Netafim is a company in the field of irrigation for agriculture and landscaping. The company focuses on crops in the area of drip irrigation, greenhouse turnkey projects, and biofuel energy crops. Founded in 1965, Netafim introduced a new concept of low-volume irrigation, launching the drip irrigation revolution. Wikipedia.


Patent
Netafim | Date: 2013-02-04

For indoor mushroom cultivation, a method of irrigating the mushrooms includes drip irrigation pipes in the bed. The drip irrigation pipes can be disposed in a casing layer that overlies a substrate layer, and irrigation can be according to measurements taken in the environment outside of the bed.

A pulsating irrigation device is provided that transforms a fluid flow entering the device to an intermittent pulsating fluid flow that is ejected from the device. The device has a chamber and at least one compressible member in pressure contact with the chamber. The compressible member compresses to assist the formation of the pulses ejected from the device and the fluid within the chamber is substantially sealed from contact with the interior of the compressible member.

An aeration system for a bed of ore that is laid upon a basal layer has a gas source located upstream for supplying gas and aeration pipes that distribute the gas downstream to the bed. Each aeration pipe has spaced-apart gas emitters that distribute gas to the bed and the aeration pipes extend through the bed towards the basal layer.

A pulsating device has a chamber for receiving liquid entering the device and gas that occupies an initial volume in the chamber. The liquid entering the chamber compresses the gas and decreases the volume occupied by the gas, thereby increasing the pressure in the chamber. A valve is provided to open above a first threshold pressure to begin a pulse of liquid. The valve closes below a second threshold pressure to end the pulse. The pulsating device has an outlet gate that permits liquid in the chamber to exit the chamber when the pressure in the chamber is greater than the pressure outside the chamber.

A drip irrigation emitter receives liquid flowing in an irrigation pipe at an inlet pressure and emits the liquid out of the emitter at an outlet pressure lower than the inlet pressure. The emitter has a flow path through which the liquid flows in the emitter, wherein below a threshold pressure of liquid in the pipe the emitter is adapted to emit a regulated flow of liquid out of the emitter, and above the threshold pressure of liquid in the pipe the emitter is adapted to emit a non-regulated flow of liquid out of the emitter.
