AUTOMATIC GAS EQUIPMENT UNIT WITH ELECTROHYDRAULIC DRIVES FOR GAS SUPPLY INTO BOILER MODULAR BURNER Russian patent published in 2025 - IPC F23N1/00 F16K11/00 

FIELD: combustion apparatus.

SUBSTANCE: invention relates to automatic gas equipment unit. Automatic gas equipment unit for gas supply to the modular boiler burner containing the main burner and located in its central part a pilot burner intended for constant operation during the main burner operation, containing in-series located first shut-off valve and second shut-off valve, intended for installation on gas line to main burner, and gas line to pilot burner. Shutoff members of the first shutoff valve and the second shutoff valve are located in the same housing, on the cover of which electrohydraulic drives of the first valve and the second valve are located, housing is made with inlet and outlet nozzles, a first cavity connected to the inlet nozzle, a second cavity connected to the outlet nozzle and an intermediate chamber separated from the first and second cavities by the first and second shut-off members of the valves, at that, in the first shut-off valve in the gas direction, namely in its electro-hydraulic drive, a pneumatic regulator is built-in, which pulse tube is connected to the intermediate chamber, which allows the first shut-off valve to perform the function of a constant gas pressure regulator in the intermediate chamber, which is connected to the pilot burner gas line with the pilot burner normally closed valve and to the safety gas line with the normally open safety valve.

EFFECT: expanded operating performances of automatic gas equipment units.
