Definitions

  • the invention relates to a fire protection system with glass barrel sensors, for example for sprinkler systems that release the extinguishing agent outlet openings of the system in the event of a fire.
  • Extinguishing agent can escape immediately or, in the case of dry extinguishing systems, reaches the extinguishing agent outlet opening. With the resulting pressure drop in the system, the system is controlled and the pumps start to provide the extinguishing agent.
  • the key criteria for the effectiveness and reliability of such systems are the trigger temperature and the response speed of the glass barrel sensors.
  • the vapor pressure of the liquid enclosed in the glass barrel or the size of the bubble determines the level of the trigger temperature, the size of the diameter of the glass barrel determines the response speed. In a number of practical cases, however, it has been shown that the responsiveness of the
  • the problem of the invention thus consists in the creation of an inexpensive fire protection system which has the high standard in terms of safety and reliability of high-performance extinguishing systems controlled by fire alarm systems, but does not require their high expenditure.
  • rapid detection and localization of the fire as well as the immediate opening of the extinguishing agent outlet openings required to contain or liquidate the fire should be possible without significantly increasing the effort and while maintaining the principle of the release of the extinguishing agent by glass barrel sensors.
  • the maintenance effort should be similar to that of sprinkler systems.
  • a heating element for example, can be provided on or in the glass barrel, which heats up the liquid contained therein. Resistance heating wires are just as suitable for this
  • Thermocouples With both variants it is also possible to monitor the temperature of the liquid.
  • the glass barrel and sensor element can be connected in different ways.
  • a heating element is mechanically clamped on the outside of the glass barrel. It is also possible to glue sensor elements to the wall using a heat-resistant adhesive. If the heating element is integrated into the wall of the glass barrel during production or is passed through its interior, these glass barrel sensors have a high sensitivity and response speed.
  • the mechanically movable plungers of the already known electrically triggerable sprinklers are controlled so that they are also suitable for scanning the glass barrel.
  • these sprinklers require an additional temperature monitoring sensor.
  • FIG. 2 shows the sectional view through the glass barrel sensor.
  • FIG. 3 a glass barrel sensor with a thermocouple located in the liquid
  • 4 shows a glass barrel sensor with a heating spiral located in the liquid
  • FIG. 5 shows the sectional view through the glass barrel sensor according to FIG. 4
  • FIG. 6 a glass barrel sensor with a thermocouple integrated in the wall of the glass tube in a sectional view
  • FIG. 7 a glass barrel sensor with a resistance heating wire integrated in the wall of the glass tube in a sectional view
  • FIG. 8 a glass barrel sensor with mechanical scanning
  • FIG. 9 a glass barrel sensor built into a sprinkler.
  • glass barrel sensors are equipped with heating elements or retrofitted.
  • 1 and 2 show that an annular heating element 2 is attached to a glass tube 1 in its lower third.
  • the heating element 2 is arranged in the lower third of the glass tube 1 because of the rising heat. It is designed as an open ring, the inside diameter of which is slightly smaller than the outside diameter of the glass tube 1, and consists of an electrically conductive, elastic material.
  • the heating element 2 has electrical connections 3, to which electrical lines 4 are detachably connected.
  • the heating element When it is pushed onto the glass tube 1, the heating element is slightly bent apart, and when it springs back, it clamps on the glass tube 1, so that the two edges with their connections 3 no longer touch each other with certainty. If the liquid 5 enclosed in the glass tube 1 heats up in such a way that the glass tube 1 bursts, the heating element 2 falls off and thereby detaches from its lines 4. At this moment, the resistance measured via the lines 4 between the two connections 3 changes. This change in resistance is the signal that the glass barrel sensor has released the extinguishing agent outlet opening. For safety, all glass barrel sensors located in its immediate vicinity can now be heated via their heating elements 2 until they burst and also release their extinguishing agent outlet openings.
  • thermocouple 6 passed through the glass tube 1 is shown in FIG. It is therefore in the liquid 5.
