Definitions

  • the invention relates to a fire extinguisher valve and Fire extinguishing device with such a valve.
  • the "FireTrace® system” essentially consists of at least an extinguishing agent container that contains a gaseous pressure medium as a propellant or contains as extinguishing gas, and a special hose that connects to the Extinguishing agent container is connected and through the gaseous Pressure medium in the extinguishing agent container is pressurized.
  • the one under pressure standing special hose is above the potentially fire-hazardous area appropriate. It consists of a specially developed, age-resistant and diffusion-tight polymer material and is designed such that the Hose wall, for example, at a temperature between 100 and 110 ° C bursts open and allows the gaseous pressure medium to escape.
  • the Hose directly to the extinguishing agent container connected. If the hose bursts in the event of a fire, the extinguishing agent flows through the hose to the burst location where it is released.
  • the Hose thus serves both as a trigger element and as a transport line for the extinguishing agent.
  • the hose is by means of a special fire extinguisher valve connected to the extinguishing agent container. As soon as the pressure in the hose drops relative to the pressure in the extinguishing agent container, opens this control valve to release the contents of the extinguishing agent container.
  • a pressure drop in the hose naturally arises if in the event of a fire
  • the hose bursts under the influence of heat.
  • Several fire extinguishing agent containers can be used in the event of a fire can be controlled simultaneously, so that for example in a closed Space a certain concentration of a gaseous extinguishing agent effortlessly can be achieved.
  • the aforementioned fire extinguisher valve includes a valve seat, a membrane-shaped closing element which is assigned to the valve seat, and a release chamber in which the closing element forms a pressure surface.
  • a connecting hole through the closing element connects the Trigger chamber in terms of pressure with the extinguishing agent container.
  • the closing element with its printing area is designed and arranged so that it is Pressure equalization between the extinguishing agent container and the release chamber against the Valve seat is pressed and if there is a pressure drop in the release chamber from the valve seat takes off.
  • the pressure drop in the release chamber is caused by the bursting of the Generated hose that is connected directly to the trigger chamber.
  • Fire extinguisher valves with a closing piston as they are e.g. in the EP-A-0010465 and GB-A-2115905 are also for that "FireTrace® system" suitable.
  • this "FireTrace® system” has been used extremely successfully with extinguishing powders, water, AFFF foam or the new halon exchange gases.
  • the "FireTrace® System” is not suitable for CO 2 as an extinguishing agent. Since the gas pressure in the CO 2 extinguishing agent container is strongly temperature-dependent, there are indeed unacceptable fluctuations in the trigger temperature when the ambient temperature fluctuates. These fluctuations in the triggering temperature are extremely dangerous, above all because a decrease in the triggering temperature is found at a high ambient temperature and an increase in the triggering temperature at a low ambient temperature.
  • From US-A-4,356,868 is a stationary CO2 fire extinguishing system a fusible trigger / fire extinguishing line known.
  • the extinguishing system are the carbon dioxide tanks via a gas distributor and a connecting line connected to a valve control cabinet in which a multi-part valve system is housed.
  • This valve system includes a three way pneumatic valve that normally is closed, as well as a pressure regulator. The latter supplies one common connecting line into which a flow limiter is integrated, both the meltable trigger / fire extinguishing line and the pneumatic one Trigger device on the three-way valve, with carbon dioxide under one reduced pressure.
  • the object of the present invention is to provide a new, compact fire extinguisher valve, the trigger temperature of a Fire extinguishing device of the type described above independent of To make fluctuations in the ambient temperature.
  • a fire extinguisher valve which according to the invention is arranged between the trigger chamber and the trigger connection of the valve, reduces the pressure in the fusible hollow body and weakens the effect of pressure fluctuations in the extinguishing agent container on the pressure in the fusible hollow body which is connected to the trigger connection.
  • the trigger temperature which is determined by the melting behavior of the fusible hollow body and the internal pressure in the hollow body, will thus cause the pressure fluctuations in the extinguishing agent container to be more independent of temperature fluctuations.
