Regulating flap adjusting mechanism for a draft regulator and a draft regulator equipped therewith

摘要

A control flap setting mechanism (1) for a draft regulator (2), in which a gas passage opening (43) is provided in a frame (41) which separates a first space area (47) from a second space area (49) by means of a control flap (39) is to be varied as a function of the pressure difference between the space regions (47, 49) separated by the frame (41), wherein the control flap actuating mechanism (1) is formed from a unit assembly which comprises at least the following components: a fixed to the frame (41) holder (3) with a pivot axis (17) defining the pivot bearing (9, 9), a for rotation about the pivot axis (17) on the pivot bearing (9, 9) held lever mechanism (4) an adjustment weight lever (27), a ballast weight lever (6) and a control lever (25) prepared for connection with the control flap (39) or connected to the control flap (39) that the control flap (39) in the intended installation state of the control flap actuating mechanism (1) in the tension regulator (2) between the gas passage opening (43) closing the closing position and a position of maximum release of the gas passage opening (43) about the pivot axis (17) is pivotable, wherein the Adjusting weight lever (27) has a setting weight (31, 31) adjustable thereto at different setting positions, and serves, depending on the position of the adjusting weight (31, 31) on the adjusting weight lever (27), the response of the regulating flap (39) with respect to pressure differences between the space regions (47, 49) separated by the frame (41), wherein the ballast weight lever (6) comprises or is formed by a ballast weight (13) and adapted to subject the control flap (39) to its closed position Moment on the lever mechanism (4) exercise.
