Seen from the above description, the proportional quantity of the injection pressure of nozzle and natural gas and air is determined by required firing temperature
It is fixed, the weight of counterweight can by ejection medium in nozzle pressure and require spray distance to be calculated, when the spray in nozzle
One timing of pressure of medium is penetrated, the angle overturn under the impact of ejection medium of the counterweight in nozzle increases with the quality of counterweight
Reduce greatly；When the constant area for the injection channel that the inner wall of the inner wall of counterweight and jet port is formed, the jet pressure of nozzle
Power is constant, and spray distance is constant.
Further, further includes:
When nozzle injection, when detecting that actual spray distance is less than the required spray distance, increase nozzle cage
The length of the injection channel of main body.
Seen from the above description, the extended length of injection channel, gas burn more evenly in injection channel, and air pressure is more steady
It is fixed, it can be improved range of jet and fire effect.
Further, step S2 is specifically included:
The counterweight is mounted at jet port by a pin shaft, and the first limit shaft and the second limit are arranged at jet port
Position axis, first limit shaft are located above the second limit shaft；
When the injection pressure value of nozzle is greater than preset upper limit value, the counterweight is resisted against on the first limit shaft；Work as spray
When the injection pressure value of mouth is less than preset lower limit value, the counterweight is resisted against on the second limit shaft.
Seen from the above description, the first limit shaft and the second limit shaft play the role of limit and protection, guarantee nozzle work
The stability of work.
