  • the open extinguishing nozzles and the exciters are mounted in the frost zone.
  • DE 196 01 777 A1 describes a fire-extinguishing system with a pressurized gas-filled sprinkler drying tube network, which is connected to an extinguishing water line.
  • the sprinkler drying pipe network forms an excitation line, which is monitored by a differential pressure switch.
  • the extinguishing water valve which displaces the air from the exciter system in the event of triggering, is put into operation electrically or pneumatically-hydraulically.
  • the sprinklers also form the exciters and the nozzles for spraying the extinguishing water.
  • an open extinguishing system is described with connected to a sprinkler line, open extinguishing nozzles. To stimulate another sprinkler pipe network is connected with closed quick-opening sprinklers. For frost-prone areas these extinguishing systems are not provided.
  • DE 297 15 451 likewise describes a sprinkler system with a compressed air-filled sprinkler pipe network.
  • the sprinkler pipe network is connected to an automatic flushing device, through which a certain amount of air is released from the sprinkler pipe network into the open on a regular basis.
  • the supplied dry air should transport moisture out of the pipe system and avoid corrosion in the pipe system. This drying system is also suitable for frost-prone areas.
  • the invention has for its object to provide a fire extinguishing system with open extinguishing nozzles, in which the lying in the frost areas stimulator and extinguishing nozzles are protected against Eispfropfen Struktur with constipation or damage, and with the same time the triggering process for the extinguishing agent is accelerated in case of fire.
  • This object is achieved in that the extinguishing valve is held by the pressure of a pneumatic control system in the closed state, that the stimulator-containing stimulator line is part of a pressurized cryoprotectant containing hydraulic control system, and that the pneumatic control system connected by at least one check valve to the hydraulic control system is.
  • a particular embodiment of the invention is seen in that the exciter line of the hydraulic control system is associated with a container via a supply line, which is filled with compressed air and cryoprotectant and provided with a shut-off valve and a check valve supply line has a bypass in the region in the supply line one or two water stop valves are provided, and that in the exciter line behind the junction with the supply line one or two check valves are installed, that the exciter line is connected upstream of the check valve at a connection point with the compressed air supply line, and that of the with a Throttle check valve provided compressed air supply line bypass is guided to a quick exhaust.
  • the required operating measures can be optimally performed.
  • the commissioning with the filling process and the establishment of the operating condition, as well as the triggering process in case of fire with the simplest means can perform.
  • the pressure differences caused by temperature fluctuations in the stimulator tube network are compensated by the air cushion in the pressure-air / antifreeze container. This compensation, via an equal-equal bore in the check valve; which is installed in the supply line for the antifreeze.
  • a container 1 is filled with compressed air and antifreeze.

  • Another test line 28 is led to a pressure decrease signaling switch 27. Die.Anreger Koch 20 is connected via a shut-off valve 29 with a check valve 30. Again, a second check valve 31 is provided for safety reasons.
  • the filling limit of the cryoprotectant is designated.
  • the system parts shown above the filling limit 61 relate to the hydraulic control system 60.
  • the actual erase unit is described below, which i.a. consists of the single-chamber valve 50 with the control piston 51, the clamping bridge 52 as a closure member and the toggle 53. Furthermore, the one-chamber valve 50 is connected, on the one hand, to a gate valve 54 and a dissolving water line 55 and, on the other hand, to an extinguishing line 56 and a nozzle tube net 57 with open nozzles 58. Parts of the extinguishing line 56, and the nozzle tube network 57 with the nozzles 58 are also outside the. Frost limit 64 mounted. In the operating state of the fire extinguishing system, the gate valve 54 is opened and the one-chamber valve 50 is closed by means of the clamping bridge 52, wherein the toggle lever 53 locks the clamping bridge.
  • a compressed air supply line 32 is connected to a compressed air source 32 a with a compressor and guided to the control piston 51 of the single-chamber valve 50.
  • a check valve 33 and a throttle check valve 34 is installed with a 0.30 mm throttle opening.
