Definitions

  • the invention relates to fire protection boxes and in particular a fire protection or fire protection enclosure for sensitive devices on risk sites and in particular valves controlled remotely from hydrocarbon tanks.
  • US-A-4 413 683 (HUNE) describes an insulating box in particular for a valve actuator with the characteristics according to the preamble of claim 1, formed of several removable compartments adapted to the various extensions of the protected object and directly supported by this last, being fixed to the support base of the valve actuator.
  • the insulation is dependent on the protected object, which can itself be a source of fire.
  • US-A-4,046,406 (PRESS) describes a device for isolating firewalls from shell-type valves assembled together and fixed to the valve.
  • Such a device does not provide fire isolation independent of the protected object.
  • the invention aims to remedy these drawbacks.
  • a fire protection box for sensitive devices on risk sites, such as the valves of hydrocarbon tanks, comprising an insulating housing, preferably removable, shaped to enclose a sensitive device, for example a hydrocarbon tank valve with its actuation motor, characterized in that said housing is independent of the protected device and comprises a support device and protective end pieces adjoining the housing intended to protect it there are the input and output members (cables and pipes) of the device over a determined length.
  • the support device can be constituted by a simple base of the housing.
  • the housing advantageously comprises an internal tubular rigid frame around which fire-resistant insulating panels are fixed.
  • the housing may include a double insulating wall, namely an internal insulating wall facing the device to be protected and an external wall, capable of being exposed to fire.
  • the frame can be inserted between the space of the two walls.
  • the walls consist of panels of insulating material (based on agglomerated mineral fibers) assembled by means of said frame. Their thickness is adjusted so that the temperature inside the housing is reduced to a maximum value determined after a period of exposure to fire, for example 85 ° C. maximum operating temperature of the valve actuator after one hour of exposure fire according to ISO R 834.
  • This internal frame structure protects it from excessive heating and therefore from possible deformation.
  • the frame can be made of a fire-resistant refractory material and therefore undeformable.
  • the housing is advantageously made up of two parts fitted one on the other to enclose the device, the lower sealed forming a recovery tank for any leaking liquids and comprising a purge or drain element, and the other upper laid by interlocking its lower peripheral edge on the upper edge of the first, and with overlapping of an additional external insulating strip on the closure joint.
  • Inspection hatches are provided, formed within the wall of the housing for access to the control or command members of the protected device.
  • Air vents can be formed on the external wall of the double-walled panels, this in order to allow ventilation of the reinforcement and to improve the resistance over time of the materials.
  • openings and openings of openings are completed with a seal of heat-expandable material sealing them at a certain temperature (180 ° C), level determining a probability of fire.
  • the fire protection box shown in FIG. 1 is a rectangular monobloc rectangular box shaped directly around the object to be protected (hydrocarbon tank valve) not shown.
  • the support frame 1 for the lateral insulating panels 3 of the box is first formed, formed from metallic tubular profiles 5 (visible in FIG. 2) and assembled together to form a rectangular parallelepiped.
  • the insulating panels 3 suitably cut to size are then fixed to the frame by means of simple fixing screws mounted insulated. These panels have the thickness required to maintain the internal thermal insulation at a high level (fire break 1 hour) and resist fire.
  • the temperature inside the box must be less than 85 ° C after 1 hour of exposure to fire according to the above-mentioned standard.
  • the base 7 consists of four tubes 9 covered with insulating material, which have base legs 11 at their lower end and are assembled at the four corners of the box housing formed.
  • the box is then supported independently of the protected object which is not shown and which is normally supported by the piping, in the case of valves. Only emerges from the box pipe elements 13 and electrical cables 15 protected by protective caps 17 fixed on the box and of a sufficient length provided (1 m in general) to protect from possible heat conduction by the cables and pipes themselves same.
  • Inspection hatches 19 are formed on certain panels at the appropriate places for access to the control or object inspection members (handwheel, pressure gauges, etc.).
  • the assembly can be dressed with a corner reinforcement angle 21 made of fire-resistant material (refractory steel).
  • FIG. 2 shows an alternative embodiment of a removable box in two parts according to the invention.
  • the box is also a rectangular parallelepiped, but other shapes can be envisaged, adapted to the shape of the protected object.
  • the box is made up of two complementary rectangular parallelepiped housing parts, upper 23 and lower 25, assembled to one another.
  • the upper housing part 23 is placed on the lower housing part 25.
  • Each of the housing parts has an internal tubular frame 1 (similar to the box in FIG. 1) with a rectangular parallelepiped shape to which two fire-resistant insulating panels 3 are fixed. , joined and to the required thickness.
  • the housing parts are assembled as shown in the figure by fitting the associated reinforcement parts, the pointed end 27 of the reinforcement tubes at the four corners of the upper housing part coming into complementary holes 29 in the reinforcement of the lower housing part, and by interlocking the edges 31 with staircase section of the housing parts.
  • An insulating strip 33 covers the closure joint 35 over the entire periphery of the box.
  • the closing joint is completed with a rod of heat-expandable material 37 which obtains it as soon as the surrounding temperature reaches a certain level, around 180 ° C.
  • the invention is not limited to the embodiments described. Variant embodiments can be considered, as for the geometry of the box, the number of parts composing it, the arrangement of the insulation panels (single, attached or double wall, the possibility of including the reinforcement in the space between the double panels wall, the possibility of adapting ventilation openings on the external panel etc.
