Description

L'invention concerne une vanne d'installation de chauffage, ainsi qu'une installation de chauffage central et un radiateur comportant au moins une telle vanne.The invention relates to a valve for installing heating, as well as a central heating and a radiator comprising at least one such valve.

Dans les installations de chauffage ou dans les installations sanitaires, les vannes servent à réguler le débit d'eau chaude ou froide circulant dans les canalisations, ou servent de robinet d'écoulement. Une vanne comporte un corps de vanne, et un obturateur interne commandé pour obturer ou ouvrir le corps de vanne. Cet obturateur interne est commandé par un dispositif thermostatique ou manuel de commande.In heating systems or in sanitary facilities, the valves are used to regulate the water flow hot or cold circulating in the pipes, or serve as a tap of flow. A valve has a valve body and a shutter internal control to close or open the valve body. This internal shutter is controlled by a thermostatic device or control manual.

Selon une exécution connue décrite dans le document de brevet IT-A-1183037, la vanne comprend un obturateur qui prend appui sur un épaulement, de part et d'autre duquel se trouvent d'une part une chambre interne et une chambre périphérique du corps de vanne et d'autre part un conduit.According to a known embodiment described in the document of patent IT-A-1183037, the valve includes a shutter which is supported on a shoulder, on both sides of which are on the one hand a internal chamber and a peripheral chamber of the valve body and on the other hand a conduit.

En général, l'orientation de la vanne est déterminée par la position du dispositif de commande par rapport à l'appareil de chauffage ou à l'appareil sanitaire sur lequel la vanne est montée. Par exemple, dans le cas des vannes thermostatiques, le dispositif de commande thermostatique doit, en général, s'étendre horizontalement. Et, généralement, les appareils de chauffage ou les appareils sanitaires sont fixés à proximité de murs verticaux, les canalisations destinées à être reliées à l'appareil débouchant du sol ou du mur à proximité de l'appareil. Le problème qui se pose donc généralement est celui du raccordement de la ou des canalisations à la vanne dès lors que ni l'orientation de l'extrémité libre de la canalisation ni celle de la vanne ne peuvent être modifiées à volonté. En effet, ce raccordement nécessite un temps de montage important, et l'utilisation de pièces de raccordement (coude, té...) nombreuses et volumineuses.In general, the orientation of the valve is determined by the position of the control device in relation to the heater or to the sanitary appliance on which the valve is mounted. For example, in the case of thermostatic valves, the control device In general, the thermostat should extend horizontally. And, generally, heaters or fixtures are fixed near vertical walls, the pipes intended to be connected to the device emerging from the floor or wall near the device. The problem which therefore generally arises is that of connection of the pipe (s) to the valve when neither the orientation of the free end of the pipe or that of the valve cannot be changed at will. Indeed, this connection requires a significant assembly time, and the use of parts numerous and voluminous connections (elbow, tee ...).

Par ailleurs, il arrive fréquemment que des raccordements encastrés dans les murs ou les sols doivent être réalisés pour relier un appareil sanitaire ou de chauffage à une canalisation. En particulier, le raccordement d'un appareil en parallèle à une canalisation est généralement effectué encastré dans le sol ou dans les murs. Or, un tel raccordement encastré pose des problèmes de fiabilité et de sécurité.In addition, it often happens that connections embedded in walls or floors must be made to connect a sanitary appliance or heating to a pipe. In particular, the connection of a device in parallel to a pipe is generally carried out embedded in the ground or in walls. However, such a recessed connection poses problems reliability and security.

L'invention vise donc à remédier à ces inconvénients et a pour objet de proposer une vanne pour installation de chauffage permettant de modifier l'orientation par rapport au corps de vanne d'au moins une canalisation à laquelle elle est reliée, et qui soit par ailleurs d'un encombrement extrêmement faible et ne nécessite pas de pièce de raccordement spécifique. L'invention vise en particulier également à proposer une telle vanne qui comporte un nombre minimum de pièces et avec laquelle le montage s'effectue de façon simple et rapide.The invention therefore aims to remedy these drawbacks and aims to propose a valve for installation of heating to change the orientation relative to the valve body of at least one pipe to which it is connected, and which is otherwise of a extremely small footprint and does not require specific connection piece. The invention aims at also particularly to propose such a valve which contains a minimum number of parts and with which the mounting is quick and easy.

L'invention vise également à proposer une telle vanne grâce à laquelle le raccordement de la vanne en parallèle à une canalisation peut être réalisé directement sur cette vanne.The invention also aims to propose such a valve whereby the connection of the valve in parallel to a pipeline can be made directly on this valve.

