Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a blade for an air-

More particularly, the present invention relates to a blade for an exhaust-type damper, and more particularly, to a blade for an exhaust-type damper, which is installed in a building to minimize a gap generated between the blades due to closing of the blades, To a damper for an exhaust separation type damper capable of preventing leakage.

Generally, in large buildings, ducts with air blowing are installed for air conditioning in buildings.

Such a duct is provided with a so-called damper for controlling or blocking the blowing amount for proper control of the fluid.

The original purpose of the duct described above is positive in terms of smooth air conditioning in the building, but it also functions as a fire path when a fire occurs, thus negatively affecting the duct.

Therefore, a fire damper is installed in the passage portion of the duct to block the fire when it occurs.

Such conventional conventional duct damper has been filed with Utility Model Registration No. 20-2000-0000421.

In the conventional duct damper, a plurality of blades are rotatably installed within the frame.

A rubber gasket is attached to the tip of the blade to maintain airtightness. The gasket is integrally formed with the blade.

A connecting rod is provided at an intermediate portion of the blade so that a plurality of blades can be integrally operated by the operation of a knob to be described later.

A cap for preventing air leakage is provided at both ends of the shaft 50, a leakage preventing member is attached to the lower side of the frame, and brackets are provided between the connecting rod and the blades to assemble them.

In addition, a control knob and an adjustment unit are provided at one side of the frame for external operation such as adjusting, shutting off or reopening the blowing amount of the damper.

The duct damper having such a structure operates air conditioning in a state where the inside of the frame is opened so that air can flow in the normal period, and when a fire occurs or if outside air is shut off when necessary, the control knob is operated, The blade is rotated by 90 degrees to block the inside of the frame.

However, in the conventional blade damper sealing structure of the conventional duct damper, as described above, a gasket made of rubber material is integrally formed at the tip of the blade to maintain airtightness, so that heat generated together with toxic smoke The gasket formed of rubber material is deformed or melted by heat, so that the function thereof, that is, the airtightness can not be maintained, the toxic smoke is only released, and another toxic smoke is generated while the gasket is melted.

In addition, as described above, in the conventional blade damper sealing structure of a duct damper, a rubber gasket is integrally formed at the tip of the blade to maintain airtightness, And the manufacturing cost is also increased.
