A gas regulator includes: an inlet section fluidically connected to a gas inlet in the regulator, an outlet section fluidically connected to at least one gas outlet from the regulator; a shutter assembly which is movable so as to define at least one opening position in which the gas passes from the inlet section to the outlet section through a restriction, thus generating a pressure drop of the gas, and therefore of a temperature, such as to cause the precipitation/solidification of some substances, in particular the fractions of sulfur and/or its derivative compounds, present in the gas; and an outlet filter with mechanical action which is positioned downstream of the restriction, inside said regulator, to thus retain any solid particles deriving from the precipitation/solidification. The at least one outlet of the gas from the regulator is fluidically connected with a portion downstream of the outlet filter.

Gas regulator

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:

Apparatus for pressure regulating

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.
