摘要:
A temperature monitoring apparatus includes a temperature sensor and a control circuit. The temperature sensor detects a temperature of a piping system, such as a temperature of water in the piping system. The control circuit includes one or more processors and a memory storing instructions that, when executed by the one or more processors, cause the control circuit to determine whether water in the piping system is expected to freeze based on the indication of the temperature, predict whether a valve tripping event is expected to occur based on determining that the water in the piping system is expected to freeze, and in response to predicting that the valve tripping event is expected to occur, provide a prediction that the valve tripping event is expected to occur for remedial action.

A sprinkler assembly include a connection fitting and a fire protection sprinkler. The connection fitting includes a tubular member with a first insertion end and a second insertion end with an internal conduit extending along a longitudinal axis, the tubular member including an exterior surface and an inner surface, the inner surface defining a sealing surface between the first and second insertion ends circumscribed about the longitudinal axis, the inner surface including a gripping portion spaced from the sealing surface. The fire protection sprinkler has a body defining an inlet and an outlet with a passageway between the inlet and the outlet, a deflector spaced from the outlet, the body having an outer encasing surface surrounding the longitudinal axis and including a leading portion and a trailing portion engaged with the gripping portion, having a first retention section and a second retention section.

An embodiment of a fire suppression water intake valve includes a receptacle and a valve assembly. The receptacle is configured to receive a sprinkler head. And the valve assembly is configured to close in response to removing a sprinkler head from the receptacle, and is configured to open in response to installing a sprinkler head in the receptacle. Such a fire suppression water intake valve can allow quick and easy removal and installation of a fire suppression sprinkler head without shutting a water supply to the valve.
摘要:
A gas supply system primarily designed for use with fire sprinkler systems which includes a control system which uses flow demand to automatically determine the mode of operation and switch between providing air and nitrogen. The gas supply system can operate either in standard nitrogen generation mode where nitrogen is supplied to the reservoir tank and/or sprinkler system or in a bypass mode, where sufficient pressure is only obtained by directly supplying air. The gas supply system can provide for improved safety in operation as well as the ability to operate the sprinkler system primarily when filled with nitrogen supervisory gas.

Le dispositif comprend un ensemble (E) apte à être fixé au niveau du plafond du véhicule, et comprenant des moyens (1) et/ou (2) de détection de fumée et/ou d'une élévation anormale de température, et des moyens aptes (3) à brumiser de l'eau sous pression, ledit ensemble (E) étant assujetti à une centrale de commande autonome activable à partir du poste de conduite du véhicule ou à distance, ou automatiquement.
摘要:
A pilot actuator for actuating a dry-pipe type fire suppression system when pressure in a pilot line drops is disclosed. Aspects comprise large pilot sensing area to control fluid sealing area ratio, for higher reliability and reduced actuation slope. Also disclosed are optional acceleration surfaces about the opposing surfaces about the pilot actuator sealing port and utilizing a spring for biasing the pilot operating point pressure allowing higher operating pilot pressure, resulting in faster actuation,. Actuators embodying one or more of the above features are considered. Dry-pipe type firefighting systems utilizing one or more of the aspects described above, and methods for actuation of such firefighting systems are also disclosed.
摘要:
Sectional fire protection systems and methods for the protection of an attic space are provided. A fluid control thermal detection device is located above a ceiling base within a spherical radial distance proximate a peak region of the attic space. An open fluid distribution device is disposed between the roof deck and the ceiling base and connected to the fluid control thermal detection device for receipt of firefighting fluid from the fluid control thermal detection device.
摘要:
Die Erfindung betrifft eine Alarmventilstation einer Feuerlöschanlage (100), insbesondere Sprinkler- oder Sprühwasserlöschanlage, mit einem Feuerlöschanlagenventil (1), mit einem Gehäuse (2, 3), welches eine Fluideintrittskammer (8), eine Fluidaustrittskammer (9) und einen zwischen einem Sperrzustand und einem Freigabezustand hin- und herbewegbaren Schließkörper (4a) aufweist, wobei die Fluideintrittskammer (8) und die Fluidaustrittskammer (9) im Sperrzustand voneinander getrennt sind und im Freigabezustand fluidleitend miteinander kommunizieren. Insbesondere wird vorgeschlagen, dass die Auswerteinheit signalleitend mit einem oder mehreren Aktoren verbunden ist, und dazu eingerichtet ist, den oder die Aktoren mittels der Steuerbefehle zu steuern, wobei die Alarmventilstation vorzugsweise einen oder mehrere Sensoren aufweist und die Auswerteinheit signalleitend mit dem oder den Sensoren verbunden und dazu eingerichtet ist, in Abhängigkeit der ihr vorliegenden Sensordaten den oder die Aktoren zu steuern.