L'invention vise également à proposer une telle vanne qui soit plus particulièrement appropriée au raccordement à au moins une canalisation en matière plastique semi-rigide telle que le PVC réticulé.The invention also aims to propose such a valve which is more particularly suitable for connection to at least one semi-rigid plastic pipe such as crosslinked PVC.

L'invention vise également à proposer une telle vanne qui soit plus particulièrement appropriée pour réaliser une vanne thermostatique d'installation de chauffage central.The invention also aims to propose such a valve which is more particularly suitable for carrying out a thermostatic valve for central heating installation.

L'invention vise également à proposer une installation de chauffage central comprenant au moins une canalisation et au moins un appareil sanitaire ou de chauffage relié à la canalisation sans aucun raccordement encastré dans le sol ou les murs. En particulier, l'invention vise à proposer une telle installation dans laquelle l'appareil peut être relié en parallèle à la canalisation.The invention also aims to provide a central heating system including at least one pipe and at least one sanitary appliance or heating connected to the pipeline without any recessed connection in the floor or walls. In particular, the invention aims to propose such a installation in which the device can be connected in parallel to the pipeline.

L'invention vise également à proposer une installation de chauffage central exempte de raccordement encastré, dont les canalisations peuvent être en matière plastique semi-rigide telle que le PVC réticulé, dont le coût de fabrication et de montage est faible et dont l'équilibrage peut être réalisé aisément.The invention also aims to propose an installation for central heating free of recessed connection, the pipes can be made of semi-rigid plastic such as Crosslinked PVC, which has a low manufacturing and assembly cost and whose balancing can be carried out easily.

Enfin, l'invention vise à proposer un radiateur d'installation de chauffage central dont le montage et le raccordement aux canalisations de chauffage est simple et rapide.Finally, the invention aims to propose a radiator central heating installation including mounting and connection to the heating pipes is simple and quick.

Pour ce faire, l'invention concerne une vanne d'installation de chauffage comprenant les caractéristiques de la revendication 1.To do this, the invention relates to a valve heating installation comprising the features of claim 1.

Selon l'invention, le corps de vanne comporte un diaphragme interne dans lequel est ménagé chaque orifice en communication avec un alésage axial du diaphragme ouvert du côté de l'obturateur, ainsi qu'au moins un transfert longitudinal du diaphragme mettant en communication la chambre du corps avec une extrémité débouchante du corps, de sorte que l'eau peut librement circuler autour de la portion cylindrique en passant par les orifices pour aboutir dans la chambre, l'obturateur étant commandé en translation axiale par rapport au corps de vanne pour venir au contact du diaphragme interne et obturer l'alésage axial, ou pour s'en écarter et l'ouvrir.According to the invention, the valve body includes a internal diaphragm in which each orifice is formed in communication with an axial bore of the diaphragm open on the side of the shutter, as well as at least one longitudinal transfer of the diaphragm connecting the chamber of the body with one end emerging from the body, so that water can circulate freely around of the cylindrical portion passing through the orifices to end up in the chamber, the shutter being controlled in axial translation relative to to the valve body to come into contact with the internal diaphragm and seal the axial bore, or to deviate from it and open it.

Selon l'invention, le machon comporte au moins un orifice communiquant d'une part avec chaque orifice de la portion cylindrique, et d'autre part avec au moins un tube de raccordement destiné à être relié à une canalisation d'une installation de chauffage central, exempte de raccordement dans le sol ou les murs, tandis que la portion cylindrique du corps de vanne s'étend d'un côté et au-delà du diaphragme et l'obturateur est monté sur un support d'obturateur associé à une extrémité libre du corps de vanne.According to the invention, the machon comprises at least one orifice communicating on the one hand with each orifice of the portion cylindrical, and on the other hand with at least one connecting tube intended to be connected to a pipe of a heating installation central, free of connection in the ground or walls, while the cylindrical portion of the valve body extends on one side and beyond the diaphragm and the shutter is mounted on an associated shutter support at a free end of the valve body.

Selon l'invention, le support est vissé dans un taraudage interne du corps de vanne.According to the invention, the support is screwed into a thread internal of the valve body.

Selon l'invention, chaque tube de raccordement est coudé dans la direction axiale du corps de vanne.According to the invention, each connection tube is bent in the axial direction of the valve body.

Selon l'invention, le manchon comporte deux orifices et deux tubes de raccordement.According to the invention, the sleeve has two openings and two connection tubes.

