IN LINE BUTTON DRIP EMITTER

摘要

A drip irrigation emitter may be provided with a coupler for bonding to an inner surface of a conduit. The emitter may include for example a button flow restrictor. The coupler may optionally provide an outlet zone on the conduit surface that is large enough for automated perforation. Bonding the emitter to the surface of the conduit may have a minimal effect on the dimensions and/or properties of the conduit. A button drip irrigation emitter may optionally include a two part labyrinth. The labyrinth may for example be confined between a cylindrical surface and a cover and/or wind between intermeshing baffles on the cover and/or the surface.

1. A drip emitter for bonding to an inner surface of a conduit over less than the circumference thereof of comprising:
a body including,
a cylindrical element having a main axis;a closed perimeter fluid outlet zone bounded by a rim having an arched profile which lies on a substantially cylindrical virtual surface, wherein an axis of said substantially cylindrical virtual surface is substantially perpendicular to said main axis of said cylindrical element; a cover including,
a cylindrical inner surface; anda fluid inlet; a labyrinth flow path confined between said cylindrical element and said cylindrical inner surface and wherein said labyrinth flow path is disposed between said fluid inlet and said closed perimeter fluid outlet zone; and an orientation element indicating an orientation of said arched profile for aligning said arched profile with the inner surface of the conduit.
