Embodiment
As shown in FIG. 1, FIG. 1 is a kind of tripper of the utility model circle round air entraining valve, including discharge nozzle, air inlet pipe, into
Expects pipe, buckle, discharge nozzle 1, feed pipe 3 pass through 4 detachable connections of buckle.As shown in Fig. 2, air inlet pipe 2 is vertically installed in out
On the pipe face of expects pipe 1, and it is connected with the inside of discharge nozzle 1.
As shown in figure 3, being equipped with unidirectional baffle 32 inside the pipeline of feed pipe 3, one end of unidirectional baffle 32 passes through rotating bar
It is rotatably dispose in feed pipe.When charging, pressure when unidirectional baffle 32 is due to feeding, with the rotating bar that is laterally arranged for rotation
Axis is opened along feedstock direction, when the air pressure applied in air inlet pipe is excessive, generates reflux, unidirectional baffle 32 is closed, prevents
Flow back the damage generated to equipment.
Buckle 4 is uniformly arranged on the outside of air entraining valve, and buckle 4 includes the fixing groove 41 being fixed on discharge nozzle 1, is fixed on
Rotating bar 42 on feed pipe 3, when fixed, rotating bar 42 is fastened on fixing groove 41；When disassembly, rotating bar 42 is rotated, and will be discharged