  • a fire extinguishing device according to the invention can also be operated with CO 2 as an extinguishing agent, even when there are large fluctuations in the ambient temperature.
  • the fusible to be connected to the trigger port of the valve Hollow body is in most cases a fusible tube attached to its free end is sealed and that above the potentially fire risk Place is attached.
  • the fusible hollow body for example as a small bottle, as rigid pipe network or as a large cushion.
  • the only important thing is and only that the fusible hollow body under a certain Internal pressure bursts at a predetermined temperature (for example 100 ° C) and let the compressed gas escape.
  • the fusible hollow body must of course also have sufficient durability and sufficient be diffusion-tight.
  • the fusible hollow body is advantageous with connected to a pressure relief valve.
  • the extinguishing agent can be an extinguishing powder or an extinguishing liquid, the pressure medium being a propellant gas, for example nitrogen.
  • the extinguishing agent can also be an extinguishing gas.
  • carbon dioxide as an extinguishing agent. It should be noted that this creates an extremely simple, automatically triggering CO 2 fire extinguishing device that does not require any electrical contacts, that works entirely without external energy, that requires little maintenance, that is not prone to malfunction, and that works extremely reliably even under extreme environmental conditions.
  • this automatically-triggering CO 2 fire extinguishing device can be used advantageously for the object protection of switchgear, machine rooms, electric motors and emergency power generators, whereby fluctuations in the ambient temperature from -20 ° C to + 60 ° C must often be expected.
  • any portable or mobile CO 2 fire extinguisher can be integrated into an automatically triggering fire extinguishing device which does not require an external power connection.
  • the proposed fire extinguisher valve advantageously includes one Valve body and a valve cap, with the pressure regulator in the valve cap is installed.
  • a blocking device allows blocking the Pressure regulator in the closed position, so that emptying of the Fire extinguisher is prevented when removing the fusible hollow body.
  • the pressure regulator advantageously has a prestressed spring element, the pressure in the trigger connection of the fire extinguisher valve over the Preload of the spring element can be determined. The pressure in Trigger connection and thus the trigger temperature can then be changed the bias of the spring element can be adjusted.
  • the fire extinguisher valve 10 is screwed onto an extinguishing agent container 12.
  • this extinguishing agent container 12 is, for example, a CO 2 bottle, only the bottle neck being shown in cross section.
  • the gas pressure in the CO 2 bottle is, for example, 60 bar. However, if the ambient temperature rises to 60 ° C, the gas pressure in the CO 2 bottle can rise to 170 to 220 bar, depending on the filling factor.
  • the fire extinguisher valve 10 essentially consists of a valve body 14, as is used, for example, in CO 2 fire extinguishers which can be triggered by hand, and a novel valve cap 16.
  • the valve body 14 comprises a connection piece 18 which can be screwed into the bottle neck of the CO 2 bottle 12.
  • a connecting channel 20 is formed which is directly connected to the interior of the CO 2 bottle 12.
  • the reference number 22 shows an outlet channel for the extinguishing agent, which is arranged in a lateral connection piece 24 of the valve body 14.
  • a valve seat 26, to which a closing element 28 is assigned, is arranged between the connecting channel 20 and the outlet channel 22.
  • the latter is designed as a closing piston which is axially displaceably fitted into a cylindrical chamber 30 above the valve seat. In the valve position shown, the closing element 28 lies with its end face 32 sealed against the valve seat 26, the connection between the connecting channel 20 and the outlet channel 22 being sealed gas-tight via the valve seat 26.
  • the cylindrical chamber 30 is axially through the valve cap 16th closed so that a chamber 34 behind the closing element 28 is separated, which is hereinafter referred to as the trigger chamber 34.
  • this trigger chamber forms the second end face of the closing piston 28 Printing area 36.
  • the closing piston 28 has an axial bore 38 on, which opens centrally into the first and second end faces 32 and 36. about this bore 38 can be the same pressure in the trigger chamber 34 as in connection channel 20. Since the cross section of the trigger chamber 34 is larger than the cross section of the seat 32, acts - at the same pressure in Tripping chamber 34 and connection channel 20 - a hydrostatic closing force in Direction valve seat 26 on the closing piston 28, which seals on the valve seat 26 is present.
