Passive trigger gas fire-extinguishing device for electric power machine room

Abstract

The invention relates to the field of fire extinguishers and discloses a passive trigger gas fire-extinguishing device for an electric power machine room. The passive trigger gas fire-extinguishing device for the electric power machine room comprises a high-pressure gas tank, an intake valve and an exhaust port. The left side of the top of the high-pressure gas tank is provided with the exhaust port, and a rotating sprayer is arranged at the exhaust port. The rotating sprayer is in an elbow shape. One end of the rotating sprayer is concentrically and rotationally connected with the exhaust port of the high-pressure gas tank, and a seal ring is arranged between the rotating sprayer and the exhaust port of the high-pressure gas tank. A metal plug is plugged into the other end of the rotary sprayer, a gap exists between the first end of the metal plug and an opening of the elbow of the rotary sprayer, and the gap is filled with a fusible material. The metal plug is connected with a connecting line. The bottom of the high-pressure gas tank is provided with the intake valve. One end of the intake valve is connected with a high-pressure flame retardant gas bin through a gas guide pipe, and the other end of the intake valve communicates with the high-pressure gas tank. The high-pressure gas tank is filled with high-pressure flame retardant gas. A pressure difference control valve capable of detecting the pressure difference between the inside and the outside of the high-pressure gas tank is arranged on the right side of the top of the high-pressure gas tank. The passive trigger gas fire-extinguishing device for the electric power machine room can rapidly and effectively conduct spontaneous fire extinguishing.

Description

technical field [0001] The invention relates to the field of fire extinguishers, in particular to a passive trigger gas fire extinguishing device for an electric machine room. Background technique [0002] The power computer room plays a very important role in the power system. The equipment in the computer room of the electronic information system is complex and asset-intensive. It is necessary to ensure the normal operation of electronic equipment. Large and static electricity, etc. Once a fire occurs in the computer room, it will cause major losses and chaos in the order of power dispatching. Therefore, the fire protection system is an indispensable guarantee for the power computer room. [0003] For example, a "container valve and fire extinguishing device" disclosed in Chinese patent literature, its publication number is CN109568865A, this invention provides a container valve and a fire extinguishing device, wherein the container valve includes a valve body and a valve ...
