Description
Technical field
The utility model relates to a kind of connecting flanges, specifically provide a kind of dedicated connecting flange of blast furnace air supply system.
Background technique
Pass through flanged joint in blast furnace system between pipeline and between pipeline and expansion joint, as blast furnace air supply system uses
The increase of time, the flange connections in system are easy to produce gap, cause the position seriously to leak out, the hot wind of leakage is in high pressure
It easily burns under state on-site personnel, causes safety accident, such as deal with improperly, also supply air system will be caused to crumple or melt
Damage, leads to secondary damping down.At present it is to solve the problems, such as that wind is run in air-supply initial stage air port, can only reinforces checking before air-supply, once it send
Wind is run after wind, it is difficult to which wind position is run in band wind processing, influences furnace condition recovery process.
Therefore, how race wind position efficiently, reliably, is safely handled under blast furnace ventilation state, become people and urgently solve
Certainly the problem of.
Utility model content
In consideration of it, the purpose of this utility model is to provide a kind of dedicated connecting flanges of blast furnace air supply system, to solve nothing
Method efficiently, reliably, safely handles the problem of race wind position of flange connections in blast furnace system.
Technical solution provided by the utility model is: a kind of dedicated connecting flange of blast furnace air supply system, comprising: flange sheet
Body, side inverted U buckle and fastening bolt, wherein flange body includes first flange disk, second flange disk, gasket and connection spiral shell
Respectively with piping connection to be connect, gasket is set to the by connecting bolt presses for bolt, first flange disk and second flange disk
Between one ring flange and second flange disk, inverted U buckle in side is including upper plate, lower plate and is connected to upper plate and lower plate one
The connecting plate of side, forms card slot between upper plate and lower plate, for the end of sandwiched flange body, the middle part of upper plate is arranged
There is tapped through hole, fastening bolt is equipped in the tapped through hole.
It is preferred that the inside of the connecting plate is bonded with the periphery of upper plate and lower plate.
Further preferably, the gasket is to seal white steel pad.
Further preferably, the internal diameter of the tapped through hole of the middle part setting of upper plate is greater than 60mm.
Further preferably, the width of the card slot formed between upper plate and lower plate is 80~200mm.
Further preferably, inverted U buckle in side is that cast steel buckles.
The dedicated connecting flange of blast furnace air supply system provided by the utility model can be realized closely connecting to connecting line
Connect, when flange body is leaked out, by flange body leak out position end be located in side inverted U buckle card slot in, then
Fastening bolt is screwed, the position of leaking out of flange body can be squeezed, reach sealing effect.
Detailed description of the invention
With reference to the accompanying drawing and embodiment is described in further detail the utility model:
Fig. 1 is the structural schematic diagram of the dedicated connecting flange of blast furnace air supply system provided by the utility model.
Specific embodiment
The utility model is further explained below in conjunction with specific embodiment, but limitation is not originally practical
It is novel.
As shown in Figure 1, the utility model provides a kind of dedicated connecting flange of blast furnace air supply system, comprising: flange body
1, side inverted U buckle and fastening bolt 3, wherein flange body 1 includes first flange disk 11, second flange disk 12,13 and of gasket
Connect bolt (not shown), first flange disk 11 and second flange disk 12 respectively with piping connection to be connect, gasket 13
It is set between first flange disk 11 and second flange disk 12 by connecting bolt presses, the gasket 13 preferably seals white steel
Pad, side inverted U buckle include upper plate 21, lower plate 22 and the connecting plate 23 for being connected to 22 side of upper plate 21 and lower plate,
Card slot is formed between upper plate 21 and lower plate 22, for the end of sandwiched flange body 1, the middle part of upper plate 21 is provided with spiral shell
Line through-hole, fastening bolt are equipped in the tapped through hole.
The dedicated connecting flange of the blast furnace air supply system can be realized the close connection to connecting line, when flange body goes out
When now leaking out, the leak out end of position of flange body is located in the card slot of side inverted U buckle, then screws fastening bolt, it can
To squeeze the position of leaking out of flange body, reach sealing effect.
As the improvement of technical solution, the inside of the connecting plate 23 is bonded with the periphery of upper plate 21 and lower plate 22.
As the improvement of technical solution, the internal diameter of the tapped through hole of the middle part setting of upper plate 21 is greater than 60mm.
As the improvement of technical solution, the width of the card slot formed between upper plate 21 and lower plate 22 is 80~200mm.
As the improvement of technical solution, inverted U buckle in side is that cast steel buckles.
Specific embodiment of the present utility model is write according to progressive mode, and each embodiment party is highlighted
The difference of case, similar portion can be with cross-reference.
The embodiments of the present invention is elaborated above in conjunction with attached drawing, but the utility model is not limited to
Above embodiment can also not depart from the utility model within the knowledge of a person skilled in the art
Various changes can be made under the premise of objective.
