Abstract

A fire suppressing system having at least one suppressant source, at least two control valves in communication with the suppressant source, and at least two distributors, each distributor being in communication with one of the control valves. The control valves are movable between at least three of first, second, third, and fourth positions. In the first position, the first and third apertures are in communication; in the second position, the second and third apertures are in communication; in the third position, the first, second, and third apertures are in communication; in the fourth position, the first and second apertures are in communication. The control valves may be movable to all four positions. Functionally, in the first position, each of the control valves passes suppressant therethrough, but does not pass suppressant to its distributor. In the second position, each of the control valves does not pass suppressant therethrough, but passes suppressant to its distributor. In the third position, each of the control valves passes suppressant therethrough, and passes suppressant to its distributor. In the fourth position, each of the control valves does not pass suppressant therethrough, and does not pass suppressant to its distributor. Depending upon the positions of the control valves, the suppressing system directs suppressant from the suppressant source to any one or more of the distributors. The control valves may be three-way through T directional ball valves. The system may also include further control valves at some or all other T-junctions.

said suppressant comprises one of the group consisting of HFC-227ea, HFC-23, CO₂, and CF₃CF₂C(O)CF(CF₃)₂.

7. The fire suppressing system according to claim 1, further comprising:

at least one further control valve disposed between and in communication with at least one of said control valves and at least one of said suppressant sources;

wherein said at least one further control valve defines first, second, and third apertures therein, and is movable between at least three of first, second, third, and fourth positions, such that

in said first position, said first and third apertures are in communication;

in said second position, said second and third apertures are in communication; and

in said third position, said first, second, and third apertures are in communication;

in said fourth position, said first and second apertures are in communication.

8. The fire suppressing system according to claim 1, further comprising:

at least one further control valve disposed at a T-junction in said system;

wherein said at least one further control valve defines first, second, and third apertures therein, and is movable between at least three of first, second, third, and fourth positions, such that

in said first position, said first and third apertures are in communication;

in said second position, said second and third apertures are in communication; and

in said third position, said first, second, and third apertures are in communication;

in said fourth position, said first and second apertures are in communication.

9. A fire suppressing system, comprising:

at least one suppressant source;

at least one control valve in communication with said at least one suppressant source; and

at least one distributor, each distributor being in communication with one of said control valves;

wherein said at least one control valve are movable between at least three of first, second, third, and fourth positions, such that

in said first position, said at least one control valve passes suppressant therethrough, but does not pass suppressant to said distributor in communication therewith;

in said second position, said at least one control valves does not pass suppressant therethrough, but passes suppressant to said distributor in communication therewith;

in said third position, said at least one control valve passes suppressant therethrough, and passes suppressant to said distributor in communication therewith;

in said fourth position, said at least one control valve does not pass suppressant therethrough, and does not pass suppressant to said distributor in communication therewith;

such that depending upon said positions of said control valves, said suppressing system directs suppressant from said at least one suppressant source to any combination of said distributors.

10. The fire suppressing system according to claim 9, further comprising:

a plurality of suppressant sources;

such that depending upon said positions of said control valves, said suppressing system directs suppressant from any of said suppressant sources to any combination of said distributors.

11. The fire suppressing system according to claim 9, wherein:

at least one of said control valves is movable between all of said first, second, third, and fourth positions.

12. The fire suppressing system according to claim 9, wherein:

said control valves are three-way through T directional ball valves.

13. The fire suppressing system according to claim 9, wherein:

said suppressant is a liquefied compressed gas chemical extinguishing agent.

14. The fire suppressing system according to claim 9, wherein:

said suppressant comprises one of the group consisting of HFC-227ea, HFC-23, CO₂, and CF₃CF₂C(O)CF(CF₃)₂.
