Our company produces various cooling tower spray devices with ABS material triple-jet nozzles, featuring an external threaded connection to the pipe manifold. Below the external threaded connection, there are successively coaxial and spaced large splash trays, small splash trays, and conical baffle heads with decreasing diameters. Additionally, at least two rods are vertically arranged around the circumference and fixed to the external threaded connection. On the large and small splash trays, there are also large and small drain holes coaxial with the conical nozzle mouth, with the inner diameters decreasing in sequence. The large and small splash trays are hemispherical with the curved surface facing up, and the conical baffle head is conical with the tip pointing upwards.
