Abstract

Hinged regulating shutter, arranged in front of the opening of a fresh air duct, supplying a central heating boiler, and whose axis of pivoting is in the plane of the opening of the duct outside of the latter, this shutter being in contact, by a cylindrical portion, with the external face of a tangential straight edge of the duct, and having a lip which faces the opening of the duct and delimits a concavity.

Description

La présente invention concerne un clapet régulateur articulé, disposé devant l'ouverture d'un conduit. The present invention relates to an articulated regulating valve, disposed in front of the opening of a duct.

Ces clapets s'utilisent avantageusement pour le réglage de l'admission d'air de brûleurs de chaudières et de chauffe-eau à gaz pour assurer un dosage d'air frais en fonction du débit de combustible donné. These valves are advantageously used for adjusting the air intake of boiler burners and gas water heaters to ensure a metering of fresh air as a function of the given fuel flow rate.

L'invention a pour but de réaliser un tel clapet- de sorte que la position du clapet à l'intérieur de la plage maxi de pivotement soit aussi exactement que possible linéairement proportionnelle au débit d'air frais. The object of the invention is to produce such a valve so that the position of the valve within the maximum pivot range is as exactly as possible linearly proportional to the flow of fresh air.

Conformément à l'invention, le clapet est articulé, à cette fin, autour d'un axe disposé dans le plan de 1' ouverture du conduit et en dehors de celui-ci, et est en contact étanche, par une partie cylindrique, avec la face extérieure d'un bord droit tangentiel du conduit. According to the invention, the valve is articulated, for this purpose, about an axis disposed in the plane of the opening of the duct and outside of it, and is in sealed contact, by a cylindrical part, with the outer face of a tangential straight edge of the conduit.

Grâce à cette disposition, l'ouverture du conduit, dégagée par le clapet par rapport à la section totale d'écoulement correspondra assez exactement, en proportion linéaire, à l'angle de pivotement du clapet. Le réglage du volume d'air frais peut donc se faire en fonction directe de celui du volume de combustible, ce qui se traduit par une forte simplification. Thanks to this arrangement, the opening of the duct, released by the valve relative to the total flow section will correspond fairly exactly, in linear proportion, to the pivot angle of the valve. The adjustment of the volume of fresh air can therefore be done as a direct function of that of the volume of fuel, which results in a great simplification.

Compte tenu de la forme préférée de l'objet de 1' invention, l'angle de pivotement maximum du clapet est d'environ 450 qui correspond à un débit de 100% à travers la section d'écoulement donnée. Given the preferred form of the object of one invention, the maximum pivot angle of the valve is about 450 which corresponds to a flow rate of 100% through the given flow section.

Il se montre en outre avantageux de prévoir sur le clapet un rebord regardant l'ouverture du conduit et délimitant un creux, conception favorisant un écoulement sans frottement le l-ong du plan du clapet dans la zone de déviation entre l'axe du conduit et l'axe du courant dévié par le clapet. La hauteur de ce rebord devrait correspondre, comme l'expérience le montre, à environ un huitième de la largeur d'ouverture maximale, donc à un arc représentant environ un huitième de l'angle d'ouverture maximum.  It also proves to be advantageous to provide a flange on the valve looking at the opening of the conduit and delimiting a hollow, design promoting a flow without friction the l-ong of the plane of the valve in the deviation zone between the axis of the conduit and the axis of the current deflected by the valve. The height of this rim should correspond, as experience shows, to approximately one eighth of the maximum opening width, therefore to an arc representing approximately one eighth of the maximum opening angle.

De plus, il est avantageux de disposer l'axe à une distance vis-à-vis du conduit, correspondant à environ un quart de son diamètre intérieur mesuré en direction de ladite distance. In addition, it is advantageous to have the axis at a distance from the conduit, corresponding to approximately a quarter of its internal diameter measured in the direction of said distance.

Un exemple de réalisation de l'invention est décrit avec la seule figure du dessin à l'appui, qui montre une coupe schématique du clapet:
Le clapet lui-même est désigné par 1, comprenant une partie 2 cylindrique, une partie plane 3 et un rebord 4 qui, avec la partie 3, délimite un creux 5 plan, orienté vers l'ouverture du conduit.An exemplary embodiment of the invention is described with the single figure of the drawing in support, which shows a schematic section of the valve:
The valve itself is designated by 1, comprising a cylindrical part 2, a flat part 3 and a flange 4 which, with part 3, delimits a flat recess 5, oriented towards the opening of the duct.

Le clapet 1 peut pivoter autour de l'axe 6, la partie cylindrique 2 se déplaçant suivant un arc 7. Le conduit 8 est délimité par la paroi 9, droite au niveau du bord 10 et tangentant ainsi la partie 2 comme une génératrice. The valve 1 can pivot around the axis 6, the cylindrical part 2 moving in an arc 7. The duct 8 is delimited by the wall 9, straight at the edge 10 and thus tangent the part 2 as a generator.

Les cotes- données dans le dessin montrent que, du fait de cette disposition, à chacune des positions angulaires indiquées du clapet entre 0 et à peu près 450 correspondent en proportion linéaire une section entre 0 et 100% de l'ouverture maximale et le débit. The dimensions given in the drawing show that, because of this arrangement, to each of the indicated angular positions of the valve between 0 and approximately 450 correspond in linear proportion a section between 0 and 100% of the maximum opening and the flow .

Du dessin ressortent aussi la distance optimale de l'axe de pivotement 6 vis-à-vis du bord 10, et la hauteur du rebord 4. The drawing also shows the optimal distance from the pivot axis 6 with respect to the edge 10, and the height of the flange 4.

Les valeurs inscrites au niveau de l'ouverture du conduit 8 représentent le débit en pourcentage en fonction des différentes positions du clapet 1. Les chiffres à la périphérie indiquent les différents angles d'ouverture du clapet jusqu'à la valeur maximale d'environ 450, en huit paliers, y compris les angles et arcs correspondants.  The values entered at the opening of the duct 8 represent the flow in percentage as a function of the different positions of the valve 1. The figures on the periphery indicate the different angles of opening of the valve up to the maximum value of approximately 450 , in eight steps, including the corresponding angles and arcs.
