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.

• A62C 35/62 - Pipe-line systems dry, i.e. empty of extinguishing material when not in use
• A62C 35/68 - Details, e.g. of pipes or valve systems
• F16K 17/30 - Excess-flow valves actuated by the difference of pressure between two places in the flow line acting directly on the cutting-off member operating in one direction only spring-loaded

Abstract

A dry drop to be mounted in a fire protection installation of the type having a network of vacuum sprinklers. The dry drop includes a tubular body, a shutter and a one-way valve. The tubular body defines an inner chamber and has: a first end; a second end; and an orifice located between the first end and the second end. The shutter is movable between: a shutoff position in which it shuts off the first nozzle; and a passage position in which it is cleared from the first nozzle. The one-way valve is intended to be mounted in the orifice to enable the pressurization of the inner chamber by injection of a gas into the inner chamber, the inner pressure holding the shutter in its shutoff position.

• A62C 37/12 - Releasing means, e.g. electrically released heat-sensitive with fusible links

Abstract

The invention relates to a firefighting installation, the installation comprising a valve and including a network that is 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 comprising: - a first duct (A) intended to be coupled to the network under vacuum that comprises the actuator; - a second duct (B) intended to be coupled to a control device that is able to trigger the actuator under the effect of air entering; - a third duct (C) intended to be coupled to a sprinkler device; - a shutter (2) that is movable under the effect of water pressure; - elastically deformable means (3) that are able to keep the shutter in a rest position.

Abstract

The invention relates to a dry drop (3) intended to be mounted in a fire protection installation (1) of the type comprising a network of vacuum sprinklers (4), the dry drop (3) comprising: - a tubular body (33) defining an internal chamber, and having: - a first end (31); - a second end (32); - an orifice located between the first end (31) and the second end (32); - a shutter which is movable between: - a shutting-off position, in which it shuts off the first nozzle; - a passage position, in which it is spaced apart from the first nozzle; characterized in that it comprises a one-way valve (36) intended to be mounted in the orifice to allow the pressurization of the internal chamber by injecting a gas into the internal chamber, the internal pressure maintaining the shutter in its shutting-off position.
