The systems for producing hot water for heating and domestic hot water generally include:
  • a domestic cold water inlet pipe connected to a cold water circuit;
  • a fluid fuel burner transferring heat to a main heat exchanger connected on the one hand, to the cold water circuit and on the other hand to a primary hot water circuit;
  • a domestic hot water outlet pipe connected to a domestic heat exchanger interposed between the cold water circuit and the primary hot water circuit;
  • a hydraulic distributor valve making it possible to select either the sanitary operating mode or the heating operating mode of the production system, mode in which the primary hot water circuit is connected to a heating circuit comprising at least one radiator itself even connected to the cold water circuit, the valve comprising an axis linked to a train of valves opening and closing orifices located in the primary hot water circuit;
  • a hydraulic motor comprising an enclosure divided, by a membrane, into an upstream chamber and a downstream chamber, the upstream chamber being subjected to the pressure prevailing in the cold water inlet pipe, upstream of restriction means positioned in the cold water circuit causing, during the passage of cold water, a pressure difference in the inlet pipe, and the downstream chamber being in fluid communication with the restriction means to be subjected to the pressure prevailing in the pipe cold water inlet, downstream of said means, said membrane being displaceable under the effect of the pressure difference existing between said two upstream and downstream chambers and, the displacement of the membrane being transmitted to the axis of the valve;
  • a fluid fuel supply which delivers a quantity of fuel controlled by the passage of cold water in the cold water inlet pipe and controlled by means of the displacements of the membrane.

Dans ce type de conception usuelle des systèmes de production de chauffage, les chambres des vannes distributrices hydrauliques sont reliées aux moyens de restriction de la conduite d'entrée d'eau froide, qui sont chargés d'élaborer la différence de pression, et en amont de ces moyens, à l'aide de canalisations ou conduites disposant de leurs moyens de connexion et de leurs moyens d'étanchéité.In this type of usual design of heating production, valve chambers hydraulic distributors are connected to the means of restriction of the cold water inlet pipe, which are responsible for developing the pressure difference, and upstream of these means, using pipes or conduits having of their means of connection and their means sealing.

La vanne distributrice hydraulique constitue l'un des éléments majeurs du système de production de chauffage. Elle en constitue donc un noeud de connexion entre les différents circuits et éléments, noeud à partir duquel les différents circuits sont mis en relation en fonction de l'état de fonctionnement du système de production de chauffage.The hydraulic distributor valve is one major elements of the heating production system. It therefore constitutes a connection node between the different circuits and elements, node from which the different circuits are linked according to the operating state of the production system of heater.

Il en résulte que les liaisons entre les autres éléments du système de production de chauffage mettent également en oeuvre des moyens de connexion et d'étanchéité. En particulier, la liaison entre les circuits sanitaire et chauffage, l'échangeur et le circulateur utilise des conduites, notamment de cuivre ou analogue, et des joints pour relier l'ensemble de ces pièces.It follows that the connections between the others elements of the heating production system put also using connection and sealing means. In particular, the connection between the sanitary circuits and heating, the exchanger and the circulator uses pipes, especially of copper or the like, and seals to connect all of these pieces.

L'inconvénient majeur de ce type de montage entre la vanne et les autres éléments du système de production de chauffage réside principalement dans le fait qu'il est intrinsèquement générateur de fuites (usure des joints, influence des vibrations qui risquent de générer un desserrage des organes de fixation, coefficient de dilatation thermique différent entre les divers éléments ...). De plus, lors des opérations de maintenance préventive ou curative sur le système de production de chauffage, la complexité des moyens de connexion et leur technologie entre les éléments nuisent aux opérations de montage et/ou de démontage, l'accès à un des éléments pouvant être conditionné par l'emplacement d'un autre par exemple.The major drawback of this type of mounting between the valve and the other elements of the production system of heating mainly lies in the fact that it is intrinsically leak generator (wear of seals, influence of vibrations which may generate a loosening of fasteners, coefficient of different thermal expansion between the various elements ...). In addition, during maintenance operations preventive or curative on the production system of heating, the complexity of the connection means and their technology between the elements hamper the operations of assembly and / or disassembly, access to one of the elements may be conditioned by the location of another by example.

