| 摘要 |
The present invention discloses a sprinkler head for use in drip irrigation systems. Irrigation fluid entering an inlet is directed through a path comprising a plurality of pressure dropping chambers before emerging through irrigation tubings connected to outlet openings from where the irrigation fluid emerges at a low pressure drip irrigation flow rate. In the preferred embodiment disclosed, the pressure dropping chambers comprise a plurality of series interconnected vortices disposed within stacked plates. The entire assembly can be disassembled for cleaning purposes. The assembly further incorporates an integral pressure regulator for performing an initial step decrease in the pressure of the irrigation fluid before the fluid enters the multiple chambered pressure dropping path. The integral pressure regulator is adjustable and calibrated in gallon per hour flow rates.
