Description
DISPOSITIF ELECTROMAGNETIQUE POUR LA REGULATION ET LA MODULATION DE LAELECTROMAGNETIC DEVICE FOR REGULATING AND MODULATING THE
PRESSION DU GAZ DANS DES CHAUDIERES MURALES. GAS PRESSURE IN WALL BOILERS.
La présente invention concerne un dispositif électromagnétique d'une grande simplicité de structure et, par conséquent, très bon marché 5 et très facile à entretenir, qui permet d'effectuer à la fois une régulation et une modulation au moyen des mêmes éléments, avec une grande linéarité et, par conséquent, une bonne fiabilité ainsi qu'une grande rapidité de réponse aux commandes de régulation du débit de gaz combustibles, tels que le méthane ou analogue, dans des matériels de petite et de moyenne capacité thermique, t e-ls que les chaudières murales, les générateurs de chaleur, etc. On connaît, dans la technique antérieure, de nombreux types de ces dispositifs, mais tous les dispositifs connus actuellement vendus sur le marché sont compliqués, encombrants et coûteux et sont constitués 15 par de nombreuses pièces qu'il faut assembler et qui, par conséquent, compliquent leur entretien; en outre, on obtient la régulation de la pression du gaz à l'aide de moyens différents de ceux utilisés pour la modulation de cette même pression du gaz avec, pour conséquence, The present invention relates to an electromagnetic device of great structural simplicity and therefore very inexpensive and very easy to maintain, which makes it possible to carry out both regulation and modulation by means of the same elements, with a high linearity and, therefore, good reliability and rapid response to commands for regulating the flow of combustible gases, such as methane or the like, in materials of small and medium thermal capacity, t e-ls than wall-mounted boilers, heat generators, etc. Numerous types of these devices are known in the prior art, but all of the known devices currently sold on the market are complicated, bulky and expensive and consist of numerous parts which have to be assembled and which consequently complicate their maintenance; moreover, gas pressure is obtained by means of means different from those used for the modulation of this same gas pressure with, consequently,
d'autres complications.other complications.

En outre, les trous calibrés et les passages de petit diamètre qui y sont adoptés sont facilement sujets à être souillés, ce qui les rend moins fiables et, de plus, présentent des valeurs élevées de frottement et d'hysteresis qui ne permettent pas d'obtenir une linéarité ou une réponse rapide. Le but de la présente invention est, précisément, de remédier aux inconvénients mentionnés ci-dessus et de fournir, par conséquent, un dispositif de régulation et de modulation de pression de gaz qui est In addition, the calibrated holes and the small-diameter passages which are adopted therein are easily subject to being soiled, which makes them less reliable and, moreover, have high values of friction and hysteresis which do not allow get linearity or quick response. The object of the present invention is, precisely, to remedy the drawbacks mentioned above and to therefore provide a device for regulating and modulating gas pressure which is
extrêmement fiable, simple et non encombrant et qui, par conséquent, 10 est bon marché et donne des résultats extrêmement précis que l'on obtient sans opération d'usinage précise de sorte qu'on peut le fabriquer en aluminium moulé. extremely reliable, simple and space-saving and which, therefore, is inexpensive and gives extremely precise results which are obtained without precise machining operation so that it can be made from cast aluminum.
On obtient ce résultat essentiellement en tirant parti d'un principe qui n'a jamais été utilisé dans ce domaine, à savoir le réglage de la pression de sortie du gaz (le point de réglage),au moyen d'une bobine mobile et d'un aimant fixe qui ont permis à la demanderesse de combiner les fonctions d'un régulateur et d'une valve de modulation de pression. En d'autres termes, on effectue une régulation et une This is mainly achieved by taking advantage of a principle that has never been used in this area, namely the adjustment of the gas outlet pressure (the set point), by means of a voice coil and d '' a fixed magnet which have enabled the applicant to combine the functions of a regulator and a pressure modulation valve. In other words, regulation and
modulation de la pression de sortie du gaz en fonction du courant élec20 trique circulant à travers la bobine mobile. modulation of the gas outlet pressure as a function of the electric current flowing through the voice coil.
Plus spécifiquement, le dispositif électromagnétique pour la régulation et la modulation du gaz dans des chaudières murales comprenant un obturateur faisant corps avec la membrane du régulateur est caractérisé selon la présente invention par le fait qu'avec cette membrane est éga25 lement solidaire une bobine pouvant se déplacer à l'intérieur d'un aimant fixe. On obtient, en fait, les très bonnes caractéristiques de ce dispositif électromagnétique en exploitant la force de répulsion qui est créée entre la bobine mobile et l'aimant et qui est directement propor30 tionnelle au courant circulant à travers cette bobine de sorte que la force qui s'exerce aussi sur la membrane et, par conséquent, sur l'obturateur et qui détermine la valeur de la pression du gaz est directement More specifically, the electromagnetic device for regulating and modulating gas in wall-mounted boilers comprising a shutter integral with the membrane of the regulator is characterized according to the present invention by the fact that with this membrane is also integral a coil which can be move inside a fixed magnet. We obtain, in fact, the very good characteristics of this electromagnetic device by exploiting the repulsion force which is created between the moving coil and the magnet and which is directly proportional to the current flowing through this coil so that the force which also acts on the diaphragm and, therefore, on the shutter and which determines the value of the gas pressure is directly
proportionnelle au courant circulant à travers la bobine. proportional to the current flowing through the coil.
On va maintenant expliquer de façon plus complète la présente in35 vention en se référant aux dessins annexés qui représentent, à titre purement illustratif et non limitatif, un mode de réalisation pratique préféré de la présente invention et sur lesquels: La figure 1 est une vue en perspective partiellement écorchée du régulateur électromagnétique de pression selon l'invention incor5 poré dans un dispositif de régulation de pression du gaz avec l'électrovalve de-sécurité et la valve marche- arrêt; La figure 2 est une vue en coupe longitudinale, à une échelle The present invention will now be explained in more detail with reference to the accompanying drawings which represent, by way of illustration only and not limitation, a preferred practical embodiment of the present invention and in which: FIG. 1 is a view in partially cutaway perspective of the electromagnetic pressure regulator according to the invention incorporated in a device for regulating the gas pressure with the solenoid safety valve and the on-off valve; Figure 2 is a longitudinal sectional view, to a scale

La sortie 7 du dispositif de régulation de pression de gaz est ensuite commandé par la valve marche-arrêt 8 qui-commande l'écoulement The outlet 7 of the gas pressure regulating device is then controlled by the on-off valve 8 which controls the flow
du gaz depuis le conduit 9 jusqu'à l'orifice de sortie 7. gas from line 9 to outlet 7.
Enfin, l'écoulement du gaz depuis le conduit 6 jusqu'au conduit 9 est commandé par le dispositif électromagnétique 10 de régulation 20 modulation selon la présente invention, qui comprend un obturateur 11 faisant corps avec une membrane 12 maintenue dans sa position au moyen du corps 13 fixé à l'ensemble monobloc 4 au moyen des vis 14. Sur cette membrane 12 est aussi fixée une bobine mobile 15 qui peut coulisser Finally, the flow of gas from line 6 to line 9 is controlled by the electromagnetic device 10 for regulating modulation 20 according to the present invention, which comprises a shutter 11 integral with a membrane 12 held in its position by means of the body 13 fixed to the monobloc assembly 4 by means of screws 14.
