    Shut-off baffle door


    Product description


    Shut-off baffle door is also known as shut-off door, duct baffle door or flue baffle door, often used in power plants or other industries in the smoke pipe, duct to do intercepting medium, the opening and closing Angle of the damper 90℃, it has two functions of fully open and fully closed, so that the system of a pipeline medium all flow or close.




    Shut-off baffle door is mainly composed of frame, blade, seal, spindle, bearing, shaft seal, crank linkage mechanism, actuator (optional part) and other parts.The frame is molded by steel plate, welded or cast, and the blade is molded or cast by steel plate. The streamlined blade section ensures minimal medium pressure loss.

    Special elastic sealing structure is provided between blades and blades and between blades and frames to ensure that the sealing rate before and after the blade is closed can reach above 99%, and the sealing rate can reach above 99.5% for special orders.The blade and spindle are connected by special fasteners. After the baffle damper is installed on the pipe, any part can be removed, and it can be easily repaired or replaced in the working state.The shaft neck adopts special sealing structure and special bearing, special sealing structure has good sealing performance, no leakage, high temperature resistance, special bearing has automatic centering and automatic compensation function, can automatically compensate the coaxiality deviation of the front and rear shaft, to ensure the closing baffle damper resistance is small, no jam, flexible rotation.

    Special bearing is provided on the crank connecting rod mechanism to ensure low transmission resistance. Double-arm heavy-duty crank connecting rod mechanism is adopted for the giant closing baffle door to ensure that the opening and closing action of the baffle damper is foolproof.Manual, electric or pneumatic actuators can be directly connected to the drive spindle or crank-rod mechanism to form a remote drive, actuators can also be customized by the user.


    Technical parameters


    1. Working pressure: generally <26000Pa, large specification shut-off damper or otherwise specified as special requirements;

    2, operating temperature: generally <350℃, higher than 350℃, otherwise indicated (high temperature damper up to 1100℃);

    3. Driving mode: manual, electric and pneumatic;

    4. Actuator (optional) : part of 90° Angle travel rotary, switch type;

    5. Sealing effect: >99%, otherwise indicated with special requirements (up to 99.5% above sealing effect)



    In the form of classification

    According to the shape can be divided into square closed baffle door and round closed baffle door;According to the driving mode can be divided into manual shut-off baffle door, electric shut-off baffle door and pneumatic shut-off baffle door;According to the manufacturing process can be divided into casting type shut-off baffle door and welding type shut-off baffle door;According to the material can be divided into cast iron closing baffle door, carbon steel closing baffle door, stainless steel closing baffle door and nickel base alloy closing baffle door.
