What is a double-sealed single-axis circular baffle door?

The double-sealed single-axis circular baffle door is mainly used for intercepting or adjusting the flow of medium in the air ducts and flues of power plants, and can also be used for air ducts and flues in other industries. The flue gas damper door generally requires 100% tightness under the action of pressure difference. The flue gas damper door usually adopts a double-layer shutter type. In addition to the sealing element on each damper door, sealing gas is usually passed into the cavity of the two-layer flue gas damper door to further improve the flue gas damper. The tightness of the panel door. The double-sealed single-axis circular baffle door can make all the media in a certain pipeline of the system circulate/cut or the media flow changes with control. For the small diameter double-sealed single-axis circular baffle door, it has the functions of intercepting and adjusting the medium flow. For the large diameter circular damper, its linear adjustability is not obvious, and its intercepting function is mainly used.
