Abstract:

A valve with permanent magnet(s) and electro-magnet coils magnetically coupled to the permanent magnet(s). The valve is positioned below an inlet for receiving media. The amount of media flow may be regulated by controlling the current to the coils for partial or full flow. With no power applied to the electro-magnet coils, the media flow is inhibited. Application of a current to the electro-magnet coils will block the flux in the pole pieces rendering the working gap free of magnetic flux and thus allowing media to freely flow. As it is used, the media may become magnetized, altering the flow properties and causing magnetized media to bridge across the working gap. A magnetic sensor detects the amount of flux in the working gap to provide a signal to a control system. The signal allows closed loop control of the coils as media becomes magnetized, allowing consistent flow properties during use.

Abstract:

A shot peening flow rate control that is useful for non-ferrous shot peening media. The control has an inlet for receiving media and an orifice through which the media may pass that is in communication with the inlet. A valve selectively blocks the orifice. The valve has a spindle that is guided for axial movement between an open and closed position. The closed position blocks the orifice and the open position places the spindle spaced from the orifice to allow media to flow through the orifice. A flow sensor has a deflectable member that extends into a flow path of media leaving the orifice. In response to increasing or decreasing flow of the media through the flow path the deflectable member will deflect more or less. A sensing device measures the deflection in the deflectable member and generates an electrical signal that varies in response to deflection in the deflectable member.
