Distribution tube assembly for irrigation

Abstract

A distribution tube assembly for an irrigation system having a main supply line for conveying fluid therein includes a first end, a second end and an internal surface defining at least two fluid passageways, at least one of the fluid passageways being in fluid communication with the main supply line. The other fluid passageway may be in fluid communication with an alternate supply line. Adaptors and regulators may be attached to the distribution tube assembly. The distribution tube assembly permits irrigation to be performed by multiple fluid streams, allows for the incorporation of chemicals within the distribution tube assembly, and provides for selectable flow control.

       26 . A distribution tube assembly for an irrigation system of the type having a main supply line for conveying fluid, the distribution tube assembly comprising a distribution tube frame having a first conduit which defines a first passageway and a second conduit which defines a second passageway, the first and second passageways being fluidly separate from each other throughout the frame, the conduits being joined by a web, at least one of the first and second passageways being in fluid communication with the main supply line. 
   
   
       27 . The distribution tube assembly of  claim 26  further comprising an adaptor. 
   
   
       28 . The distribution tube assembly of  claim 27  wherein the adaptor comprises a branch fitting in fluid communication with at least one of the first and second passageways. 
   
   
       29 . A distribution tube assembly for an irrigation system of the type having a main supply line for conveying fluid, the distribution tube assembly comprising a distribution tube frame having a first conduit which defines an irrigation fluid passageway and a second conduit which defines a pilot pressure fluid passageway, the irrigation fluid passageway being in fluid communication with the main supply line, the pilot pressure fluid passageway being in fluid communication with a pilot pressure fluid.