Par ailleurs, selon l'invention, le corps de vanne comporte une extrémité débouchante d'écoulement ou de raccordement à une canalisation d'un appareil. Ainsi, le corps de vanne constitue soit l'extrémité d'écoulement d'un robinet ou comporte un filetage externe de raccordement à une canalisation d'un appareil.Furthermore, according to the invention, the valve body comprises an outlet end of flow or connection to a channeling of a device. Thus, the valve body constitutes either the outlet end of a tap or has an external thread of connection to a device pipe.

Selon l'invention, la portion cylindrique s'étend entre cette extrémité débouchante et un épaulement externe périphérique contre lequel le manchon vient en appui.According to the invention, the cylindrical portion extends between this through end and a peripheral external shoulder against which the sleeve bears.

Par ailleurs, l'extrémité débouchante comporte un filetage externe de raccordement et la vanne comporte un joint d'étanchéité de chaque côté du manchon serré lors du vissage du filetage externe entre la canalisation de l'appareil et l'épaulement lors du vissage du filetage externe. En variante, le manchon est serré par un écrou vissé sur le filetage externe.Furthermore, the through end has a thread external connection and the valve has a gasket of each side of the sleeve tightened when screwing the external thread between the pipe of the device and the shoulder when screwing the thread external. Alternatively, the sleeve is tightened by a nut screwed onto the external thread.

La figure 1 représente une vanne thermostatique 1 d'alimentation d'un radiateur selon l'invention qui comprend un corps de vanne 2, et un obturateur interne 4 commandé pour obturer ou ouvrir le corps de vanne 2. Le corps de vanne 2 comporte une portion cylindrique 3 munie de deux orifices 5 débouchant à la surface extérieure 23 de la portion cylindrique 3 et communiquant avec l'obturateur 4. Un manchon 6 de raccord, de forme globalement torique, entoure la portion cylindrique 3 et définit une chambre de circulation 7 périphérique annulaire autour de la portion cylindrique 3 et de ses orifices 5. Cette chambre de circulation 7 périphérique annulaire met en communication chaque orifice 5 de la portion cylindrique 3 avec au moins un orifice 8 du manchon 6. Figure 1 shows a thermostatic valve 1 supply of a radiator according to the invention which includes a valve body 2, and an internal shutter 4 controlled to close or open the valve body 2. The valve body 2 has a cylindrical portion 3 provided of two orifices 5 opening onto the outer surface 23 of the cylindrical portion 3 and communicating with the shutter 4. A coupling sleeve 6, of generally toroidal shape, surrounds the cylindrical portion 3 and defines a circulation 7 ring device around the portion cylindrical 3 and its orifices 5. This chamber circulation 7 ring device ports each orifice 5 of the cylindrical portion 3 with at least an orifice 8 of the sleeve 6.

Dans le mode de réalisation représenté sur la figure 1, le corps de vanne 2 comporte un diaphragme 9 interne et l'obturateur 4 est commandé en translation axiale par rapport au corps de vanne 2 pour venir au contact du diaphragme 9 interne et l'obturer ou pour s'en écarter et l'ouvrir. L'obturateur 4 est monté sur un arbre axial 24 d'obturateur lui-même monté sur un support 10 d'obturateur associé à une extrémité libre 11 du corps de vanne 2. La portion cylindrique 3 du corps de vanne 2 s'étend d'un côté et au delà du diaphragme 9, et les orifices 5 communiquent avec le diaphragme 9 du côté opposé à l'obturateur 4.In the embodiment shown in the figure 1, the valve body 2 has an internal diaphragm 9 and the shutter 4 is controlled in axial translation by relative to valve body 2 to come into contact with the internal diaphragm 9 and seal it or to deviate from it and open it. The shutter 4 is mounted on an axial shaft 24 shutter itself mounted on a shutter support 10 associated with a free end 11 of the valve body 2. The cylindrical portion 3 of the valve body 2 extends on one side and beyond the diaphragm 9, and the orifices 5 communicate with the diaphragm 9 on the side opposite the shutter 4.

Le support 10 d'obturateur est vissé dans un taraudage 12 interne ménagé à l'extrémité 11 du corps de vanne 2. Ce support 10 d'obturateur guide l'arbre d'obturateur 24 en translation axiale en le rappelant dans sa position écartée du diaphragme 9, et porte un dispositif de commande thermostatique 25 connu en lui-même et représenté uniquement partiellement et schématiquement sur la figure 1.The shutter support 10 is screwed into a internal thread 12 formed at the end 11 of the body valve 2. This shutter support 10 guides the shaft shutter 24 in axial translation by recalling it in its position away from the diaphragm 9, and carries a device thermostatic control 25 known in itself and represented only partially and schematically on Figure 1.

