The utility model provides a dustproof sleeve of the specialty when not having piping erection at present, prevent through forming airtight space that dust and sand from getting into, the spunyarn layer can prevent with the asbestos cement layer that toys such as mouse, bird are indoor from the mounting holes entering simultaneously, has reduced mounting hole shutoff technology and material, the practicality is big.
Description
Technical field
This utility model belongs to technical field of security and protection, particularly relates to the airtight sleeve pipe of rigidity of a kind of air defense basement.
Background technology
At present, known pipeline is when through walls installation, it is necessary to metope is porose just can be installed, the hole of metope
Built-in type and on-the-spot brill porthole two kinds are divided in hole.
Built-in type porthole is to build by laying bricks or stones in body of wall when masonry panel by built-in pipe, after brick-building art completes,
Generally body of wall must also the technique such as, powder lime levelling through sand-lime, Gypsum Fibrosum filling-in, roller coating coating,
To decoration Practical Completion, when air-conditioning is installed, some months at least, more than 1 year at most, through above work
After skill, a lot of sand and dust and granule in embedded hole, must be had.
The on-the-spot porthole bored, two end faces at wall can produce breakage, causes interior wall facade and external wall elevation dirty
Damage, meanwhile, in the new porthole bored, have substantial amounts of sand and dust and brickbat granule.
During Pipe installing, sand and dust or other solids or liquid enter in pipeline, can cause to pipeline
Blocking, serious situation can cause equipment whole system to damage, especially in air-conditioning duct is installed, in pipeline
Cleanliness factor particularly important.
In sum, it is necessary to design the airtight sleeve pipe of rigidity of a kind of air defense basement to make up drawbacks described above.
Utility model content
For solving drawbacks described above, the utility model proposes the airtight sleeve pipe of rigidity of a kind of air defense basement, its knot
Structure is simple, easy to use, and it does not interferes with wall decoration.
The technical solution of the utility model is achieved in that
The airtight sleeve pipe of rigidity of a kind of air defense basement, it includes steel thimble, steel pipe and back-up ring；Steel pipe is peripheral
It is interval with two baffle plates；It is peripheral that steel pipe socket is located at steel thimble, and steel thimble is arranged between two baffle plates, and
Steel thimble, steel pipe and two baffle plates surround a confined space；Asbestos cement layer it is filled with in confined space；Gear
Circle is connected in the middle part of steel pipe periphery, and it is between two baffle plates, and back-up ring is positioned at confined space；Steel bushing
Pipe periphery is provided with multiple airtight rib.
Wherein, back-up ring periphery is provided with spunyarn layer.
Wherein, steel thimble periphery is further provided with mounting flange.
Wherein, the width of spunyarn layer is 1/3rd of confined space width, and the asbestos water at spunyarn layer two ends
Mud layer width is 1/3rd of confined space width.
Wherein, back-up ring is welded on the periphery of steel pipe, and steel pipe, back-up ring and is all coated with zinc layers.
Compared with prior art, this utility model has the advantage that
This utility model solves the dust-proof sleeve pipe currently without specialty during Pipe installing, airtight by being formed
Space prevents sand and dust from entering, and spunyarn layer and asbestos cement layer can prevent the toy such as Mus, bird from installing hole simultaneously
Entering indoor, decrease installing hole plugging technology and material, practicality is big.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below by right
In embodiment or description of the prior art, the required accompanying drawing used is briefly described, it should be apparent that below,
Accompanying drawing in description is only embodiments more of the present utility model, for those of ordinary skill in the art,
On the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of the airtight sleeve pipe of rigidity of this utility model air defense basement.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, to the technical side in this utility model embodiment
Case is clearly and completely described, it is clear that described embodiment is only that this utility model part is real
Execute example rather than whole embodiments.Based on the embodiment in this utility model, ordinary skill people
The every other embodiment that member is obtained under not making creative work premise, broadly falls into this utility model
The scope of protection.
With reference to Fig. 1, the airtight sleeve pipe of rigidity 1 of a kind of air defense basement, it includes steel thimble 2, steel pipe 3 and
Back-up ring 4；Steel pipe 3 periphery is interval with two baffle plates 5；It is peripheral that steel pipe 3 is set in steel thimble 2, steel thimble
2 are arranged between two baffle plates 5, and steel thimble 2, steel pipe 3 and two baffle plates 5 surround a confined space；
Asbestos cement layer 6 it is filled with in confined space；Back-up ring 4 is connected in the middle part of steel pipe 3 periphery, and it is positioned at two gears
Between plate 5, and back-up ring 4 is positioned at confined space；Steel thimble 2 periphery is provided with multiple airtight rib 7.Steel thimble
2 peripheries are further provided with mounting flange 8, and this utility model mounting flange is for welding with baffle plate.
Wherein, back-up ring 4 periphery is provided with spunyarn layer 9.The setting of this utility model spunyarn layer, it is possible not only to prevent
Sealing shield ring gets rusty, moreover it is possible to prevent the toy such as Mus, bird from entering indoor from installing hole, decreases installing hole closure
