Closure For Nozzles With Heat Activation And Intelligent Controller For Closures

System for fire-prevention and fire-fighting comprising:

• an intelligent controller,
• at least one fire sensor (14), and
• at least two closures for nozzles with heat activation, each closure comprising:
• a nozzle body (1), wherein the intelligent controller is connected to at least one fire sensor (14);
• and
• an outlet channel (11), wherein a seal (4) is arranged on the nozzle body (1) above the outlet channel (11), which seals off the outlet channel (11), wherein the seal (4) is pressed against the outlet channel (11) by a cover (5) and is held in a closed position, blocking the outlet channel (11), wherein the cover (5) is detachably fastened to the nozzle body (1) and can be actively or passively removed in the event of fire, the cover (5) is arranged in the nozzle body (1) and connected to the nozzle body (1) by at least two fastenings, a first fastening of the at least two fastenings is a releasable arrangement (6) and a second fastening of the at least two fastenings is a connection (7) around which the cover (5) is movable, wherein the releasable arrangement (6) comprises at least one heat sensitive element and is released upon active or passive activation of at least one of the heat-sensitive elements, wherein said at least one fire sensor (14) are located in the nozzle body (1) or in the cover (5),
• characterized in that the intelligent controller receives an external signal from a fire sensor (14) located on a first of the at least two closures or an external fire alarm or instruction and heats the at least one heat sensitive element of a second of the at least two closures.

A closure for nozzles with heat activation, comprising:

• a nozzle body (1);
• and
• an outlet channel (11), wherein a seal (4) is arranged on the nozzle body (1) above the outlet channel (11), which seals off the outlet channel (11), wherein the seal (4) is pressed against the outlet channel (11) by a cover (5) and is held in a closed position, blocking the outlet channel, wherein the
• cover (5) is detachably fastened to the nozzle body (1) and can be actively or passively removed in the event of fire, the cover
• (5) is arranged in the nozzle body (1) and connected to the nozzle body (1) by at least two fastenings, a first fastening of the at least two fastenings is a releasable
• arrangement (6) and a second fastening of the at least two fastenings is a connection (7) around which the cover (5) is movable, wherein the releasable arrangement (6) comprises at least one heat-sensitive element and is released upon active or passive activation of at least one of the heat-sensitive elements, wherein the heat-sensitive element is arranged inside the nozzle body (1) and either located inside the cover (5) or on the inside of the cover (5), facing the outlet channel (11) and active heating of the heat-sensitive element is controlled by an intelligent controller, which communicates with the at least one fire sensor (14), both intelligent controller and fire sensor (14) are arranged in the nozzle body.
