Shot peening flow control valve and its method of use

A shot peening flow control valve for regulating a flow of ferromagnetic medium, the shot peening flow control valve comprising:

• a body defining a passage for transferring the ferromagnetic medium from a first end of the passage to a second end of the passage;
• at least one core layer arranged between the first end and the second end comprising at least one core line, wherein the at least one core layer is operable to provide a magnetic field at the passage;
• wherein the at least one core line comprises:
• a plurality of core sets connected in with each other, wherein one of the core sets is separated from another core set by a core set splitter;
• a plurality of shaft for connecting the plurality of core sets and the core set splitters together;
• and
• a cover enclosing the at least one core layer;
• wherein the cover comprises:
• an inlet flange for transferring the ferromagnetic medium from the first end;
• a first side frame and a second side disposed at sides of the at least one core layer respectively;
• a first central frame and a second central frame disposed at a front end and a rear end of the at least one core layer;
• a base diversion block disposed below the at least one core layer, the first and the second side frames, and the first and the second central frames of the cover;
• and
• a central extension guide for connecting the at least one core line with another core line in parallel configuration;
• wherein the central extension guide comprises a couple of triangular protrusions on both sides for one of the core sets located on either side of the central extension guide;
• wherein the couple of triangular protrusions are pointing towards a single slot;
• and
• wherein the central extension guide divides a passage between two core lines into two sub-passages.

A shot peening machine for projecting a ferromagnetic medium on a surface of at least one component, the shot peening machine comprising:

• a chamber for storing the ferromagnetic medium;
• a passage for transferring the ferromagnetic medium onto a surface of at least one component;
• a shot peening flow control that comprises:
• a body enclosing the passage for transferring the ferromagnetic medium from a first end of the passage to a second end of the passage, wherein the at least one component is placed at the second end of the passage;
• and
• at least one core set arranged between the first end and the second end, wherein the at least one core set comprises at least one magnetic unit, and the at least one magnetic unit is operable to provide a magnetic field at the passage and regulate a projection velocity of ferromagnetic medium on the surface of the at least one component, wherein the at least one magnetic unit comprises:
• a permanent magnet;
• a first electromagnet, a core of the first electromagnet is connected to a first end of the permanent magnet;
• and
• a second electromagnet, and a core of the second electromagnet is connected to a second end of the permanent magnet.

A method of regulating flow of a ferromagnetic medium, the method comprising:

• providing a magnetic field at a passage by at least one core set arranged between a first end and a second end of the passage, the at least one core set comprises at least one magnetic unit enclosed inside a housing of the at least one core set, the at least one magnetic unit comprises:
• a permanent magnet;
• a first electromagnet, a core of the first electromagnet is connected to a first end of the permanent magnet;
• and
• a second electromagnet, and a core of the second electromagnet is connected to a second end of the permanent magnet;
• wherein providing the magnetic field at the passage comprises:
• generating the magnetic field at the passage by the at least one magnetic unit;
• arresting the ferromagnetic medium by the magnetic field;
• transferring the ferromagnetic medium from the first end of the passage to the second end of the passage;
• and
• controlling the flow of ferromagnetic medium between the first end and the second end of the passage based on the magnetic field by regulating the magnetic field of the first electromagnet and the second electromagnet.
