GAS PRESSURE REGULATOR AMPLIFIER Russian patent published in 2020 - IPC G05D16/20 

FIELD: machine building.

SUBSTANCE: in the gas pressure regulator amplifier in the measuring piston, controlling through the rod and monovalve with two valves – working and discharge valves, to generate command pressure on actuator of gas pressure regulator by comparing force from feedback pressure behind gas pressure regulator from one side of piston and spring setting on other side, rod is arranged with possibility of its movement relative to measuring piston. Said rod is equipped with additional feedback piston arranged in bushing and forming with it a cavity communicated with working valve. Pressure variation in the network is taken as a feedback by a measuring piston acting on the working valve to generate command pressure to the actuator of the gas pressure regulator for recovery of the specified pressure level in the network. Simultaneously with opposite measuring piston displacement of additional feedback piston causes opposite sign change, magnitude of command pressure on actuator of pressure regulator, thereby eliminating possibility of overshooting, i.e. improving control quality. For remote control of amplifier in order to change level of gas pressure adjustment behind pressure regulator or its correction amplifier is equipped with rotary electromechanism.

EFFECT: disclosed is gas pressure regulator amplifier.
