Belonging to the technical field of
combustible gas mixing, the invention particularly relates to a high-precision
combustible gas mixer. The high-precision
combustible gas mixer comprises a support seat, a
mixing tank is fixedly mounted at the top of the support seat, a first
threaded rod is rotatably mounted in the
mixing tank, a speed reducing motor is fixedly mounted on one side of the mixingtank, one end of the first
threaded rod extends out of the
mixing tank and is fixedly connected to an output shaft of the speed reducing motor, a
piston is slidably and airtightly installed in the mixing tank, the
piston is in threaded connection with the first
threaded rod, a sliding rod is fixedly installed in the mixing tank, and the sliding rod runs through the
piston and is slidably and airtightly connected to the piston. The high-precision combustible gas mixer provided by the invention is easy to operate, high in practicability and adjustable in volume, can guarantee the mixing efficiency and precision in mixing gas of any volume, at the same time can change the pressure and flow of different
raw material gases during entering, can balance the
pressure difference when different rawmaterial gases enter, and improves the mixing precision.
