Description

Technical Field

[0001] The invention relates to a fire extinguishing device, in particular to a novel environmentally friendly cabinet-type fire extinguishing device with external visualization, belonging to the technical field of fire extinguishing devices. Background Art

[0002] Cabinet fire extinguishing device, also known as HFC-227ea gas fire extinguishing device or prefabricated HFC-227ea fire extinguishing system, is a highly efficient gas fire extinguishing equipment. This device is widely used in small spaces and medium and high-risk places such as computer rooms, libraries, archives, power distribution rooms, data centers, and communication base stations. The main components of the cabinet fire extinguishing device include fire extinguishing agent bottle group, one-way valve, signal feedback device, release device, cabinet and pipeline, etc. When a fire occurs in the protected area, the fire detector will send a fire signal. This signal will be sent to the fire extinguishing controller. After confirming the fire, the sound and light alarm will be activated, and the fire extinguishing controller will send a start signal to start the solenoid valve of the gas bottle group. After the solenoid valve is opened, the driving gas will be released. Under the pressure of the driving gas, the fire extinguishing agent will be released into the protected area to implement fire extinguishing.
