COMPACT MINIATURE FIRE-EXTINGUISHING AND/OR FIRE-PROTECTION DEVICE

摘要

A fire-extinguishing or fire-protection device formed from a pressure vessel filled with a pressurized extinguishing medium. The device has an exit opening closed by a closure element which can be perforated by a perforation element. The pressurized extinguishing medium is held back in the pressure vessel from a passively thermally controlled trigger valve attached directly to the exit opening. The valve has a perforation element and a thermal triggering element. The perforation element is prestressed in a triggering position and is retained by the thermal triggering element in a standby position. When the triggering element is triggered as a result of a predetermined temperature being reached, the perforation element is released moving the triggering element to the triggering position in which it perforates the closure element. A thermal trigger valve suitable for use in the fire-extinguishing or fire-protection device is disclosed.

1. A fire extinguishing or fire protection device, formed from
a pressure container filled with a pressurized extinguishing medium and having an exit opening that is sealed with a closure element perforable by means of a perforation element; wherein the pressurized extinguishing medium is retained in the pressure container; and a passively thermally controlled trigger valve seated directly on the exit opening and having a perforation element and a thermal triggering element; wherein the perforation element is pretensioned in the direction of a triggering position and held by the thermal triggering element in a standby position that is different from the triggering position and wherein when triggered by a predetermined triggering temperature being reached, the thermal triggering element releases the perforation element; wherein the perforation element driven by the pretensioning to which it is subjected in the standby position moves into the triggering position and perforates the closure element.