  • a pressure regulator 42 is installed, which via a Channel 44 is connected to the trigger chamber 34.
  • the Pressure regulator on a trigger connection 46 to which a so-called “FireTrace®” hose 48 is connected. It is a Hollow body which is designed so that it is under a certain internal pressure bursts when its wall temperature at a point a certain limit exceeds.
  • the internal pressure in the hose 48 is determined by the pressure regulator 42, which is connected between the trigger chamber 34 and trigger terminal 46. This can thus the higher gas pressure in the extinguishing agent container 12 reduce a lower internal pressure in hose 48, which is the corresponds to the desired trigger temperature. Does the gas pressure change in the Extinguishing agent container 12, the pressure regulator 42 maintains the internal pressure in the hose 48 largely constant, or at least reduces the extent of Pressure fluctuations in the hose 48 significantly.
  • Figure 1 shows, for example, a particularly simple spring-loaded pressure regulator 42.
  • This pressure regulator has a first chamber 50 which communicates with a second chamber 54 via a connection bore 52 connected is.
  • An actuating piston 56 is axially displaceable in the second chamber 54 fitted.
  • a shaft 58 that has a smaller diameter than that Has connecting bore 52 connects the actuating piston 56th mechanically with a closing body 60 in the first chamber 50.
  • This Closing body 60 which is equipped with a sealing ring, is a seat assigned to the opening of the connecting bore 52 in the first Chamber 50 surrounds. The free cross section of the seat is much smaller than the cross section of the second chamber 54.
  • a spring 62 exerts on the Actuating piston 56 a spring force in the direction of the first chamber 50.
  • This spring 62 is biased by a screw-in cap 64. Under the spring force lifts the closing body 60 from its seat, so that gas from the first chamber 50 via the connection bore 52 into the second chamber 54, and can flow into the hose 48 via the release connection 46.
  • a pressure builds up on the Actuating piston 56 exerts a hydrostatic force. This hydrostatic Force opposes the spring force and ultimately moves the Actuating piston 56 in the direction of the cap 64 until the closing body 60 seals rests on its seat.
  • a pressure increase in the bottle 12 cannot occur now affect the pressure in hose 48 more.
  • the hose 48 bursts as intended in the event of a fire, the pressure in the second chamber 54 drops to ambient pressure and the spring 62 pushes the actuating piston 56 in Direction of the first chamber 50 so that the closing body 60 from its seat takes off.
  • the spring 62 must of course overcome the hydrostatic force which the gas pressure in the chamber 50 exerts on the closing body 60. Now can the gas from the trigger chamber 34 via the channel 44, the chamber 50, the connecting hole 52 and the trigger port 46 in the burst Flow in hose 48 and escape into the environment. Because the gas flows out of the trigger chamber 34 faster than new gas via the Flows through bore 38, the closing piston 28 is the pressure in the Bottle 12, as described above, pressed against the cap 16. It can now no more gas flow into the trigger chamber 34, so that the valve to for completely emptying the bottle 12 remains open.
  • This Blockkiervorraum 66 which is in the axial extension of Pressure regulator 42 is installed in the valve cap 16 includes, for example Set screw 67 against the closing body 60 in the screwed-in position squeezes his seat. A sealable cap 68 prevents access to the Set screw 67. In the blocked position of the pressure regulator 42, the Hose 48 can be removed from the trigger connection 46 without the valve triggers.
  • a pressure relief valve 70 connected to the hose 48.
  • the above-described fire extinguisher valve 10 is in an alternative Execution of the fire extinguishing device according to the invention involved.
  • a "FireTrace®” hose 48 ' is directly on the nozzle 24 of the valve 10 connected.
  • This "FireTrace®” hose 48 'forms the fusible closed hollow body made with the trigger connection 46th of the fire extinguisher valve 10 is connected via a connecting line 100.