L'arbre 24 d'obturateur coulisse en translation axiale selon un axe 20 de translation qui est confondu avec l'axe central du diaphragme 9, lui-même confondu avec l'axe central du corps de vanne 2 et de la portion cylindrique 3. Les orifices 5 débouchant de la portion cylindrique 3 sont constitués dans le mode de réalisation de la figure 1 d'un perçage radial 26 traversant la portion cylindrique 3 de part en part pour communiquer avec un alésage axial 27 s'étendant du côté de l'obturateur 4 pour former l'ouverture du diaphragme 9. Ainsi, chaque orifice 5 de la portion cylindrique 3 est en communication avec le diaphragme 9 du côté opposé à l'obturateur 4.The shutter shaft 24 slides in translation axial along an axis 20 of translation which is coincident with the central axis of the diaphragm 9, itself coincident with the axis center of valve body 2 and of cylindrical portion 3. The orifices 5 emerging from the cylindrical portion 3 are constituted in the embodiment of Figure 1 of a radial bore 26 passing through the cylindrical portion 3 of right through to communicate with an axial bore 27 extending from the shutter side 4 to form the opening of the diaphragm 9. Thus, each orifice 5 of the cylindrical portion 3 is in communication with the diaphragm 9 on the side opposite the shutter 4.

Le corps de vanne 2 comporte une extrémité 14 débouchante d'écoulement ou de raccordement à l'appareil ou à une canalisation 15 du radiateur ou de l'appareil, et la portion cylindrique 3 s'étend entre cette extrémité 14 débouchante et un épaulement 16 externe périphérique contre lequel le manchon 6 vient en appui axialement.The valve body 2 has one end 14 drain outlet or connection to the appliance or to a pipe 15 of the radiator or of the appliance, and the cylindrical portion 3 extends between this end 14 opening and a peripheral external shoulder 16 against which the sleeve 6 comes to bear axially.

L'obturateur 4 s'étend et se déplace dans une chambre 22 d'obturateur ménagée dans le corps de vanne 2. Cette chambre 22 est délimitée à l'extrémité 11 du corps de vanne 2 opposée à l'extrémité débouchante 14 entre le diaphragme 9 et l'extrémité 29 filetée du support d'obturateur 10 engagé dans le taraudage 12 du corps de vanne 2. Et le diaphragme 9 comporte au moins un transfert 28 - notamment deux transferts 28a, 28b symétriques l'un de l'autre par rapport à l'axe 20 - longitudinal mettant en communication la chambre 22 d'obturateur avec l'extrémité débouchante 14 du corps de vanne 2.The shutter 4 extends and moves in a room 22 shutter formed in the valve body 2. This chamber 22 is delimited at the end 11 of the valve body 2 opposite the through end 14 between the diaphragm 9 and the threaded end 29 of the shutter support 10 engaged in the internal thread 12 of the valve body 2. And the diaphragm 9 includes at least one transfer 28 - in particular two transfers 28a, 28b symmetrical to each other by relative to axis 20 - longitudinal connecting the shutter chamber 22 with the through end 14 valve body 2.

L'extrémité 14 débouchante du corps de vanne comporte un filetage externe 17 de raccordement à la canalisation 15 solidaire de l'appareil (ou à l'appareil lui-même directement), et la vanne 1 comporte un joint d'étanchéité 18 interposé entre le manchon 6 et la canalisation 15 de l'appareil (ou l'appareil), et un joint d'étanchéité 19 interposé entre le manchon 6 et l'épaulement, le manchon 6 et les joints 18, 19 étant serrés entre la canalisation 15 de l'appareil (ou l'appareil) et l'épaulement lors du vissage du filetage externe 17 dans le taraudage de la canalisation 15 (ou de l'appareil). Le filetage externe 17 et l'extrémité débouchante 14 s'étendent axialement dans la même direction que l'axe 20 de translation de l'obturateur 4.The end 14 emerging from the valve body comprises an external thread 17 for connection to the pipe 15 secured to the device (or to the device itself directly), and valve 1 has a seal 18 interposed between the sleeve 6 and the pipe 15 of the device (or device), and a seal 19 interposed between the sleeve 6 and the shoulder, the sleeve 6 and the seals 18, 19 being clamped between the pipe 15 of the device (or device) and the shoulder when screwing the external thread 17 into the thread of the line 15 (or of the device). External thread 17 and the through end 14 extend axially in the same direction as the axis 20 of translation of the shutter 4.

