Abstract

The sprinkler is constituted from a casing comprising three parts, a cylindrical body (1) and two domed ends (2). One dome has an orifice (3) with an external chamfered bell mouth (6) forming a liquid corolla outlet. The sprinkler is located vertically with the orifice directed upwards and is held there by the liquid supply tube (4). The liquid supply tube (4) has a threaded connector (5) and a chamfered side section. The tube is fixed opposite a radial opening (7) of corresponding shape in the cylindrical body. Entry of the liquid from the tube is tangential to the internal wall of the cylindrical body and thereby creates a centrifugal movement of the liquid before it is sprayed out in a corolla.

Description

DESCRIPTION
La présente invention conceme un dispositif de pulvérisation de liquide permettant entre autres de lutter contre l'incendie dû à des excès de paraffine, par exemple à l'intérieur d'une gaine d'extraction située sur une machine textile, ou contre un incendie de cheminée (inserts par exemple).DESCRIPTION
The present invention relates to a liquid spraying device making it possible inter alia to fight against fire due to excess paraffin, for example inside an extraction sheath located on a textile machine, or against a fire of fireplace (inserts for example).

Ceb peut concemer aussi les séchoirs, rames textiles, fours, chaudières.Ceb can also be used for dryers, reams, ovens, boilers.

Actuellement, les divers systèmes existants pour lutter contre les incendies sur machines textiles utilisent des jets de vapeur qui ont pour but d'étouffer les flammes mais ont l'inconvénient de surchauffer les gaines, de réchauffer la paraffine avec souvent pour conséquence de relancer l'rincez die dès l'arrêt des jets de vapeur.Currently, the various existing systems for fighting fires on textile machines use steam jets which aim to smother the flames but have the disadvantage of overheating the sheaths, of heating the paraffin, often with the consequence of relaunching the rinse die as soon as the steam jets stop.

Le dispositif selon l'invention permet de remédier à cet inconvénient car l'eau pulvérisée refroidit les gaines.The device according to the invention overcomes this drawback because the sprayed water cools the sheaths.

Ce dispositif comporte en effet un boîtier cylindrique en métal tel qu'acier inoxydable ou aluminium, dont l'axe est disposé verticalement, ne comportant aucun mécanisme intérieur, où sont assemblés aux extrémités deux fonds bombés de même diamètre, I'un de ces fonds est percé d'un trou fraisé d'un diamètre idéal de 4 mm + 2 mm - 0,5 mm disposé selon l'axe sur la partie supérieure du boitier.This device indeed comprises a cylindrical metal case such as stainless steel or aluminum, the axis of which is arranged vertically, having no internal mechanism, where two rounded ends of the same diameter are assembled at the ends, one of these ends is drilled with a milled hole with an ideal diameter of 4 mm + 2 mm - 0.5 mm placed along the axis on the upper part of the case.

L'arrivée d'eau ou de tout autre liquide est réalisée à l'aide d'un tube qui sera d'un côté coupé en biseau et de l'autre côté possédera un raccord standard pour l'alimentation.The inlet of water or any other liquid is carried out using a tube which will be cut on one side and on the other side will have a standard connection for the supply.

Le côté biseauté sera raccordé sur la partie cylindrique du boîtier de telle façon que l'eau arrive tangeantiellement sur la paroi interne de celui-ci, cette eau arrivant dans le boîtier à la pression du réseau, le remplit en même temps qu'elle exerce une force centrifuge à l'intérieur de celui-ci. Lorsque le boiter est plein, il est mis en pression et l'eau débouchant en partie supérieure est pulvérisée en corolle à l'extérieur par le trou fraisé. Proportionnellement à la grosseur du troubla pulvérisation sera plus ou moins importante.The bevelled side will be connected to the cylindrical part of the housing in such a way that the water arrives tangentially on the internal wall of the latter, this water arriving in the housing at the pressure of the network, fills it at the same time as it exerts a centrifugal force inside of it. When the box is full, it is put under pressure and the water emerging in the upper part is sprayed in a corolla outside through the milled hole. In proportion to the size of the spray troubla will be more or less important.

II résulte de ce mode de fonctionnement que le dispositif peut être orientable avec son orifice dirigé vers le haut, le bas ou le côté. It follows from this operating mode that the device can be orientable with its orifice directed upwards, downwards or to the side.

Selon une variante non illustrée, le boîtier pourrait être conçu dans n'importe quelle autre matière, notamment matière plastique, équipé sur sa partie inférieure d'un support permettant une utilisa tion dans des domaines comme l'arrosage de jardins, cultures, et autres plantations, ceci avec une très faible consommation d'eau et peu de pression.According to a variant not illustrated, the box could be designed in any other material, in particular plastic, equipped on its lower part with a support allowing use in fields such as watering gardens, crops, and other plantations, this with very low water consumption and little pressure.

