Dry accelerator for sprinkler system |
摘要 |
An accelerator for venting a pressurized gas source to the ambient is disclosed. The accelerator includes a first gas compartment connected to the pressurized gas source. A second gas compartment is connected to the first gas compartment through a one-way valve allowing gas to pass from the first gas compartment to the second gas compartment. A restrictor orifice allows gas to pass between the first and the second gas compartments at a predetermined rate. A valve member in the first gas compartment is normally in the closed position and moves to the open position in response to a pressure drop of the pressurized gas source causing a pressure differential between the first and second gas compartments, thereby venting the pressurized gas source to the ambient through the valve member in the first gas compartment.