La présente invention vise donc à pallier les inconvénients en proposant une vanne distributrice hydraulique qui simplifie les connexions entre les divers éléments constituant le système de production de chauffage en vue d'optimiser sa maintenance, pour réduction des coûts.The present invention therefore aims to overcome the disadvantages by proposing a distributor valve hydraulic which simplifies the connections between the various elements making up the heating production system in order to optimize its maintenance, to reduce costs.

A cet effet, la vanne distributrice hydraulique se caractérise en ce qu'elle comporte sensiblement un premier et second corps dont des premières extrémités sont reliées respectivement au retour du circuit chauffage et à la conduite d'entrée d'eau froide et des secondes extrémités sont reliées respectivement au moteur hydraulique, entraínant le train de clapet entre deux sièges ouvrant et fermant des orifices situés au sein de la vanne et déterminant soit le mode de fonctionnement sanitaire, soit le mode de fonctionnement chauffage, et à un système générateur de différence de pression comportant les moyens de restriction, ledit système comportant une enveloppe pourvue d'une part, d'au moins deux prises de pression connectées respectivement aux chambres amont et aval de l'enceinte du moteur hydraulique et d'autre part, d'un orifice de départ vers l'échangeur sanitaire, l'orifice de retour de l'échangeur sanitaire étant positionné sur un troisième corps transversal par rapport aux premier et second corps et débouchant dans ledit premier corps, ce dernier étant également pourvu d'un orifice pour la sortie du circuit chauffage, les trois corps et l'enveloppe du système générateur et les orifices étant venus de moulage d'une seule pièce.To this end, the hydraulic distributor valve is characterized in that it comprises substantially a first and second body whose first ends are connected respectively when the heating circuit returns and when cold water inlet pipe and second ends are connected respectively to the hydraulic motor, driving the valve train between two opening seats and closing ports located within the valve and determining either the sanitary operating mode, or the heating operating mode, and to a system pressure difference generator comprising the means restriction, said system comprising an envelope provided on the one hand with at least two pressure taps connected respectively to the upstream and downstream chambers of the enclosure of the hydraulic motor and secondly, a outlet opening to the domestic heat exchanger, the return of the sanitary exchanger being positioned on a third body transverse to the first and second body and opening into said first body, this the latter being also provided with an outlet for the outlet of the heating circuit, the three bodies and the envelope of the generator system and the orifices having come from molding in one piece.

Grâce à ces dispositions, l'ensemble des tubulures de liaison entre le système générateur de différence de pression, le moteur hydraulique, les orifices est supprimé.Thanks to these provisions, all of the tubing of connection between the system generating the difference of pressure, hydraulic motor, orifices is removed.

  • a cold water inlet pipe 1 connected to a cold water circuit making it possible to admit water from the supply network into the installation, with a view to its use as domestic hot water which is consumed by the user or as water for central heating. In the latter case, the water intended for central heating is admitted once during filling of the heating production system, and it is only very sporadically added, especially to maintain the operating pressure. This water is directed to a main heat exchanger 3, commonly called “heating body”, connected on the one hand, to the upstream cold water circuit 4 and on the other hand to a primary hot water circuit 5, downstream . This main heat exchanger is positioned in the flow of combustion gases from a burner 2 so as to exchange the sensible heat of the combustion gases towards the fluid circulating in the exchanger 3;
  • the burner 2 is supplied with gas by means of a supply 6 which delivers a quantity of fuel in particular subject to the quantity of cold water passing through the cold water inlet pipe 1, during operation in sanitary mode. Downstream of the main heat exchanger 3, the hydraulic circuit is divided into several branches 7, 8, 9 each of which is used depending on the type of operation of the installation;
  • the first branch 7 constitutes a bypass between the upstream and downstream of the main heat exchanger 3;

On décrira successivement chacune des seconde 8 et troisième 9 branches du circuit hydraulique.We will successively describe each of the second 8 and third 9 branches of the hydraulic circuit.