Comme on le voit sur la figure 3 les transferts 28a, 28b longitudinaux s'étendent de chaque côté du perçage radial 26 et de l'alésage axial 27 dans la portion cylindrique 3 pour mettre en communication la chambre 22 d'obturateur avec un alésage débouchant 31 de l'extrémité 14 débouchante du corps de vanne 2. Cet alésage 31 est obturé par une paroi transversale 49 du corps de vanne qui sépare l'alésage 31 du perçage radial 26 et de l'alésage axial 27, les transferts 28a, 28b débouchant latéralement au niveau de cette paroi 49. Sur les figures 1, 2 et 3 le cheminement de l'eau a été représenté par des flèches. Sur la figure 1, l'obturateur 4 est en position d'obturation alors que sur la figure 2, il a été représenté en position écartée du diaphragme 9, le corps de vanne 2 étant ouvert.As we see in Figure 3 the transfers 28a, 28b longitudinal extend on each side of the bore radial 26 and axial bore 27 in the portion cylindrical 3 for connecting the chamber 22 obturator with a bore opening 31 from the end 14 through the valve body 2. This bore 31 is closed by a transverse wall 49 of the valve body which separates the bore 31 from the radial bore 26 and the bore axial 27, transfers 28a, 28b opening laterally at the level of this wall 49. In FIGS. 1, 2 and 3 the water path has been represented by arrows. Sure Figure 1, the shutter 4 is in the closed position whereas in FIG. 2, it has been shown in position spaced from the diaphragm 9, the valve body 2 being open.

Le manchon 6 est de forme globalement torique dont la section de génération du tore est en forme de U dont l'ouverture est orientée vers l'axe 20. Ainsi, l'âme 32 du U définit une paroi cylindrique externe du manchon 6 écartée de la surface extérieure 23 de la portion cylindrique 3, et les ailes 33 du U s'étendent radialement pour former des couronnes dont le bord interne correspondant à l'extrémité de l'aile 33 vient au contact de la surface extérieure 23 de la portion cylindrique 3. La chambre de circulation 7 est ainsi ménagée entre la surface extérieure 23 de la portion cylindrique 3, les ailes 33 et l'âme 32 du manchon 6. Dès lors, l'eau peut librement circuler autour de la portion cylindrique 3 dans la chambre 7 de circulation.The sleeve 6 is generally toroidal in shape, the torus generation section is U-shaped whose the opening is oriented towards the axis 20. Thus, the core 32 of the U defines an external cylindrical wall of the sleeve 6 away from the outer surface 23 of the portion cylindrical 3, and the wings 33 of the U extend radially to form crowns with an internal edge corresponding to the end of wing 33 comes into contact of the outer surface 23 of the cylindrical portion 3. The circulation chamber 7 is thus formed between the surface outer 23 of the cylindrical portion 3, the wings 33 and the core 32 of the sleeve 6. Consequently, the water can freely circulate around the cylindrical portion 3 in the chamber 7 circulation.

