DESOUFflON
La présente invention concerne les dispositifs permettant aux installations de protection incendie, système extinction automatique par eau, pour fonctionner en méthode sous vide en lieu et place des réseaux sous pressions appliquées à ce jour.DESOUFflON
The present invention relates to devices enabling fire protection installations, automatic water extinguishing system, to operate in a vacuum method in place of the pressure networks applied to date.
Le nouveau système (Fig. 1)inventé est basé essentiellement sur la technique "par le vide" obtenue par la mise en place "caractérisée par" les composants suivants : l'obturateur (5 - Fig. 1) et la pompe à vide (6 - Fig. 1). Avec ces ensembles figurent l'adjonction au pulvérisateur: d'une collerette (7 - Fig. 3) et d'un ressort d'éjection (6 - Fig. 3). Les installations peuvent fonctionner sous-vide, c'est-à-dire la suppression totale de l'air comprimé. The new system (Fig. 1) invented is based essentially on the "vacuum" technique obtained by the installation "characterized by" the following components: the shutter (5 - Fig. 1) and the vacuum pump ( 6 - Fig. 1). These sets include the addition to the sprayer: of a flange (7 - Fig. 3) and an ejection spring (6 - Fig. 3). The systems can operate under vacuum, i.e. the total removal of compressed air.
Pour la mise en service, la procédure est la suivante: fermeture de la vanne (1 - Fig. 1), mettre en marche la pompe à vide (6 - Fig. 1), appliquer l'ogive d'obturation (2 - Fig. 2) contre l'orifice de mise à vide (16 - Fig. 2). Pour permettre cette manoeuvre, pousser la poignée (5 - Fig. 2) jusqu'à buter l'ogive dans le canal orifice de mise à vide (16 - Fig. 2). La pompe à vide (6 - Fig.1) retiendra par son aspiration
l'ogive d'obturation. Relâcher la poignée, ouvrir la vanne (11 - Fig. 1) pour mise à pression de la chambre de la soupape (2 - Fig. 1). Les équilibrage et fermeture de la chambre se feront par l'intermédiaire du PORV (4 - Fig. 1) et du restricteur (3 - Fig.For commissioning, the procedure is as follows: closing the valve (1 - Fig. 1), switching on the vacuum pump (6 - Fig. 1), applying the sealing wedge (2 - Fig. 2) against the vacuum opening (16 - Fig. 2). To allow this maneuver, push the handle (5 - Fig. 2) until the warhead abuts in the vacuum orifice channel (16 - Fig. 2). The vacuum pump (6 - Fig. 1) will retain by its suction
the shutter warhead. Release the handle, open the valve (11 - Fig. 1) to pressurize the valve chamber (2 - Fig. 1). Balancing and closing of the chamber will be done through the PORV (4 - Fig. 1) and the restrictor (3 - Fig.
1). Lorsque les 2 pressions sont identiques et visibles sur les manomètres à cadrans (19 - 20 - Fig. 1), pression amont et pression aval, la chambre supérieure (2 - Fig. 1) est ainsi opérationnelle. Ensuite, ouvrir la vanne (1 - Fig. 1) pour mise en service de l'installation. Les réseaux sous vide seront maintenus en service à une pression de (moins) 0,6 bar environ.1). When the 2 pressures are identical and visible on the dial gauges (19 - 20 - Fig. 1), upstream pressure and downstream pressure, the upper chamber (2 - Fig. 1) is thus operational. Then open the valve (1 - Fig. 1) to commission the installation. The vacuum systems will be kept in service at a pressure of (minus) 0.6 bar.
Les protections incendie par sprinkleurs installées dans des zones non chauffées et risquant le gel, sont généralement prévues et maintenues sous air ou sous eau glycolée, l'ensemble étant sous pression. Ces types d'installations présentent beaucoup d'inconvénients, à savoir: - Temps d'arrivée d'eau trop lent. Fire protection by sprinklers installed in unheated areas and risk of frost, are generally provided and maintained in air or in brine, the whole being under pressure. These types of installations have many disadvantages, namely: - Water intake time too slow.
- Un entretien et une surveillance quasi-permanents.- Quasi-permanent maintenance and monitoring.
- Une accumulation de condensation qui gèle aux points bas et qui provoque des
bouchons de glace, d'où le risque de dégâts sur les réseaux, ou risque de
neutralisation de la protection durant un certain temps si un tampon de glace se
si tue dans les canalisations principales, dû à une contre-pente. - An accumulation of condensation which freezes at low points and which causes
ice plugs, hence the risk of damage to the networks, or risk of
protection deactivation for a certain time if an ice pad is
if kills in the main pipes, due to a counter-slope.
- Les installations présentent une corrosion plus rapide au niveau des tuyauteries.- The installations exhibit faster corrosion in the pipes.
- Surface et nombre de sprinkleurs limités par poste.- Area and number of sprinklers limited per station.
- Additif glycol, nécessitant des brassages des installations avec recyclages fréquents.- Glycol additive, requiring mixing of the installations with frequent recycling.
- Utilisation de matériel de qualité supérieure.- Use of high quality material.
- Installations et exploitation beaucoup plus onéreuses.- Much more expensive installations and operation.
Les avantages d'une installation sous vide: - Temps d'arrivée d'eau très court - Un entretien et une surveillance réduits.The advantages of a vacuum installation: - Very short water arrival time - Reduced maintenance and monitoring.
- Aucune condensation.- No condensation.
- Aucune corrosion.- No corrosion.
- Surface plus importante assurée par un poste sous vide.- Larger surface provided by a vacuum station.
- Suppression totale du glycol.- Total removal of glycol.
- Utilisation de matériel standard et classique.- Use of standard and classic equipment.
- Installations moins onéreuses.- Less expensive installations.
- Longévité des installations.- Longevity of installations.
- Suppression de la contrainte de chauffer des bâtiments pour maintenir des
réseaux sous eau.- Removal of the constraint of heating buildings to maintain
underwater networks.
- Suppression des contraintes des rinçages des installations pendant l'exploitation.- Removal of the constraints of rinsing the installations during operation.
- Minimiser considérablement les coûts et temps de l'exploitation et l'entretien. - Significantly minimize the costs and time of operation and maintenance.
- Permet l'installations dans des zones ou secteurs extrêmement froids.- Allows installation in extremely cold areas or sectors.
- Une surveillance et un entretien moins contraignants.- Less restrictive monitoring and maintenance.
- Une remise en service rapide et facile sans changement fréquent de pièces.- Quick and easy return to service without frequent change of parts.
- Pièces de rechange très limitées.- Very limited spare parts.
- Une grande fiabilité quant à l'exploitation.- High operational reliability.