La seconde branche 8 se décompose de la manière suivante :The second branch 8 breaks down in the way next :

En sortie de l'échangeur de chaleur principal 3, une première bifurcation est réalisée par l'intermédiaire d'une conduite de sortie d'eau chaude 11 vers un échangeur de chaleur sanitaire 12 interposé entre le circuit eau froide 1 et le circuit primaire d'eau chaude 5.At the outlet of the main heat exchanger 3, a first bifurcation is carried out via a hot water outlet pipe 11 to a heat exchanger domestic heat 12 interposed between the cold water circuit 1 and the primary hot water circuit 5.

Cet échangeur de chaleur sanitaire 12 permet de transférer des calories issues du circuit primaire eau chaude 5 qui traverse l'échangeur de chaleur principal 3 vers le circuit d'eau chaude sanitaire 13. Ce circuit 13 comporte la conduite d'entrée eau froide 1 qui traverse des moyens de restriction 16, (le fonctionnement sera explicité plus en détail plus loin dans la présente description), et une vanne distributrice hydraulique 14 permettant de sélectionner, soit le mode de fonctionnement sanitaire, soit le mode de fonctionnement chauffage du système de production.This sanitary heat exchanger 12 allows transfer calories from the primary water circuit hot 5 passing through the main heat exchanger 3 to the domestic hot water circuit 13. This circuit 13 comprises the cold water inlet pipe 1 which passes through restriction means 16, (the operation will be explained more in detail later in this description), and a hydraulic distributor valve 14 making it possible to select either the sanitary operating mode or the heating system operating mode production.

En mode de fonctionnement sanitaire, la vanne hydraulique 14 qui est pilotée par l'intermédiaire d'un moteur hydraulique 15, lui-même commandé par les moyens de restriction 16, permet d'une part de boucler le circuit hydraulique provenant du circuit primaire eau chaude 5 et d'autre part, de mettre en relation via les moyens de restriction 16, la conduite d'entrée sanitaire 1 avec le circuit d'utilisation sanitaire 13, après passage dans l'échangeur sanitaire 12.In sanitary operating mode, the valve hydraulic 14 which is controlled by a hydraulic motor 15, itself controlled by the means of restriction 16, allows on the one hand to complete the circuit hydraulic from the primary hot water circuit 5 and on the other hand, to connect through the means of restriction 16, the sanitary inlet pipe 1 with the sanitary use circuit 13, after passing through the domestic heat exchanger 12.

La troisième branche 9 se décompose de la manière suivante :The third branch 9 breaks down in the way next :

En sortie de l'échangeur de chaleur principal 3, une seconde bifurcation est réalisée par l'intermédiaire d'une seconde conduite de sortie d'eau chaude 11' vers au moins un radiateur 17 lui-même relié à la vanne hydraulique distributrice 14 à l'amont de l'échangeur principal 3 par l'intermédiaire d'une conduite 18. De manière connue, le circuit de chauffage primaire comporte en série un circulateur 10, ou autrement appelé accélérateur ou pompe, ainsi qu'un vase d'expansion 19 chargé d'absorber les variations de pression dues au changement des paramètres physico-chimiques du fluide en circulation.At the outlet of the main heat exchanger 3, a second bifurcation is carried out via a second hot water outlet pipe 11 'to at least one radiator 17 itself connected to the hydraulic valve distributor 14 upstream of the main exchanger 3 by through a pipe 18. In known manner, the primary heating circuit includes in series a circulator 10, or otherwise called accelerator or pump, as well as an expansion tank 19 responsible for absorbing the pressure variations due to changing parameters physico-chemical of the circulating fluid.

On se reportera maintenant à la figure 2 qui représente notamment la vanne hydraulique distributrice 14, le moteur hydraulique 15 ainsi que les moyens de restriction 16.We will now refer to Figure 2 which represents in particular the hydraulic distributor valve 14, the hydraulic motor 15 as well as the restriction means 16.

La vanne hydraulique 14 constitue l'un des éléments essentiels du système de production d'eau chaude de chauffage et d'eau chaude sanitaire.The hydraulic valve 14 constitutes one of the elements essentials of the hot water production system heating and domestic hot water.