Chaque orifice 8 du manchon 6 met la chambre de circulation 7 en communication avec au moins un tube 13 de raccordement - notamment avec deux tubes de raccordement 13a, 13b - destiné à être relié à une canalisation d'une installation de chauffage central. Dans le mode de réalisation représenté sur les figures et selon l'invention, chaque tube de raccordement 13 est coudé dans la direction axiale du corps de vanne 2, c'est-à-dire pour s'étendre parallèlement à l'axe 20 et à l'extrémité 14 débouchante du corps de vanne 2. Egalement, dans les modes de réalisation représentés et selon l'invention, le manchon 6 comporte avantageusement deux orifices 8a, 8b, communiquant avec la chambre 7 de circulation et deux tubes de raccordement 13a, 13b de façon à pouvoir raccorder directement le manchon 6 et la vanne selon l'invention en parallèle à la canalisation de l'installation de chauffage qui entre dans la vanne par l'un 13a des tubes de raccordement et sort de la vanne par l'autre 13b des tubes de raccordement. Bien évidemment, le manchon 6 peut ne comporter qu'un seul tube 13 de raccordement, notamment dans le cas où la vanne est destinée à être montée à l'extrémité d'une canalisation. La vanne thermostatique 1 représentée sur les figures 1 à 3 est une vanne d'alimentation, c'est-à-dire que l'eau arrive dans la vanne par l'un 13a des tubes de raccordement, et s'en échappe par l'autre tube 13b de raccordement et par l'extrémité 14 débouchante si l'obturateur 4 est en position d'ouverture. Ainsi, le débit d'eau dans le tube de raccordement de sortie 13b est égal au débit d'eau dans le tube de raccordement d'entrée 13a diminué du débit d'eau entrant dans l'appareil par l'extrémité 14 débouchante. La vanne 1 thermostatique est extrêmement compacte, permet de laisser le dispositif 25 thermostatique en position parfaitement horizontale, parallèle au mur 34 représenté sur la figure 1 et peut être installée instantanément sur la canalisation 15 de l'appareil lui-même ou sur l'appareil par simple vissage. L'extrémité des tubes 13 de raccordement coudés comporte également un filetage de raccordement à la canalisation de l'installation. Les tubes de raccordement 13 coudés peuvent s'étendre dans l'espace compris entre le radiateur et le mur 34. Le manchon 6 peut être tourné autour de l'axe 20 dans la position adéquate pour le raccordement des tubes 13 de raccordement à la canalisation de l'installation avant le serrage de la vanne sur l'appareil. Each orifice 8 of the sleeve 6 places the circulation 7 in communication with at least one tube 13 of connection - in particular with two connection tubes 13a, 13b - intended to be connected to a pipe of a central heating installation. In the embodiment shown in the figures and according to the invention, each connecting tube 13 is bent in the axial direction of the valve body 2, that is to say for extend parallel to axis 20 and end 14 through the valve body 2. Also, in the modes shown and according to the invention, the sleeve 6 advantageously comprises two orifices 8a, 8b, communicating with the circulation chamber 7 and two tubes 13a, 13b so that you can connect directly the sleeve 6 and the valve according to the invention in parallel to the installation pipeline heater which enters the valve through one of the tubes 13a connection and exit from the valve through the other 13b of connecting tubes. Obviously, the sleeve 6 can have only one connection tube 13, in particular in the case where the valve is intended to be mounted at the end of a pipeline. Thermostatic valve 1 shown in Figures 1 to 3 is a valve supply, i.e. water enters the valve by one 13a of the connection tubes, and escapes by the other connecting tube 13b and through the end 14 opening if the shutter 4 is in the open position. Thus, the water flow in the connection tube of outlet 13b is equal to the water flow in the tube inlet connection 13a reduced in incoming water flow in the device by the end 14 opening out. Valve 1 thermostatic is extremely compact, allows to leave the thermostatic device 25 in perfect position horizontal, parallel to the wall 34 shown in Figure 1 and can be installed instantly on the pipeline 15 of the device itself or on the device by simple screwing. The end of the angled connection tubes 13 also includes a thread for connection to the installation pipeline. Connection tubes 13 cubits can extend into the space between the radiator and wall 34. Sleeve 6 can be rotated around axis 20 in the proper position for the connection of the tubes 13 for connection to the pipeline of the installation before tightening the valve on the device.

Le corps de vanne 2 est constitué d'une pièce d'un seul tenant recevant le support d'obturateur 10 et le manchon 6. La vanne 1 est donc essentiellement constituée de trois pièces et des joints 18, 19. Un joint 35 est également interposé entre le support d'obturateur 10 et le corps de vanne 2. The valve body 2 consists of a part of a in one piece receiving the shutter support 10 and the sleeve 6. The valve 1 is therefore essentially constituted of three parts and seals 18, 19. A seal 35 is also interposed between the shutter support 10 and the valve body 2.

Bien évidemment, les tubes de raccordement 13 ne sont pas nécessairement coudés et peuvent être simplement constitués des filetages de raccordement à la canalisation de l'installation s'étendant dans un plan radial.Obviously, the connection tubes 13 are not not necessarily angled and can be simply consisting of threads connecting to the pipeline of the installation extending in a radial plane.

Dans les vannes 1 et 36 représentées sur les figures, la pression d'eau sur l'obturateur 4 tend à ouvrir spontanément cet obturateur 4. Cela est en effet indispensable dans les vannes thermostatiques dont l'obturateur 4 est rappelé en position d'ouverture par un ressort afin d'éviter que l'obturateur 4 ne colle au diaphragme 9.In valves 1 and 36 shown in the figures, the water pressure on the shutter 4 tends to open spontaneously this shutter 4. This is indeed essential in thermostatic valves including the shutter 4 is returned to the open position by a spring to prevent the shutter 4 from sticking to the diaphragm 9.

Une vanne selon l'invention peut également comporter plusieurs portions cylindriques 3 et plusieurs manchons 6, voire même plusieurs obturateurs 4 selon les types de raccordement souhaités.A valve according to the invention can also include several cylindrical portions 3 and several sleeves 6, or even several shutters 4 depending on the types of desired connection.

