprene is formed.
Preferably, anti-vibration protected packing ring is provided between composite coating and pipe collar.
Compared with prior art, the utility model is simple in construction, design science, has elasticity and tension fragility well
Energy, the requirement of high-storey and high-pressure gas can be met.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only
It is some embodiments of the utility model, for those of ordinary skill in the art, before creative labor is not paid
Put, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
In figure：1st, steel pipe；2nd, composite coating；21st, uvioresistant layer；22nd, articulamentum；23rd, anticorrosive coat；3rd, pipe collar；4th,
One small-bore interface；5th, the first heavy caliber interface；6th, the second heavy caliber interface；7th, the second small-bore interface.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
As shown in Figure 1：A kind of metallic gas pipeline, formed by several piping units are end to end, piping unit includes：
Steel pipe 1, composite coating 2, front port and rear port, for composite coating 2 coated on outside steel pipe 1, composite coating 2 is externally provided with pipe collar, preceding
Interface is respectively arranged on both ends and the symmetrical configuration of steel pipe 1 with rear port, and front port includes the integrally formed first small-bore interface 4
With the first heavy caliber interface 5, rear port includes integrally formed second heavy caliber interface, 6 and second small-bore interface 7, and second is small
The external diameter of bore interface 7 is slightly smaller than the internal diameter of the first small-bore interface 4, the first small-bore interface 4, the first heavy caliber interface 5,
Two heavy caliber interfaces 6 and the second small-bore interface 7 are the bellows that spiral wire net filling neoprene is formed.
Operation principle：During installation, pass through the length of flexible modulation steel pipe 1 so that front port or rear port are located exactly at
Place through walls, the second small-bore interface 7 is inserted in the first small-bore interface 4, and is fixed by fastener.Due to the first osculum
Footpath interface 4, the first heavy caliber interface 5, the second heavy caliber interface 6 and the second small-bore interface 7 are spiral wire net filling chlorine
The bellows that buna is formed, there is extraordinary elasticity and tension fragility, the company of also contributing to compared with common metal pipe
The compactness connect；Intensity is higher compared with General Purpose Rubber pipe, tension fragility is stronger, thus can both resist tangentially should for place through walls
Power, pultrusion power caused by high-level modeling can also be avoided to cause to deform to it.
The utility model is simple in construction, design science, has elasticity and tension fragility energy well, can meet high-storey
And the requirement of high-pressure gas.
As a kind of perferred technical scheme, another embodiment of the present utility model, set between composite coating 2 and pipe collar 3
There is anti-vibration protected packing ring.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc., the utility model should be included in
Protection domain within.
