Blocking device with flushing

摘要

The valve has seal surfaces (6, 7) provided at an inlet (4) between valve housings (1) and a closure element (2). One of the seal surfaces of the closure element is pivoted by rotation of the closure element and locks the inlet by resting against the seal surface of the valve housing in a lock position of the valve. Spacing of the seal surfaces to axles or a midpoint of the closure element is smaller than spacing of the axles and/or the midpoint to outer portions of a housing inner chamber to form a clearance connected with an outlet (5) in the lock position in a fluid-permeable manner. An independent claim is also included for a method for manufacturing a mold body.
