GAS PRESSURE REGULATOR Russian patent published in 2023 - IPC G05D16/10 

FIELD: gas industry.

SUBSTANCE: invention relates to the field of natural gas pressure regulation. The gas pressure regulator comprises an external housing with a cover, in which an electric generator is located, connected to the electric generator through a control device, a heating cable located in the wall of the external housing, a reducing mechanism, including a housing provided with a cover, a seat fixed with the help of plates and a piston valve equipped with a spring. The piston valve forms a feedback cavity with the reducing mechanism body and a control cavity communicated with the amplifier. The booster consists of a body, inside of which a spring-loaded double valve and a piston are coaxially installed, equipped with an adjusting screw and a spring with a force of up to 90% of the outlet pressure behind the gas pressure regulator. In this case, the double valve forms two cavities with the amplifier body, one of which is in communication with the control cavity, and the other with the output of the reducing mechanism and the piston.

EFFECT: increasing the stability of gas pressure regulation, as well as increasing the reliability of the device.
