Cabinet type fine dry powder automatic fire extinguishing device

Cabinet type fine dry powder automatic fire extinguishing device

Features:

1. The fire extinguishing device can be used individually or in combination with multiple units, and can also be used in conjunction with suspended fire extinguishing devices to form an automatic fire extinguishing system without a pipe network (short pipe network).

2. The fire extinguishing device can be placed in a corner of the protective area or against the wall for easy installation, use, and maintenance.

3. The fire extinguishing device can have 2 nozzles or be connected to 4 or more nozzles, with a large protective capacity or area for a single device and fast fire extinguishing speed.

4. The fire extinguishing device can interface with the commonly used fire alarm control systems on the market, and start quickly and reliably.

Cabinet type fine dry powder automatic fire extinguishing device

Working Principle:
When a fire occurs, the temperature sensing glass ball of the fire extinguishing device expands and breaks due to heat, and the ultrafine dry powder is fully mixed under the driving pressure to form a gas powder mixture that sprays out. The mist powder comes into contact with the flame and extinguishes the fire through chemical and physical actions. Ultra fine dry powder has a chemical inhibitory effect on flame combustion; The suffocating effect on flameless combustion; The shielding and cooling effect on thermal radiation. Ultra fine dry powder has a small particle size (below 15 μ m), good flowability, and can suspend in the air for a certain period of time. Therefore, it can achieve both local fire extinguishing in non enclosed spaces and total flooding fire extinguishing in enclosed spaces.

Maintenance Instructions
a) The casing of the fire extinguishing device should be regularly cleaned of dust and dirt according to the environmental conditions, and any damage should be replaced in a timely manner.
b) Ultra fine dry powder does not require quality inspection within its effective period of use.
c) According to the relevant regulations of the national fire extinguishing system, the effective period of the fire extinguishing agent is 5 years, and the effective period of the fire extinguishing system is 10 years.

The device comprises a storage tank (2) containing a certain pressure extinguishing liquid, at least one nozzle (P) installed at a key fire prevention location and corresponding induction switch, pipelines (4) connecting the storage tank and nozzle respectively, at least one solenoid valve installed in the pipeline, and a control circuit including the induction switch.
