Gas fire extinguishing module with fault-tolerant pressure control system

Abstract

The claimed utility model relates to the field of fire-fighting equipment, in particular to automatic volumetric fire extinguishing systems using gaseous fire extinguishing agents (GFE) to extinguish fires of classes A, B, C, as well as fires of electrical equipment under voltage. In a module containing a cylinder for a fire extinguishing agent, made of two welded first and second elliptical bottoms, a shut-off and starting device including a shut-off valve, a built-in first membrane safety device, an electromagnetic starting device and an autonomous starting element in the form of a destructible thermo-flask, a spray nozzle, a pressure indicator and a cylinder fastening unit, what is new, according to the claimed utility model, is that, that at the top of the first elliptical bottom of the cylinder there is a welded fitting equipped with two threaded connections - one for connecting a flexible adapter hose with the first pressure gauge and the second for an additional second membrane safety device with the ability to emergency release excess pressure in the event of failure of the first membrane safety device, and the shut-off and starting device additionally includes a second pressure gauge with the ability to simultaneously monitor the pressure in the gas and liquid phases of the fire extinguishing agent, while the module is equipped with a mounting bracket designed with the ability to be bolted to side fasteners located symmetrically on both sides of the welded fitting and a digital identification tag containing a machine-readable code with access to a digital passport. The technical result is expressed in: increasing the accuracy of pressure control; increasing the fault tolerance of the pressure control system; increasing the operational safety of the module; increasing the mechanical reliability of the structure; and improving the operational characteristics of the module.
