Single axis double baffle door

    The single axis double baffle door is one of the louver type flue gas baffle series, which adopts a double sealing structure of mechanical seal and compressed air seal to ensure 100% sealing effect. This product is made on the basis of introducing advanced foreign technology and drawing on the design and operation experience of similar domestic products.

    Single axis double baffle doors are mainly used in smoke and air duct systems to completely cut off the medium. They have full open and 100% full close functions, flexible actions, reliable operation, and can ensure that no medium leaks into the pipeline after the smoke baffle is closed. For ordinary media, carbon steel materials can be used, while for corrosive media, nickel based alloy materials can be used.

    Performance characteristics of single axis double baffle doors:

    1. The single axis double baffle door adopts a single axis driven double louver baffle structure, and a sealing chamber is designed in the middle of the double-layer blades to introduce sealing air. The sealing air above the flue gas pressure of 500Pa is passed into the baffle, forming a sealing air isolation layer between the double-layer baffles to block the passage of flue gas flow.

    2. The opening and closing time of the air door is ≤ 60S (can be selected according to user requirements).

    3. The external design has a connecting rod mechanism to synchronize the opening or closing of several blades.

    4. The design structure of the double louver baffle door is reasonable, with good blade rigidity and stable operation. The sealing types of the louver baffle blades are elastic sealing and air sealing.

    5. A sealed air inlet valve is designed and installed on the double baffle. After sealing air is introduced, the sealing efficiency of the baffle door is 100%.

    6. Driving method: pneumatic or electric.

    7. The driving device is usually installed in a direct connection with the air door.

    8. The electric device adopts electromechanical integrated products, with torque protection and limit devices, and can be remotely controlled for operation. The electric device also has manual and electric switching functions for use during installation, debugging, and maintenance.

    9. Connection method between damper and pipeline: flange sealing welding connection or flange bolt connection.

    10. The sealing fan and electric heater of the sealing air system can also be selected and supplied as a complete set by our company.
