Abstract: Apparatus for regulating gas pressure suitable for use in systems and/or networks for transport and/or distribution of gas, the apparatus configured to be connected upstream with an inlet duct for the gas and downstream with an outlet duct, and includes: a main regulator including: an inlet area fluidically connectable with the inlet, an outlet area fluidically connectable with the outlet, a shutter which acts between the inlet area and the outlet area, means configured to push the shutter towards a closed position, a motorization chamber in which a movable element is housed, a pilot regulator including: an inlet which is fluidically connected with a first sub-chamber, to thus allow the passage of gas from the first sub-chamber towards an inlet of the pilot regulator, an outlet which is fluidically connected to said second sub-chamber, and at least one pilot valve.

Abstract: A control system for a natural gas distribution network, includes: a processing unit suited to communicate, through corresponding signals, with one or more control devices operatively connected to the distribution network; a rechargeable battery which supplies power to the processing unit; a power supply device suited to recharge the rechargeable battery. The power supply device includes: a thermoelectric generator connected to the rechargeable battery; a first heat exchanger and a second heat exchanger respectively in contact with two opposite sides of the thermoelectric generator; a vortex tube which receives part of the natural gas from the distribution network and divides it into a colder portion and into a warmer portion; a first duct suited to convey the colder portion into the first heat exchanger; a second duct suited to convey the warmer portion into the second heat exchanger.