La figure 4 représente un exemple de réalisation d'une installation de chauffage central selon l'invention qui comprend au moins une canalisation 43, 44 et au moins un appareil 45 relié à la canalisation 43, 44 par une vanne 1 ou 36 selon l'invention. La canalisation 43, 44 d'une telle installation selon l'invention peut être en matière plastique semi-rigide - notamment en PVC réticulé - et être exempte de raccordement encastré dans le sol 46 ou dans les murs 34, le raccordement de la vanne en parallèle à la canalisation s'effectuant directement sur la vanne elle-même qui comporte deux tubes de raccordement 13a, 13b. L'installation de chauffage central de la figure 5 comprend une canalisation d'alimentation 43 en provenance d'une chaufferie ou d'une nourrice 47 et une canalisation de retour 44 à la chaufferie ou à la nourrice 47, et au moins un radiateur 45 muni d'au moins une vanne 1 ou 36 selon l'invention. En particulier, chaque radiateur 45 comporte une vanne d'alimentation 1 ou 36 selon l'invention.Figure 4 shows an exemplary embodiment of a central heating installation according to the invention which comprises at least one pipe 43, 44 and at least an apparatus 45 connected to the pipe 43, 44 by a valve 1 or 36 according to the invention. Line 43, 44 of such an installation according to the invention can be in semi-rigid plastic - especially cross-linked PVC - and be free from embedded connections in the ground 46 or in walls 34, the valve connection in parallel to the piping taking place directly on the valve itself which comprises two connection tubes 13a, 13b. The central heating installation of Figure 5 includes a supply line 43 coming from a boiler room or nurse 47 and a pipeline from return 44 to the boiler room or nurse 47, and at least a radiator 45 provided with at least one valve 1 or 36 according to the invention. In particular, each radiator 45 comprises a supply valve 1 or 36 according to the invention.

Chaque radiateur 45 est relié à la canalisation d'alimentation 43 en parallèle par une vanne d'alimentation 1 à deux tubes de raccordement 13a, 13b à l'exception du dernier radiateur 45c - c'est-à-dire du radiateur le plus en aval sur la canalisation d'alimentation 43 - qui comporte une vanne d'alimentation 1 ayant uniquement un tube de raccordement 13. En effet, pour le dernier radiateur 45c, l'intégralité du débit d'eau arrivant dans le tube de raccordement 13 doit passer à l'intérieur du radiateur 45c jusqu'à sa sortie 48c.Each radiator 45 is connected to the pipeline supply 43 in parallel by a supply valve 1 to two connection tubes 13a, 13b except for the last radiator 45c - that is to say the most downstream on the supply line 43 - which includes a supply valve 1 having only one connection tube 13. Indeed, for the last 45c radiator, the entire water flow arriving in the connection tube 13 must pass inside the radiator 45c until its outlet 48c.

Ainsi, la canalisation d'alimentation comprend une première portion 43a reliant la nourrice 47 à la vanne thermostatique 1a du premier radiateur 45a. Cette canalisation 43a est raccordée au tube de raccordement 13a d'entrée de la vanne 1a. L'extrémité débouchante de cette vanne 1a est connectée à la canalisation 15a du premier radiateur 45a. Le tube de raccordement 13b de sortie est relié à une portion intermédiaire 43b de la canalisation d'alimentation qui relie continûment et sans raccord cette vanne d'alimentation 1a à la vanne d'alimentation 1b d'un radiateur intermédiaire 45b. La canalisation intermédiaire 43b en provenance du premier radiateur 45a est donc reliée au tube de raccordement 13a d'entrée de la vanne thermostatique 1b. Une autre canalisation intermédiaire d'alimentation 43b est reliée au tube de raccordement 13b de sortie de cette vanne 1b pour relier ce radiateur 45b à un radiateur subséquent intermédiaire 45b. La vanne 1b d'alimentation d'un radiateur intermédiaire 45b a son extrémité débouchante 14 connectée à la canalisation 15b du radiateur. Le dernier radiateur 45c est relié au radiateur intermédiaire 45b immédiatement en amont par une dernière portion 43c de la canalisation d'alimentation 43 qui est connectée au tube de raccordement 13 de la vanne 1c de ce dernier radiateur 45c. L'extrémité débouchante 14 de cette vanne 1c communique avec la canalisation 15c de ce dernier radiateur 45c.Thus, the supply line comprises a first portion 43a connecting the nurse 47 to the valve thermostatic 1a of the first radiator 45a. This pipe 43a is connected to connection tube 13a inlet valve 1a. The through end of this valve 1a is connected to line 15a of the first radiator 45a. The outlet connection tube 13b is connected to an intermediate portion 43b of the pipeline that connects continuously and without connection this supply valve 1a to supply valve 1b of a intermediate radiator 45b. The intermediate pipeline 43b from the first radiator 45a is therefore connected to the valve inlet connection tube 13a thermostatic 1b. Another intermediate pipeline supply 43b is connected to the connection tube 13b outlet of this valve 1b to connect this radiator 45b to a subsequent intermediate radiator 45b. Valve 1b supply of an intermediate radiator 45b to its through end 14 connected to the pipe 15b of the radiator. The last radiator 45c is connected to the radiator intermediate 45b immediately upstream with a final portion 43c of the supply line 43 which is connected to the connection tube 13 of the valve 1c of this last radiator 45c. The through end 14 of this valve 1c communicates with the pipe 15c of the latter 45c radiator.