  • thermocouple 6 a resistance heating wire can also be used. The temperature of the liquid 5 in the glass tube 1 is continuously monitored via the electrical lines 4.
  • a heating current can be applied via the electrical lines 4, so that the liquid 5 quickly reaches a temperature which causes the glass tube 1 to burst. Thereafter, as already described, all glass tubes 1 in the immediate vicinity can also be heated up to bursting in order to ensure reliable fire fighting.
  • Another advantage of this variant is that when the glass tube 1 bursts, the lines 4 are also disconnected from their connections 3 at the same time, so that the trigger signal is generated even more reliably and is more likely to reach the control center than simply by falling onto the glass tube 1 attached heating element 2, as described for FIGS. 1 and 2, is possible.
  • thermocouple 6 located in the liquid 5 is achieved in that a heating spiral 7, as in FIGS and 5, is located directly in the glass tube 1.
  • thermocouple 6 shown in FIG. 3 its connections 3 are also passed through the wall of the glass tube 1 and are also easily detachably connected to the lines 4.
  • thermocouple 8 shows a third variant of equipping a glass barrel sensor with means for detecting its state.
  • melted thermocouple 8 and FIG. 7 a resistance heating wire 9 melted into the wall of the glass tube 1.
  • the lines 4 are quickly separated from their connections 3 and thus an immediate signaling to the control center.
  • This connection with the glass tube 1 can, however, only be realized in the case of glass tubes 1 to be newly manufactured.
  • FIG. 8 shows the possibility of mechanical scanning of the glass tube 1, which is advantageous in the event of mechanical destruction of the glass tube 1 by means of a pressure tappet 10, as was described in the prior art.
  • the glass tube 1 is held in a sprinkler housing 11 which can be screwed into an extinguishing agent line (not shown) by means of a threaded connector 12.
  • the sprinkler has an impact plate 13.
  • the pressure tappet 10, which is also fastened in the sprinkler housing 11, is operatively connected to a pressure sensor 14. This constantly registers the pressure that is present when the pressure tappet 10 touches the wall of the glass tube 1. At the moment when the glass tube 1 bursts, this pressure drops to zero. This signal is registered in the control center.
  • the glass barrel sensors adjacent to this sprinkler are then destroyed by their pressure tappets 10, so that they release the extinguishing agent exit devices.
  • the advantage of this variant is that no changes need to be made to the glass barrel sensors and only a triggering of a glass barrel sensor destroys the glass tube 1, but not triggering elements such as thermocouples, heating or resistance wires. However, they are unable to provide information about the temperature development in the room.
  • 9 shows a sprinkler equipped with a glass barrel sensor that can be triggered electrically according to the invention. As already described in FIG. 8, this consists of the housing 11, which in this case is screwed upright into the extinguishing agent line by means of its threaded connector 12.
  • the self-triggering sprinkler sensors which are used in a variety of ways in practice, can be converted with relatively little effort, which can provide information about their condition and, in special versions, about the temperature development in their environment.

Abstract

L'invention concerne une installation de lutte contre l'incendie équipée de détecteurs à récipients en verre, par exemple pour des installations de gicleurs d'incendie. Ces détecteurs libèrent les ouvertures de sortie d'agents d'extinction de l'installation en cas d'incendie et comportent un récipient en verre rempli d'un liquide et retenu dans un logement, lequel récipient peut être brisé par une unité de commande par le biais d'un système électrique de déclenchement à distance. L'objectif de cette invention est de produire une installation économique de lutte contre l'incendie, présentant les normes de sécurité élevées d'installations d'extinction commandées par des installations de détection d'incendie, mais pour un coût moindre. Cette invention doit également permettre une détection rapide et locale de l'incendie ainsi qu'une libération immédiate des ouvertures de sortie d'agents d'extinction nécessaires pour arrêter l'incendie. Les frais de maintenance doivent être aussi faibles que sur des installations de gicleurs d'incendie. A cet effet, le système électrique de déclenchement à distance est conçu sous forme de détecteur pour la détection de l'état du récipient en verre (1). Les détecteurs à récipients en verre deviennent ainsi des détecteurs interrogeables et les gicleurs d'incendie deviennent des détecteurs d'incendie intelligents.
