Double sealed single axis circular baffle door
Double sealed single axis circular baffle doors are mainly used for intercepting flow or regulating medium flow in power plant air ducts and flues, and can also be used for air ducts and flues in other industries. The smoke baffle door generally requires 100% tightness under the action of pressure difference. The smoke baffle door is usually a double-layer louver type. In addition to sealing elements on each layer of baffle door, sealing gas is usually introduced into the cavity of the two layers of smoke baffle door to further improve the sealing performance of the smoke baffle door. The double sealed single axis circular baffle door can allow all the medium in a certain pipeline of the system to flow/cut off, or the medium flow rate to change with control. For double sealed single axis circular baffle doors with smaller diameters, they have two functions: interception and adjustment of medium flow rate. For circular air doors with larger diameters, their linear adjustability is not very obvious, and their interception function is mainly used.
