Definitions

  • the innovation concerns a gas high-pressure fire extinguishing system, at of the gaseous extinguishing agent under high pressure in one or several gas cylinders is stored, each with one Quick opening valve are provided on the connecting hoses are connected to a manifold and a pressure reducing device and from there to single-zone extinguishing systems one or, in the case of multi-zone extinguishing systems, to several zone valves and from there via extinguishing lines to extinguishing nozzles are.
  • Such fire extinguishing systems have so far been operated with an extinguishing agent stored at 200 bar in high-pressure gas bottles.
  • the extinguishing agent is stored under high pressure for economic reasons.
  • High-pressure gas bottles for an extinguishing system require less space than an extinguishing system with low-pressure gas bottles. For example, with m 2 floor space prices of DM 6,000 and more in office skyscrapers, every m 2 saved is a profit.
  • the number of bottles can be significantly reduced compared to low-pressure gas bottles. With fewer gas bottles, the transport, assembly and maintenance costs are significantly lower.
  • Extinguishing nozzles with a gaseous extinguishing agent at a pressure to pressurize from 200 bar is uneconomical and also dangerous, if the extinguishing agent with the high pressure from the Extinguishing nozzles emerges.
  • the Extinguishing agent behind the collector pipe to a pressure of 60 bar or less reduced. This also enabled the pipe network and the extinguishing nozzles are manufactured more economically.
  • the innovation is based on the task of a gas high-pressure fire extinguishing system the storage of the gaseous extinguishing agent by using the simplest means of 200 bar to switch to 300 bar.
  • This object is achieved in that between the quick opening valve and the previous pressure reducing device upstream further pressure reducing device is provided.
  • the additional early pressure reducing device immediately behind the quick opening valve the high pressure mass discharge from a high pressure gas bottle minimizes a low level system pressure. So becomes Example of gas pressure in the first stage from 300 bar to 200 bar reduced and the extinguishing gas occurs with this reduced Pressure into the high pressure manifold. In the pressure reducing device the gas pressure will rise to 200 bar in the second stage Reduced 60 bar or less. From the manifold, the previous one "200 bar technology" can be used without modification, however with the exception that an additional safety device must be installed for pressures above 240 bar.
  • the purpose is preferably at the end facing away from the extinguishing nozzles of the collector pipe is an extension line that is led outside provided in which a safety device, such as a rupture disc or a safety valve is installed.
  • This Safety device must be dimensioned sufficiently to ensure that in the event of a malfunction the gas mass flow is certain got outside. The resulting radiance can still by atomization, diversion or the like. be minimized.
  • the early additional pressure reduction can be immediately behind the quick-opening valve or immediately in front of the manifold be made. This pressure reduction is done by a Cross-sectional change using a throttle disc with a Bore of preferably 10 mm in diameter. This calculated The bore of the extinguishing system is designed according to the application.
  • the early pressure reduction using one of the throttling devices has the further advantage that in a single-zone fire extinguishing system dispenses with the high-pressure manifold and a low-pressure manifold can be used for this. Because in this case, the pressure is reduced before Collector tube from 200 bar to 60 bar or less. For this A high pressure manifold is not required for pressure. As a result the extinguishing agent can be used directly without further pressure reduction to the extinguishing nozzles.
  • the previously known gas high-pressure fire extinguishing systems are included a so-called "200 bar technology" operated.
  • the gas bottles for the extinguishing agent with a gas pressure of 200 bar filled.
  • the quick opening valves, the connecting hoses, the manifold and the distribution lines with the range valves including the pressure reducing device costly for an operating pressure of 240 bar and a test pressure of 750 bar.
  • the gas bottles 2 to 4 of the multi-range system 1 with the Quick opening valves 5 to 7 are with a gas pressure of 300 bar filled.
  • Either the quick opening valves are 5 to 7 with pressure reducing devices 25 to 27 or the high pressure manifold 11 provided with pressure reducing devices 28 to 30. Only one of the two pressure reducing devices, i.e. 25 or 28 - see Figure 2, is installed.
  • Via connection hoses 8 to 10 are the quick opening valves 5-7 with the Collector tube 11 connected.
  • the end of the collecting pipe 11 is through the hall roof 41 in Free guided extension line 38 connected into the a disc holder 40 with a rupture disc 39 as a safety device is installed.
  • the quick opening valves 5 to 7 are based on the example of the Quick opening valve 5 described in Figure 2.
  • the quick opening valve 5 consists of a valve body 43, which by means of a lower threaded bore 44 on the neck 45 of the Gas bottle 2 is screwed on.
  • a control piston 46 with a Piston plate 47 and a seal plate 48 with seal 49 is installed inside the valve body 43.
  • springs 50 the sealing plate 48 is pressed against the seal 49 and thus the quick opening valve 5 kept closed.
  • a upper inlet opening 51 is also by means of a valve cap 52 Connection piece 53 closed for a control line 55.
  • an outlet bore 54 is provided for the extinguishing agent, which merges into a nozzle 31.
  • a throttle disc 33 is installed with a bore.
  • a connecting piece 35 as a backflow preventer is the connecting hose 8 to the quick opening valve 5 connected.
  • the throttle device 28 is connected to the high pressure manifold 11 and consists of the Port 32 and the connector 36 for attaching the other end of the connecting hose 8.
  • a throttled disk 34 In the socket 32 is a throttled disk 34 with a bore and one Check valve 42 installed.
  • a fire alarm control panel is used to control the fire extinguishing system 1 (BMZ) 56 provided, on the one hand one of one Fire detector 58 outgoing control line 57 and on the other hand a control line 55 leading to the quick opening valve 5 are connected.
  • BMZ fire extinguishing system 1
  • the gaseous extinguishing agent is at 300 bar in the gas bottles 2 stocked up to 4.
  • the quick opening valves 5 are closed.
  • the BMZ 56 is activated via the fire detector 58 and from there on the control line 55 a pressure the piston plate 47 of one or more quick opening valves 5-7 exercised.
  • the piston plate 47 after overcoming the spring pressure of the spring 50 pressed down and thus the controlled quick opening valve 5-7 opened.
  • the extinguishing agent flows - depending on which throttle device is installed - either by the throttle device 25 or 28, whereby it is reduced to 200 bar, into the collecting pipe 11 and on to the pressure reducing devices 18 -20.
  • the pressure of the extinguishing agent a second time to 60 bar or less reduced. With this pressure, the extinguishing agent arrives via the low-pressure pipe network 21-23 to the extinguishing nozzles 24.
  • the distribution lines are not required 13,14 with the range valves 16,17, Pressure reducing devices 19, 20 and the extinguishing lines 22, 23 with the extinguishing nozzles 24.
  • the extinguishing agent is out the high-pressure manifold 11 only via the distribution line 12 with the range valve 15 and the pressure reducing device 18 through the extinguishing line 21 to the extinguishing nozzles 24.
  • the manifold can 11 compared to the previous systems as a low-pressure manifold are formed, the pressure reducing device 25 den Pressure of the gaseous extinguishing agent from 200 bar to 60 bar or less reduced. In this case there is no costly High pressure pressure reducing device 18 and the expensive high pressure manifold.
