Description
Technical field
Fuel gas transportation pipeline technical field is the utility model is related to, particularly relates to a kind of compound fuel gas transportation pipeline.
Background technology
Existing fuel gas transportation pipeline has rubber PE pipes, steel pipe, galvanized pipe, and steel pipe is mainly used in high-pressure gas and conveyed, and one
As fuel gas transportation pipeline in cell all managed using rubber PE.With the fast development of construction industry and productive consumption, in city
Skyscraper is more and more.Skyscraper was completed in 5 years, and sinking speed is maximum, and later sinking speed can be reduced gradually.By
Typically just installed initial stage in building completion in gas pipeline, thus gas pipeline can be by following active force：1st, build
Pultrusion active force caused by sedimentation；2nd, structural weight per square meter produces tangential stress to the gas pipeline at place through walls greatly.In both power
Under effect, gas pipeline is easily deformed even gas leakage.The structure of existing fuel gas transportation pipeline how is improved, improves its tension and splits
Performance, elasticity is improved, gas pipeline is met the requirement of high-storey, is the current 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 is split, PE is managed and gold
Belong to the compound compound fuel gas transportation pipeline of pipe sleeve.
What the technical solution of the utility model was realized in：
A kind of compound fuel gas transportation pipeline, formed by several piping units are end to end, piping unit includes：PE
Pipe, metal pipe sleeve, front port and rear port, metal pipe sleeve are sheathed on outside PE pipes, and front port is respectively arranged on PE pipes with rear port
Both ends and symmetrical configuration, front port, which includes the integrally formed first small-bore interface and the first heavy caliber interface, rear port, to be included
Integrally formed second heavy caliber interface and the second small-bore interface, it is small-bore that the external diameter of the second small-bore interface is slightly smaller than first
The internal diameter of interface, the first small-bore interface, the first heavy caliber interface, the second heavy caliber interface and the second small-bore interface are spiral shell
Revolve the bellows-like structure of steel wire filling neoprene composition.
Preferably, in addition to located at metal pipe sleeve periphery 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 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, PE is managed；2nd, metal pipe sleeve；3rd, pipe collar；4th, the first small-bore interface；5th, the first heavy caliber interface；6th,
Two heavy caliber interfaces；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 compound fuel gas transportation pipeline, formed by several piping units are end to end, pipeline list
Member includes：PE pipes 1, metal pipe sleeve 2, front port and rear port, metal pipe sleeve 2 are sheathed on outside PE pipes 1, front port and rear port
The both ends of PE pipes 1 and symmetrical configuration are respectively arranged on, front port includes the integrally formed first small-bore heavy caliber of interface 4 and first
Interface 5, rear port include integrally formed second heavy caliber interface, 6 and second small-bore interface 7, the second small-bore interface 7
External diameter is slightly smaller than the internal diameter of the first small-bore interface 4, and the first small-bore interface 4, the first heavy caliber interface 5, the second heavy caliber connect
6 and second small-bore interface 7 of mouth is the bellows-like structure of spiral wire net filling neoprene composition.
Operation principle：During installation, pass through the length of flexible modulation PE pipes 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-like structure of buna composition, there is extraordinary elasticity and tension fragility compared with common metal pipe, additionally aid
Improve the compactness of connection；Intensity is higher compared with General Purpose Rubber pipe, tension fragility is stronger, thus can both resist place through walls
Tangential stress, 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
Requirement.
As a kind of perferred technical scheme, another embodiment of the present utility model, in addition to it is located at the periphery of metal pipe sleeve 2
Pipe collar 3.
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.
