摘要:
This emitter (120) has double ridges provided around a hole (173) which forms a portion of a flow path between a reduced-pressure flow path and a discharge part. A first ridge (174), which is the outermost ridge, is provided with four first grooves (177) which intersect said ridge. A second ridge (175) is provided with one second groove (178) which intersects said ridge. As the external liquid pressure increases, a film (140) sequentially adheres to the first ridge (174) and the second ridge (175). The flow rate of an irrigation liquid is adjusted to an amount capable of passing through the groove or grooves in the ridge to which the film (140) is adhered.
摘要:
A drip irrigation system for irrigating one or more zones and/or areas. The irrigation system comprises a waterline and one or more drip watering devices. The one or more drip watering devices are able to fit around and attach to a wire, a frame, a post a hook, a vertical pole and/or a horizontal pole quickly and easily without the use of screws or other tools. In some embodiments, the one or more watering devices comprise a u-shaped recess that is configured to accept one or more hanging pots and/or baskets. Coupling the one or more hanging pots and/or baskets with the one or more watering devices opens the valve to drip irrigate the hanging pots and/or baskets through one or more drip lines.

A piece insertion method for a pipe, for example an irrigation pipe, including: ejecting at least one piece, for example a dripper, from an ejection unit, advancing the at least one dripper inside the irrigation pipe by a dripper advancing unit, lifting the dripper towards the inner surface of the irrigation pipe by using a lifting device such that the dripper is parallel or substantially parallel to this inner surface of the irrigation pipe on impact with this inner surface. The method according to the invention allows also coordination between the lifting device, the ejection unit and the dripper advancing unit such that the dripper spacing can be maintained in tight tolerances.

An irrigation emitter and drip line, and methods relating to same, are provided for reducing the flow and pressure of fluid via an emitter or plurality of emitters defined by two concentric tubes. In one form, the first tube defines an emitter inlet and connected pressure-reducing flow channel and the second tube is extruded over the first tube to enclose the emitter inlet and flow channel and defines an outlet connected to an end of the flow channel opposite the inlet to create an emitter for converting fluid flowing at a high flow rate in the lumen and at the first end of the inlet to a fluid with a low flow rate at the outlet of the emitter. In another form, a drip line is provided having a plurality of such emitters. Various other forms and methods relating to the emitter and drip line are also disclosed.

An irrigation drip emitter, and methods relating to same, are provided for delivering irrigation water from a supply tube to an emitter outlet at a reduced and relatively constant flow rate. The emitter having at least one movable member for compensating for fluctuations in supply line fluid pressure. In one form the movable member includes a tapered baffle section movable between a first position wherein fluid is allowed to flow over the tapered baffle section and a second position wherein fluid is prevented from flowing over at least a portion of the tapered baffle section and the tapered baffle section effectively lengthening the extent of a pressure reduction passage. In another form, first and second movable members are provided for compensating for such pressure fluctuations. In another form, a plurality of inputs are provided which are movable between first and second positions to compensate for such pressure fluctuations.

A travelling agricultural irrigation installation is provided having multiple generally horizontal irrigation sprinklers each being a length of pipe closed at each end and having multiple outlet orifice sets along the length thereof. Each orifice is in the form of a hole through the pipe wall having an orifice diameter selected to provide, in use, a jet of water that breaks up into droplets. Each orifice set comprises multiple orifices having axes extending in different angular directions relative to the pipe axis to provide a generally rectangular spray pattern. The length of each sprinkler pipe or the number of orifice sets is dependent on the speed at which the sprinkler is to move over the ground. Typically the installation is a centre pivot installation; the sprinkler pipes are all connected to a common radial main supply pipe; and the water delivery increases with increased distance from the centre pivot.

A drip irrigation tube is provided with metering elements comprising respectively inlet regions, through which the water in the tube arrives in the metering elements, metering regions, formed by a labyrinth channel, which is delimited by two lateral walls, a cover and the walling of the drip irrigation tube and in which a pressure reduction of the water flowing through takes place, and outlet regions, through which the water emerges out of the drip irrigation tube via outlet openings made in the tube walling. The respective outlet region borders at least on one lateral wall, of the labyrinth channel; at least one region of this lateral wall is covered by an elastic membrane forming a portion of the cover, so that the lateral wall is able to be lifted off of the tube wall by means of the elastic membrane and forms a passage through which the water from the labyrinth channel arrives directly in the outlet region. The water flowing through the metering element can thereby be metered depending upon the water pressure in the drip irrigation tube.
摘要:
A bracket for hanging drip irrigation system water supply tubing and micro-tubing having a wire hanger portion for attachment to a drip irrigation system suspension wire; a micro-irrigation tube hanging portion adapted for releasably capturing and securing micro-irrigation tubing in fluid communication; and a water supply tube portion disposed between said wire hanger portion and said micro-irrigation tube hanging portion, said water supply tube portion for releasably and slidingly clamping onto a drip irrigation water supply tube.
摘要:
A drip irrigation system valve for placement directly onto soil, including a valve chamber defining an interior space and having an open bottom in fluid communication with the soil onto which it is placed; a water inlet in fluid communication with said interior space and having a valve seat disposed on an interior end; a base stake connected to said valve chamber for insertion into soil; a platform for supporting an expandable member; an expandable member disposed on said platform within said interior space; a valve membrane disposed within said interior space above said expandable member and having an upper side and a lower side and which defines a water reservoir within said interior space above said upper side and which prevents water entering into said valve chamber and from directly contacting said expandable membrane; and a valve seal disposed on said upper side of said valve membrane immediately above said expandable member for sealing engagement with said valve seat when said expandable member is wetted and in an expanded state.
摘要:
A control system for a low-volume irrigation system includes a plurality of valve controllers for opening and closing valves; an irrigation system controller for controlling the valve controllers in accordance with an irrigation plan; and a graphical user interface for allowing a user to interact with the irrigation controller and to create the irrigation plan. The graphical user interface displays an irrigation zone list, an irrigation set list, and an irrigation plan field. The user interface has drag and drop functionality that permits an irrigation zone listing from the irrigation zone list to be dragged and dropped into any of the irrigation set listings in the irrigation set list and that permits an irrigation zone listing or an irrigation set listing to be dragged and dropped into the irrigation plan to create irrigation steps within the irrigation plan.