A titre indicatif, I'appareil peut être enterré et grâce à son orifice, cet appareil se met hors gel en hiver.As an indication, the device can be buried and thanks to its orifice, this device freezes in winter.

A titre d'exemple non limitatif, le boîtier peut être constitué d'un tube de 60 mm de long, de diamètre 50 mm intérieur et de diamètre 60 mm extérieur.By way of nonlimiting example, the box can consist of a tube 60 mm long, with an inside diameter of 50 mm and an outside diameter of 60 mm.

A titre d'exemple, des dessins sont faits qui représentent: - Fig. 1, une vue de face du dispositif.By way of example, drawings are made which represent: - Fig. 1, a front view of the device.

- Fig. 2, une vue de dessus.- Fig. 2, a top view.

- Fig. 3, une vue de côté avec arraché. - Fig. 3, a side view with snatch.

En référence à ces dessins;
L'invention concerne un dispositif permettant d'éteindre les incendies qui se déclenchent à l'inté- rieur d'une gaine d'extraction, et peut également servir de système d'arrosage.With reference to these drawings;
The invention relates to a device for extinguishing fires which start inside an extraction duct, and can also be used as a sprinkler system.

II est constitué d'un boîtier comprenant trois parties, dont un corps cylindrique (1) et de deux fonds bombés (2) dont l'un est percé d'un orifice (3) pourvu d'un évasement extérieur (6) tel qu'un chanfrein conique obtenu par fraisage permettant de définir selon son ouverture l'angle de sortie en corolle du liquide. L'arrivée de liquide est réalisée à l'aide d'un tube (4) qui a un côté coupé en biseau orienté et fixé en vis à vis d'une ouverture radiale (7) de forme correspondante réalisée sur le corps cylindrique (1) afin de définir une arrivée de liquide tangentielle à la paroi intérieure du corps cylindrique (1). L'ouverture (7) est située dans l'exemple illustré de façon non limitative en partie centrale. Le tube (4) possède un raccord (5) notamment un filetage pour son raccordement à un tuyau d'alimentation par lequel le liquide arrive sous pression, de sorte à exercer sur ce liquide, remplissant le boîtier, un mouvement centrifuge permettant une pulvérisation de celui-ci en corolle à l'extérieur du boîtier par l'orifice (3). It consists of a housing comprising three parts, including a cylindrical body (1) and two curved bottoms (2), one of which is pierced with an orifice (3) provided with an external flare (6) such that '' a conical chamfer obtained by milling allowing to define according to its opening the exit angle in corolla of the liquid. The liquid inlet is made using a tube (4) which has a side cut in an oriented bevel and fixed opposite a radial opening (7) of corresponding shape made on the cylindrical body (1 ) to define a liquid inlet tangential to the inner wall of the cylindrical body (1). The opening (7) is located in the example illustrated without limitation in the central part. The tube (4) has a connector (5) in particular a thread for its connection to a supply pipe through which the liquid arrives under pressure, so as to exert on this liquid, filling the housing, a centrifugal movement allowing a spraying of this corolla outside the housing through the orifice (3).

Dans son application à la lutte contre l'incendie dans des gaines ou des cheminées (8), le dispositif est installé verticalement par exemple, axialement à l'intérieur du conduit, à mi-hauteur, du fait que le jet en corolle (9) produit à la sortie du trou (3) orienté vers le haut s'élève sur une hauteur d'environ 2 mètres, tout en couvrant une surface pouvant atteindre 1 mètre carré, en arro- sant les parois, les refroidissant et retombant en fines gouttelettes, ceci sous une pression d'alimentation d'environ deux bars. Cette disposition ne gène pas le passage des fumées et la pose se ré alise aisément par une simple découpe dans la paroi pour le passage du tube (4) qui assure le maintien en position grâce au filetage (5) de façon préférentielle et simplifiée In its application to fire fighting in ducts or chimneys (8), the device is installed vertically, for example, axially inside the duct, halfway up, because the corolla jet (9 ) produced at the exit of the upward-facing hole (3) rises to a height of about 2 meters, while covering an area of up to 1 square meter, watering the walls, cooling them and falling down into fines droplets, this under a supply pressure of about two bars. This arrangement does not interfere with the passage of smoke and the installation is easily carried out by a simple cut in the wall for the passage of the tube (4) which ensures the maintenance in position thanks to the thread (5) in a preferential and simplified manner
