VALVE REMOTE CONTROL METHOD (VERSIONS) Russian patent published in 2009 - IPC F16K31/04 

FIELD: machine building.

SUBSTANCE: invention deals with methods of control over power-pressurised switch gear operating under time-varying thermal conditions within the framework of multi-phased technological processes and is aimed to provide for remote control of vacuum valves. The proposed remote control method envisages utilisation of multiple shutting-off device position stops and valve pressurisation effort amount restrictors. The position stops are remotely connected and the shutting-off device required position stops and pressurisation effort amount restrictors are operated.

EFFECT: enhanced valve pressurisation reliability, facilitated control over the shut off medium flow and reduced redundant deformation of the sealant element.
