Definitions

  • the present invention relates to a device for flameless pressure relief with at least one inner layer of a textile fabric or a textile body of metal filaments.
  • the resulting in a building or a vessel flames are extremely efficiently cooled in the layers of textile fabrics of metal filaments and so stifled. Also, a pressure prevailing in the building or the vessel overpressure is reduced by the device. The flames do not escape from the device.
  • Both the Q-box and the Q-tube define a space into which the flames may enter and which is bounded by the at least one inner layer. By choosing the size of the room, the area over which the pressure relief can take place is specified. Both the Q-box and the Q-tube have an outer basket or housing which holds the inner layers of metallic filament fabrics together. For flameless pressure relief, the outer basket or the outer housing does not contribute. Pursuit of Outdoor basket or the outer housing reduce even effective for the pressure relief surface.
  • the invention was based on the problem of making a device for flameless pressure relief simpler and to increase the effective area for the pressure relief.
  • This object is achieved in that is provided as an outer layer of a fabric formed from a fabric or a textile body shell, wherein in the space enclosed by the shell, the inner layers are received and the shell and the inner layers an inlet opening for the Entry of gases and / or flames in the space enclosed by the shell, the inner layers.
  • the inlet opening can be connected to a closed with a rupture disc opening of the container to be secured.
  • the sheath and / or the at least one inner layer is self-supporting, that is, the sheath and / or the at least one inner layer give the outer and / or inner layers a stiffness, so that the shape of the enclosed by the at least one inner layer Space is given.
  • a support frame between the at least one inner layer and the shell may be provided, which gives the shell and / or the at least one inner layer an additional rigidity.
  • the support frame may have an inlet for the entry of gases, dust and / or flames in the enclosed space of the shell, the support frame and the inner layers.
  • the shell, the at least one inner layer and / or the support frame can be so flexible that the outer shape can be adapted to the space conditions at the installation site, without having to replace the device. It is also possible that the components mentioned are so flexible that they can be adapted to different openings of containers to be protected. For example, the device can be adapted to round or square openings.
  • An outer basket or outer housing is not necessary in a device according to the invention for flameless pressure relief.
  • the function is taken over by a shell, which is made like the inner layers of a textile fabric or a textile body of metal threads or metal wires.
  • an outer basket or an outer housing may be provided.
  • the shell is to the shape of the arrangement of the support frame and / or the inner Adjusted layers and envelops them.
  • the shell is as close as possible to the outermost inner layer. Webs of textile fabrics can be sewn into a textile body structure.
  • the support frame is provided for the fact that the inner layers of textile fabrics or textile body structures do not coincide in a non-use state and the inner layers sufficient stability, so that the space accessible via the inlet openings and necessary for the pressure relief space is maintained ,
  • the outer shell ensures that the layers do not detach in the non-use state as well as in use and fly through the area.
  • the device according to the invention can be provided exactly a shell.
  • the device according to the invention it is also possible for the device according to the invention to have two or more sheaths, the sheaths, like onion shells, enveloping one another and the inner layers and the support frame.
  • the sheath can be composed of several webs of textile fabrics, in particular sewn together. But it is also possible that the shell already in the production, ie when weaving, knitting or working receives its shape and is a textile body structure.
  • the apparatus may comprise a frame defining an inlet opening of the device for the entry of gases, dust and / or flames in the enclosed space of the shell, the inner layers and the support frame.
  • the support frame can be connected to the frame. Then the frame can also limit the inlet opening of the support frame.
  • the frame may define a round or polygonal, in particular square, hexagonal or octagonal entry opening.
  • the inner layers and / or the shell are connected to the frame.
  • the frame can then also limit the inlet openings of the inner layers and / or the shell.
  • the frame may have a collar suitable and arranged for connection to an object to be secured.
  • a collar suitable and arranged for connection to an object to be secured.
  • holes for screwing the frame - and thus the entire device - be provided at a relief opening of a building or vessel to be protected.
  • the shell can at least partially have the shape of a spherical segment. It is also possible that the sheath of a device according to the invention is trough-shaped, spherical or oval shaped.
  • the metal threads and / or the metal mesh from which the textile fabrics or textile body structures are made can be stainless steel threads. However, it is within the scope of the invention to use filaments of other metals or alloys or non-metallic materials.
  • the textile fabrics or the textile body structures of different layers can also be made of different metal threads. It is even possible that between the layers of the fabrics of metal filaments layers are provided, which are made of a plastic or other non-metallic materials. This can also be a textile fabric or a textile body structure. This can then be made of plastic threads or synthetic fibers.
  • the shell of a device according to the invention can be made of a textile fabric or a textile body structure made of plastic threads.
  • At least one of the textile fabrics or the textile body structures may be a woven fabric, a knitted fabric, a knitted fabric, a braid, a nonwoven fabric or a felt.
  • the inlet opening of a device according to the invention is closed by means of a bursting disc, which can be attached to the frame.
  • the first device according to the invention has a frame 1 which encloses a rectangular inlet opening.
  • the frame 1 has a collar 10 in which holes 11 are provided, via which the frame 1 and thus the entire first device can be attached to a housing or building to be protected.
  • a support frame 2 is attached on the frame 1, a support frame 2 is attached.
  • the support frame 2 is bent from metal rods 20, which are connected at intersections 21 with each other.
  • the rods are bent in a circular arc with one exception.
  • a pole is straight. All rods are connected to this straight rod.
  • a shell 4 as an outer layer envelops the inner layers and the support frame 2 and thus holds the inner layers in a solid composite with the support frame second
  • the second device according to the invention according to the FIGS. 8 to 10 corresponds to the basic structure of the first device according to the invention.
  • This shape is the shape of a sphere section. This results in a circular frame 1, which in the case of second device has no collar.
  • inner layers 3 are applied from textile fabrics of metal filaments, which are enveloped by a shell 4 in the form of a spherical segment as an outer layer.
  • the space lying within the support frame 3 is immediately available for pressure relief. By the inner layers and the shell extinguishing flames is achieved if flames hit the interior of the devices.
