Automatic fire extinguishing system using gaseous extinguishing agent

Abstract

The invention provides an automatic fire extinguishing system using a gaseous extinguishing agent, the automatic fire extinguishing system includes a fire extinguishing agent storage device, a fire extinguishing agent output tube, a gas generator, a smoke- fire detection device and a control system, the smoke- fire detection device is used for detecting a smoke- fire signal in a fire prevention area and sending the smoke- fire signal to the control system, the control system command instructs the gas generator to generate, a gas generated by the gas generator starts the fire extinguishing agent storage device, the fire extinguishing agent storage device outputs an extinguishing agent to the fire extinguishing agent output tube, the fire extinguishing agent output tube sprays the extinguishing agent to the fire prevention area, and fire extinguishing agent storage devices starting according to fire conditions are arranged in the fire extinguishing agent storage device. The automatic fire extinguishing system can release fire extinguishing agent dosage according to fire conditions to ensure that fire in each detection area in fire condition can be extinguished by a fire extinguishing agent, and the fire extinguishing dosage agent can be automatically adjustable according to the requirement.

Description

technical field [0001] The invention relates to the technical field of fire fighting, in particular to an automatic fire extinguishing system using a gas fire extinguishing agent. Background technique [0002] Water is mostly used in daily fire fighting. For some areas that cannot be extinguished with water, such as archives, power distribution rooms, computer rooms, telecommunications centers, underground projects, oil depots, libraries, treasure rooms and other areas, gas is required. Extinguishing. At present, the fire extinguishing agents in gas fire extinguishing are all stored in high-pressure steel cylinders. The fire extinguishing agents include difluorochlorobromomethane 1211, trifluorobromomethane 1301, difluorobromomethane 1201, tetrafluorodibromoethane 2402, heptafluoropropane, etc., which are more commonly used Heptafluoropropane, heptafluoropropane (HFC-227ea) fire extinguishing agent is colorless, odorless, has zero ozone depletion potential, meets environmen...

AI Technical Summary

Problems solved by technology

However, if the electric control valve has some defects, it cannot be started normally, and the fire extinguishing agent in the fire extinguishing agent storage tank cannot be released, and the control valve loses its function, which is useless. At this time, manual operation is required to open the fire extinguisher. The control valve on the tank is rarely designed with a flashlight integrated. Some control valves have a flashlight integrated mechanism design. Not only are they large in size and complex in structure, but they are prone to failure and cannot be opened due to their many parts. Therefore, less reliable
