Abstract
Description
L'objet de l'invention concerne un distributeur d'eau sans pression pour arrosage goutte à goutte. The object of the invention relates to a pressureless water distributor for drip irrigation.
II est destiné à assurer une distribution régulière de l'eau et principalement à éviter le colmatage des orifices de distribution, de répartition et d'écoulement. It is intended to ensure a regular distribution of water and mainly to avoid clogging of the distribution, distribution and flow orifices.
11 est connu d'utiliser des manchons perforés pour la distribution d'eau à l'interieur des tuyaux d'arrosage avec des profils séparateurs et des répartiteurs d'eau à la hauteur des orifices d'écoulement disposés à des intervalles déterminés sur les conduites distributrices . Mais ces orifices d'obturaient rapidement et l'écoulement des eaux était irrégulier, rendant inopérantes les installations. It is known to use perforated sleeves for the distribution of water inside the garden hoses with separator profiles and water distributors at the height of the flow orifices arranged at predetermined intervals on the pipes. vending machines. But these orifices closed quickly and the flow of water was irregular, rendering the installations inoperative.
Le dispositif suivant l'invention supprime ces inconvénients et permet un usage régulier et constant sans intervention pour une durée comparable à celle des vergers ou plantation où il est installé, il assure en même temps qu'un auto-nettoyaae aussi bien des orifices de distribution que des chicanes séparant la nappe de fluide répartie et collectée à la hauteur des orifices d'écoulement à entailles transversales prononcées, évitant leur obturation tout en augrnentant ses qualités résistantes de structuration de sorte qu'ilpeut subir des efforts de traction, torsion ou autres sans déformation ni risque de rupture. The device according to the invention eliminates these drawbacks and allows regular and constant use without intervention for a period comparable to that of the orchards or plantation where it is installed, it ensures at the same time that a self-cleaning as well as distribution orifices that baffles separating the sheet of fluid distributed and collected at the height of the flow orifices with pronounced transverse notches, preventing them from being blocked while increasing its resistant structural properties so that it can undergo tensile, twisting or other forces without deformation or risk of rupture.
II est constitué par la combinaison, d'abord, d'un manchon pourvu d'orifices de répartition du fluide implantés longitudinalement sur toute la longueur du manchon, ensuite des positionnements de chicanes générant par l'écoulement du fluide, une turbulence intense auto-nettoyant et enfin, des orifices distribution ou l'écoulement avec des rainures ou entailles évasées à large orifice. supprimant les riques d'obstruction. It consists of the combination, first of all, of a sleeve provided with fluid distribution orifices implanted longitudinally over the entire length of the sleeve, then positioning of baffles generating, by the flow of the fluid, intense self-turbulence. cleaning and finally, distribution or flow orifices with flared grooves or notches with large orifice. removing the risk of obstruction.
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 montre vu en élévation le dispositif dans son ensemble.In the appended drawings given by way of nonlimiting example of one of the embodiments of the subject of the invention:
Figure 1 shows in elevation the device as a whole.
Les figures 2 et 3 représentent, à une échelle différente, des détails d'exécution des éléments répartiteurs. Figures 2 and 3 show, on a different scale, details of execution of the distributing elements.
La figure 5 est une vue en coupe de la mise en place du manchon à l'intèrieur d'un conduit d'arrosage. Figure 5 is a sectional view of the establishment of the sleeve inside a sprinkler pipe.
Le distributeur d'eau sans pression (Fig. 1, 2, 3) est constitué par un manchon en substance rigide 1 avec orifice à ouverture intégrale 2, 3. The pressureless water dispenser (Fig. 1, 2, 3) consists of a rigid substance sleeve 1 with an integral opening 2, 3.
Il comporte à chacune de ses extrémités un collecteur 4,5 circulaire. Sur toute sa longueur sont posés des orifices de très petit diamètre 6,7 et autres, perpendiculaires à la paroi cylindrique du manchon. It has at each of its ends a circular manifold 4,5. Over its entire length are placed holes of very small diameter 6.7 and others, perpendicular to the cylindrical wall of the sleeve.
Ces orifices de distribution d'eau s'écoulent dans le conduit 19 retiennent les salissures 16 d'une dimension supèrieure à leur diamètre. Ces salissures sont auto-nettoyées par le passage de l'eau sans pression qui s'écoule. These water distribution orifices flow into the conduit 19 retain the soiling 16 of a dimension greater than their diameter. These soils are self-cleaning by the passage of water without pressure flowing.
