Definitions

  • the invention relates to a fire extinguisher with a container containing an extinguishing agent and a holder for a propellant gas cartridge for filling the container containing the extinguishing agent with propellant gas and an actuating mechanism which has an actuating member for actuating a spring-loaded valve pin which is rigid with a plunger for opening the propellant gas cartridge is connected and controls a valve for releasing the extinguishing agent acted upon by the propellant gas, a safety element being arranged between the actuating member and the spring-loaded valve pin for locking the actuating member and the securing element for releasing the locking device from the space between the actuating member before the first start-up of the fire extinguisher and the valve pin is removable.
  • Fire extinguishers of this type are known.
  • the securing element must first be removed before the fire extinguisher is put into operation and then the actuating mechanism must be acted on for a short time, so that the propellant gas cartridge is opened and the container containing the extinguishing agent is filled with propellant gas.
  • the propellant gas not only flows into the container but also out of the container, since the valve is opened at the same time. Therefore, the opening process for the LPG cartridge should be as short as possible be so that after opening the propellant cartridge, the propellant initially only fills the container in which the extinguishing agent is located and which is automatically closed by the spring-loaded valve pin.
  • the extinguishing agent, driven by the propellant gas in the container is to be sprayed with the fire extinguisher only after a subsequent second actuation.
  • the propellant gas cartridge is automatically pulled out open. This process also takes place in a relatively short time, since the pulling out of the securing element takes place more or less abruptly due to the resistance due to the spring-loaded valve pin and thus no propellant gas is lost to the outside, which is now used exclusively to fill the container.
  • the advantage is also achieved that the first time the actuating mechanism is pressed, the extinguishing process can be started immediately, because there are usually at least two up to 3 seconds between unlocking and pressing the actuation mechanism, a time sufficient to completely fill the container with propellant gas. This also takes account of the second requirement.
  • the securing element preferably has a ring on which it can be pulled out. This ring virtually prompts the user of the fire extinguisher to pull out the safety element before commissioning.
  • the safety element is expediently clearly differentiated in color from the fire extinguisher.
  • the invention will now be explained in more detail using an exemplary embodiment and with reference to the accompanying drawing.
  • This container is on the thread 10 of a molded part surrounding an actuating mechanism 12 is screwed on.
  • An O-ring 14 is used to seal the screwed-on container.
  • a holder 16 for a propellant gas cartridge 18 is screwed into the molded part of the actuating mechanism.
  • the propellant gas cartridge 18 may be a commercially available carbon dioxide cartridge.
  • the actuating mechanism comprises the one-piece molded part made of plastic, which has a handle 20.
  • a valve pin 22 In the molded part 12 there is a valve pin 22, at the lower end of which a plunger 24 for breaking open a rupture disk (not shown in more detail) of the propellant gas cartridge 18 is rigidly arranged.
  • the slidably mounted in the molded part 12 valve pin 22 is biased by a spring 26 upward, as shown, so that a valve seal 28 formed as an O-ring and surrounding the valve pin 22, which is held in a groove of the valve pin, in a Bore trained valve seat engages. This closed state of the valve is shown in the drawing. Below the valve seat, the bore widens at 30 and is open via channels 32 in the holder 16 to the interior of the container, not shown.
  • the bore has a tapered section 34 which surrounds the valve pin 22 at a distance. Shoulders 38 on valve pin 22 guide the valve pin in the bore.
  • the tapered section 34 of the bore is connected to an outlet opening 40 for spraying the extinguishing agent in the container when the valve seal 28 engages downward from the valve seat in the enlarged bore section 30 and thus opens the valve.
  • actuating lever 44 Arranged on the molded part 12 is an actuating lever 44 which can be pivoted about the axis 42 and which has an actuating member 46 with which the valve pin 22 can be pressed downward into the open valve position against the force of the spring 26, the plunger 24 simultaneously into the propellant gas cartridge 18 moves.
  • a wedge-shaped securing element 48 is located between the actuator 46 and the valve pin 22 and has a ring 50 with which it can be pulled out of the space between the actuator 46 and the valve pin 22. Since the end of the securing element 48 opposite the ring is thicker and decreases in thickness towards the valve pin 22, on the one hand that can
  • Securing element 48 can be pulled out relatively easily after loosening a tab 52 at the end opposite the ring 50, the tab 52 being released simply by the user of the fire extinguisher pulling jerkily on the ring 50 and secondly by the thick end of the wedge-shaped securing element the valve pin 22 pressed against the spring 26 so far that the plunger 24 pierces the rupture disk of the propellant gas cartridge 18.
  • valve seal 28 Due to the jerky movement resulting from the tab when pulling out the securing element 48, the valve seal 28 only briefly releases the flow path of the propellant gas to the outlet 40, which can flow into the container interior via lateral bores 54 in the holder 16 even when the valve is closed.
  • the valve pin is rounded at its upper end.
  • the fire extinguisher can be used to extinguish the first press of the actuating lever 44.
  • the actuator 46 then immediately presses the valve pin 22 downward, so that the valve 28 is opened and the propellant gas can spray the extinguishing agent over 32, 30, 34 and 40.
  • the securing element 48 is mounted displaceably on both sides in the molded part of the actuating mechanism, the guides of the molded part and the lateral sliding surfaces of the securing element 48 likewise being able to run in the same direction in a wedge shape and in an adapted manner to one another.

Abstract

Selon l'invention, dans un extincteur comportant un récipient, contenant un agent d'extinction, et un logement, destiné à une cartouche de gaz propulseur, ainsi qu'un mécanisme d'actionnement, un élément de sécurité (48) en forme de coin est placé entre l'organe d'actionnement (46) et la tige (22) d'une soupape commandant la libération de l'agent d'extinction soumis à l'action du gaz propulseur, de sorte que, lors du retrait de l'élément de sécurité, la cartouche de gaz propulseur (18) soit ouverte automatiquement au moyen d'un poinçon (24) monté sur la tige de soupape. De cette façon, il est garanti qu'avant le premier actionnement de l'extincteur, le récipient contenant l'agent d'extinction soit soumis à l'action du gaz propulseur provenant de la cartouche de gaz propulseur (18).
