Abstract

Improved installation of drip irrigation, which being of special application in the different bypass and sub-bypass pipes that constitute the installation itself, is essentially characterized in that at each convenient point of the pipe, preferably made of soft polyethylene, is carried out radially a small perforation or orifice communicated with the interior of the pipe and that determines the means of exit of the water, in such a way that on said perforation or orifice a ring or clamp is mounted covering said perforation, breaking, on its inner face, the water that will form in the form of a trickle through the orifice, turning it into a regular and permanent drip; with the particularity that the perforation itself is done in cold and with needles of 0.8 and 1.2 mm thick, producing a subsequent contraction of the hole of tenth and a half to two tenths of mm. Approximately, in such a way that such perforation can be done by hand or by machine in the agricultural farm where the installation is mounted. 2. Improved installation of drip irrigation, according to claim 1, characterized in that the ring or clamp is equipped with a recess made in the central and inner part thereof, said recess being faced with the perforation of the pipe, to thereby act of decompression chamber and a slippage of the liquid through its internal walls, dropping it by drops. 3. Improved installation of drip irrigation, according to claims 1 and 2, characterized in that the inside of the ring has been made longitudinally conical that allows a graduation of the water outlet by the throttling that occurs when the ring or clamp is clamped against the pipe itself. 4. Improved installation of drip irrigation, according to previous claims, characterized in that the central recess with which the ring is provided, part a spiral of fine pitch and shallow depth, so that when circulating water at the bottom of the spiral, it produces a pressure loss and the consequent pressure drop so that the water comes out in the form of a drip. 5. Improved installation of drip irrigation, according to previous claims, characterized in that the ring or clamp is capable of being equipped, according to the lateral edges that limit its bases, a flange or protruding rib. 6. Improved installation of drip irrigation. (Machine-translation by Google Translate, not legally binding)
