Definitions
- Fire-fighting installation including a network of vacuum sprinklers, which can be triggered by an actuator comprising a piston and being controlled by a master actuator.
- 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 fire-fighting installations are classified in three categories, namely:
- sprinklers are networked so as to be regularly distributed on the site to be protected.
- sprinklers include:
- a fixing connection for connecting the sprinkler to a pipe, this fixing fitting having a nozzle for the passage of water to release to extinguish the fire;
- a sealing cap of the nozzle held in the closed position by the fuse.
- 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 sprinklers or sprinklers whose 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.
- An actuator member is movable between two positions, namely: a position prohibiting the communication of the two conduits, which corresponds to a vacuum hold of the sprinkler network;
- the actuator of the prior art described by patent document FR-2,724,323 comprises a cylinder body C having:
- a water flow conduit C3 communicating with the circuit triggering the impoundment of the sprinkler system.
- 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 of 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 in Figure 1) , which links the conduits C2 and C3, leading to the triggering of the installation.
- the warhead can leave, even stealthily, its closed position, which may be sufficient for the spring R to exert a traction greater than 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 invention particularly aims to overcome these disadvantages of the prior art.
- the invention aims to provide a fire-fighting installation, of the type implementing a vacuum network of sprinklers, which is not or only subject to unexpected trips.
- 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 pipe and a water outlet pipe that can be placed in communication, an outlet pipe the actuator being able to authorize / prohibit the placing in communication of the water inlet duct with the water supply duct such that the prohibition of the communication of the two ducts maintains the network of sprinklers under empty while putting the two pipes in communication triggers the impounding of the sprinkler network.
- the triggering device comprising at least one actuator comprising a body into which a water inlet pipe and a water outlet pipe that can be placed in communication, an outlet pipe the actuator being able to authorize / prohibit the placing in communication of the water inlet duct with the water supply duct such that the prohibition of the communication of the two ducts maintains the network of sprinklers under empty while putting the two pipes in communication triggers the impounding of the sprinkler

- 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 furthermore has a third duct 44, capable of being placed in communication with the water inlet duct 41 when the piston 43 is in the trigger position, such as that illustrated in Figure 5.
- This third conduit 44 communicates with a hydraulic alarm circuit 24 ( Figure 2).

- the lever 6 is pivotally mounted about an axis 62 carried by the body 40 of the shutter.
- the position of the axis 62 is significantly closer to the end of the yoke lever side than that of the side of the locking means, so as to increase as much as possible the amplitude of the movement of the lever to the end lever on the side of the locking means with respect to the yoke side.
- the locking means 60 takes the form of a spacer 63 pivotally mounted at the end of the lever 6 about an axis 64.
- the locking means 60 can pivot about its axis 64, thus allowing the corresponding end of the lever to be displaced circularly. , and to disengage from the locking position.
- the locking spacer may take the form of a head having an inverted U-shaped recess in which the outer portion 432 of the piston is housed in the locking position.
- the operation of the triggering device is as follows.
- the shutter constituted by the ballast 53 falls towards the disk 502, by driving the membrane 51, and by moving, via the axis 52, the stirrup 54 towards the low.
- the lug 540 of the bracket 54 present in the oblong slot 61 then pushes the corresponding end of the lever downwards, causing the lever 6 to pivot about its axis 62 and, consequently, the rise of the spacer 63 locking up, simultaneously with the tilting thereof around its axis 64.
- the lever acts as a transmission member between the yoke and the locking means in position of the piston of the actuator.
- the stroke of the piston is provided in such a way that the duct 41 communicates on the one hand with the conduit 42 for the flow of water and, on the other hand, with the third conduit 44.
