METHOD OF SEALING AND DESIGN OF HIGH-PRESSURE ELECTROMAGNET VALVE Russian patent published in 2011 - IPC F16K25/00 F16J15/32 F16K31/02 

FIELD: construction.

SUBSTANCE: method to seal a high-pressure electromagnet valve includes its sealing in closed position by means of interaction of the seat circular edge with the conical surface of the stop valve under spring action at it and its opening by release of the specified spring under action of the electromagnet anchor and the seat opening with a stop valve. Additional sealing of the electromagnetic valve is carried out by interaction of two elastically resilient sealing circular ledges, which are serially arranged in front of the seat circular edge, with conical surface of the stop valve under action of high pressure of working fluid at the opposite side relative to the specified conical surface. There is an electromagnet valve design with above described sealing method.

EFFECT: improved reliability and resource of the electromagnetic valve operation.
