Abstract

Blast valve comprising a first disc (10), non-pivotally arranged in a cylindrical housing (2) and having an off-centrally positioned through hole (11), a second disc (12) arranged in contact with the first disc (10) and having a correspondingly positioned through hole (13), the second disc (12) being pivotally arranged in the housing (2) and attached to one end of a spindle (14) extending through the wall of the housing (2), the housing (2) having an inlet (13) for blast powder and an outlet (4) for connection to an air conduit (6), the inlet (3) and outlet (4) being in mutual alignment and in alignment with the through holes (11) and (13), respectively, wherein the spindle (14) is connected to a proportionally controlled actuator means (18,18') which actuates the spindle (14) for relative rotation of the discs (10;12), said actuator means (18,18') being remotely controlled electrically by a control means (22) for the continuous adjustment of the blending ratio of air and blast powder.
