COMBINED GAS PRESSURE REGULATOR Russian patent published in 2016 - IPC G05D16/06 

FIELD: gas industry.

SUBSTANCE: gas pressure regulator relates to device for automatic maintenance of working medium pressure at specified level and is designed to provide natural gas supply to industrial and household consumers. Proposed combined gas pressure regulator comprises housing connected to valve through seat, and actuator connected to housing and comprising membrane chamber including head and actuator cover, between which there is movable system of membrane type (membrane), control valve, at that, it includes rod-piston made with possibility of back-and-forth movement in holder located under membrane actuator and enables transmission of force developed by membrane actuator to regulator control valve. At that, rod-piston contact surface area is equal to area of holes in actuator control seat minus cross-sectional area of rod passing through seat.

EFFECT: higher reliability and accuracy of valve reducing; providing development of drive membrane sufficient forces for tight closure of valve, which directly depends on output pressure value; possibility of using device in compliance with proposed invention as gas pressure control, and as and safety valve.
