Description
Technical field
A kind of " u "-shaped water seal telescopic joint is the utility model is related to, belongs to Wet chimney technical field.
Background technology
In order to improve design level, both directly born the external loads such as wind and directly bear that flue gas acts on are realized not
Connatural load or effect are undertaken by different structure respectively, and meet the maintenance and maintenance requirement of different useful life, state
Inside and outside generally use armored concrete outer barrel bears wind load, earthquake and inner cylinder deadweight and the effect such as horizontal displacement, and uses
Dedicated for discharging the flue gas with high temperature and corrosiveness, the function of realizing inside and outside cylinder separates one or more inner cylinders, from
And generate telescopic or multitube smoke evacuation internal cylinder chimney and (when inner cylinder of discharging fume is 1, be referred to as " sleeve chimney "；When in smoke evacuation
When cylinder is 2 or more, it is referred to as " multitube chimney ").
Support or hang, it is necessary to be segmented because smoke evacuation inner cylinder is higher, to be connected between each section of inner cylinder by telescopic joint, to meet
The temperature deformation of inner cylinder and seal.Smoke exhaust barrel telescopic joint needs to bear higher temperature action and deep-etching effect, therefore its
It is more difficult on material selection.Particularly " Wet chimney " is (chimney during operation, because of the big condensation of smoke moisture or " wet desulphurization "
Flue gas carries the factors such as water droplet afterwards, causes smoke exhaust barrel inwall to form a large amount of acid solutions, and this chimney is referred to as " Wet chimney ") exist largely
Acid solution along barrel trickle, it is necessary to telescopic joint in addition to possessing larger deformability, meanwhile, have with greater need for telescopic joint excellent
Impervious and corrosion resistance, which increase the difficulty of telescopic joint selection.Because telescopic joint is during chimney is gone on a long journey, because damaging more
More difficulty is changed, this proposes very high requirement to the durability of telescopic joint again.
Generally way is to make row using the corrosion-resistant flexible material such as fluorubber shown in Fig. 1-1, Fig. 1-2, Fig. 1-3 at present
Chimney telescopic joint, its structure pass through the row of being fixed on of sealing ring fixation clip 2 for the both ends of variously-shaped flexible concertina sealing ring 1
On the sealing ring mounting flange 3 of cigarette inner cylinder 4, this telescopic joint has preferable corrosion resistance and deformability, but its cost
Higher, durability is bad, and changes difficult.
The content of the invention
The technical problems to be solved in the utility model is：Provide that a kind of cost is relatively low, sealing property is good and good endurance
" u "-shaped water seal telescopic joint, solve the problems, such as that Wet chimney ordinary telescopic section cost is high, poor durability.
In order to solve the above-mentioned technical problem, the technical solution of the utility model there is provided a kind of " u "-shaped water seal telescopic joint,
It is characterised in that it includes "u"-shaped groove and water seal telescopic end, the smoke evacuation inner cylinder of "u"-shaped groove connection one, "u"-shaped groove is interior to be provided with water sealing liquid
Body, water seal telescopic end top connect another smoke evacuation inner cylinder, liquid level of the water seal telescopic end bottom located at water seal liquid in "u"-shaped groove
Under, "u"-shaped groove includes "u"-shaped groove external annulus, "u"-shaped groove internal ring wall and "u"-shaped groove bottom land, "u"-shaped groove bottom land and its bottom
Inner cylinder of discharging fume connects.
Preferably, the described radius of "u"-shaped groove external annulus, the radius of water seal telescopic end, the radius of "u"-shaped groove internal ring wall
Reduce successively.
Preferably, the distance of described "u"-shaped groove bottom land and water seal telescopic end bottom is more than smoke evacuation inner cylinder in least favorable temperature
The maximum distortion spent under operating mode.
Preferably, the height of described "u"-shaped groove external annulus is more than the height of "u"-shaped groove internal ring wall.
Preferably, described "u"-shaped groove external annulus, "u"-shaped groove internal ring wall, "u"-shaped groove bottom land, the shape of water seal telescopic end
It is identical with the shape for inner cylinder of discharging fume.
Preferably, the horizontal cross-section of described "u"-shaped groove external annulus, water seal telescopic end, "u"-shaped groove internal ring wall is in concentric
It is circular.
Preferably, described "u"-shaped groove and the material of water seal telescopic end are resistant material, and resistant material can be glass
Glass steel, titanium alloy or Hastelloy.
Preferably, described "u"-shaped groove bottom land is arcuate bottom or flat.
The utility model reserves enough distances using "u"-shaped groove bottom land with water seal telescopic end end, to ensure inner cylinder of discharging fume
Freely stretch, while the sealing of whole telescopic joint is realized using water sealing liquid body inside "u"-shaped groove, ensures that flue gas will not be discharged into
Outside cigarette inner cylinder.Chimney flue gas itself during operation constantly carries water droplet and forms condensate liquid, and is trickled downwards along barrel,
So that water seal liquid is continuously supplemented, it is achieved thereby that telescopic joint is non-maintaining.The utility model have cost compared with
Low, sealing property is good and the advantages of good endurance, reaches service life identical with inner cylinder, water free of replacement is realized in design life
It is flat.
