Abstract

An automatic fire-extinguishing CO2 system is composed of a fire extinguishing controller and a steel cylinder full of CO2. A container valve composed of valve seat, valve body and valve cover is arranged on the top of steel cylinder. Said valve body is divided into upper and lower valve chambers. A valve rod passing through the valve cover has a piston associated with upper valve chamber and a sealing cover at its lower end. A tube between said upper and lower valve chambers can be turned on or off under the control of an electromagnetic valve controlled by said fire extinguishing controller.

Description

technical field [0001] The invention relates to a gas automatic fire extinguishing system, especially a carbon dioxide automatic fire extinguishing system. Background technique [0002] Carbon dioxide automatic fire extinguishing system equipment is an efficient and reliable automatic fire extinguishing equipment, which is combined with automatic fire detection and alarm devices to form a fully automatic fire alarm monitoring, alarm and fire extinguishing system. Because it has the advantages of non-toxicity, low price, good insulation, easy cleaning after disasters, and refillable use, it has been widely used. At present, the gas fire extinguishing system products at home and abroad mostly use a single solenoid valve with a small nitrogen cylinder to start the fire extinguishing equipment, that is, the fire alarm controller controls the solenoid valve on the small nitrogen cylinder. After the solenoid valve is opened, a small nitrogen gas is released. The high-pressure gas...
