Variable-flow nozzle for cooling tower

摘要

A water spray nozzle (3) for cooling tower is provided. Wherein, the nozzle (3) or the upper connection section of the nozzle (3) has an upward extension section in a water distribution groove (1). Several layers of water inlet holes or slots (4) are opened around the extension section at different heights, or several tapered water inlets (5) with downward taper tips are distributed around the extension section. The nozzle (3) far from a water distribution port can still get the uniformly distributed water even when the water quantity of the cooling tower is low, the efficiency of the cooling tower thereby will not be reduced.

1. A water spraying nozzle for a cooling tower, comprising a nozzle or an upper connection section of a nozzle, wherein, the nozzle or upper connection section of the nozzle has an upward solid wall extension section for extending into a water distribution channel, the extension section having a plurality of water inflow holes in the form of inverted conical water inflow holes, evenly distributed on an external periphery of the extension section, in which the holes are oriented with their respective apexes at the lowest point, on a periphery of the extension section, whereupon to achieve self-adapting water distribution effect against variations of water inflow.
