Abstract
A multi-blade dosing valve comprising the following elements: a valve body provided with a central opening; a plurality of shafts, each provided with a respective blade, which extend transversely to the central opening; the blades being able to close, at least partially, the central opening; a motor unit which causes the opening/closing of the blades; and vibrators to set in vibration the shafts and the blades. The multi-blade dosing valve comprises an independent vibrator for each shaft.
Claims13
A multi-blade dosing valve comprising the following elements:
- a valve body provided with a central opening crossed, in actual use, by the pulverulent or granular material which is discharged from a hopper into a distribution duct;
- a plurality of shafts, each provided with a respective blade, which extend transversely to said central opening;
- said blades being able to close, at least partially, said central opening;
- an actuating system, which, by rotating said plurality of shafts, causes the opening/closing of said blades;
- and
- a vibrator device to set in vibration said shafts and said blades;
- multi-blade dosing valve characterized in that it comprises an independent vibrator device for each shaft;
- and
- vibration damping means, said damping means being associated with each shaft.

- a vibrator device to set in vibration said shafts and said blades;
- multi-blade dosing valve characterized in that it comprises an independent vibrator device for each shaft;
- and
- substantially equal upper half-shell and lower half-shell;
- each half-shell comprising a respective truncated pyramidal part to which respective connecting means are fixed;
- wherein a respective plurality of openings is arranged on two respective opposite and parallel edges of the truncated pyramidal parts;
- the perimeter of each opening being formed by a broken line having at least some curved sides.
