Abstract
Description
La présente invention a pour objet un dispositif pour l'irrigation goutte a goutte, encore appelé ggoutteur", qui est utilisé dans le domaine de
l'irrigation, pour assurer une émission et une distribution goutte à goutte d'un liquide, généralement de l'eau, selon un débit très faible.The present invention relates to a device for drip irrigation, also called drip "which is used in the field of
irrigation, to ensure a drop-by-drop emission and distribution of a liquid, generally water, at a very low flow rate.
Le brevet principal décrit un tel dispositif qui comprend un circuit de perte de charge placé entre un orifice d'alimentation en liquide sous pression et un orifice d'émission du liquide goutte à goutte, et caractérisé en ce qu'il comporte : une embase formant une pièce male rigide munie d'un embout pour son
insertion dans un tube d'alimentation, dans laquelle est réalisé de moulage un premier circuit de perte de charge ; un capuchon formant une pièce femelle rigide qui vient s'encliqueter sur l'embase et qui comporte un embout pour son
introduction par piquage dans un tube d'alimentation, et dans laquelle est réalisé de moulage un second circuit de perte de charge communiquant avec le premier, et une membrane interposée entre les deux circuits de perte de charge, et qui est réalisée sous la forme d'une pièce cylindrique plate constituée d'un matériau souple et élastique, afin d'assurer l'étanchéite entre les deux circuits de perte de charge, l'auto-régulation > par déformation et appui sur les zones annulaires de l'embase et du capuchon, respectivement, et le rôle d'un clapet anti-retour
La présente invention concerne en conséquence un dispositif d'irrigation du type objet du brevet principal, caractérisé en ce que le capuchon compulse un siège de forme cylindrique, en saillie par rapport au circuit de perte de charge, prévu dans ce capuchon, de manière que la membrane interposée entre les deux circuits de perte de charge soit én appui permanent, par déformation, pour assurer l'étanchéité.The main patent describes such a device which comprises a pressure drop circuit placed between a port for supplying pressurized liquid and a port for emitting the liquid drop by drop, and characterized in that it comprises: a base forming a rigid male part provided with a tip for its
insertion into a supply tube, in which a first pressure drop circuit is produced by molding; a cap forming a rigid female part which snaps onto the base and which has a tip for its
introduction by stitching into a supply tube, and in which a second pressure drop circuit communicating with the first is produced by molding, and a membrane interposed between the two pressure drop circuits, and which is produced in the form of a '' a flat cylindrical piece made of a flexible and elastic material, in order to ensure sealing between the two pressure drop circuits, self-regulation> by deformation and support on the annular zones of the base and the cap, respectively, and the role of a non-return valve
The present invention therefore relates to an irrigation device of the type object of the main patent, characterized in that the cap compulses a seat of cylindrical shape, projecting from the pressure drop circuit, provided in this cap, so that the membrane interposed between the two pressure drop circuits is in permanent support, by deformation, to ensure sealing.
Selon une autre caractéristique de cette addition, l'embase comporte un siège de forme cylindrique muni de fentes radiales, de manière å permettre un écoulement de l'eau sans perte de charge. According to another characteristic of this addition, the base comprises a cylindrical seat provided with radial slots, so as to allow water to flow without loss of load.
D'autres caractéristiques et avantages de cette addition ressortiront de la description faite ci-après en référence à la figure unique du dessin annexé qui représente le dispositif selon l'addition, selon une vue en élévation, en demi-coupe axiale longitudinale. Other characteristics and advantages of this addition will emerge from the description given below with reference to the single figure of the appended drawing which represents the device according to the addition, in an elevation view, in longitudinal axial half-section.
Sur la figure, on voit que, comme dans le dispositif décrit dans le brevet principal, le goutteur objet des cette addition comprend essentiellement
- une embase 10, constituée par une pièce male rigide comportant un circuit de perte de charge 18
- un capuchon 12, constitué par une pièce femelle rigide comportant un second circuit de perte de charge 16 et qui vient s'encliqueter sur l'embase 10 et
- une membrane 14, en un matériau souple de préférence, qui est interposée entre l'embase 10 et le capuchon 12.In the figure, we see that, as in the device described in the main patent, the dripper object of this addition essentially comprises
- a base 10, consisting of a rigid male part comprising a pressure drop circuit 18
a cap 12, constituted by a rigid female part comprising a second pressure drop circuit 16 and which snaps onto the base 10 and
a membrane 14, preferably made of a flexible material, which is interposed between the base 10 and the cap 12.
