  • the pressure level is not a constant value and depends on many factors, including the room temperature.

  • the location of the inlet sections of the outlets from the side of the upper end of the fitting, and the L-shaped channels - in the wall of the fitting (outside the drain neck) reduces the hydraulic resistance when the fire extinguishing agent flows out of the housing and increases the speed of the module.
  • Installation of copper siphon tubes in the inlet sections of the outlets by means of a threaded connection diametrically opposite i.e. at the maximum distance from each other greatly simplifies the installation of the tubes themselves, as well as access to the safety valve and pressure sensor when performing inspections and recharging the module.
  • the implementation of the height of the siphon tubes in the range of 0.9 ⁇ 0.95 of the inner diameter of the body is guaranteed to ensure that the upper end sections of the siphon tubes are always located in the gas zone, which prevents the liquid freon from entering the safety valve and pressure sensor when the module is tilted or moved

Abstract

L'invention se rapporte aux dispositifs anti-incendie pour extinction volumétrique qui utilisent des substances d'extinction de feu liquides. Ce module d'extinction d'incendie comprend un corps rempli d'une substance d'extinction de feu se trouvant à une pression excédentaire avec une unité de fixation dans la partie supérieure, un dispositif d'alimentation-éjection situé dans la partie inférieure du corps et se présentant sous forme d'un raccord orienté verticalement avec des sorties pour un clapet de sécurité et un capteur de la pression dans le corps. Le module comprend deux tubes de siphon disposés verticalement dans le corps; ce dernier possède une forme sphérique. La substance d'extinction de feu est contenue dans le corps à l'état liquide de manière à former au-dessus de celui-ci une zone gazeuse. Chaque sortie se présente sous forme d'un clapet dans la paroi du raccord dont la section d'entrée se situe du côté de l'extrémité supérieure du raccord. Dans la section d'entrée de chaque capteur se trouve un tube de siphon, et les sections d'extrémité supérieures des tubes de siphon se situent dans la zone gazeuse. Il est ainsi possible d'utiliser dans le module d'extinction d'incendie diverses substances d'extinction de feu, y compris un gaz liquéfié et un liquide; le module d'extinction d'incendie est outre caractérisé par une relation optimale de la masse du réservoir et de la substance d'extinction de feu qu'il contient.
