摘要:
A dry sprinkler assembly capable of providing fire suppression protection, including early suppression fast response protection and storage protection of a commodity having a nominal storage height of at least 20 feet beneath a ceiling of with a maximum nominal 40 foot ceiling height. The dry sprinkler assembly includes an internal passageway and an outlet defining a nominal K-factor of at least 16.8 GPM/PSI1'2. Embodiments of the sprinkler assembly include a deflector having a plurality of tines radially disposed about a central portion to define slots therebetween. Embodiments of the deflector define a non-planar deflecting member and a member with a non-circular perimeter. Installation of the sprinkler assembly provides for a insulation sealing assembly having a insulation ring, planar insert member and a surrounding housing.

Die Erfindung betrifft ein Verfahrenund eine Vorrichtungzur Brandverhütung und Brandlöschung in umschlossenen Räumen (10), deren Raumluftatmosphäre einen vorgebbaren Temperaturwert nicht überschreiten darf. Um zu erreichen, dass die von einer Klimaanlage bereitzustellende Kühlkapazität selbst dann nicht erhöht werden muss, wenn in die Raumluftatmosphäre kontinuierlich oder regelmäßig Inertgas nachgeführt wird, um im Inneren des umschlossenen Raumes ein bestimmtes Inertisierungsniveau einzustellen bzw. zu halten, ist erfindungsgemäß eine Anlage zum geregelten Einleiten von Inertgas in die Raumluftatmosphäre des umschlossenen Raumes (10) vorgesehen. Die Anlage weist einen Behälter (1) zum Bereitstellen und Lagern des Inertgases in verflüssigter Form und einen mit dem Behälter (1) verbundenen Verdampfer (16) zum Verdampfen von zumindest einem Teil des in dem Behälter (1) bereitgestellten Inertgases und zum Einleiten des verdampften Inertgases in die Raumluftatmosphäre des umschlossenen Raumes (10)auf. DerVerdampfer (16) ist dabei ausgelegt, die zum Verdampfen des flüssigen Inertgases erforderliche Wärmeenergie der Raumluftatmosphäre des umschlossenen Raumes (10) direkt oder indirektzu entnehmen.

A dry pipe sprinkler assembly is provided including a sprinkler body having a thermally responsive trigger mounted thereto. A housing, including an inlet end and an outlet end is provided with the outlet end being connected to the sprinkler body. A seal member is disposed at the inlet end of the housing, and a load mechanism extends between the thermally responsive element and the seal member. The load mechanism may include a support portion, a passage tube portion, and an outlet orifice portion slidably received within the housing and movable within the housing upon activation of the thermally responsive trigger to allow the seal member to be dislodged from the inlet end of the housing to allow suppressant fluid to flow therethrough. The dry pipe sprinkler assembly allows the use of different outlet orifice members to provide dry pipe sprinkler assemblies having different K factors while utilizing common components for the remaining dry pipe sprinkler assembly.

A thermal trigger assembly for remote mechanical actuation of another fire protection system component includes an activation component having a base and a movable member. A bias member biases the movable member from a preactivation to an activated position with respect to the base. A thermally responsive element retains the movable member in the preactivation position until a predetermined thermodynamic condition is reached, when the thermally responsive element loses structural integrity. A flexible connector includes a flexible hollow outer cable housing with one end configured to be stationarily (preferably fixedly) connected with the base. A flexible cable is inside the outer cable housing for sliding movement therein and has one end configured to be stationarily (preferably fixedly) connected with the movable member. The flexible cable is moved with respect to the outer cable housing by movement of the movable member upon loss of structural integrity by the thermally responsive element.

The invention relates to a power source for supplying water-based liquid to a system (1, 2) through a pipe system (4) which is filled with antifreeze so that the pipe system has a stand-by pressure, wherein a container (5) for the water-based liquid, an additional container (9) which is filled with antifreeze and means (6) for feeding the water-based liquid from the container (5) into the pipe system in liquid phase if the pressure in the pipe system drops below the stand-by pressure by a first pressure value giving momentarily rise to a first pressure level in the pipe system, are associated with the pipe system. To enable economical and automatic supply of water-based liquid to a system without the risk of the liquid freezing, the means for feeding water-based liquid comprises as part of the power source a pump unit (6) comprising a pump (7) and a power source (8) and that the power source comprises an additional pump unit (10) comprising a pump (11) and a power source (12), the additional pump unit being arranged to maintain the stand-by pressure and to supply for this purpose antifreeze from the additional container (9) to the pipe system (4) if the pressure in the pipe system drops below the stand-by pressure by a second pressure value giving momentarily rise to a second pressure level in the pipe system, the second pressure level being bigger than the first pressure level.
