Abstract:
An irrigation pipe that extends along an axis and has a pipe wall with a base portion (55) and a plurality of bulge members (1, 2) that extends away from the base portion.
Abstract:
An irrigation pipe is formed from a sheet rolled into a tube about a longitudinal axis. The sheet has a fabric layer and an outer layer formed on the fabric layer, wherein the pipe comprises axially extending load bearing members extending in contact with the outer layer.
Abstract:
A valve apparatus (10) comprising an inlet (40) and an outlet (42), and having a first state where liquid is stopped from flowing from the inlet (40) towards the outlet (42), a second state where liquid is released to flow from the inlet (40) towards and out of the outlet (42), and a terminal state where after flowing out of the outlet (42) the liquid is stopped form flowing out of the outlet (42). An incoming command triggers the apparatus (10) from the first state towards the second state and at or after the terminal state the apparatus (10) transmits an outgoing command out of the apparatus (10).
Abstract:
A rotating sprinkler (14) configured to be used with a pulsating device (12) that forms pulses that have a beginning and an end. The sprinkler has a rotating portion (16) that can rotate about an axis (X) while emitting the liquid pulses to the outside environment, and the rotating portion (16) is adapted to stop to rotate before the end of each liquid pulse.
Abstract:
An irrigation valve has a liquid passage, a sealing diaphragm and a control port that can receive control signals. The sealing diaphragm is held in the valve in a non clamped manner and is adapted to seal the passage. Upon receipt of a control signal the sealing diaphragm bends and opens a path for liquid around the sealing diaphragm that can exit the valve.
Abstract:
A drip irrigation emitter 10 receives liquid flowing in an irrigation pipe at an inlet pressure and emits the liquid out of the emitter 10 at an outlet pressure lower than the inlet pressure. The emitter comprising a flow path 20 through which the liquid flows in the emitter 10, wherein below a threshold pressure of liquid in the pipe the emitter 10 is adapted to emit a regulated flow of liquid out of the emitter 10, and above the threshold pressure of liquid in the pipe the emitter 10 is adapted to emit a non - regulated flow of liquid out of the emitter.
Abstract:
An irrigation pipe connector (16) has a core (18) that is adapted to connect to an irrigation element (40) and a wing (20) that is attachable to a wall of a pipe (10). The wing (20) is provided with resiliency to allow the connector (16) to deform in response to changing fluid pressures in the pipe (10). In addition, the wing (20) may be provided with a thin segment in order to reduce potential damage during welding of the wing to the wall of the pipe (10).
Abstract:
A water provisioning device for use with an irrigation channel for providing water into an irrigation pipe. The water provisioning device comprises a primary reservoir adapted to maintain water up to a predetermined level and comprising a primary outlet adapted for being brought in fluid communication with the irrigation pipe. The system further comprises at least one primary inlet tube in the form of a siphon tube with a proximal end manually insertable into said channel for drawing water therefrom and a distal end adapted for the initiation of suction within the tube and for the disposition in said reservoir at least after the suction has been initiated, to supply said water thereto.
Abstract:
A tensiometer for use in determining matric potential of a soil comprising: a water inlet; a hydraulic coupler comprising a porous material for providing hydraulic coupling between water that enters the inlet and the soil; and a septum that seals water that enters the inlet against ingress of air via the porous material.
