摘要： A mechanical time delay apparatus for creating a time delay between a pneumatic inlet for connection to a source of pressurized gas and a pneumatic outlet includes a primary pneumatic flow path from the inlet to the outlet. A movable gate is associated with the primary pneumatic flow path and is movable between an open position and a closed position. The gate is urged by a biasing force to the closed position. In the closed position, the gate is disposed to block a flow of gas through the primary pneumatic flow path. In the open position, the gate permits such flow. The time delay apparatus further includes an accumulation chamber in communication with the gate for a gas pressure within the accumulation chamber to urge the gate against the biasing force to the open position when the gas pressure exceeds a threshold pressure. A secondary pneumatic flow path extends the inlet to the accumulation chamber. An adjustment mechanism is provided for adjusting an internal volume of the accumulation chamber to thereby adjust an amount of time required for a gas admitted to the accumulation chamber to exceed the threshold pressure. The apparatus may be used in a fire suppression system to impart a time delay between detection of a fire hazard and release of a fire suppressant.

摘要： A low-pressure actuator (1) for use in a dry, low-pressure, pressurized-gas, fire control and suppression sprinkler system for delivering an extinguishing liquid to a fire is disclosed. The device is actuated by a rapid fall in the system gas pressure, whereupon it allows liquid to flow through to a sprinkler check valve, which, in turn, is actuated and provides liquid flow for distribution through a piping system to a plurality of interconnected sprinklers. One embodiment of the device includes a first diaphragm (18) which acts as a gas-liquid barrier, and a second diaphragm (23), which acts as a liquid flow barrier. When gas pressure in the sprinkler system drops below a predetermined set point, pressure equilibrium on the first diaphragm is upset causing the first diaphragm to move and allow a priming flow of liquid to the liquid outlet through a liquid by-pass (13), which is otherwise sealed. This also simultaneously causes the second diaphragm to move and allow a greater flow of liquid, which provides the main extinguishing liquid, to the liquid outlet. Embodiments of a low-pressure actuator with a pneumatic/electric double interlock (51, 52, 53, 54) system, which requires that two separate events, such as discharging air pressure from the sprinkler system, and an electrical detection, must occur in order for the sprinkler control valve to activate and allow water into the sprinkler system, wherein the low-pressure actuator further includes an electrical detector and a solenoid coil assembly, are also disclosed.

摘要： The invention relates to an installation comprising a high pressure drive unit for extinguishing liquid. When a fire has broken out in a fire section (A), a low pressure liquid source is connected (9, 10) to the respective fire section and the pressure of this liquid is utilized both for establishing a connection (11, 12) through a pilot valve means from the respective fire section to the outgoing line (5) of the high pressure drive unit, before this drive unit is activated, and for closing the connections from other fire sections to said outgoing line (5). The invention makes it possible to use cheap low pressure valves (9) in the pilot valve means.
