Abstract

Branndetektor omfattende en slange som fylt med gass eller væske og tilordnet an tryWcilde, og hvor slangen er innrettet til å lekke ved forhøyet temperatur, enten ved at slangen smelter eller brenner av. Slangen kan også være porøs med porer som er ugjennomtrengelige ved normal tempertur, men hvor porene aker i sterrelse ved forhayet temperatur og blir gjermomtrengelige, slik at lekkasje oppstår. Slangen er tilordnet en trykkfoler eller en strømningsføler som er innrettet til å reagere når det oppstår lekkasje i slangen, enten ved at trykket synker under en på forhånd bestemt verdi, eller ved at det oppstår en strømning som overstiger en på forhånd bestemt verdi. Slangen kan videre være tilordnet styrte dyser eller ventiler som er innrettet til å åpne på signal, eksempelvis forhøyet trykk i slangen, for derved å kunne tilføre gass eller væske for andre formål enn branndeteksjon. Slike andre formål kan være tilførsel av inert gass eller vann for luftfukting eller vanning av planter.Fire detector comprising a hose filled with gas or liquid and assigned to a pressure valve, and wherein the hose is adapted to leak at elevated temperature, either by melting or burning off the hose. The hose can also be porous with pores that are impermeable at normal temperature, but where the pores rise in size at elevated temperature and become permeable so that leakage occurs. The hose is assigned a pressure sensor or flow sensor which is adapted to react when leakage occurs in the hose, either by the pressure dropping below a predetermined value or by creating a flow exceeding a predetermined value. The hose may further be provided with controlled nozzles or valves which are adapted to open on signal, for example elevated pressure in the hose, thereby being able to supply gas or liquid for purposes other than fire detection. Such other purposes may be the supply of inert gas or water for humidifying or watering plants.
