METHOD AND APPARATUS FOR DISTRIBUTING FIRE SUPPRESSANT

摘要

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 disk valves, and/or three-way through T directional ball valves. The system may also include further control valves at some or all other T -junctions.
