HIGH-PRESSURE VALVE WITH TELESCOPIC PISTON Russian patent published in 2020 - IPC F16K15/18 F16K17/08 

FIELD: machine building.

SUBSTANCE: group of inventions relates to a valve for supplying gas under high pressure, as well as to a fire extinguishing system with a valve. Valve for gas supplied under pressure includes housing with inlet, outlet hole and channel, which connects inlet hole with outlet hole and which contains seat. Valve comprises a sliding piston with two opposite surfaces, made with possibility of coming into contact with a socket for closing the channel. Valve is made so that the pressure difference on the piston opposite surfaces pushes the piston from the channel opening socket. Piston is equipped with telescopic extension, sliding along channel for piston direction in channel between open position and closed position.

EFFECT: technical result is improvement of compactness of valve, as well as provision of economic solution, which prevents leakage.
