Unterströmte Wehrklappe

摘要

The defence valve is pivotable around a horizontal rotary axis (22) arranged in the vicinity of its upper edge and above a stationary overflow threshold (14) and is loaded by a counter wt. (42) which has available the requisite closure and throttle force in respect of the upper flow side built-up water. The valve (20) in its closure position has a central inclination directed downstream and evolving from its under edge and to the extent of an acute angle (W), which is formed by a straight line running between its lower edge and the rotary axis (22) and a vertical evolving from the locating position.
