Abstract

The invention discloses a gas extinguisher with signal feedback and manual emergency operation. The gas extinguisher comprises an electromagnetic drive device and a driving cylinder valve which cooperate with each other. The electromagnetic drive device contains a pedestal, a thimble assembly installed inside the pedestal and an electromagnet assembly which drives the thimble assembly to start the driving cylinder valve. The central section of the pedestal is provided with a centre hole. The thimble assembly is in sliding fit inside the centre hole. The thimble assembly is equipped with a compressed tablet. The pedestal is also provided with an internal cavity. A microswitch touched by the compressed tablet is arranged inside the internal cavity. After touched, the microswitch emits an action feedback signal. The gas extinguisher provided by the invention has advantages of stable and reliable action, high efficiency, outstanding waterproof and dustproof effect, abundant and practical function, simple and reliable manual emergency operation and convenient installation and maintenance.

Description

Technical field [0001] The invention relates to a gas fire extinguishing device, in particular to a gas fire extinguishing device with signal feedback and emergency manual operation. Background technique [0002] Fire extinguishing systems using gas as the fire extinguishing medium are widely used in important facilities and buildings such as subways, tunnels, airports, shopping malls, etc., for fire protection of computer rooms, substations (rooms), archives and other places. After continuous application and development, its ease of installation and use and outstanding fire extinguishing effect have been widely accepted and recognized. [0003] The electromagnetic drive device receives the action signal from the gas fire extinguishing controller, opens the drive bottle valve to release the drive gas, opens the selection of the protected area and the corresponding extinguishing agent bottle valve, and releases the extinguishing agent to the protected area to achieve fire protection...
