The fire water cannon has two spraying functions of direct current and blooming. When spraying water column, it can extinguish long-distance solid fire; when spraying blooming water mist, it can be used for cooling down the fire site and fire rescue. Because of its complete functions, stable performance, novel structure and convenient operation, the fire water cannon is widely used in heavy fire trucks and fire ships, and can also be used as fixed fire extinguishing equipment for industrial and mining enterprises, warehouses, oil fields and storage tanks.

1. The structural composition of the fixed fire monitor: the fixed fire monitor mainly includes the connection base, the bracket water inlet pipe, the rotary body, and the nozzle (including:

Outlet pipe, water inlet pipe, double handles), gun handle, etc., the nozzle of the water monitor is straight-spray type, (see Figure 1 for details);

2. The working principle of the fixed fire monitor:

b. When spraying: After the water flow passes through the fixed fire monitor body, the angle between the water flow and the flow stabilizer changes by rotating the nozzle, and is sprayed from the nozzle to form a mist-like water flow.
