Summary: | The utility model relates to a portable tank vehicle normal pressure tank breather valve calibration device. The portable tank vehicle normal pressure tank breather valve calibration device comprises a gas circuit control unit, a signal conditioning module, a signal acquisition module, a signal processing module and a signal display module. According to the utility model, the pressure of the air outlet valve and the air inlet valve of the breather valve can be verified on a tank truck regular inspection site; the air outlet pressure value and the air inlet pressure value are displayed on a nixie tube or a liquid crystal display screen in real time; respectively displaying the maximum pressure value and the minimum pressure value when the verification is finished; and the change of the pressure in the gas circuit where the breather valve is located in the verification process can be recorded in the whole process, and recorded data can be uploaded to a computer through a serial port or sent to a tablet personal |
