The utility model relates to an oil gas tank pressure gauge fast calibration gauge stand. The oil gas tank pressure gauge fast calibration gauge stand includes a T-shaped pipeline; the tail end of a vertical pipeline of the T-shaped pipeline is provided with a small ball valve; the middle of the vertical pipeline of the T-shaped pipeline is provided with a small ball valve; a plurality of small ball valves are connected in parallel with a horizontal pipeline of the T-shaped pipeline; the small ball valves are connected with threaded joints; each threaded joint is provided with a fast pressure joint which is matched with the threaded joint; and two ends of the horizontal pipeline of the T-shaped pipeline are provided with plugs of three-way valves. With the oil gas tank pressure gauge fast calibration gauge stand adopted, when being tested, pressure gauges are not needed to be disassembled, and only a power source is required to be switched off, and no influences will be exerted on screw threads, sealing components, binding posts and connection pipelines of the gauges; the pressure gauges can be directly tested on site, and a maintenance period can be shortened; when the pressure gauges are tested, connection is simple, reliable and intuitive, and each gauge can be tested alone; the pipelines are convenient to disassemble, and are easy to clean, and oil discharge and gas discharge are not required; the gauges are convenient to replace, and the gauges can be disassembled with hands only required; and damage to the gauges caused by collision in a transportation process can be eliminated.