Obtenue par une technique de moulage d'une matière plastique, telle que notamment des polymères, choisis notamment parmi les polyoxyphénylènes chargés à 30 % de fibres de verre, pour lui conférer à la fois de la légèreté, de la robustesse, elle se présente sous la forme d'un produit monobloc. Le polymère pourrait être également choisi parmi les polyamides, ou des mélanges de polymères.Obtained by a technique of molding a material plastic, such as in particular polymers, chosen in particular among the polyoxyphenylenes charged with 30% of glass fibers, to give it both lightness, robustness, it comes in the form of a monobloc product. The polymer could also be chosen among polyamides, or mixtures of polymers.

La vanne comporte sensiblement un premier corps 20 et un second corps 21, notamment cylindrique, reliés par une paroi frontale venue de fabrication. Chacun des corps 20 et 21 dispose en leurs extrémités d'orifices, nécessaires à la fois, à la connexion de ladite vanne aux conduites du système de production d'eau chaude sanitaire et d'eau chaude de chauffage et aux autres éléments complémentaires à l'installation. Le second corps 21 est pourvu d'un orifice permettant à l'utilisateur d'effectuer des compléments en eau, cet orifice venu de fabrication avec le reste du corps de la vanne 14 comporte un moyen de connexion rapide à épingle.The valve comprises substantially a first body 20 and a second body 21, in particular cylindrical, connected by a front wall from manufacturing. Each of the bodies 20 and 21 has at their ends orifices, necessary for the times, at the connection of said valve to the pipes of the domestic hot water and hot water production system heating and other elements complementary to installation. The second body 21 is provided with an orifice allowing the user to perform add-ons water, this orifice that came from manufacturing with the rest of the body valve 14 has a quick connection means to pin.

Ainsi, des premières extrémités 22, 23 des premier et second corps sont reliées respectivement au retour du circuit chauffage 18 et à la conduite d'entrée d'eau froide 1 et des secondes extrémités 24, 25 sont reliées respectivement au moteur hydraulique 15, entraínant un train de clapet 26 entre deux sièges 27, 28 ouvrant et fermant des orifices situés au sein de la vanne 14 et déterminant soit le mode de fonctionnement sanitaire, soit le mode de fonctionnement chauffage et à un système générateur de différence de pression 29 comportant les moyens de restriction 16.Thus, of the first ends 22, 23 of the first and second body are respectively connected to the return of the heating circuit 18 and to the water inlet pipe cold 1 and second ends 24, 25 are connected respectively to the hydraulic motor 15, driving a train valve 26 between two seats 27, 28 opening and closing orifices located within valve 14 and determining either the sanitary operating mode, i.e. the heating operation and a generator system pressure difference 29 comprising the means of restriction 16.

Les orifices destinés à être connectés à des conduites de fluide comportent chacun au moins un épaulement 30 venu de fabrication par moulage. Ces épaulements 30 constituent des sièges pour joint notamment torique, ceux-ci coopérant au niveau de portées cylindriques venant d'embout de connexion (non représenté sur les figures). Ces embouts de connexion réalisés par des techniques de décolletage ou autres disposent d'une partie cylindrique sensiblement au diamètre du joint torique, sur laquelle est positionnée une collerette qui délimite une rainure avec une seconde partie cylindrique coaxiale à la précédente et dont le diamètre correspond sensiblement au diamètre interne de l'un des épaulements desdits orifices.The holes intended to be connected to fluid lines each have at least one shoulder 30 came from manufacturing by molding. These shoulders 30 constitute seats for an O-ring in particular, these cooperating at the level of cylindrical bearing surfaces coming from end piece connection (not shown in the figures). These tips connection made by bar turning techniques or others have a cylindrical part substantially at diameter of the O-ring, on which is positioned a collar which delimits a groove with a second part cylindrical coaxial with the previous one and whose diameter roughly corresponds to the internal diameter of one of the shoulders of said orifices.

La rainure réalisée sur l'embout de connexion, lorsque l'embout est emmanché dans l'orifice et que l'étanchéité est obtenue par la présence du joint torique, se trouve en regard d'un canal 31 tangent audit orifice. Ce canal permet le passage d'une épingle métallique sensiblement de forme β. Le profil de cette épingle permet de verrouiller axialement la position de l'embout dans son orifice.The groove made on the connection end piece, when the nozzle is fitted into the hole and sealing is obtained by the presence of the O-ring, is located opposite a channel 31 tangent to said orifice. This channel allows the passage of a metal pin substantially β-shaped. The profile of this pin allows to axially lock the position of the nozzle in its orifice.

