description The utility model discloses an atmospheric pressure tank breather valve calibration device for a portable tank truck. The device comprises a base, a breather valve joint and a gas storage bottle arranged on the base, a connecting pipe with a stop valve is arranged on the gas storage bottle; the end part of the connecting pipe is connected with a connector; a connecting groove communicated with theconnecting pipe is formed in one side of the connector; the outer part of the connector is in threaded connection with a threaded sleeve; positioning plates arranged in a matrix mode are fixed to theinner walls of the connecting grooves. A plurality of movable holes communicated with the connecting groove are formed in the outer wall of the connector; therefore, the breather valve connector canbe conveniently connected into the connecting groove in a butt joint mode, the positioning sleeve can drive the pressing rod to extrude the pressing block when the threaded sleeve is rotated, the pressing block can abut against
