Abstract
Gas baffle door, comprise housing and be rotatably connected on the more blades on housing, the border of described blade is provided with shell fragment, the inner ring of described housing is provided with the diaphragm seal made of iron inwardly stretched out, described shell fragment is provided with the cavity that a circle elastomeric material is made, soft magnet is provided with in described cavity, when gas baffle door is closed, the appearance of cavity contacts with diaphragm seal and other shell fragment, magnet simultaneously in cavity attracts diaphragm seal and elastomeric material, ensure diaphragm seal and shell fragment, space is there is not between shell fragment and shell fragment, greatly strengthen sealing effectiveness like this.
Description
Technical field
The present invention relates to boiler afterheat and utilize technical field, especially relate to a kind of gas baffle door.
Background technology
Gas baffle door is the vitals during boiler afterheat utilizes, the very important index of gas baffle door be exactly in off position time sealing property.The sealing of sealing mainly between blade and between blade and frame inner wall of gas baffle door.Be all originally rely on blade surrounding to arrange flexure strip and doorframe inner ring arranges diaphragm seal, when blade is closed, flexure strip and flexure strip and form close contact between flexure strip and diaphragm seal, so just achieve sealing.But because the size of blade is very large, flexure strip and flexure strip and have some gaps unavoidably between flexure strip and diaphragm seal, this just have impact on sealing property.
In order to improve sealing property time baffle door is closed, the patent No.: cn200710164658.6 discloses a kind of baffle door with double-layer sealing structure, and this solves sealing problem to a certain extent.But or can not tackle the problem at its root.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide a kind of gas baffle door, greatly can improve the sealing property of baffle door.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals: gas baffle door, comprise housing and be rotatably connected on the more blades on housing, the border of described blade is provided with shell fragment, the inner ring of described housing is provided with the diaphragm seal made of iron inwardly stretched out, described shell fragment is provided with the cavity that a circle elastomeric material is made, soft magnet is provided with in described cavity, when gas baffle door is closed, the appearance of cavity contacts with diaphragm seal and other shell fragment, magnet simultaneously in cavity attracts diaphragm seal and elastomeric material, ensure diaphragm seal and shell fragment, space is there is not between shell fragment and shell fragment, greatly strengthen sealing effectiveness like this.
In technique scheme, preferably, described blade has certain thickness, and described shell fragment is arranged on the surrounding of former and later two end faces of described blade, and described diaphragm seal also has two-layer.
The present invention compared with prior art, there is following beneficial effect: when gas baffle door is closed, the appearance of cavity contacts with diaphragm seal and other shell fragment, magnet simultaneously in cavity attracts diaphragm seal and elastomeric material, ensure diaphragm seal and shell fragment, there is not space between shell fragment and shell fragment, greatly strengthen sealing effectiveness like this.
Accompanying drawing explanation
Fig. 1 is the schematic perspective view of the embodiment of the present invention.
Fig. 2 is the schematic diagram of blade and housing cooperation place.
Fig. 3 coordinates schematic diagram between blade with blade.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in further detail.
See Fig. 1 to 3: gas baffle door, the more blades 2 comprising housing 1 and be rotatably connected on housing 1, described blade 2 has certain thickness, and the two ends of blade are connected on described housing by rotating shaft 22.The border of described blade 2 is provided with shell fragment 21, and shell fragment 21 is arranged on the surrounding of former and later two end faces of described blade 2.
The inner ring of described housing 1 is provided with the made of iron two-layer diaphragm seal 11 inwardly stretched out, described shell fragment 21 is provided with the cavity 3 that a circle elastomeric material is made, be provided with soft magnet 4 in described cavity 3, the outer surface of described cavity 3 contacts with described diaphragm seal 11 and described shell fragment 21.
When gas baffle door is closed, the appearance of cavity contacts with diaphragm seal and other shell fragment, and the magnet simultaneously in cavity attracts diaphragm seal and elastomeric material, ensures diaphragm seal and shell fragment, there is not space between shell fragment and shell fragment, greatly strengthen sealing effectiveness like this.
Claims (2)
