Definitions

  • the invention relates to a method and a device for operating a fire extinguishing dry sprinkler system.
  • Dry sprinkler systems are known. They become multiple used in rooms where there is a risk of frost in order to avoid being in contact with extinguishing water filled sprinkler pipe network freezes.
  • the sprinkler pipe network is operated by means of a compressor preferably filled with compressed air at 2.5 bar. Between the sprinkler pipe network and the extinguishing water line is connected to a dry alarm valve, the valve plate kept closed due to a pressure balance between air pressure and water pressure becomes. If a sprinkler opens in the event of a fire, the compressed air escapes from the Sprinkler pipe network and thus from the air chamber of the dry alarm valve.
  • the invention has for its object to provide a device with which Sprinkler pipe network vented faster and thus the full fire water performance faster queues at the sprinklers.
  • This object is achieved in that the ventilation of the piping system and the The alarm valve is opened via separate pneumatic devices, the Quick opening for venting the piping system before the quick opening of the dry alarm valve.
  • the guideline has been changed in such a way that the water has to reach the sprinkler with the same volume of air within 60 seconds.
  • the sprinkler group must be divided and each group, with a reduced volume, assigned a separate dry alarm valve station will.
  • a dry sprinkler system 1 consists of a piping system 2, which by a Dry alarm valve 3 via a sprinkler supply line 4 and a distribution line 5 the sprinkler lines 6 to 8 with the sprinklers 9 is guided. From there is a pipeline 10 led to a quick exhaust. Between the dry alarm valve 3 and the extinguishing water line 12, a gate valve 11 is provided. Means a compressor 13, air is introduced into the filling line 15 via an intake port 14 and the piping system 2 filled with compressed air. Inside the valve body 16 of the dry alarm valve 3, a valve seat 17 with a valve disk 18 is provided, which is kept shot from the air pressure from the supply line 4. So that is the upper space 20 of the dry alarm valve 3 filled with compressed air.
  • a locking device 19 is also provided, which has an atmospheric part 22 and forms a water space 21. Below the locking device 19 and the atmospheric part 22 is the dry alarm valve with the gate valve 11 open Fire water filled. The pressure of the extinguishing water and the pressure of the air in the piping system are aligned so that the valve disc is closed in standby mode is.
  • a nozzle 33 is provided, which is connected via an air line 36 connected to a socket 32 of a pneumatic diaphragm quick opener 23 is.
  • the air line 36 is with a constant pressure regulator 41, a shut-off valve 40, a ball check valve 39 and a throttle valve 38 with a throttle cross section 0.40 provided.
  • the vessel 24 of the quick opener 23 is in the head area with a manometer 25 and provided in the lower area with a membrane 26 which is between two Flanges is clamped.
  • a membrane pot 29 is connected to the membrane 26 a spring-loaded valve plate 28 in the housing of a quick opening valve 27 is assigned is.
  • the lower opening of the diaphragm cup 29 can be closed with the valve plate 28.
  • the quick opening valve 27 is provided with two connecting pieces 30 and 31, wherein the connector 30 is connected to the air line 36 by means of a connecting line 37 and an opening line 42 provided with a shut-off valve 43 on the connection piece 31 is provided, which on a nozzle 34 of the atmospheric part 22 of the dry alarm valve 3 is connected.
  • An alarm line 44 goes along with the opening line 42 a control valve 45 and a manometer 46, of which an alarm line 48 is led to an alarm device 47.
  • the air part 20 of the dry alarm valve 3 is still with a nozzle 35 for connecting a control line 86, with a shut-off valve 87 and a manometer 88 are connected.
  • To the sprinkler line 6 is a test line 83 with a Test valve 84 and a throttle valve 85 connected. These are for implementation provided by tests.
  • the pipeline 10 is to a connecting piece 58 of a pneumatic Membrane quick opener 49 performed.
  • the quick opener 49 also consists of a housing 50 with a manometer 51 and a membrane 52 attached between flanges to which a membrane pot 55 is attached. This is in turn with a spring-loaded valve plate 54 of a quick-opening valve 53, this quick-opening valve also being assigned is provided with connecting pieces 56 and 57. From the connecting piece 56 is an intermediate line 76 branches off, which is connected to the pipeline 10. In this section is the pipe 10 with a shut-off valve 59, a dirt trap 60, another Shut-off valve 61, a further dirt trap 62 and the throttle valve 65 with a throttle cross section 6.0 provided. Between the connection of branch line 76 and the Throttle valve 65, a ball check valve 64 is provided.
  • Ball valve 78 From Connection 57 of the quick-opening valve 53 goes to a connecting line 77 Ball valve 78 from which a drain line 79 is connected to a Collecting device 80 is guided. In addition, the ball valve 78 with a Drain line 81 and a drain valve 82 provided.
  • the pipeline system 2 is filled with compressed air by means of the compressor 13.
  • the dry alarm valve 3, the gate valve 11 and the valves 59, 61, 67 40, 43 84, 72 and 82 are closed for the air filling.
  • the pipeline system 2 is filled with air via the lines 4 to 10 to the closed valve 59 and via the socket 33 to the closed valve 40.
  • the valves 59 and 61 are opened so that the air flows into the container 50 of the quick opener 49 and via line 76 and nozzle 56 into the quick open valve 53 and thus exerts pressure compensation on the membrane 52 of the quick opener 49.
  • the throttle 65 ensures a low air speed, so that the ball of the ball check valve 64 is suspended so that the air can flow and thus fill the container 50.
  • valve 67 is opened. This creates a pressure equalization in the diaphragm valve 68 and keeps it closed.
  • the individual parts 77 to 82 are depressurized.
  • the valve 40 is opened, so that the container 24 of the quick opener 23 is filled with air with the quick open valve 27 and pressure compensation is thus exerted on the membrane 26.
  • the opening line 42 is depressurized with the valve 43 open up to parts 44 to 48.
  • the gate valve 11 is opened. The extinguishing water flows to below the atmospheric part 22. This ensures pressure equalization on the valve plate 18.
  • the 3-way control valve 45 is opened Active "is set so that the sprinkler system is now in standby mode.
  • the quick opener 23 opens the different cross sections of the chokes 65 and 68 delayed, in the seconds range, later than the quick release 49.
  • the pressure in the container 50 degrades more slowly due to the smaller throttle 65, so that the remaining one Pressure of 2.3 bar in the quick opener 49, the quick opening valve 53 opens quickly.
  • the pressure from the container 24 of the quick opener 23 flows through the larger throttle 38 faster than from the container 50, so that the pressure of 2.2 bar on the membrane 26th the quick opening valve 27 compared to the quick opening valve 53 in the second range opens later.
  • valve 27 is open, the air flows via lines 37 and 42 into the atmospheric part 22 of the quick opening valve 3 and opens the valve plate 18, so that fire water flow into the piping system and the sprinkler 9 to Deletion can drain.
  • the water first flows up to the ball check valve 64. Due to the fast flowing water with high pressure, the ball floats and closes the valve 64. At the same time, the ball floats in the check valve 78 also closes and also closes this valve. Furthermore flows above and below the Diaphragm of the valve 68 the extinguishing water and also closes this valve by pressure equalization. This means that the extinguishing water can only flow off via the sprinkler 9.
  • the system can be put back into the Standby state, as previously described.