La seconde extrémité 25 du second corps 21 coopère avec le système générateur de différence de pression 29. Cet organe 29 qui est représenté en détail à la figure 5 permet de générer une différence de pression consécutive au débit d'eau froide sanitaire.The second end 25 of the second body 21 cooperates with the pressure difference generating system 29. This member 29 which is shown in detail in Figure 5 allows generate a pressure difference following flow domestic cold water.

Il comprend une enveloppe 33 sensiblement cylindrique venue de fabrication avec le second corps 21 et qui s'étend selon une direction sensiblement perpendiculaire par rapport au plan contenant les premier 20 et second 21 corps. Cette enveloppe 33 permet de relier ledit second corps 21 avec l'un des orifices 34 de connexion avec l'échangeur sanitaire 12. L'enveloppe 33 réalise un fourreau pour l'immobilisation des moyens de restriction 16.It includes an envelope 33 substantially cylindrical coming from manufacturing with the second body 21 and which extends in a substantially perpendicular direction relative to the plane containing the first 20 and second 21 body. This envelope 33 makes it possible to connect said second body 21 with one of the orifices 34 for connection with the sanitary exchanger 12. The casing 33 makes a sheath for the immobilization of the means of restriction 16.

L'immobilisation axiale des moyens de restriction 16 au sein du fourreau délimité par l'enveloppe 33 est obtenue par une technique similaire à l'immobilisation des embouts de connexion au sein de leurs orifices respectifs, c'est-à-dire par un système de fixation rapide par épingle 32.Axial immobilization of the means of restriction 16 within the sheath delimited by the envelope 33 is obtained by a technique similar to immobilizing the tips of connection within their respective orifices, i.e. by a quick fixing system by pin 32.

Le système générateur de différence de pression 29 représenté en figure 5 dispose d'au moins un clapet 35 en regard d'un siège de clapet 36, au moins un orifice calibré 58 au voisinage du siège du clapet 36 permettant de créer en amont du clapet 35 une surpression qui actionne le clapet 35 qui permet de limiter la surpression et d'obtenir le débit nécessaire, des prises de pression 38, 39 s'effectuant au niveau de l'enveloppe 33 de part et d'autre du siège du clapet 36, au moins un organe limiteur de débit 40 d'eau positionné en amont dudit clapet 35, au moins un filtre 41' positionné en amont dudit organe limiteur de débit 40.The pressure difference generating system 29 shown in Figure 5 has at least one valve 35 in manhole of a valve seat 36, at least one calibrated orifice 58 in the vicinity of the seat of the valve 36 making it possible to create in upstream of the valve 35 an overpressure which actuates the valve 35 which allows to limit the overpressure and to obtain the flow necessary, pressure taps 38, 39 taking place at level of the envelope 33 on either side of the seat of the valve 36, at least one flow rate limiting member 40 of water positioned upstream of said valve 35, at least one filter 41 ' positioned upstream of said flow limiting member 40.

Le fonctionnement du système générateur de différence de pression est le suivant. Un débit d'eau sanitaire acheminé par la conduite d'eau sanitaire 1 chemine à l'intérieur du second corps 21 de la vanne hydraulique 14 et débouche au niveau d'une zone annulaire située à l'intérieur de l'alésage de l'enveloppe 33 sensiblement en amont du filtre 41'.et d'un orifice calibré 58, positionné au voisinage du siège du clapet 36. Cet orifice permet de créer en amont du clapet 35 une surpression qui actionne le clapet 35 qui permet de limiter la surpression et d'obtenir le débit nécessaire.The operation of the generator system pressure difference is as follows. A water flow sanitary piped by sanitary water pipe 1 chimney inside the second body 21 of the hydraulic valve 14 and leads to an annular zone located at inside the bore of the casing 33 substantially in upstream of the filter 41 ′. and of a calibrated orifice 58, positioned in the vicinity of the seat of the valve 36. This orifice makes it possible to create an overpressure upstream of the valve 35 which actuates the valve 35 which makes it possible to limit the overpressure and to obtain the required flow.

