The utility model relates to a gas flow orifice plate heat insulation device, and belongs to the technical field of gas pipeline heat insulation equipment, which is used for insulating heat of a gas flow orifice pate of a coke furnace. The device adopts the technical scheme that the device consists of two annular heating pipes and a plurality of branch pipes, wherein the two annular heating pipes surround the gas flow orifice pate, and are fixedly connected with the gas flow orifice pate via a connecting device, the annular circular heating pipes are mutually parallel with each other, and are communicated by the vertical branch pipes, and steam inlet pipelines and steam outlet pipelines of the two annular heating pipes are respectively with a steam inlet control valve and a steam exhaust control valve. The device has the advantages that the gas flow orifice plate is heated and subjected to heat insulation by the annular heating pipes and the branch pipes utilizing the low-pressure steam, the temperature is un
