Description
Technical field
This utility model relates to airduct valve technology field, a kind of blade being applicable to airduct valve, good seal performance.
Background technology
Airduct valve commonly uses in modern architecture, be arranged in a large number the giving of ventilation, air-conditioning and fire control smoke exhausting ventilating system,
On air return pipeline, at ordinary times in being turned on and off state, run into maintenance or fire can be closed when causing ambient temperature exception or
Open, play the effect blocking air circulation.Wherein, inleakage is one important parameter of airduct valve, is also current wind simultaneously
The important performance that pipe valve 3C certification is investigated.The blade construction that airduct valve in the market uses, close rear blade and blade it
Between there is gap, poor sealing, find that inleakage is big in testing, it is impossible to meet the requirement of 3C certification.
Summary of the invention
The purpose of this utility model is that inleakage is big, there is potential safety hazard not after the closedown existed for existing airduct valve
In place of foot, it is provided that the blade for airduct valve of a kind of good airproof performance.
This utility model completes in the following way: a kind of blade for airduct valve, and this is used for the leaf of airduct valve
Sheet includes blade body and reed, and reed is provided with a folding line, and on reed, the side of folding line is the fixing end of reed, on reed
The opposite side of folding line is the free end of reed, has angle between fixing end and the free end of reed of reed, fixing of reed
End is fixed in blade body.
Described a kind of in the blade of airduct valve, described angular range is 120 ° to 170 °.
Elastomeric material is used to make at described a kind of in the blade of airduct valve, described reed.
Described a kind of in the blade of airduct valve, the fixing end of described reed use riveting, welding, bonding in
A kind of.
In described a kind of in the blade of airduct valve, described welding employing spot welding or seam welding.
Described a kind of in the blade of airduct valve, described blade body is provided with some reinforcements.
Described a kind of in the blade of airduct valve, the reinforcement in described blade body is domed or triangle knot
Structure.
Described a kind of in the blade of airduct valve, described blade body is provided with two reinforcements, two reinforcements
Muscle is in the same direction or incorgruous setting.
Blade body of the present utility model is provided with the reed that elastomeric material is made, outside reed is with adjacent blades or airduct valve
Shell contacts, the sealing between blade and blade, blade and airduct valve shell, improves the performance of airduct valve.Use this reality
With novel airduct valve, its inleakage greatly reduces, it is possible to meet current detection, authentication requesting, improves security performance.
This utility model, compared with existing airduct valve disc sheet, has the spy that structure is ingenious, good airproof performance, security performance are high
Point.
