Abstract
A firefighting installation including a valve and a network kept under vacuum in a standby position and flooded with water by an actuator if the installation is triggered in the event of a fire. The valve includes: a first conduit to be coupled with the vacuum network which includes the actuator; a second conduit to be coupled with a control device adapted to trigger the actuator by the effect of an air intake; a third conduit to be coupled to a sprayer; a shutter movable by the effect of a water pressure; and an elastically-deformable element adapted to hold the shutter in a rest position.
Claims10
A firefighting installation comprising:
- a vacuum network of sprinklers kept under vacuum in a standby position and flooded with water by an actuator if the installation is triggered in an event of a fire;
- and
- at least one valve, comprising:
- a first conduit coupled with the vacuum network which comprises the actuator;
- a second conduit opposite the first conduit and coupled with a control device adapted to trigger the actuator by an effect of an air intake at a level of the control device;
- a third conduit coupled to a sprinkler of the network of sprinklers and communicating with the first conduit and the second conduit;
- a shutter movable by an effect of a water pressure;
- and
- an elastically-deformable element adapted to hold the shutter in a rest position;
- wherein the shutter is movable between at least:
- the rest position in which the first conduit, the second conduit and the third conduit communicate with one another;
- and
- a closure position in which the second conduit is shut off and in which the first conduit and the third conduit communicate with one another,
- wherein, in the rest position of the shutter, the valve has at least:
- a first passage between the first conduit and the third conduit;
- a second passage between the second conduit and the third conduit;
- the first passage and the second passage being formed between the shutter and a central body of the valve.
A valve configured for use in a firefighting installation including a network of sprinklers kept under vacuum in a standby position and flooded with water by an actuator if the installation is triggered in an event of a fire, the valve comprising:
- a first conduit;
- a second conduit opposite the first conduit;
- a third conduit communicating with the first conduit and the second conduit;
- a shutter movable by an effect of a water pressure;
- an elastically-deformable element adapted to hold the shutter in a rest position;
- the shutter being movable between at least:
- the rest position in which the first conduit, the second conduit and the third conduit communicate with one another;
- and
- a closure position in which the second conduit is shut off and in which the first conduit and the third conduit communicate with one another;
- wherein, in the rest position of the shutter, the valve has at least:
- a first passage between the first conduit and the third conduit;
- a second passage between the second conduit and the third conduit;
- the first passage and the second passage being formed between the shutter and a central body of the valve.
