DAMPER TYPE FLOW CONTROL APPARATUS

摘要

The present invention relates to a flow control apparatus which can control a forced draft flow of a fan, and more particularly, to a flow control apparatus which can not only precisely control an opening/closing angle but also improve operating reliability. According to the present invention, a flow control apparatus includes a flange (10) defining the outward appearance, a plurality of vanes (20) rotatably installed on the flange (10) to open and close the flange (10), a driving means (40,50) for rotating the vanes (20), and a gear assembly (30) for transferring a turning force of the driving means (40, 50) to the vanes (20).
