Description of the drawings
Fig. 1 is the utility model structure principle chart.
Specific embodiment
Referring to accompanying drawing, a kind of welded insulated gas cylinder Daily boil-off-rate measuring instrument, it includes：The housing 1 of display 6 is installed,
And the gas mass flow controller 2 inside housing 1, controller 8, power supply 13；
Housing 1 is enclosed construction, and which has IN, an OUT, tri- interfaces of the 2nd OUT；In IN interface, an OUT interface
Between pipeline on be provided with the first valve 11 and gas mass flow controller 2；Between IN interface, the 2nd OUT interface
Pipeline on be provided with the second valve 3；The first temperature sensor 7, pressure is provided with pipeline between the first valve 11, IN interface

Operation principle of the present utility model is：Before test, by welded insulated gas cylinder gas vent and IN interface be connected to one
Rise, the second valve 3 is opened, the first valve 11 is closed, makes the gas in welded insulated gas cylinder discharge from the 2nd OUT interface, until
Pressure sensor 9 shows that the gas in pipeline is normal pressure；The second valve 3 is closed, the first valve 11 is opened, makes welded insulated gas cylinder
Interior gas is discharged from an OUT interface, adjusts aperture and the gaseous mass of the first valve 11 during this using controller 8
Valve opening inside flow controller 2, when the pressure that pressure sensor 9 is gathered is basicly stable, and welded insulated gas cylinder flow
During numerical stability, the reading for starting reading gas mass flow controller 2 obtains the Daily boil-off-rate value of welded insulated gas cylinder.