  • the extended exciter line 20 b which is on the other hand connected to the check valve 31.
  • 65 indicates the filling limit for the compressed air.
  • a control line 32b goes off, which branches off on the one hand in a measuring line 37 with a pressure gauge valve 38 and a pressure gauge 39 and on the other hand in an excitation line 36 with a manual exciter valve 40.
  • a bypass line 42 which is provided with two shut-off valves 43 and 44, is connected at a connection point 41, which is led to a rapid exhaust fan 45 with a manometer 66.
  • a diaphragm 46 and a throttle opening 47 is installed, which divides the quick exhaust 45 into an upper diaphragm space 62 and a lower vent space 63.
  • the bypass line 42 is connected to the venting chamber 63.
  • a shut-off valve 48 is provided with an adjusting lever 49, which acts on the shut-off valve 48 by means of the membrane 46 and keeps it closed in the operating state.
  • the fire extinguishing system according to the invention is set up such that both the startup and the tripping operation can be performed.
  • the commissioning of the fire extinguishing system begins with a filling process and a measure to establish the operating state.
  • the shut-off valves 14, 15 and 17a are opened.
  • the shut-off valves 22 and 29 are closed.
  • the supply line 13 with the bypass 17 and the exciter lines 20 and 20a are filled up to the shut-off valves 22 and 29 with the antifreeze to 6 bar operating pressure, which is displayed on the manometer 26.
  • the exciter lines 20 and 20a are vented via the vent valve 22 and at the same time performed a functional test of the pressure-decrease signaling switch 27.
  • the filling process is completed up to the filling limit 61.
  • the check valve 30 restrains the hydraulic control means.
  • the shut-off valve 33 is opened and the compressor of the compressed gas source 32 a is turned on.
  • the hydraulic control system 59 fills with an operating pressure of 4.5 bar.
  • the single-chamber valve 50 is locked and kept closed by means of the control piston 51 when the gate valve 54 is closed.
  • the supply line 32 is filled with the throttle check valve 34 with compressed air.
  • the lines 20b, 37 and 36 are filled with compressed air.
  • the fire extinguishing system is set up after closing the shut-off valve 43 and ready by opening the gate valve 54 for the application.
  • a stimulator 21 When a stimulator 21 is triggered in case of fire, e.g. when opening a sprinkler, the compressed air antifreeze flows over the open exciter 21.
  • the installed in the supply line 13 water stop valves 18 are automatically activated by pressure drop (closed) and prevent further inflow of cryoprotectant in the Anregerrohrnetz 20 and 20a.
  • the cryoprotectant also flows out of the test line 24, so that the pressure-loss signaling switch 27 effects a pressure drop to a reporting point, e.g. a fire station or the fire department.
  • the pressure reduction in the hydraulic control system 60 causes a pressure reduction in the pneumatic control system 59, because the check valves 30 and 31, compressed air flows into the excitation line 20.
  • This pressure reduction activated at an operating pressure of 4.2 bar the quick exhaust 45.
  • the throttle opening 47 the compressed air flows from the venting chamber 63 faster As a result, the membrane 46 pushes the lever 49 down and opens the butterfly valve 48.
  • the entire compressed air of the pneumatic control system 59 flows completely through the drain line 67 from.
  • the control piston 51 is relieved via the line 32, whereby the toggle lever 53, the locking of the clamping bridge 52 cancels and thus the single-chamber valve 50 is opened by the pressure of the extinguishing water.
  • open gate valve 54 the extinguishing agent flows into the nozzle pipe 57 and thus into the open extinguishing nozzles 58. With these measures, a rapid release of the single-chamber valve 50 is achieved.
  • a manual stimulator valve 40 is provided at the end of the stimulator line 36. If the valve 40 is opened by hand, the compressed air flows from the lines 32, 32b and 36 quickly, so that relieved in a few seconds, the control piston 51 and thus the one-chamber valve 50 is opened.