En aval du siège du clapet 36 se situe une zone de moindre pression qui est reprise par un premier piquage 39 sensiblement radial à l'enveloppe 33.Downstream of the valve seat 36 is an area of less pressure which is taken up by a first stitching 39 substantially radial to the envelope 33.

De même, un second piquage 38 jouxtant le précédent et en relation avec la zone annulaire baignant l'amont du clapet 35 est réalisé sur le corps de l'enveloppe 33 et constitue avec le premier piquage, les prises de pression nécessaires au fonctionnement du moteur hydraulique 15.Similarly, a second stitching 38 adjoining the previous one and in relation to the annular zone surrounding the upstream valve 35 is produced on the body of the casing 33 and constitutes with the first tapping, the pressure taps necessary for the operation of the hydraulic motor 15.

Par ailleurs, la vanne hydraulique distributrice 14 comporte un orifice de retour 41 de l'échangeur sanitaire 12 qui est positionné sur un troisième corps transversal 42 par rapport aux premier 20 et second 21 corps. Ce troisième corps 42, notamment de section droite circulaire, est venu de fabrication avec les précédents et débouche dans ledit premier corps 20, ce dernier étant également pourvu d'un orifice 43 pour la sortie du circuit chauffage. Cet orifice 43 forme un embout qui peut être connecté à la conduite correspondante du système de production d'eau sanitaire et de chauffage par un système de connexion rapide à épingle. Les orifices 34, 41 reliés à l'échangeur sanitaire 12 comportent une portée permettant l'immobilisation de joints 57 auto-centreurs et auto-étanches.Furthermore, the hydraulic distributor valve 14 has a return port 41 of the domestic heat exchanger 12 which is positioned on a third transverse body 42 by compared to the first 20 and second 21 bodies. This third body 42, in particular of circular cross section, came of manufacturing with the previous ones and leads into said first body 20, the latter also being provided with a orifice 43 for the output of the heating circuit. This orifice 43 forms a nozzle which can be connected to the pipe correspondent for the sanitary water production system and heating by a quick connection system with a pin. The orifices 34, 41 connected to the sanitary exchanger 12 have a span allowing immobilization of joints 57 self-centering and self-sealing.

En se reportant maintenant à la figure 3, on distingue l'intérieur du premier corps 20 de la vanne 14 au sein de laquelle un train de clapet 26 dont l'une des extrémités est fixée à un clapet 44 à double contact, mobile entre deux sièges de clapet 27, 28, l'autre extrémité étant reliée au moteur hydraulique 15. Suivant la position du clapet à double contact par rapport aux sièges de clapet 27 et 28, ceci permet d'ouvrir et de fermer des orifices situés au sein de la vanne 14 et de déterminer soit le mode de fonctionnement sanitaire, soit le mode de fonctionnement chauffage.Referring now to Figure 3, we distinguishes the interior of the first body 20 of the valve 14 at within which a valve train 26 of which one of ends fixed to a movable double contact valve 44 between two valve seats 27, 28, the other end being connected to the hydraulic motor 15. Depending on the position of the double-contact valve in relation to valve seats 27 and 28, this makes it possible to open and close orifices located within valve 14 and determine either the mode of sanitary operation, i.e. the operating mode heater.

Ainsi, sur la figure 1, le train de clapet 26 obture le siège de clapet 27 en relation avec le circuit de retour eau chaude de chauffage et met en contact thermique, grâce à 28, le circuit primaire eau chaude 5, grâce à l'échangeur sanitaire 12, avec le circuit sanitaire 13.Thus, in Figure 1, the valve train 26 closes the valve seat 27 in relation to the return circuit heating hot water and thermal contact, thanks to 28, the primary hot water circuit 5, thanks to the exchanger sanitary 12, with sanitary circuit 13.