Les gouttelettes se déversent dans les chicanes périphériques 8, 9 et qui créent (Fig. 3) des turbulences 10 autonettoyantes qui dissolvent les salissures de très petite dimension qui ont pu passer à travers les orifices 6, 7 avant de s'écouler le long des rainures longitudinales 11, 12, 13. The droplets flow into the peripheral baffles 8, 9 and which create (Fig. 3) self-cleaning turbulences 10 which dissolve very small dirt which may have passed through the orifices 6, 7 before flowing along the longitudinal grooves 11, 12, 13.
La veine d'eau ainsi canalisée se déverse dans les collecteurs d'extrémités 4, 5. Le conduit porteur 6 est perçé par des entailles évasées 14, 15, flèches A, B d'oû s'écoule la distribution goutte à goutte. The vein of water thus channeled pours into the end collectors 4, 5. The carrying duct 6 is pierced by flared notches 14, 15, arrows A, B from which the distribution flows drop by drop.
L'évasement des orifices et leur largeur évitent toute agglomération des salissures aussi bien chimiques qu'électrostatiques ou autres. The flaring of the orifices and their width prevent any agglomeration of dirt, whether chemical, electrostatic or other.
Les orifices capillaires ou de très petite dimension 6, 7 sont soit cylindriques, soit à tronc conique avec orifice réduit à leur petite base, si une salissure de petite dimension 16 obstrue cette base, le courant sans pression 17 flèche D la chasse position 16', et elle est ensuite entrainée, flèche C dans la canalisation 6, flèche E. The capillary orifices of very small dimension 6, 7 are either cylindrical, or with conical trunk with orifice reduced to their small base, if a small dimension of dirt 16 obstructs this base, the current without pressure 17 arrow D flush position 16 ' , and it is then driven, arrow C in line 6, arrow E.
Si la salissure est de plus petite dimension, elles est entrainée à travers les chicanes 8, 9 (Fig. 3) où le tourbillonnement 10 l'auto-nettoie et l'entraine vers les collecteurs
L, 5, d'oû elles sont expulsées par les orifices évasés 1t, 15 qui ne s'obstruent ainsi jamais.If the dirt is of smaller dimension, they are entrained through the baffles 8, 9 (Fig. 3) where the swirl 10 self-cleans and entrains it towards the collectors
L, 5, from which they are expelled through the flared orifices 1t, 15 which thus never become blocked.
Si le manchon 20 (Fig 4) subit une déformation, il résiste et les orifices 6, 7 longitudinaux qui suivent une génératrice linéaire, n'amorcent pas de rupture comme ce serait le cas avec les orifices radiaux généralement utilisés jusqu'à ce jour. If the sleeve 20 (FIG. 4) undergoes a deformation, it resists and the longitudinal orifices 6, 7 which follow a linear generator, do not initiate rupture as would be the case with the radial orifices generally used to date.
Ce distributeur d'eau sans pression est monté ou placé dans un tuyau d'irrigation dit goutte-à-goutte par tous moyens appropriés. This pressureless water distributor is mounted or placed in a so-called drip irrigation pipe by any suitable means.
Il peut être introduit avec mandrin ou tout appa-reillage approprié et sa structuration par sa perforation ponctuelle linéaire assure un débit constant de très grand volume vu la quantité de perforation mais auto-résistant par sa structuration longitudinale et transversale sans aucun point faible ni possibilité d'amorce de rupture en cas de torsion ou autre 20 (Fig 4), de sorte qu'il présente un maximum d'effets utiles par rapport aux distributeurs utilisés jusqu'à ce jour. It can be introduced with a mandrel or any suitable fitting and its structuring by its punctual linear perforation ensures a constant flow of very large volume given the quantity of perforation but self-resisting by its longitudinal and transverse structuring without any weak point or possibility of initiation of rupture in the event of torsion or the like 20 (FIG. 4), so that it has a maximum of useful effects compared to the distributors used to date.
Il est possible de relier par un fil conducteur et à la terre 25 le manchon 1 et le conduit 19, évitant les effets électromagnétiques d'agglomération des salissures. It is possible to connect the sleeve 1 and the duct 19 to a ground wire 25 and to the ground 25, avoiding the electromagnetic effects of agglomeration of dirt.
Toutefois les formes, dimensions et dispositions des différents éléments, comme d'ailleurs les matières utilisées pour leur fabrication pourront varier dans la limite des équivalents 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, as indeed the materials used for their manufacture may vary within the limit of equivalents without changing the general conception of the invention which has just been described.
