PROBLEM TO BE SOLVED: To provide a rise temperature control device of a high-pressure gas supply facility pipeline capable of effectively suppressing rise of gas temperature due to adiabatic compression and impulse wave compression heat in a valve such as a pressure adjustment valve and an opening/closing valve in a high-pressure gas supply facility.SOLUTION: A rise temperature control device 1 of a high-pressure gas supply facility pipeline includes a first valve 5 provided in a high-pressure side pipeline 3 through which high-pressure gas passes and partitioning a high-pressure side and a low-pressure side, and a second valve 9 provided in a low-pressure side pipeline 7 on the downstream side of the first valve 5. A multi-stage orifice 11 constituted from two stages to four stages is provided between the first valve 5 and the second valve 9 and at a position in the vicinity of the first valve 5 with respect to the intermediate position of the first valve 5 and the second valve 9. |
