Our company produces various cooling tower sprinkler devices made of ABS material, featuring three-jet nozzles with an external threaded connection for pipe connection. Below the external threaded connection, there are successively coaxial and evenly spaced large splash plate, small splash plate, and conical deflector head, with decreasing external diameters. At least two rods are vertically arranged around the circumference and fixed to the external threaded connection. On the large and small splash plates, there are also large and small drain holes coaxial with the conical nozzle mouth, with decreasing internal diameters compared to the lower internal diameter of the conical nozzle mouth. The large and small splash plates are hemispherical with the curved surface facing up, and the conical deflector head is conical with the tip facing upwards.
