Description
Technical field
The utility model relates to baffle board door of flue technical field more particularly to a kind of zero leakage gas baffle doors.
Background technique
Continuous improvement with country to environmental requirement, the discharges such as electric power, heating, steel, cement, metallurgy, chemical industry are a large amount of
The industry of flue gas, it is further stringent to flue gas emission index.In general, gas baffle door is installed in the flue of boiler system to close
Flue gas that is disconnected, opening, shunt and adjust flue, due to containing more harmful components in flue gas, to the antiseptic property of baffle door
And sealing performance requirement is further stringent.
Gas baffle door generallys use louver type damper door, and baffle door can be divided into uniaxial single gear according to its blade shape
Plate, uniaxial double baffles, twin shaft list baffle, the double baffles of twin shaft.Traditional uniaxial single baffle only has single layer blade, using elastic sheet metal
Overlap joint cooperation sealing is formed with metal plate, forms sealing cavity among sealing surface；To guarantee leakproofness, need to lead into seal chamber
Enter sealing air, consumes larger, sealing higher cost.Uniaxial double baffles use twi-tier blade parallel construction, and centre is passed through dry, dry
Net hot-air blocks flue gas, but logical hot air device will be always maintained at normal power-up during operation, cause human and material resources
And energy waste.
Summary of the invention
To solve the above problems, the utility model provides a kind of zero leakage gas baffle door, it is mountable horizontal flue,
At bypass flue, vertical gas pass, flue gas can be effectively completely cut off in exhaust gases passes or flue gas is allowed to circulate, there is extraordinary sealing
Property and operational safety.
The utility model provides a kind of zero leakage gas baffle door, including frame and blade, and the frame is equipped with bearing
Seat and shaft sealer, the bearing block connecting rod or compression bar, the compression bar are equipped with pressing plate, and the blade passes through the drawing
Bar is set on the frame, is surrounded by sealing on the inside of the frame, and the vane stress applies pressure to the frame inside four
In the sealing in week, the frame side is equipped with transmission actuator, and the transmission actuator connect with the pull rod, drives the leaf
Piece level is moved to the left or right, and is played the role of opening or closing baffle door, is equipped with locking above the frame other side and holds
Row device, the locking actuator are connect with the compression bar, when the blade is in close state, the locking actuator driven
Compression bar rotation, the pressing plate on the compression bar rotates with it, holds out against the blade, and the vane stress applies pressure to the frame
In the sealing of inside surrounding, sealing function is played, blow valve port, the blow valve port connection are equipped with below the frame other side
Compressed air is for purging the base of frame dust stratification, ash hole discharge of the dust stratification from side below the frame, it is ensured that described
The tight type and leakproofness that blade is connected with the frame, play the purpose of flue gas zero leakage.
Preferably, the frame is rectangle, and the blade is the rectangle with the adaptation.
Preferably, the pressing plate is that disloyalty is round.
Preferably, described to be sealed into ceramic fibre packing.
The utility model has well solved that baffle door leakproofness caused by local deformation, dust stratification is poor, Wu Faguan
Tight problem, eliminates security risk, has the characteristics that simple structure, good seal performance, repair and maintenance are convenient.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
Fig. 2 is A-A view of pressing plate schematic diagram in Fig. 1.
Specific embodiment
The utility model is described in further detail with specific embodiment with reference to the accompanying drawing：As shown in Figure 1, a kind of
Zero leakage gas baffle door, including frame 1 and blade 2, the frame 1 are equipped with bearing block 3 and shaft sealer 4, the axis
3 connecting rod 5 of seat or compression bar 6 are held, the compression bar is equipped with several pressing plates 61, and the blade 2 is set to institute by the pull rod 5
It states on frame 1, is surrounded by sealing 11 on the inside of the frame 1,2 stress of blade applies pressure to the 1 inside surrounding of frame
In sealing 11,1 side of frame is equipped with transmission actuator 7, the transmission actuator 7 connect with the pull rod 5, drive described in
Blade level is moved to the left or right, and locking actuator 8, the locking actuator 8 and institute are equipped with above 1 other side of frame
The connection of compression bar 6 is stated, blow valve port 9 is equipped with below 1 other side of frame, the blow valve port 9 connects compressed air for purging institute
1 bottom dust stratification of frame is stated, the 1 lower section side of frame is equipped with ash hole 10.
The frame 1 is rectangle, and the blade 2 is the rectangle being adapted to the frame 1.
The pressing plate 61 is that disloyalty is round.
The sealing 11 is ceramic fibre packing.
7 driving blade 2 of transmission actuator of present apparatus setting is moved to the left or right, and is played and is opened or closed baffle door
Effect.
The locking actuator 8 of present apparatus setting drives compression bar 6 to rotate, and the pressing plate 61 on compression bar 6 rotates with it, holds out against blade
