Abstract
A kind of 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, the shell fragment of blade described in adjacent two panels is respectively arranged with projection and a circle groove that a circle flexible material makes, when described blade closes, described projection is inserted in described groove.Lug boss inserts in groove, and elastic deformation occurs, and relies on elasticity and groove inner wall to be formed and is close to, even if so blade assernbling manufacture has some errors, elastic deformation also can be relied on to make up, therefore substantially increase the sealing property of baffle door.
Description
Technical field
The utility model relates to boiler afterheat and utilizes technical field, especially relates 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: a kind of 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, the shell fragment of blade described in adjacent two panels is respectively arranged with projection and a circle groove that a circle flexible material makes, when described blade closes, described projection is inserted in described groove.Lug boss inserts in groove, and elastic deformation occurs, and relies on elasticity and groove inner wall to be formed and is close to, even if so blade assernbling manufacture has some errors, elastic deformation also can be relied on to make up, therefore substantially increase the sealing property of baffle door.
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.
In technique scheme, preferably, the cross section of described projection is trapezoidal.
The present invention compared with prior art, there is following beneficial effect: lug boss inserts in groove, there is elastic deformation, rely on elasticity and groove inner wall to be formed to be close to, even if so blade assernbling manufacture has some errors, also elastic deformation can be relied on to make up, therefore substantially increase the sealing property of baffle door.

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 5: a kind of gas baffle door, the more blades 2 comprising housing 1 and be rotatably connected on housing 1, the border of blade 2 is provided with shell fragment 21, and the two ends of blade 2 are rotatably connected on housing 1 by rotating shaft 22.Blade 2 has certain thickness, and shell fragment 21 is arranged on the surrounding of former and later two end faces of blade 2.The shell fragment 21 of adjacent two panels blade 2 is respectively arranged with projection 3 and a circle groove 4 that a circle flexible material makes, when blade 2 closes, protruding 3 insert in grooves 4.In the present embodiment, preferably, the cross section of projection 3 and groove 4 is trapezoidal, and this shape is conducive to increasing the sealing area between protruding when blade closes and groove, improves the efficiency of sealing.
The inner ring of housing 1 is provided with the two-layer diaphragm seal made of iron 11 inwardly stretched out, and the shell fragment 21 that diaphragm seal 11 is adjacent with diaphragm seal 11 is provided with the projection 3 and groove 4 that match.
Claims (3)
1. a 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, it is characterized in that: the shell fragment of blade described in adjacent two panels is respectively arranged with projection and a circle groove that a circle flexible material makes, when described blade closes, described projection is inserted in described groove.
