DAMPER WITH CURVED EXTENSION PLATES FOR WIDE RANGE FLOW CONTROL |
摘要 |
<p>A damper for fluid flow control has a curved extension plate positioned with respect to the circular path defined by the end of a pivotal damper blade to provide close control of the effective open area over a wide range of damper openings. The curved extension plate has a straight portion connected tangentially to one end of an arcuate portion. The arcuate portion of the extension plate approximates the shape of a theoretically ideal curve such that in cooperation with pivoting of the damper blade, the free flow area increases approximately linear with damper opening to provide a linear response between damper blade position and fluid flow rate.</p> |
