Abstract
Description
L'objet de l'invention concerne un dispositif autoréqulateur agricole pour la distribution goutte à goutte destiné à l'irrigation des terres. The object of the invention relates to an agricultural self-leveling device for drip distribution intended for land irrigation.
Il est destiné à assurer la répartition de quantité
d'eauprédéterminée volumétriquement et d'une façon continue sur
les espaces à arroser.It is intended to ensure the distribution of quantity
predetermined volume of water volumetrically and continuously over
spaces to water.
Il est connu d'utiliser des goutteurs autorégulants. It is known to use self-regulating drippers.
Les uns sont à autorégulation proportionnelle qui s'effectue à partir d'un seuil élevé de 1,5 bar jusqu'à 4 bars avec un régime laminaire. Les autres sont à régulation alternative régulant depuis 0,5 bars, mais entre 3 et 4 bars la dispersion des résultats est importante car le régime est turbulent.Some are proportional self-regulation which is carried out from a high threshold of 1.5 bar up to 4 bar with a laminar regime. The others are with alternative regulation regulating from 0.5 bars, but between 3 and 4 bars the dispersion of the results is important because the regime is turbulent.
L'objet de l'invention supprime ces inconvénients et permet d'équilibrer la plage de régulation tout en l'élevant de à à 6 bars en utilisant un régime hydraulique à la fois semi laminaire et semi turbulent. The object of the invention eliminates these drawbacks and makes it possible to balance the regulation range while increasing it from to to 6 bars by using a hydraulic regime which is both semi-laminar and semi-turbulent.
Il se caractérise par la combinaison d'un labyrinthe en chicane circulaire avec échancrure radiale de circuit direct imprimée sur sa face de contact et d'une membrane mobile et souple, élastique et déformable sous l'effet de la pression d'eau qui la fait plaquer contre le labyrinthe. It is characterized by the combination of a labyrinth in circular baffle with radial notch of direct circuit printed on its contact face and a mobile and flexible membrane, elastic and deformable under the effect of the water pressure which makes it press against the labyrinth.
Sur les dessins annexés donnés à titre d'exemple non limitatif d'une des formes de réalisation de l'objet de l'invention, la figure 1 représente, vu en élévation et en coupe, le dispositif dans son ensemble. La figure 2 montre le détail constructif du labyrinthe caractérisant l'invention. In the accompanying drawings given by way of nonlimiting example of one of the embodiments of the object of the invention, FIG. 1 represents, seen in elevation and in section, the device as a whole. Figure 2 shows the constructive detail of the labyrinth characterizing the invention.
Le distributeur goutte à goutte est constitué figure 1 par une base 1 comportant à sa partie axiale un élément d'ajutage profilé et tubulaire 2 qu'on introduit dans une canalisation d'alimentation 3 afin d'ancrer une jonction étanche
Ce conduit 4 débouche dans une capacité 5 étanchéisée par un couvercle ou carter 6 dont le parement infèrieur 7 comporte gravé un labyrinthe circulaire 8 figure 2.The drip dispenser is constituted in FIG. 1 by a base 1 comprising at its axial part a profiled and tubular nozzle element 2 which is introduced into a supply pipe 3 in order to anchor a tight junction
This conduit 4 opens into a capacity 5 sealed by a cover or casing 6 whose lower facing 7 has etched a circular labyrinth 8 in FIG. 2.
Dans l'axe de ce labyrinthe est disposé le conduit d'écoulement 9 dont la base 10 est de diamètre réduit. In the axis of this labyrinth is disposed the flow conduit 9, the base 10 of which is of reduced diameter.
Dans la capacité 5 est placée une membrane souple élastique et déformable 11. In capacity 5 is placed a flexible elastic and deformable membrane 11.
Le labyrinthe 8 est réalisé par un flasque comportant une série de gorges circulaires concentriques 12, 13, 14 et autres. The labyrinth 8 is produced by a flange comprising a series of concentric circular grooves 12, 13, 14 and the like.
Urne lare échancrure radiale 15 relie la périphérie à l'orifice d'écoulement 10
Le parement supèrieur ].6' de la membrane 11 entre progressivement en contact avec le labyrinthe 8.Large radial indentation urn 15 connects the periphery to the flow orifice 10
The upper facing] .6 'of the membrane 11 progressively comes into contact with the labyrinth 8.
C'est la combinaison des effets du labyrinthe en chicane 8 du circuit direct 15 et de la membrane élastique déformable sous l'effet de la pression d'eau subie par la face 16 que se caractérise 1' invention. It is the combination of the effects of the baffle labyrinth 8 of the direct circuit 15 and of the elastic membrane deformable under the effect of the water pressure undergone by the face 16 that the invention is characterized.
Le circuit direct 15 10 est ouvert à faible pression et s'obture progressivement au fur et à mesure que la pression augmente. The direct circuit 15 10 is open at low pressure and gradually closes as the pressure increases.
Sous l'effet de la pression d'eau,la membrane obture ce circuit 15 et seui le labyrinthe assure l'écoulement de la périphérie 17 vers le centre 10. Under the effect of the water pressure, the membrane closes this circuit 15 and only the labyrinth ensures the flow from the periphery 17 to the center 10.
C'est la conjugaison de ces deux circuits qui assure avec une précision maximale la régulation proportionnelle du goutte à goutte de 0,4 " 6 bars. It is the combination of these two circuits which ensures with maximum precision the proportional regulation of the drip of 0.4 "6 bars.
Ce distributeur permet l'utilisation de rampes d'adductions plus larges pour un diamètre nominal elevé ce qui abaisse le prix de revient du coût des installations à l'hectare. This distributor allows the use of wider supply ramps for a high nominal diameter which lowers the cost price of the cost of installations per hectare.
Il corrige automatiquement des baisses de pressions importantes qui se produisent dans les conduits alimentant plusieurs distributeurs. It automatically corrects significant pressure drops that occur in the conduits supplying several distributors.
I1 assure un débit uniforme quel que soit le nombre et l'écartement des positionnements sur un même conduit. I1 ensures a uniform flow regardless of the number and spacing of the positions on the same duct.
Toutefois les formes, dimensions et dispositions des différents éléments pourront varier dans la limite des équivalents comme d'ailleurs les matières utilisées pour leur fabrication, sans changer pour cela la conception générale de l'invention qui vient d'être décrite. However, the shapes, dimensions and arrangements of the various elements may vary within the limit of the equivalents, as moreover the materials used for their manufacture, without thereby changing the general conception of the invention which has just been described.
