Definitions

  • the invention relates to a fire shut-off device for Ventilation systems for buildings, with a valve housing, in which is a gate valve from an open position its own weight in a shut off a connecting piece The closed position can be lowered.
  • Ventilation systems are used to vent several buildings Rooms that are usually connected to a common ventilation line are connected. According to the fire protection requirements it must be ensured that a transmission of fire and Smoke from one room of a building to other rooms is prevented. Fire barriers at the connection of the individual ventilation lines serve to connect the connected Shut off the ventilation line as soon as a temperature increase that occurs due to a fire in the room in question lets close.
  • the gate valve of the fire shut-off device is raised in its by a trigger device Open position held. Once the trigger device responds as a result of an increase in temperature, it gives the Gate valve free under the effect of its own weight falls into its closed position, in which it turns on the valve housing connected connecting piece for the Vent line blocked.
  • a known fire shut-off device at the beginning is the type that receives the gate valve, slider housing made of sheet metal like a Cylinder shell domed and has a protruding on all sides, perforated flange.
  • the Main ventilation pipe on which the fire shut-off device To be arranged a connection opening is first cut out. Then the valve body on the Vent line screwed on.
  • the necessary Workload to be performed on site is proportional high.
  • the object of the invention is therefore a fire shut-off device the genus mentioned in such a way that the Inserting into a ventilation system is significantly simplified and is facilitated.
  • the ventilation system becomes the one with the valve housing already firmly connected piece of pipe in the pipe string Ventilation system used. It is not necessary on the Construction site to cut an opening on the pipe string and that Screw the valve housing to the pipe string.
  • the pipe section is a telescopically displaceable Connection pipe piece carries. With that the insertion in simplifies an already finished pipe string and facilitated.
  • the pipe section and the associated valve housing can consist of sheet metal.
  • the gate valve is preferably executed flat and between the flat gate valve and the cylindrically curved pipe wall of the pipe section is a Saddle piece made of insulating material.
  • the flat design of the gate valve simplifies that Manufacture of the gate valve and the associated guide on the valve body.
  • a saddle piece that a balance between the flat gate valve and the curved pipe wall, there is no need to on the back of the pipe facing the pipe Slider housing or the like. to provide.
  • the saddle is preferably made of foamed Ceramic material, which is because of its light weight and its high mechanical strength and simple Manufacturing has proven to be particularly suitable.
  • the pipe section made of insulating material, for example foamed ceramic material and a side Saddle piece on which the flat valve housing is appropriate.
  • the pipe string of insulating material there is a simple construction in the area of the fire barrier.
  • the fire shut-off device shown in FIGS. 1 and 2 is intended for installation in a ventilation system for buildings. It has a valve housing 1 made of sheet metal a connecting piece 2 for one to the ventilation system vent line to be connected. In valve housing 1 a flat gate valve 3 by a (not shown) Trigger device in its raised position shown in FIG. 2 Open position held.
  • the slide housing 1 is on a pipe section 4 above a lateral connection opening 4b attached.
  • a saddle piece 5 Insulating material, for example foamed ceramic material arranged.
  • the saddle piece 5 fills the space between the flat gate valve 3 and the cylindrically curved Pipe wall 4a and forms a guide for the height-adjustable gate valve.
  • a connecting pipe section 6 is telescopic slidable that at its upper edge with an outer circumferential seal 7 is provided.
  • a circumferential seal 8 is provided.
  • the pipe section 4 also carries an outer circumferential seal 9 at its lower end.
  • the fire barrier is spaced between two mutually arranged, concentric pipe sections of a Pipe string used in the ventilation system and through telescopic displacement of the pipe fitting 6 so extended that a tight connection to the two adjacent Pipe pieces of the pipe string is reached.
  • Deviating from the previously described embodiment is that in the fire shut-off device shown in FIG. 3 with the flat slide housing 1 connected pipe section 4 ' Insulating material, for example foamed ceramic material executed.
  • a saddle piece 10 is attached to the side also consists of insulating material and on its flat Outside the slide housing 1 carries.
  • Both embodiments shown have in common that the entire fire shut-off device including the connected one Pipe section 4 or 4 'completely prefabricated becomes. On the construction site, only the pipe section 4 or 4 ' be inserted into the pipe run of the ventilation system.
