Abstract
A valve and valve arrangement for a fire suppression system includes a remotely controlled valve such as a solenoid valve which is electrically controlled to provide a preselected flow through the remotely controlled valve corresponding to the flow through a single sprinkler head.
Claims18
A valve arrangement for use in a fire suppression sprinkler system, said valve arrangement comprising:
- valve means for controlling the flow of a fluid, said valve means comprising an inlet and first and second outlets, said valve means comprising a first configuration selectively permitting flow from the inlet to the second outlet and preventing flow from the inlet to the first outlet, and a second configuration selectively permitting flow from the inlet to the first outlet and preventing flow from the inlet to the second outlet;
- means for restricting the flow through the first outlet of the valve means to a preselected rate corresponding to the flow through a single fire suppression sprinkler;
- means for remotely controlling said valve means between said first and second configurations;
- wherein said valve means comprises a solenoid valve.

- means for restricting the flow through the first outlet of the valve means to a preselected rate corresponding to the flow through a single fire suppression sprinkler at least while the valve means is in the second configuration;
- and
- means for remotely controlling said valve means between said first and second configurations;
- wherein said valve means comprises a solenoid valve.
2 more elements
A valve arrangement for remotely and manually testing a fire suppression sprinkler system, said valve arrangement comprising:
- conduit means for supplying a fire suppression fluid to a plurality of sprinklers;
- means for sensing a flow of said fire suppression fluid in said conduit means;
- supply valve means for controlling a flow of fluid through said conduit means;
- first testing valve means for testing the means for sensing a flow of said fire suppression fluid in said conduit means, said first testing valve means comprising an inlet, a first outlet and a second outlet, said first testing valve means comprising a first configuration selectively preventing flow from the inlet to the second outlet and a second configuration selectively permitting flow from the inlet to the second outlet at a preselected rate corresponding to the flow through a single fire suppression sprinkler;
- and
- second testing valve means for testing the means for sensing a flow of said fire suppression fluid in said conduit means, said second testing valve means comprising an inlet, a first outlet and a second outlet, said second testing valve means comprising a first configuration selectively allowing flow from the inlet to the second outlet and a second configuration selectively permitting flow from the inlet to the first outlet at a preselected rate corresponding to the flow through a single fire suppression sprinkler;
- said inlet of said second valve means being in communication with the conduit means downstream of the first testing valve means.
