Further improve is that the lower fixed seat, fixed limit gas seat, movable limit gas seat, upper fixed seat pass through
Screw is fixedly connected.
Further improve is, is additionally provided with the dial with gear on the pedestal of the movable limit gas seat.
Further improve is that the lower fixed seat lower end surface is additionally provided with the adjusting knob with gear dial.
Further improve is that the band gear type dial adjusting knob passes through lower fixed seat and fixed limit gas seat
It is contacted with the gear type dial matching on the pedestal of movable limit gas seat, for adjusting the cone of movable limit gas seat upper end closed
The open and-shut mode of fan-shaped gate in shape protrusion.
Further improve is that the dial with gear on the pedestal of the movable limit gas seat is adjusted by scale
0 °~120 ° of the range of angle.
The utility model can be accurately adjusted on movable limit gas seat by the dial with gear compared with prior art
The open and-shut mode of fan-shaped gate in closed tapered protrusion is held, to control air inflow, eliminates and artificially by virtue of experience adjusts air inlet
The drawbacks of amount, at the same lower fixed seat lower end surface be equipped with the dial adjusting knob with gear, convenient for operation so that air with
The linear blend range of combustion gas is big, good mixing property, greatly improves the venturi fuel gas mixer of combustion apparatus service performance, together
When, the movable limit gas seat is the tapered protrusion hollow structure and fixed limit gas seat Matching installation of upper end closed, it is not easy to
Generate " whister-type noise " of air-flow mixing.
