Abstract

A valve comprises: a housing defining a chamber; a fluid outlet defined by a fluid outlet wall; and a first fluid outlet orifice and a second fluid outlet orifice comprising a rigid seat. The valve comprises a movable gate, that is flexible and/or compressible and impermeable. The moveable gate is more flexible than the rigid seat, has a planar surface, and is configured to slidably move in a first axis. The movable gate is configured to be positioned so that it is located between a fluid inlet orifice and the second fluid outlet orifice when the valve is in a closed position, wherein fluid pressure within the chamber causes the movable gate to seal the second fluid outlet orifice via the rigid seat, and not the fluid inlet orifice. The valve may employ gate shapes that generate and/or exploit Bernoulli effect forces when fluid passes though the valve.

Abstract

An irrigation valve comprises a housing including a chamber, a fluid inlet comprising a fluid inlet passage configured to fluidly communicate with a first conduit, wherein the fluid inlet is configured to communicate fluid from the first conduit to the chamber, a fluid outlet comprising a fluid outlet passage configured to fluidly communicate with a second conduit, wherein the fluid outlet is configured to communicate fluid from the chamber to the second conduit, a rigid substrate and a stretchable, compressible and/or flexible membrane on a surface of the rigid substrate, wherein the rigid substrate is configured to be positioned so that the membrane is located between the fluid inlet and the fluid outlet when the valve is in a closed position, and wherein a fluid pressure within the chamber causes the membrane to seal a first orifice of the fluid outlet passage when the valve is in the closed position.