En figure 3 est représenté le mode de fonctionnement chauffage, le train de clapet 26 obture le siège 28 et libère le siège 27 ; le circuit eau chaude 5 en aval de l'échangeur principal 3, comprenant en série au moins un radiateur 17, est mis en relation avec l'orifice 43 de la vanne hydraulique 14 reliée par le biais de la conduite 18 à l'amont de l'échangeur principal 3 après passage dans le circulateur 10 (cf. figure 1).In Figure 3 is shown the operating mode heating, the valve train 26 closes the seat 28 and releases seat 27; the hot water circuit 5 downstream of the main exchanger 3, comprising in series at least one radiator 17, is connected with the orifice 43 of the hydraulic valve 14 connected via line 18 to upstream of the main exchanger 3 after passing through the circulator 10 (see Figure 1).

Le train de clapet 26 permet en outre de délimiter dans la vanne 14 deux zones : une zone hors d'eau (partie supérieure de la vanne reliée au moteur hydraulique 15) et une zone en eau (zone inférieure de la vanne 14 comportant les premières extrémités 22, 23 des premier 20 et second 21 corps). Pour réaliser cette étanchéité entre les deux zones, on interpose un dispositif d'étanchéité et de protection d'axe 46, comprenant au moins un manchon 45 monté coaxial par rapport au train de clapet 26.The valve train 26 also makes it possible to delimit in the valve 14 two zones: a zone without water (part upper of the valve connected to the hydraulic motor 15) and a water zone (lower zone of valve 14 comprising the first ends 22, 23 of the first 20 and second 21 body). To achieve this seal between the two zones, a sealing and protection device is interposed of axis 46, comprising at least one sleeve 45 mounted coaxially relative to the valve train 26.

Le dispositif d'étanchéité et de protection d'axe 46 est complété par la présence d'une pluralité d'organes d'étanchéités, tels que notamment des joints toriques 60, des presse-étoupes 61 autour de l'axe du train de clapet 26, qui permettent de rendre hors d'eau la partie supérieure de la vanne 14.The shaft sealing and protection device 46 is complemented by the presence of a plurality of organs seals, such as in particular O-rings 60, cable glands 61 around the axis of the valve train 26, which allow the upper part of valve 14.

Le moteur hydraulique représenté en coupe sur la figure 3 et en perspective sur la figure 4 comprend une enceinte 47 divisée, par une membrane 48, en une chambre amont 49 et une chambre aval 50, la chambre amont 49 étant soumise à la pression régnant dans la conduite d'entrée d'eau froide 1, en amont de moyens de restriction 16 positionnés dans le circuit eau froide provocant, lors du passage de l'eau froide, une différence de pression dans la conduite d'entrée, et la chambre aval 50 étant en communication fluidique avec les moyens de restriction 16 pour être soumise à la pression régnant dans la conduite d'entrée d'eau froide 1, en aval desdits moyens 16, ladite membrane 48 étant déplaçable sous l'effet de la différence de pression existant entre lesdites chambres 49, 50 amont et aval et, le déplacement de la membrane 48 étant transmis à l'axe 51 de la vanne 14 puis au train de clapet 26.The hydraulic motor shown in section on the Figure 3 and in perspective in Figure 4 includes a enclosure 47 divided, by a membrane 48, into a chamber upstream 49 and a downstream chamber 50, the upstream chamber 49 being subject to pressure in the inlet line cold water 1, upstream of restriction means 16 positioned in the provocative cold water circuit, when cold water passage, a pressure difference in the inlet pipe, and the downstream chamber 50 being in fluid communication with the restriction means 16 to be subjected to the pressure prevailing in the pipe cold water inlet 1, downstream of said means 16, said membrane 48 being displaceable under the effect of the difference pressure existing between said chambers 49, 50 upstream and downstream and, the displacement of the membrane 48 being transmitted to the axis 51 of the valve 14 then to the valve train 26.

Par ailleurs (cf. figure 4), le moteur hydraulique 15 comporte d'une part, une virole de connexion 52 au premier corps 20 et d'autre part, l'enceinte 47 dont la chambre amont 49 est reliée au système générateur de différence de pression 29 grâce à une conduite 53 venue de fabrication avec la chambre amont 49, cette conduite 53 traversant la chambre aval 50 dans une zone située en périphérie de ladite membrane 48.In addition (see Figure 4), the hydraulic motor 15 comprises on the one hand, a connection ferrule 52 to the first body 20 and on the other hand, the enclosure 47 whose upstream chamber 49 is connected to the generator system pressure difference 29 thanks to a pipe 53 coming from manufacturing with the upstream chamber 49, this pipe 53 crossing the downstream chamber 50 in an area located periphery of said membrane 48.

