Definitions

  • the field of the invention is that of the design and manufacture of fire fighting equipment and installations. More specifically, the invention relates to a trigger device designed for firefighting installations called "vacuum”.
  • the role of an automatic fire extinguishing system using sprinklers is to detect, as soon as possible, a fire and then automatically trigger the extinguishing system, at least locally, while emitting an alarm.
  • the purpose of the installation is to contain as much as possible the fire, before the arrival of the firefighters who then take over the installation to extinguish the fire.
  • the fuse is calibrated to burst when a certain temperature is exceeded, thus releasing the nozzle from its sealing cap.
  • underwater systems are not suitable for sites with frost risks. Indeed, in case of frost, the water can not flow.
  • the gel can cause damage to the piping of the installation (deformation or burst pipes).
  • the installation is then put out of water.
  • the site to be protected is heated to avoid any risk of frost.
  • energy consumption, and therefore the heating bill can be considerable, even prohibitive.
  • Another way to fight against freezing is to add an antifreeze to the water of the installation, such as glycol, which is a toxic and carcinogenic product.
  • the water can in some cases take up to 60 seconds to reach the sprinkler whose fuse is burst, which is certainly in line with the standard in force but may be too long vis-à-vis vis of some fire starts.
  • vacuum systems have been designed.
  • a vacuum is created in the pipes extending between a general valve and the set of sprinklers.
  • all the pipes separating the valve from the sprinklers are under vacuum.
  • vacuum is an active energy that serves as a functional source for sprinkler monitoring. Indeed, if a fuse of one of the sprinklers bursts, the atmospheric pressure wins the entire installation, which causes the change of state of an actuator which, in turn, opens the general valve of arrival of water. It follows that the water invades quickly and without obstacles the entire installation to the sprinklers, the water flowing through the sprinkler (s) where the fuse has burst. The still active vacuum in the networks quickly attracts the extinguishing water to the sprinklers whose fuse has burst.
  • the tripping time of the actuator is very short, since when a fuse bursts, the "vacuum" installation immediately generates a phenomenon of suction of the air outside the installation. It should be noted that this suction can be beneficial, the suction effect on the fire focus to reduce the intensity of it.
  • the water inlet time of the sprinkler with the fuse blown is less than 60 seconds.
  • the trigger that is to say the watering of the sprinkler network, is obtained using a device comprising an actuator.
  • Such an actuator comprises a body in which open a water inlet duct and a water outlet duct capable of being placed in communication with each other.
  • a spring R is mounted in the body C of the actuator, this spring R being mounted in tension and coupled to the ogive O so that the spring tends to pull the ogive out of its closed position .
  • the sprinkler system when the sprinkler system is under vacuum, it sucks the warhead into a closed position of the conduit C1, with a force greater than that calibrated in a predetermined manner of the spring R.
  • the sprinkler system when the sprinkler system is set the atmospheric pressure (by bursting a fuse from at least one of the sprinklers of the installation), the suction force of the warhead is removed and the spring pulls the warhead (to the left on the figure 1 ), which links the conduits C2 and C3, leading to the triggering of the installation.
  • the warhead can leave, even stealthily, its position. shutter, which may be sufficient for the spring R to exert traction superior to the suction power initially present in the conduit C1.
  • the actuator then takes its position authorizing the triggering of the impoundment of the installation.
  • the purpose of the invention is to propose a fire-fighting installation, of the type implementing a vacuum network of sprinklers, which is not or only slightly subject to unexpected tripping.
  • the invention also aims to provide such a facility to achieve its commissioning quickly and convenient way.
  • a fire-fighting installation including a network of vacuum sprinklers, the installation integrating a device for triggering the setting water of the sprinkler network, the triggering device comprising at least one actuator comprising a body into which a water inlet duct and a water outlet pipe that can be placed in communication, an organ of the actuator being able to authorize / prohibit the placing in communication of the water intake pipe with the water supply pipe so that the prohibition of the communication of the two conduits maintains the network of vacuum sprinklers while the communication of the two pipes triggers the impoundment of the sprinkler network.
  • the setting of the triggering device is done automatically by the vacuum of the sprinkler network.
  • said membrane is advantageously mounted in an enclosure, so as to form a sealed deformable partition between two passages opposite to each other formed in the enclosure, namely a primary conduit communicating with the sprinkler system and a secondary passage through which an axis coupled to the yoke can slide, said axis being secured to the membrane and a ballast.
