Nozzle With Improved Close-In Water Distribution
摘要:
A nozzle is provided having a primary outlet for distribution of water relatively distant from the nozzle and a secondary outlet for distribution of water relatively close to the nozzle. The nozzle includes a threaded portion for coupling the nozzle to a source of pressurized water. A flow channel to the secondary outlet is formed through the threads to provide an appropriate pressure drop to improve water distribution to terrain relatively close to the nozzle. The flow channel may cut across the threads or may extend in the same direction as the threads. The flow channel may be tortuous or non-tortuous based on the number of directional changes in the flow channel, thereby allowing the tailoring of close-in water distribution characteristics.