Selon l'additiQn, la membrane souple 14 qui peut ou non assurer une fonction d'auto-régulation du débit d'eau distribué par le dispositif goutte, joue également le rôle de clapet anti-retour. According to the additiQn, the flexible membrane 14 which may or may not provide a self-regulating function of the water flow distributed by the drop device, also plays the role of non-return valve.
A cet effet, le capuchon 12, constitué par une pièce cylindrique, comporte un siège 20 de forme cylindrique, ménagé autour de l'orifice axial 26 du capuchon, et qui se trouve en saillie par rapport au circuit de perte de charge 16, de manière à réaliser un contact permanent de la membrane 14, par déformation de celle-ci, en vue d'assurer l'étanchéité. To this end, the cap 12, constituted by a cylindrical piece, comprises a seat 20 of cylindrical shape, formed around the axial orifice 26 of the cap, and which is projecting relative to the pressure drop circuit 16, so as to make permanent contact with the membrane 14, by deformation thereof, in order to ensure sealing.
De préférence, la valeur de la partie en saillie du siège 20 par rapport au niveau des parois délimitant les chicanes du circuit de perte de charge 16 est de l'ordre de 0,3 mm. Preferably, the value of the projecting part of the seat 20 relative to the level of the walls delimiting the baffles of the pressure drop circuit 16 is of the order of 0.3 mm.
Par ailleurs, l'embase 10 comporte un siège central 22 de forme cylindrique et muni de fentes 24 de manière à permettre un écoulement de l'eau, sans perte de charge. Furthermore, the base 10 comprises a central seat 22 of cylindrical shape and provided with slots 24 so as to allow a flow of water, without pressure drop.
Parmi les avantages apportés par ce dispositif, on peut citer notamment
a) La possibilité de doser précisément le débit d'eau de chaque goutteur sur de grandes longueurs de tube appelé "lignes porte-goutteurs" ; en effet, actuellement ces lignes se vident à chaque arrêt de l'installation, ce qui provoque des dosages irréguliers, ces phénomènes se produisent également a la remise sous pression de l'installation car les premiers goutteurs émettent un débit alors que les plus éloignés ne coulent que beaucoup plus tard.Among the advantages provided by this device, there may be mentioned in particular
a) The possibility of precisely dosing the water flow rate of each dripper over long lengths of tube called "dripper carrier lines"; Indeed, currently these lines are emptied at each stop of the installation, which causes irregular dosages, these phenomena also occur at the re-pressure of the installation because the first drippers emit a flow whereas the most distant do not flow that much later.
b)- Le fait d'éviter sur sol à forte pente, à l'arrêt de l'installation, de dépressuriser la conduite le temps qu'elle se vide et de provoquer une succion des goutteurs au point haut de la ligne donc un risque important de voir les goutteurs en contact avec le sol aspirer des particules qui provoqueront des obturations, à court ou long terme. b) - The fact of avoiding on steep ground, at the stop of the installation, of depressurizing the pipe while it is emptying and of causing a suction of the drippers at the high point of the line therefore a risk important to see the drippers in contact with the ground sucking up particles which will cause blockages, in the short or long term.
Ainsi, le goutteur objet de cette addition permet notamment
- de maintenir ces lignes porte-goutteurs en faible pression ~ 0,200 bar et de ne pas les vider å chaque arrêt de l'installation
- å la remise en pression d'obtenir un démarrage instantané de tous les goutteurs > le débit de chaque goutteur est donc plus précis, même avec un temps d'irrigation très court (pulsations).Thus, the dripper object of this addition allows in particular
- to keep these dripper lines at low pressure ~ 0.200 bar and not to empty them at each stop of the installation
- when the pressure is restored, instantaneous start-up of all drippers is obtained> the flow rate of each dripper is therefore more precise, even with a very short irrigation time (pulsations).
Il demeure bien entendu que cette addition n'est pas limitée à l'exemple décrit et représenté mais qu'elle en englobe toutes les variantes. It remains to be understood that this addition is not limited to the example described and shown but that it includes all the variants.
