Description

TECHNICAL FIELD

[0001] The utility model relates to fire extinguishing equipment technical field, concretely is a kind of gas fire extinguishing equipment container valve automatic opening device. BACKGROUND

[0002] Gas fire extinguisher is a kind of equipment using gas fire extinguishing agent to extinguish fire, commonly used in electrical equipment, computer room, data center and other places, especially those places that are more sensitive to equipment damage. Unlike traditional water-based fire extinguishers or foam fire extinguishers, gas fire extinguishers suppress fires by reducing oxygen concentration or through chemical reactions. Common gas fire extinguishing agents include heptafluoropropane, carbon dioxide, and halon, which was once widely used but has gradually been phased out. The heptafluoropropane solenoid valve is opened or closed by electromagnetic action, thereby controlling the gas flow in the fire gas extinguishing system. When the system detects a fire, the controller sends a signal to the heptafluoropropane solenoid valve, which opens the solenoid valve, allowing heptafluoropropane gas to flow into the sprinkler pipe, achieving the effect of extinguishing fire.
