Definitions

  • the invention relates to a tripping unit for an extinguishing system with at least one extinguishing agent container to which at least one extinguishing medium line is connected, and wherein at least one extinguishing agent nozzle is provided which is connected to the extinguishing medium line, wherein upon activation of the extinguishing agent container, an extinguishing agent is releasable and by the extinguishing medium line can be guided to the extinguishing agent, wherein the activation of the extinguishing agent container can be triggered by a pressure increase in the extinguishing medium line, wherein the triggering unit comprises an opening element which triggers the pressure increase in the extinguishing medium line.
  • the trip unit is used for extinguishing systems with the goal to protect people and goods in case of fire.
  • the invention has for its object to further develop a trip unit so that it is also suitable for high and aggressive air pollution polluted jobs.
  • the invention provides a dirt-resistant solution.
  • the invention is based on the idea not to connect the trip unit by a T-piece with the extinguishing agent line, but to integrate them quasi in the extinguishing agent line.
  • the trip unit can be designed as a tubular body and aligned axially to the extinguishing medium line.
  • a suitable outer skin of the tubular body provides a dirt and korrosionsunan memories element.
  • the tripping elements or tripping units according to the invention are integrated as a complete device directly into the line and flowed through by the extinguishing agent.
  • a pressure accumulator may be arranged, which with a Puncture device can be in operative connection.
  • the accumulator can be held spring loaded on one side and held and guided on the other side with its neck-like end in an annular body.
  • This annular body may be made of eutectic solder or may be attached thereto.
  • the special feature of the solder is that it is relatively strong and liquid at a defined temperature, eg 90 ° C or 70 ° to 75 ° C and releases the spring-loaded pressure accumulator with respect to a movement along its longitudinal axis, so that through the Einstech adopted the built-in line pressure accumulator is opened and a pressure wave in the system triggers.
  • the annular body which can hold the pressure accumulator and e.g. either consists of eutectic solder or is attached by means of eutectic solder on the copper body may have corresponding flow openings, so that it can be flowed through by the extinguishing agent, so that the extinguishing agent flows around the pressure accumulator.
  • the activation element may also be defined as an indirect opening element and be an annular body which is designed for activating or releasing the pressure accumulator or for opening with the aid of the puncturing element.
  • the actual opening function is controlled by another element, e.g. reached a needle.
  • the activation element is firmly connected in a normal state with an inner wall of a pipe section.
  • a normal state is always when there is no fire.
  • the activation element is then designed such that in case of fire above a defined temperature of the pipe section, the activation element of the inner wall of the pipe section is releasable and is under spring action, that it releases the pressure accumulator.
  • the triggering temperature may refer to the surface of the corresponding line piece and is preferably about 70 ° to about 90 °.
  • the activating element is of annular design and connected to a neck of a pressure vessel located axially in a pipe section and serving as an accumulator, preferably indirectly.
  • the activation element then has a double function. On the one hand there is a movement of the pressure vessel free and on the other hand it leads this within the pipe section.
  • the activation element is then also a guide element, so that components and costs are saved.
  • the pressure vessel is located with its neck opposite the container bottom to a compression spring.
  • the compression spring presses the pressure vessel and displaces it along its longitudinal axis in such a way that the neck or an upper side of the neck is moved in the direction of a spike-type piercing element or pressed against the piercing element.
  • a medium under pressure in the pressure accumulator medium escape through the puncturing element in the extinguishing agent line.
  • This will activate activation of the extinguishant container, e.g. is arranged at the end of the extinguishing agent line, thereby achieved by the pressure change effected in the extinguishing medium line.
  • the extinguishing agent can then flow out of the extinguishing agent nozzles and extinguish the fire.
  • the activation element consists of one, in particular eutectic, solder. That the entire body can be made of this material.
  • the activation element may also comprise a solder. It can e.g. consist mainly of copper and be executed with a soldered surface, said surface is also soldered to a pipe inner wall.
  • the activation element can therefore be fastened or soldered to the solder on the line piece. Namely, the solder becomes liquid above the defined temperature, so that the activating element can come loose from the inner wall of the pipe section and release or open the pressure accumulator.
  • the annular activation element comprises an outer groove in which the solder is embedded.
  • First solder material is heated, liquefied and filled in the groove.
  • the annular body can then be mounted with the cooled solid, solder in the pipe section. Subsequently, the surface of the pipe section can be heated, so that the solder melts again and enters into a cohesive solid connection with the inner surface of the pipe section during cooling.
  • each connecting element is in particular disc-shaped and is provided with at least one, but preferably several, for example, four flow openings. All fasteners are in cross section to the pipe section.
  • each connecting element is provided with a central mounting opening.
  • the first connecting element carries a pressure spring lying in the longitudinal direction of the line piece. This is preferably held by an axial, bolt-shaped spring holder. The spring is practically wrapped around the pen and partially protrudes from this.
  • the spring holder is attached to the first connecting element and points in the direction of the pressure vessel.
  • the second connection element is arranged between the annular activation element and the neck of the pressure vessel. This element connects the neck with the activation element or the annular body.
  • the third connecting element carries the piercing element, which is directed to the neck of the pressure vessel. All three connecting elements can thus be made identical, so that only one production tool is required.
  • the component fulfills all three fastening functions, ie attachment of the spring, attachment of the pressure vessel neck and attachment of the piercing element. As a result, storage costs can be saved.
