Description
Technical field
This utility model is related to airduct valve technology field, particularly a kind of blade good suitable for airduct valve, rigidity.
Background technology
Airduct valve is commonly used in modern architecture, it is a large amount of be arranged on the giving of ventilation, air-conditioning and fire control smoke exhausting ventilating system,
On air return pipeline, at ordinary times in state is turned on and off, run into maintenance or fire can close when causing ambient temperature abnormal or
Open, play a part of to block air circulation.Wherein, inleakage is one important parameter of airduct valve, while and current wind
The important performance that pipe valve 3C certifications are investigated.The blade construction that airduct valve in the market is adopted, close rear blade and blade it
Between there is gap, poor sealing finds that inleakage is big, it is impossible to meet the requirement of 3C certifications in testing.Additionally, airduct valve disc
The rigidity of piece is not good enough, is easily deformed in the case of a high temperature, affects performance.
The content of the invention
The purpose of this utility model is that inleakage is big, there is potential safety hazard not after the closing existed for existing airduct valve
A kind of foot part, there is provided the good airduct valve disc piece of good airproof performance, rigidity.
This utility model is completed in the following way：A kind of airduct valve disc piece, the airduct valve disc piece include blade sheet
Body and reed, blade body are provided with flanging and reinforcement, and flanging is located at the end of blade body, and reinforcement is located at blade body
On, flanging can improve the rigidity of blade body with reinforcement；Reed is provided with a folding line, and on reed, the side of folding line is spring
The fixing end of piece, on reed the opposite side of folding line for reed free end, between the free end of the fixing end and reed of reed into
One angle, the fixing end of reed are fixed in blade body, and the free end of reed is contacted with adjacent blades, improve airduct valve
Sealing property.
In a kind of described airduct valve disc piece, described reinforcement is horizontally installed in blade body.
In a kind of described airduct valve disc piece, described blade body is provided with salient point or raised line, increases blade body
Rigidity.
In a kind of described airduct valve disc piece, described angular range is 100 ° to 170 °.
In a kind of described airduct valve disc piece, described reed is made using elastomeric material, and the fixing end of reed is adopted
Riveting, welding, the one kind in bonding are fixed in blade body.
In a kind of described airduct valve disc piece, described welding adopts spot welding or seam welding.
In a kind of described airduct valve disc piece, reinforcement in the blade body is domed or triangular structure.
In a kind of described airduct valve disc piece, the blade body is provided with two reinforcements, and two reinforcements are in the same direction
Or incorgruous setting.
Blade body of the present utility model is provided with reed made by elastomeric material, outside reed and adjacent blades or airduct valve
Shell phase is contacted, and for the sealing between blade and blade, blade and airduct valve shell, improves the performance of airduct valve；Blade body
Flanging is provided with, the rigidity of reinforced blade body prevents deformable blade at high temperature, affects airduct valve performance.Using this practicality
New airduct valve, its inleakage greatly reduce, and rigidity is good, disclosure satisfy that current detection, authentication requesting, improve safety
Energy.
This utility model compared with existing airduct valve disc piece, with rigidity good, good airproof performance the characteristics of.
