Description
Technical field
The invention belongs to boiler flue systems technology field, and in particular to a kind of flue damper device.
Background technology
In boiler flue system, the effect of air door is to change the flow or trend of boiler flue, cut-off boiler flue with
Contact between boiler accessory machinery.In the prior art, boiler flue air door structure is generally venetian blind type, the flue damper of the form
It is poor to there is closure state sealing, door opening ratio controls the shortcomings that inaccurate.
The Patent No. 2015204631332 that State Intellectual Property Office authorizes, it is public in title " a kind of flue damper device "
A kind of flue damper device is opened.In the device, the inside both sides edge of air door framework is respectively equipped with flashboard chute, air door lock
For plate slide fit in flashboard chute, the bottom of air door framework is provided with the air door connectivity port to match with ventilating duct, the top of air door framework
Portion is respectively equipped with motor and spiral lift, and wherein motor drives spiral lift, the drive of spiral lift by driving belt
Moving axis is connected by sprocket wheel with driving chain, and the screw rod of spiral lift is connected to the top of air door flashboard through air door framework.
Its shortcoming is that for air door flashboard in closure, with still having gap at frame edge, sealing is poor for it, and flue gas is easily excessive.
The content of the invention
The task of the present invention is to provide a kind of simple, practical and favorable sealing property flue damper device.
The task of the present invention is done in such a way that characterized in that, sealed compartment（4）Rear end is fixed with flue outlet（2）, it is preceding
The fixed chimney intake in end（1）, the chimney intake（1）It is inclined end face to go deep into sealed compartment one end, chimney intake（1）Outer wall gos deep into
Ears link is fixed with peak in sealed compartment（1-1）, link（8-1）One end passes through axle and the ears link
（1-1）Be hinged, one end is fixed on closure（8）Edge, the sealed compartment（4）Top is fixed with air cylinder support（5）, cylinder
（6）Upper end and air cylinder support（5）It is be hinged, tailpiece of the piston rod and connecting rod（7）Threaded one end connects, the connecting rod（7）Through close
The batten down and other end is hingeably secured to closure（8）Home position, the closure（8）It is brought into close contact in chimney intake（1）
Inclined end face.The sealed compartment（4）For cube structure, top sets access hole close to chimney intake side（3）.The flue
Import（1）, flue outlet（2）For circular pipe, the closure（8）For circular steel plate, diameter is more than chimney intake（1）Tilt
The diameter in face.
The present invention has the following effects that：The technical program realizes the opening of air door by the folding of cylinder control closure
With closure.Simple in construction, practical, favorable sealing property.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；Fig. 2 is the side view of the present invention.
1. chimney intake, 1-1. ears links, 2. flue outlets, 3. access holes, 4. sealed compartments, 5. air cylinder supports, 6.
Cylinder, 7. connecting rods, 8. closures, 8-1. links.
Embodiment
Embodiments of the invention are described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning to end
Same or similar label represents same or similar element or the element with same or like function.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to for explaining the present invention, and is not considered as limiting the invention.
Embodiment is described in detail in the technical program combination the figures above, and as shown in Fig. 1 Fig. 2, the rear end of sealed compartment 4 is fixed with cigarette
Chimney intake 1 is fixed in road outlet 2, front end, and it is inclined end face that the chimney intake 1, which gos deep into sealed compartment one end, the outer wall of chimney intake 1
Go deep at the peak in sealed compartment being fixed with ears link 1-1, link 8-1 one end passes through axle and the ears link
1-1 is hinged, and one end is fixed on the edge of closure 8, and the top of sealed compartment 4 is fixed with air cylinder support 5, the upper end of cylinder 6 and gas
Jar support 5 is be hinged, and tailpiece of the piston rod is connected with the threaded one end of connecting rod 7, and the connecting rod 7 is hinged through sealed compartment and the other end
The home position of closure 8 is fixed on, the closure 8 is brought into close contact in the inclined end face of chimney intake 1.
The sealed compartment 4 is cube structure, and top sets access hole 3 close to chimney intake side, worker can be facilitated to examine
Repair operation.The chimney intake 1, flue outlet 2 are circular pipe, and the closure 8 is circular steel plate, and diameter enters more than flue
The diameter of 1 inclined plane of mouth.
The device is before work, it is necessary to which 3 complete closing seam of access hole, chimney intake 1, flue outlet 2 need to weld with flue
Connect fixation.When need to separate between boiler flue and boiler accessory machinery when contacting, cylinder 6 works, and piston rod extension, drives connection
Bar 7 takes closure 8 and is brought into close contact in the inclined end face of chimney intake 1.When need not separate boiler flue and boiler accessory machinery it
Between contact when, the piston rod on cylinder 6 is retracted, and closure 8 is lifted as rotating shaft using the jointed shaft on ears link 1-1, made
The flue gas entered by chimney intake 1 can freely and smoothly enter flue outlet 2.Gone wrong inside flue damper device
When, master worker can open access hole 3 and be overhauled, convenient and swift.
In the present invention, unless otherwise clearly defined and limited, the art such as term " installation ", " connected ", " connection ", " fixation "
Language should be interpreted broadly, for example, it may be fixedly connected or be detachably connected, or integrally connected, can be two members
Connection inside part.For those skilled in the art, above-mentioned term can be understood the present invention's as the case may be
Concrete meaning.
