Bar, the adjusting rod are uniformly provided with several limit holes along its length, at the top of the fixed plate and are located above the adjusting rod
It is provided with threaded hole, the threaded hole internal whorl is connected with fixing bolt, and the adjusting rod runs through the fixed plate, and the tune
Pole is fixed with rotating handles far from one end of the steady combustion bluff body, and the adjusting rod is fixed close to one end of the steady combustion bluff body
There is connecting bracket, the connecting bracket is fixed with current stabilization ring far from one end of the adjusting rod, and the current stabilization ring is a kind of taper
Ring, and the current stabilization ring both side ends are provided with card slot, the fixed plate side is fixed with oil gun.
Preferably, the current stabilization ring is identical as the steady combustion bluff body material.
Preferably, the fixing bolt matches with the limit hole.
Preferably, the adjusting rod and the fixed plate joint are respectively and fixedly provided with stop collar.
Preferably, the current stabilization ring matches with the nozzle body internal diameter, and the nozzle body inside outlet
Place two sides are respectively and fixedly provided with fixture block, and the fixture block and the card slot size match.
The utility model proposes a kind of nozzle of direct current combustor, beneficial effect is: by burner nozzle ontology
Top increases a fixed plate and adjusting rod, is imitated by the fixed current stabilization ring in adjusting rod top in the reflux for improving breeze airflow
It answers, and installs oil gun additional in fixed plate, the usage amount for helping fuel oil can be saved.
