The
flame gun
nozzle comprises a connecting end and a
nozzle end which are connected, the connecting end is provided with an air
inlet channel, an air inlet cavity, an air outlet hole, an air outlet cavity, an air storage cavity, a first connecting channel and a second connecting channel are formed in the
nozzle end, one end of the air inlet cavity is communicated with the air
inlet channel, and the other end of the air inlet cavity is communicated with one end of the air outlet hole; the other end of the air outlet hole communicates with the air outlet cavity, the air storage cavity communicates with the air inlet cavity through a first connecting channel, and the air storage cavity communicates with the air outlet cavity through a second connecting channel. When the
flame gun nozzle carries out
flame spraying work, combustible
mixed gas enters the nozzle end from the connecting end and then is sprayed out for
combustion, and meanwhile the combustible
mixed gas enters the gas storage cavity through the first connecting channel and then is output to the gas outlet cavity in the radial direction through the second connecting channel. The pressure of the radially output gas can slow down the speed of the
mixed gas sprayed out of the gas outlet, so that the flame is prevented from being too far away from the gun nozzle to be extinguished, and the effect of stabilizing the flame is achieved.