Selon l'invention, les sorties 48 des radiateurs 45 sont reliées entre elles en parallèle, la sortie 48c du dernier radiateur 45c étant reliée à la canalisation de retour 44 jusqu'à la nourrice 47. Pour ce faire, on peut utiliser une vanne de sortie 36 à commande manuelle telle que représentée sur la figure 4. Ainsi, dans une installation selon l'invention la sortie 48 d'au moins un radiateur 45 est équipée d'une vanne de sortie selon l'invention. La première vanne de sortie 36a reliée à la sortie 48a du premier radiateur 45a, comporte un seul tube de raccordement 13 qui est relié à une première portion 44a de la canalisation de retour. Cette première portion 44a est reliée au tube de raccordement 13a d'entrée d'une vanne de sortie 36b d'un radiateur intermédiaire 45b. La sortie 48b de la canalisation 15b du radiateur intermédiaire 45b est reliée à l'extrémité de la vanne 36b, et le tube de raccordement 13b de sortie de cette vanne 36b est relié à une portion intermédiaire 44b de la canalisation de retour, et ainsi de suite jusqu'à dernier radiateur 45c dont la vanne de sortie 36c est reliée à la sortie 48c et a son tube de raccordement de sortie 13b relié à la dernière portion 44c de la canalisation de retour jusqu'à la nourrice 47. Ainsi, dans une installation selon l'invention, chaque radiateur comporte une vanne d'alimentation 1 équipée d'un dispositif thermostatique de commande 25 et une vanne de sortie 36 équipée d'un dispositif manuel de commande 37. Chaque portion de canalisation peut être constituée en matière plastique semi-rigide telle que du PVC réticulé et aucun raccordement encastré n'est nécessaire dans les murs ou dans le sol, tous les raccordements étant réalisés sur les vannes 1 ou 36. Les manchons 6 des vannes permettent de faciliter grandement l'installation et la pose des radiateurs en faisant varier légèrement l'orientation des tubes de raccordement 13.According to the invention, the outputs 48 of the radiators 45 are connected together in parallel, the output 48c of the last radiator 45c being connected to the pipe of back 44 to nurse 47. To do this, we can use a manually operated outlet valve 36 such as shown in Figure 4. So in a installation according to the invention outlet 48 of at least one radiator 45 is fitted with an outlet valve according to the invention. The first outlet valve 36a connected to the outlet 48a of the first radiator 45a, has a single tube connection 13 which is connected to a first portion 44a from the return line. This first portion 44a is connected to the inlet connection tube 13a of a outlet valve 36b of an intermediate radiator 45b. The outlet 48b from line 15b of the radiator intermediate 45b is connected to the end of the valve 36b, and the connection tube 13b for the outlet of this valve 36b is connected to an intermediate portion 44b of the return line, and so on until last radiator 45c, the outlet valve 36c of which is connected to the outlet 48c and has its outlet connection tube 13b connected to the last portion 44c of the pipeline from back to nurse 47. So in an installation according to the invention, each radiator comprises a valve supply 1 fitted with a thermostatic device control 25 and an outlet valve 36 fitted with a manual control device 37. Each portion of pipe can be made of plastic semi-rigid such as cross-linked PVC and no connection recessed is not necessary in the walls or in the ground, all connections being made on valves 1 or 36. The sleeves 6 of the valves make it possible to facilitate greatly the installation and installation of radiators in slightly varying the orientation of the connection 13.

L'invention concerne également un radiateur 45 d'installation de chauffage central qui comporte une vanne d'alimentation 1 et/ou une vanne de sortie 36 selon l'invention.The invention also relates to a radiator 45 central heating installation that includes a valve supply 1 and / or an outlet valve 36 according to the invention.
