A drip emitter has a flexible membrane for regulating a flow of liquid exiting the emitter. The membrane, in a non-stressed or non-flexed state into a regulating chamber of the emitter, includes a non-planar portion.

An apparatus, especially adapted for regulating flow of in-line drip irrigation device emitters. The disclosed apparatus converts high liquid flow to a low flow rate as low as 0.02 gallons per hour. The liquid is introduced at a controlled high flow rate, such as by the use of a pressurized fluid supply conduit. The liquid then flows into a number of inlet inflow gates before traversing a pressure responding diaphragm. The closing pressure response of the pressure responding diaphragm, provided primarily by a number of elastomeric o-rings, must be overcome by the pressurized fluid entering through the inlet inflow gates before transmitting regulated fluid flow through an outlet means, wherein said ancillary elastomeric o-ring is a rubber annular component assembled with a tubular rigid insert prior to insertion of drip line extrusion. The present invention provides an apparatus and method for regulating flow of pressure-responding diaphragms of extruded in-line irrigation device emitters'.

A greenwall cladding system for the growth of organisms such as plants and fungi on the side of structures, such as internal and external walls of buildings, is provided. Methods for the production of organisms on a greenwall cladding system, such as plants and fungi are also provided herein.

The present invention relates to an emitter that can properly exhibit a flow rate adjustment function even when produced by molding a resin material having low hardness. The emitter has an emitter body and a base part stored in the emitter body. The emitter body comprises a water intake part, a reduced-pressure flow path groove, a storage part, and a diaphragm part. The base part has a base, a communication hole, and a deformation prevention part that is disposed protruding from the reverse surface to the surface of the base which the diaphragm part deformed by the pressure of a drip irrigation liquid contacts, and when the diaphragm part contacts the base by the pressure of the drip irrigation liquid, contacts the tube to prevent the base from being deformed by the pressure of the drip irrigation liquid.

Weed barrier systems of one or more long lasting weed barrier sheets of flexible polymer or plant material impervious to light and water with precut holes to grow a single to more than 100 plants of different sizes and/or open ended planters which inhibit or prevent weed growth and facilitate root zone targeted water and nutrient delivery are provided.

Disclosed herein are embodiments of a device that is useful for drip irrigation. The device comprises a drip line connection unit, a valve and a measurement unit that counts water drops. And the device may further comprise a control unit. The device attached to a drip irrigation line and produces water drops of a known size, counts the number of drops to determine the volume of water being applied, and shuts off the water flow once a desired amount of water has been provided.

An emitter provided with: a water intake part that communicates with the interior of a tube when the emitter is joined to the tube; a pressure-reducing flow channel part for forming a pressure-reducing flow channel; a flow rate adjustment part for adjusting the flow rate of the irrigation liquid in accordance with the pressure of the irrigation liquid inside the tube; and a discharge part that faces a discharge opening. The flow rate adjustment part has: a base; an accommodation part that accommodates the base; a communication hole that opens to the base and communicates with the discharge part; and a diaphragm part that is flexible and is disposed so as to be separated from the base, the diaphragm part approaching the base when the pressure of the irrigation liquid inside the tube is received.

A drip emitter sized for insertion into a liquid supply tube and positioned adjacent to a dripping aperture in the tube comprises an emitter body having a convex side configured to internally and adjacently fit the tube and an opposite flat side comprising a regulator, wherein the convex side comprises an outlet chamber configured to be fluidically connected to the dripping aperture; a membrane covering at least the regulator; a cover provided with a liquid intake having a filter, wherein the cover is configured to envelop the emitter body except of most of said convex side; and a locking mechanism connecting the flat side and an inner surface of the cover that is adjacent to the flat side so as to join the cover to the emitter body, wherein the membrane is retained therebetween.

A ball valve for controlling the flow of water to a drip hose is provided. The ball valve includes a manifold including a manifold inlet configured to attach to a riser hose, and one or more valves integrated with the manifold. One or more outlet fittings are attached to each valve adjacent to each valve outlet.

This emitter (120) comprises: a first flow rate adjustment unit which adjusts the flow rate of an irrigation liquid according to the deformation of a first diaphragm (160); and a second flow rate adjustment unit which adjusts the amount of irrigation liquid ejected (discharged) from the emitter (120) according to the deformation of a second diaphragm (170). The first diaphragm (160) has a projection spaced apart by a space from a hole which is a flow path for the irrigation liquid. The projection has an inverted truncated cone shape and is formed so that the space widens as the projection goes into the hole.