  • the enclosure is then advantageously delimited by a bell and a closure disk, the membrane being clamped between the bell and the disk.
  • said axis is also coupled to a spring for pushing the membrane towards the second position.
  • said spring is mounted in compression bearing on a wheel adjustable in position on said axis.
  • the locking means comprises a tilting locking spacer mounted at one end of a pivoting lever connected by the other of its ends to the yoke.
  • the lever is advantageously pivotally mounted on the actuator.
  • the actuator comprises a piston movable in a cavity of the body, and has an outer portion extending out of said cavity and being provided with a ring on which the locking means is intended to act.
  • a spring is advantageously mounted in the cavity of the body of the actuator so as to push the piston out of the cavity when the stirrup is in said second position.
  • the spring has a first end cooperating with the piston and a second end, opposite to the first, bearing on a plate of the body, said plate having a central finger on which the spring is threaded.
  • the actuator comprises a piston movable in a cavity of the body and the water inlet conduit communicates with a pipe which controls the general valve for flooding the sprinkler system, the valve general being closed when the pilot line is in pressurized water and open when the pilot line is depressurized, the piston being movable between a closed position and the inlet conduit maintaining the pressure in the pilot line and a release position authorizing the communication of the arrival conduit with the departure conduit.
  • the starting conduit communicates with a water draining circuit.
  • the actuator comprises a piston movable in a cavity of the body, the body having a first end through which the piston can move, and a second end opposite to the first, the starting conduit being formed in the second end or between the starting duct and the second end, the starting duct communicating with a circuit at atmospheric pressure.
  • Such a starting pipe positioned in this way and being at atmospheric pressure, tends to promote the movement of the piston, in particular at the start of its change of state to go to the trigger position.
  • the actuator comprises a piston movable in a body cavity, a third conduit being formed in the body and being capable of being placed in communication with the arrival conduit in said second position. of the stirrup, the third conduit communicating with a hydraulic alarm circuit.
  • the actuator according to the invention can trigger simultaneously, or almost, the impoundment of the sprinkler system and the activation of the hydraulic alarm.
  • the commissioning of such an installation provides for the evacuation of the sprinkler network S, the vacuum thus also being present in the line 21 leading to the trigger device 2.
  • the triggering device 2 keeps the control chamber of the general valve 3 under water pressure, which keeps it in a closed position.
  • the sprinkler network S starts at atmospheric pressure, which also propagates at the line 21, which switches the state of the trigger device 2, which then allows , as will be described in more detail below, the pressure drop in the control chamber of the general valve 3, which will cause the opening of the latter and the impoundment of the sprinkler network S.
  • an actuator intended to be integrated in an installation according to the invention comprises a body 40, in the form of a cylinder, having a central cavity 400, and into which a conduit 41 for supplying water and a conduit 42 of water flow, the two conduits being capable of being put in communication with each other.
  • the actuator also incorporates a piston 43, constituting an actuator member adapted to allow / prohibit the placing in communication of the conduit 41 with the conduit 42.
  • the water supply pipe communicates with a pilot line 22 connected to the control chamber of the general valve 3 ( figure 2 ), the latter being closed when the pilot line 22 is in pressurized water and open when the pilot line is depressurized.
  • the conduit 42 of water flow communicates with a water drain circuit 23, at atmospheric pressure.
  • the piston 43 of the actuator is movable between a closed position of the duct 41, which maintains the pressure in the pilot line 22 (resulting in a closed position of the general valve 3), and a position of release allowing the communication of the conduit 41 of water inlet with the conduit 42 of water flow, which causes the pressure in the control chamber of the general valve and causes the opening thereof, and thus the impoundment of the sprinkler system.
  • the body 40 of the actuator further has a third conduit 44, capable of being placed in communication with the conduit 41 of water inlet when the piston 43 is in the release position, such as that illustrated by the figure 5 .
  • This third conduit 44 communicates with a hydraulic alarm circuit 24 ( figure 2 ).
  • the piston 43 comprises a closing portion 430, which is extended by an axis 431, an outer portion 432 extends out of the body 40 of the actuator.
  • This portion 432 has at its end a ball 433 gripping.
  • the portion 432 has, outside the body of the actuator, a ring 434, bearing against the body of the actuator in the waiting position thereof.
