Automatic fire extinguishing system

Abstract

The invention discloses an automatic fire extinguishing system which comprises a fire extinguishing mechanism, a monitoring mechanism and an alarm mechanism. The fire extinguishing mechanism comprises a storage bottle containing a fire extinguishing medium and a fire trace tube contained in a cabinet body, a fixing mechanism used for fixing the fire trace tube is arranged in the cabinet body, a bottle head valve is arranged at a bottle opening of the storage bottle, a three-way valve is arranged between the bottle head valve and the end of the fire trace tube, one end of the monitoring mechanism is connected with a connector of the three-way valve, and the other end of the monitoring mechanism is connected with the alarm mechanism. According to the automatic fire extinguishing system, the fire extinguishing mechanism, the monitoring mechanism and the alarm mechanism are arranged, so that the automatic fire extinguishing system integrating automatic detection, automatic fire extinguishing and automatic alarm is formed, the pressure condition of the fire trace tube in the cabinet body and the storage amount of the fire extinguishing medium in the storage bottle can be monitored in real time according to information fed back by the monitoring mechanism under the normal condition, it is guaranteed that the fire extinguishing mechanism is in an effective working state, and fire extinguishing and alarm sending can be conducted in time in emergency situations.

Description

technical field [0001] The invention belongs to the technical field of fire protection, and in particular relates to an automatic fire extinguishing system. Background technique [0002] Fire is one of the most serious threats to nuclear power plants. Once a fire occurs in a nuclear power plant, it may cause a nuclear safety-related system accident, resulting in large economic losses, great social impact, and extremely serious consequences. Fire safety has become an important issue in the safety of nuclear power plants. Nuclear power fire safety has always been the focus of attention of nuclear power operators, the public and related institutions, and it is also a key factor for the vigorous development of nuclear power. As one of the main equipment of the power transformation and distribution system of nuclear power plants, the power distribution cabinet mainly plays the role of distributing and controlling electric energy. Many areas in the nuclear power plant, such as t...
