DEVICE FOR DETECTING THE SIMULTANEOUS CLOSING OF TWO MOBILE ORGANS AND ITS APPLICATION TO A FLAP-STOP SYSTEM

摘要

P The invention relates to a detector (7) of a determined position reached simultaneously by two movable members, in particular the complete closure of two flaps (31b, 32b) of a valve for fire protection system. The detector comprises a mini or a microswitch (8) provided with a push button (81) and two lateral pushers constituted by a rod (71, 72) whose first ends are connected by a transverse lever (90). The latter presses the push button (81) via an adjustment screw (91). Springs (75, 76), mounted on the rods (71, 72) exert repulsive forces so that they drive the lever (90) and the latter pushes the push button (81). The flaps (31b, 32b) repel the rods (71, 72) when they are closed. Two stops are provided (92, 93) limiting the stroke of the lever (90). So that the latter fully releases the push button (81) and there is detection of the closing of the flaps (31b, 32b), it is necessary that the lever (90) comes to bear on the two stops (92, 93 ) at a time. /P
