Adjustable flow bubbler for drip irrigation systems

摘要

A drip irrigation water distribution device having a housing with a top, bottom and side wall forming a chamber therein. The bottom of the housing has a rotatable coupling attached thereto and configured for attachment to a water conduit member, such as a riser, to allow water under pressure to enter the bubbler. A plurality of valves are disposed in valve openings in the housing. Each valve is in corresponding relationship with a valve receiving member that has an opening in communication with the chamber and a discharge passage. An outlet member connects to a distribution line. The opening is configured to receive a reduced section of the valve to selectively allow water to flow to the discharge passage. The opening is securely closed by lowering the reduced section until it tightly abuts against the opening. An integral screen is included to filter debris in the water supply.
