摘要:
Improvements to a portable fire extinguisher are disclosed. The improvements allow for frequent and simplified inspection and maintenance of a fire extinguisher with minimal training and without need for custom equipment. The improvements include an anti-bridging mechanism that can be articulated from the exterior of the chamber to fluff, mix or stir the powder within the chamber to keep it in a liquefied state. Additional improvements include a larger opening to more quickly fill and inspect the powder within the chamber. Another improvement includes the use of a CO2 cartridge located external to the chamber to allow easier servicing or replacement of just the CO2 cartridge as well as the ability to maintain the chamber in an un-pressurized condition, allows for non-HASMAT shipping. These features will extend the service intervals while maintaining the fire extinguisher in a ready condition.

A valve mechanism 100 is herein described that utilises a frangible plug 10. The valve mechanism comprises a valve body 50 having an inlet port 52 and an outlet port 54 and a passageway 56 extending therebetween. The valve mechanism 100 comprises a frangible plug 10 that is held within the valve body 50 to block the passageway 56 when the plug is intact. The plug comprises a predefined fracture plane and is configured to fracture across the predefined fracture plate 90 upon application of an impact force.

According to one aspect, a fire extinguisher (102) includes a fire extinguisher reservoir (106) and a fire extinguisher outlet burst disc (108) that forms a discharge barrier between the fire extinguisher reservoir (106) and a discharge head (104) to retain a pressurized fire extinguishing agent (212) at an internal fire extinguisher pressure (214) within the fire extinguisher reservoir (106). A cutter (204) is detained within the fire extinguisher (102) proximate the fire extinguisher outlet burst disc (108). An interior container (215) within the fire extinguisher reservoir (106) has a container pressure (221) and is sealed with a container burst disc (219). An activation device (220) having a piercing member (222) is operable to pierce the container burst disc (219) and diffuse the container pressure (221) to create a pressure differential relative to the internal fire extinguisher pressure (214) at the cutter (204), thereby driving the cutter through the fire extinguisher outlet burst disc (108) to release the pressurized fire extinguishing agent (212) through the discharge head (104).

PROBLEM TO BE SOLVED The present invention provides a jetting apparatus for fire extinguishing gas. The jetting apparatus for fire extinguishing gas is suitable for a handy fire extinguisher, for example, in a house, an office and a vehicle; easily breaks a sealing plate of a small gas cylinder charged therein; temporarily prevents gushed fire extinguishing gas from outflowing and being wasted by a valve; attempts to efficiently use the fire extinguishing gas and to effectively extinguish a fire; jets the fire extinguishing gas to the origin of a fire surely and properly in fire fighting; realizes that a fire is extinguished effectively, surely and early; and informs us where the fire extinguisher is when a fire occurs so that a sufferer can use the fire extinguishing gas quickly and extinguish a fire early. SOLVING MEANS A fire extinguishing gas spray device having a gas cylinder charged with pressurized fire extinguishing gas and to which is attached a sealing plate on an opening thereof, a seal breaking member that has a neb configured to break the sealing plate, a cylinder holder for attaching a threaded part, which is a mouth part of the gas cylinder, to a screw hole by screwing, and formed therein with the screw hole and a guide hole communicating each other, a seal breaking member holder to which the seal breaking member is attached at a lower end, movably stored in the guide hole, and biased to upwardly move with a spring, a communicating passage formed inside the seal breaking member holder, and formed with a valve attachment hole communicating with the guide hole and a conducting hole which is open to outside, a control valve which intermits the communicating passage and disposed in a middle of the passage, a control means configured to push up and down the seal breaking member holder, wherein the sealing plate is broken by a move of the seal breaking member, the fire extinguishing gas charged with the gas cylinder is jetted and introduced to the passage, and the fire extinguishing gas is jetted out from the conducting hole, wherein an alarm apparatus is provided on a periphery or inside thereof; the alarm apparatus comprises a receiver configured to receive a signal from an accident alarm which is installed indoors, an oscillator and a speaker configured to sound an alarm, and a location of the jetting apparatus for fire extinguishing gas is notified with the accident alarm and the alarm apparatus when a disaster occurs.
摘要:
La présente invention se rapporte à un appareil extincteur d'incendie, de préférence du type à pression auxiliaire. L'appareil comprend un corps contenant un agent extincteur de type poudre extinctrice, une tête d'extincteur fixée audit corps et destinée à recevoir les accessoires de commande de l'appareil, et un tube central, prévu à l'intérieur dudit corps, dans lequel est placé une cartouche sous pression contenant un gaz propulseur. L'appareil est caractérisé en ce que ledit corps comprend un centreur inférieur, prévus à l'intérieur dudit tube, pourvu d'un ou plusieurs canaux d'éjection traversant la paroi transversale dudit tube central et permettant d'expulser le gaz propulseur contenu dans ladite cartouche directement dans l'agent extincteur. L'invention concerne également un procédé d'extinction d'incendie utilisant de préférence un appareil extincteur d'incendie selon l'invention.
