1.Working principle

Suspended gas fire extinguishing devices can be divided into two types based on the different starting methods: fixed temperature type and electric type. The fixed temperature suspension gas anti-inflammatory device mainly relies on the fixed temperature glass ball on the valve to expand and rupture during a fire, opening the valve and spraying the extinguishing agent; Electric suspended gas fire extinguishing devices are generally used in conjunction with alarm system equipment such as fire detectors, manual start buttons, and fire alarm controllers; When a fire occurs in the protective zone, the fire detector acts, and the fire alarm controller confirms the fire alarm and outputs a start signal, causing the fire extinguishing device to start and dispense the extinguishing agent. Alternatively, after the personnel confirm the fire alarm, they can press the manual start button and electrically open the valve to dispense the extinguishing agent and extinguish the fire.

2. Product Features and Scope of Application

A type of fire extinguishing device that pre assembles storage containers, container valves, nozzles, etc. into independent hanging installations and can automatically or manually start the spraying of extinguishing agents in case of fire. The valve design of the suspended gas fire extinguishing device has a large diameter, short spraying time, and fast fire extinguishing. Due to the lack of pipeline network, construction and installation are simple, reducing project investment; At the same time, the fire extinguishing device is installed above the protective zone, which does not occupy the ground space of the protective zone.

Mainly suitable for small protective areas such as distribution rooms, transformer rooms, instrument and equipment rooms, small oil depots, computer rooms, software libraries, communication rooms, archives and cultural relics data rooms.

3. Composition of suspended device

The suspended device mainly consists of a tank body, a temperature sensing release component, a glass ball electric initiator, a pressure gauge, a pressure signal feedback device, a support, etc. It has two starting forms: fixed temperature and electric.
