Abstract
A fire suppression system includes a feed port and a channel to couple the feed port to an actuation chamber. A solenoid valve controllably blocks a connection between the feed port and the channel. Pressure from the feed port builds up in the actuation chamber based on the solenoid valve unblocking the connection. A piston is in communication with the actuation chamber. The system also includes an inlet port closed off by a disc. The piston travels through the inlet port and burst the disc based on the pressure in the actuation chamber. An outlet port is coupled to the inlet port.
Claims10
A method of assembling a fire suppression system, the method comprising:
- forming a feed port;
- arranging a channel to couple the feed port to an actuation chamber;
- configuring a solenoid valve to controllably block a connection between the feed port and the channel, wherein pressure from the feed port builds up in the actuation chamber based on the solenoid valve unblocking the connection;
- arranging a piston in communication with the actuation chamber;
- disposing a disc to close off an inlet port, wherein the piston is configured to travel through the inlet port and burst the disc based on the pressure in the actuation chamber;
- and
- coupling an outlet port to the inlet port.
