Abstract
A valve for regulating the flow of ferromagnetic peening materials, consisting of an arrangement of pole pieces, spacers, permanent magnets, and electrical coils. This arrangement uses an angular magnetic field to concentrate holding strength within the working gaps without sacrificing holding strength to the environment, increasing the valve's efficiency. Additionally, this valve covers a large range of flow rates by exchanging center bars and magnets of different sizes, without otherwise increasing the size of the valve.
Claims13
A valve for controlling a flow of media, the valve comprising:
- an opening configured to receive the flow of media, the opening defining a horizontal plane;
- a magnet configured to generate a magnetic field across the opening, the magnet positioned at a non-zero angle relative to the horizontal plane and having a central point along the horizontal plane;
- a coil configured to counter the generated magnetic field;
- and
- a controller configured to selectively engage the coil.
A valve for controlling a flow of media, the valve comprising:
- an opening, the opening defining a horizontal plane;
- a first pole piece positioned on an upper edge of the opening, the first pole piece comprising a first coil;
- a second pole piece positioned on a lower edge of the opening, the second pole piece comprising a second coil;
- a working gap defined by the first pole piece and the second pole piece;
- a first magnet coupled to the first and second pole pieces, the first magnet having a center in line with the horizontal plane defined by the opening;
- a second magnet coupled to the first and second pole pieces, the second magnet positioned opposite of the first magnet relative to the opening and having a center in line with the horizontal plane defined by the opening;
- a first set of spacers configured to position the first magnet at a first rotational angle relative to the horizontal plane;
- a second set of spacers configured to position the second magnet at a second rotational angle relative to the horizontal plane, the second rotational angle different from the first rotational angle;
- and
- a controller configured to switch the valve between a first state and a second state,
- wherein:
- in the first state, the first and second magnets generate a magnetic field across the working gap, and
- in the second state, the first and second coils counter the first and second magnets to negate the magnetic field across the working gap.
