Abstract
Description
l .a demande de brevet qui suit a pour objet une Electrovanne de Sécurité d'Alimentation Gaz à Itéarrnement Manuel qui répond en particulier à l'arrêté du 10 août. 1998 modifiant l'annexe 1 de l'arrêté du 25 juillet 1997 relatif aux prescriptions générales applicables aux installations classées pour la protection<B>de</B> l'environnement soumises à déclaration sous la rubrique n <B>2910</B> (C'.ombustion) ainsi qu'à tout autre norme prévoyant l'emploi d'un tel dispositif Cette électrovanne est utilisée en amont des lignes d'alimentation en gaz des installations industrielles et a pour fonction d'interrompre l'alimentation du gaz lorsque l'on coupe la tension électrique à ses bornes. II s'agit donc d'une vanne dite normalement fermée . Cette coupure de tension peut être provoquée par un pressostat, un détecteur de gaz, un arrêt coup<B>de</B> poing ou tout autre dispositif choisi par l'utilisateur. The following patent application relates to a manual feed gas safety solenoid valve which responds in particular to the decree of 10 August. 1998 amending Annex 1 of the Order of 25 July 1997 on general requirements for installations classified for the protection of the environment <B> of </ B> subject to declaration under heading n <B> 2910 </ B > (Combustion) as well as any other standard providing for the use of such a device This solenoid valve is used upstream of the gas supply lines of industrial installations and has the function of interrupting the power supply to the plant. gas when the electrical voltage is cut at its terminals. It is therefore a so-called normally closed valve. This voltage failure can be caused by a pressure switch, a gas detector, a fist strike or any other device chosen by the user.
Il est très important de noter que la norme â laquelle nous faisons référence prévoit que l'état de la vanne (ouverte ou fermée) doit être clairement visible. La particularité de cette invention est justement que, bien que la position<B>de</B> son levier indique clairement l'état de la vanne, il n'est pas possible de la maintenir intentionnellement ouverte en absence de courant en agissant sur ledit levier, faute de quoi cet appareil ne pourrait être considéré comme un organe de sécurité. 1)e plus cette indication visucllc n'est pas dépcndantc du système électrique ce qui supprime tous les doutes inhérents à cette technologie. (Voyant lumineux défectueux, faux contact, etc.) Principe de fonctionnement l ,e principe de base de cette électrovanne qui fait l'objet<B>de</B> la présente demande <B>de</B> protection d'invention est l'utilisation de<B>deux</B> ventouses électromagnétiques à manque de tension pour maintenir le clapet en position ouvert. C'.es ventouses qui sont depuis longtemps utilisées dans l'équipement automobile et ferroviaire principalement, présentent la pî,irticularitE d'offrir une très grande force de maintien pour une consommation électrique très faible. It is very important to note that the standard to which we refer provides that the condition of the valve (open or closed) must be clearly visible. The peculiarity of this invention is precisely that, although the position <B> of </ B> its lever clearly indicates the state of the valve, it is not possible to keep it intentionally open in the absence of current by acting on said lever, otherwise this device could not be considered as a safety organ. 1) the more this visual indication is not depcndantc the electrical system which removes all the doubts inherent in this technology. (Faulty indicator light, false contact, etc.) Operating Principle The basic principle of this solenoid valve which is the object of this protection application is The invention is the use of <B> two </ B> vacuum electromagnetic vacuum clamps to hold the valve in the open position. These suction cups, which have been used for a long time in automotive and railway equipment, have the advantage of offering a very high holding power for a very low power consumption.
Dans le cas présent, le système se compose d'une ventouse mobile (1) qui est solidaire, en présence<B>de</B> la. tension électrique, d'une part à une ventouse fixe (2) et à un plateau lié au clapet d'autre part (Schéma 1). l'a ventouse mobile est actionnée par un levier (4) qui fait aussi office d'indicateur d'état<B>de</B> la vanne. Grâce à ce système de double ventouse la vanne ne petit être maintenue en position ouverte <B>en</B> absence de courant. Mode de réalisation Ces électrovannes de sécurité à réarmement manuel peuvent être fabriquées dans les versions suivantes : Pression max. : Jusqu'à 16bars suivant les versions. In this case, the system consists of a movable suction cup (1) which is secured in the presence of <B> of </ b> la. electrical voltage, on the one hand to a fixed suction cup (2) and a plate connected to the valve on the other hand (Diagram 1). the movable suction cup is actuated by a lever (4) which also serves as a status indicator <B> of the valve. Thanks to this system of double sucker the valve can not be kept in open position <B> in </ B> absence of current. Embodiment These manual reset solenoid valves can be manufactured in the following versions: Max. : Up to 16bars depending on the versions.
Diamètres : DN 50, DN 80, DN 100, UN 125, l)N 150, DN200 Tensions d'alimentation : 230 VAC'., 24 VDC, 48VDC'. Consommation : de 5 watts pour la 1D50 à 20 watts pour la DN200. F.llcs seront équipées, pour la gestion interne du fonctionnement, d'un pressostat de contrôle de fa pression aval, de deux contacts inverseurs pour la position ouverte et fermée et d'un système de by-pass automatique pour l'équilibrage progressif des pressions amont et aval avant la réouverture, <B>Le</B> Schéma 2 nnontrc le principe du by-pass. Diameters: DN 50, DN 80, DN 100, UN 125, l) N 150, DN200 Supply voltages: 230 VAC '., 24 VDC, 48VDC'. Consumption: from 5 watts for the 1D50 to 20 watts for the DN200. F.llcs will be equipped, for the internal management of the operation, with a downstream pressure control switch, two inverter contacts for the open and closed position and an automatic bypass system for the progressive balancing of Upstream and downstream pressures before reopening, <B> The </ B> Diagram 2 doesncontrol the bypass principle.
Le pressostat assure la coupure de la tension (donc la fermeture de la vanne) dés que la pression aval chute sous un seuil prédéterminé. The pressure switch ensures the cutoff of the voltage (thus closing the valve) as soon as the downstream pressure drops below a predetermined threshold.
Pour la réouverture manuelle de 1a vanne, le contact position fermée permettra l'excitation de la bobine (1) (Schéma l), môme en absence de pression suffisante en aval c. à d sans autorisation du pressostat, ce qui permettra de la solidariser de l'axe du clapet (3) et de commencer à soulever ce dernier en actionnant. le by-pass jusqu'à l'équilibrage des pressions. A ce mottient le pressostat autorisera l'alimentation des bobines (1) et (2) et donc l'arrimage de l'équipage formé par la bobine (1) et l'axe du clapet (3) sur la bobine (2). For the manual reopening of the valve, the closed position contact will allow excitation of the coil (1) (Scheme 1), even in the absence of sufficient pressure downstream c. to d without authorization of the pressure switch, which will make it possible to secure it to the axis of the valve (3) and to start to lift the latter by actuating. the bypass until balancing pressures. At this mottient the pressure switch will allow the supply of the coils (1) and (2) and thus the stowage of the crew formed by the coil (1) and the axis of the valve (3) on the coil (2).
En option, l'état des contacts du pressostat et des fins de course pourra être reporté sur un bornier de sortie. Optionally, the state of the pressure switch contacts and limit switches can be transferred to an output terminal block.
