バタフライ弁付内外気切換ダンパ。 It is supported via a rotating shaft extending approximately horizontally in an inside/outside air switching box that has an outside air intake on the top and an inside air intake on the side, and has holes at predetermined locations. In the inside/outside air switching damper, the butterfly valve is supported via an eccentric shaft with respect to the outside air switching damper, and when the inside/outside air switching damper is in a position to close the outside air intake port, the butterfly valve is supported by the eccentric shaft. The large area section divided by the shaft is located on the opposite side of the rotation axis, and the tip thereof rides on the edge of the hole, and the tip of the small area section is formed in such a size that it slips under the edge of the hole. and the butterfly valve is characterized in that the inside air intake port is provided with a lattice that comes into contact with the tip of the small area portion of the butterfly valve when the inside/outside air switching damper is in a position where the inside air intake port is closed. Internal/external air switching damper with valve.
