ELECTRO-MAGNET VALVE Russian patent published in 2010 - IPC F16K31/02 

FIELD: machine building.

SUBSTANCE: electro-magnet valve consists of case with seat, of shut-off element, and of electro-magnet drive with magnetic conductor. The shut-off element has a non-metallic circular packing. The magnetic conductor consists of upper and lower flanges, of a sealing dividing tube, of a core and a return spring. The sealing dividing tube consists of three links. Two of these links are made out of ferromagnetic material. The third link is located between them and is made out of low magnet material. The lower link of the dividing tube is made complex. The cavity of the dividing tube with the core is sealed relative to working medium by means of a washer and radial circular non-metallic packing. The washer and packing are arranged between components of the lower link. The end non-metallic circular packing is installed in the seat. The shut-off element is equipped with a rod. The rod is tied with the core of the electro-magnet drive. The shut-off component is made as a tube with wedge-shaped edges. Middle diametre of wedge-shaped edges is equal to internal diametre of the lower link of the dividing tube.

EFFECT: design of valve reliably operating in viscous mediums.