La conduite 53 reliée à la chambre amont 49 coopère avec la prise de pression 38 réalisée au niveau du système générateur 29 de différence de pression et plus particulièrement encore au niveau de la zone haute pression des moyens de restriction 16 lorsque la virole 52 du moteur hydraulique 15 est montée sur la vanne 14.Line 53 connected to the upstream chamber 49 cooperates with the pressure tap 38 made at the system level pressure difference generator 29 and more particularly still in the high pressure area restriction means 16 when the ferrule 52 of the engine hydraulic 15 is mounted on valve 14.

Une conduite 54 venue de fabrication avec la chambre aval 50 communique avec la prise de pression 39 dite de basse pression réalisée dans le système générateur 29, et plus précisément au niveau d'une zone en aval du clapet 35.A pipe 54 coming from manufacturing with the chamber downstream 50 communicates with the pressure tap 39 called low pressure produced in the generator system 29, and more precisely at a level downstream of the valve 35.

Comme on peut le remarquer sur la figure 2, l'axe 51 du train de clapet 26 est parallèle aux axes des prises de pression 38, 39 du système générateur de différence de pression 29, lorsque le moteur hydraulique est monté, par l'intermédiaire de la virole de connexion 52, sur le corps de la vanne 14, à l'aide d'un système de montage rapide à épingle.As can be seen in Figure 2, the axis 51 of the valve train 26 is parallel to the axes of the taps pressure 38, 39 of the difference generating system pressure 29, when the hydraulic motor is mounted, by via the connection ring 52, on the body of valve 14, using a quick mounting system to pin.

La virole de connexion 52 est venue de fabrication avec l'enceinte 47 et est réalisée par une technique de moulage d'une matière plastique, similaire à celle utilisée pour la fabrication de la vanne 14. Cette virole 52 est munie d'une ouverture 55 permettant le passage d'un capteur 56 de détection de la course et/ou de la position du train de clapet 26 au sein du premier corps 20. Ce capteur 56 détecte le mouvement d'une partie en saillie positionnée à l'extrémité du train clapet 26 et en dessous de la partie d'axe reliée à la membrane 48.Connection ferrule 52 came from manufacturing with enclosure 47 and is made by a technique of plastic molding, similar to that used for the manufacture of valve 14. This ferrule 52 is provided with an opening 55 allowing the passage of a sensor 56 for detecting the travel and / or the position of the train valve 26 within the first body 20. This sensor 56 detects the movement of a projecting part positioned at the end of the valve train 26 and below the part axis connected to the membrane 48.

En raison de la présence du dispositif d'étanchéité et de protection 46 du train de clapet 26 entre la zone inférieure et la zone supérieure de la vanne 14, et du dispositif d'étanchéité 59 présent sur l'axe 51 qui coopère avec la membrane 48 dans l'enceinte 47, il n'y a pas de risque de fuite au niveau de l'ouverture 55.Due to the presence of the sealing device and protection 46 of the valve train 26 between the zone lower and upper area of valve 14, and of sealing device 59 present on the axis 51 which cooperates with the membrane 48 in the enclosure 47, there is no risk of leakage at the opening 55.

L'invention telle que décrite précédemment offre de multiples avantages :

  • les systèmes de connexion rapide à épingle facilitent le montage et le démontage des divers éléments sur la vanne, ce qui représente un gain de temps appréciable lors des opérations de maintenance ;
  • il est aisé de changer des pièces de l'installation, sans risque d'erreur au montage, car il devient possible d'incorporer des détrompeurs au système de connexion rapide.
The invention as described above offers multiple advantages:
  • the quick connection pin systems facilitate the mounting and dismounting of the various elements on the valve, which represents an appreciable time saving during maintenance operations;
  • it is easy to change parts of the installation, without risk of assembly error, because it becomes possible to incorporate keying devices to the quick connection system.
