Description
Technical field
The present invention relates to closed air-valve technical fields, more particularly, to a kind of valve sealing structure and closed air-valve.
Background technique
It is usually provided with sealing structure on the valve block of existing closed air-valve, as shown in Figure 1, sealing structure includes spring leaf
11 and fixing sleeve 12, fixing sleeve is S type, and two sides are respectively set fluted, and the groove of side is used for indicator clip 11, another
The groove of side is for being inserted into valve block 13.In assembling process, the partial region of spring leaf 11 is inserted into the groove of fixing sleeve 12,
The outward bending of other part region；One end of valve block 13 is inserted into another groove of fixing sleeve 12, to pass through fixing sleeve
12 connect spring leaf 11 with valve block 13.Opening direction between spring leaf 11 and fixing sleeve is the valve block 13 away from its installation
Central axis.
But above-mentioned sealing structure can be only applied in suitable valve opening door (adjacent valve block rotation direction is identical), Bu Nengying
In split valve (adjacent valve block rotation direction is opposite), if above-mentioned sealing structure is applied in split valve, right
In valve opening door closing process, adjacent valve block can be inserted into the angle between spring leaf and fixing sleeve, and by spring leaf support to
Opposite direction can generate destruction to spring leaf, lose sealing effect.
Summary of the invention
The purpose of the present invention is to provide a kind of valve sealing structures, to improve the stable connection of sealing structure and blade
Property.
Valve sealing structure provided by the invention, comprising: elastic sealing element and fixing piece,
The elastic sealing element includes suit portion interconnected and sealing, and the suit portion is provided with the leaf with valve
The matched card slot of piece, there are angle, the opening sides of the angle between a part of at least described sealing and the suit portion
To opposite with the opening direction of the card slot；
The fixing piece has locating slot, and the suit portion of the elastic sealing element protrudes into the locating slot.
In the above-mentioned technical solutions, further, the sealing is straight panel, and the sealing position is in the suit portion
Side and to away from the suit portion direction extend.
In any of the above-described technical solution, further, the fixing piece has boss, and the boss is to the locating slot
Inside protrusion.

Mouthful towards right side.
In addition to this, the sealing of elastic sealing element can also be other structures shape, such as arc.
In a kind of specific embodiment of the present embodiment, fixing piece includes that relatively parallel the first positioning plate and second is determined
Position plate, and the third positioning plate being connected between the first positioning plate and the second positioning plate, third positioning plate are fixed perpendicular to first
Position plate and the second positioning plate.Locating slot is surrounded between first positioning plate, the second positioning plate and third positioning plate.In locating slot,
Right angle is formed between first positioning plate and third side, forms right angle between the second positioning plate and third positioning plate.In fixing piece
Outside is fillet between the first positioning plate and third positioning plate and between the second positioning plate and third positioning plate.
Corresponding, the suit portion of elastic sealing element includes the first side plate, the second side plate and third side plate, wherein the first side
Plate is parallel with the second side plate, and third side plate is connected between the first side plate and the second side plate, and perpendicular to the first side plate and second
Side plate.It is in straight between the first side plate and third side plate, between the second side plate and third side plate in the inside and outside in suit portion
Angle.It is arranged such, on the one hand, so that the contact area between suit portion and blade increases；On the other hand, so that suit portion and solid
The contact area for determining part increases.
After the suit portion of elastic sealing element is extend into the locating slot of fixing piece, the first side plate connects with the first positioning plate
Touching, the second side plate are contacted with the second positioning plate, and third side plate is contacted with third positioning plate.In a kind of preferred implementation of the present embodiment
In mode, elastic portion is connected to the end that the first side plate deviates from third side plate, and the length of the second positioning plate is greater than the second side plate
Length.The length of first positioning plate is less than or equal to the length of the first side plate.
To further increase the connective stability between valve sealing structure and blade, as shown in figure 4, fixing piece 52 has
Boss 522 compatible with the bayonet 21 of blade 20, boss 522 are protruded to the interior direction of locating slot.Pacify when by fixing piece 52
After being attached on blade 20, boss 522 is protruded to the inside of bayonet 21.So set, when valve sealing structure is installed to blade
After on 20, boss 522 is extend into the bayonet 21 of blade 20, so that the connective stability between fixing piece 52 and blade 20
Increase, since elastic sealing element is held between fixing piece 52 and blade 20, can further prevent elastic sealing element
Abjection.
Optionally, at least there is partial region and be set to the long region for second side plate of the second positioning plate in boss, even if
The partial region for obtaining boss is directly protruding into bayonet.
As shown in figure 4, further, a side end in suit portion is provided with concave inward structure 514, and concave inward structure 514 is to card
The interior direction of slot is bent.After suit portion is set on blade 20, concave inward structure is protruded into the bayonet 21 of blade 20.
In the above-mentioned technical solutions, further, concave inward structure is bonded with the partial region of boss.
In a kind of specific embodiment of the present embodiment, boss and concave inward structure can manufacture to be formed in the fabrication process.
Alternatively, in another specific embodiment of the present embodiment, boss and concave inward structure can be by valve seal knots
After structure is installed on blade, it is stamped and formed out in the valve sealing structure region ecto-entad opposite with the bayonet on blade.
The multiple boss of space set on fixing piece.
Valve sealing structure provided in this embodiment can be applied to volume damper, fire resisting damper, exhaust smoke valve, that is, can be applied to
Along open type valve, opposite opened valve can also be applied to.
