悬挂式超音速干粉灭火装置是日常生活中不常见的灭火器类型，但在消防方面具有独特的优势。那么，它的独特优势是什么呢？是如何灭火的呢？适用范围又是怎样的呢？下面川消小编为您分析：

The suspended supersonic dry powder fire extinguishing device is an uncommon type of fire extinguisher in daily life, but it has unique advantages in fire protection. So, what are its unique advantages? How did you extinguish the fire? What is the scope of application? Below, the editor of Chuanxiao will analyze for you:

悬挂式超音速干粉灭火装置由罐体、感温玻璃喷嘴、压力表、吊环等部件组成，配备ABC干粉灭火剂，适量的驱动气体氮气，在喷口部位装有感温玻璃喷嘴，当发生火灾时，温度升高到设定的动作温度，内部灭火剂分解、汽化和膨胀。

The suspended supersonic dry powder fire extinguishing device consists of a tank body, a temperature sensing glass nozzle, a pressure gauge, a lifting ring, and other components. It is equipped with ABC dry powder fire extinguishing agent, an appropriate amount of driving gas nitrogen, and a temperature sensing glass nozzle is installed at the nozzle. When a fire occurs, the temperature rises to the set operating temperature, and the internal fire extinguishing agent decomposes, vaporizes, and expands.

当膨胀力超过玻璃管的耐压强度时，玻璃管爆裂，汽化产生的二氧化碳和氨气，二氧化碳直接夺取空气中的氧气，氮气可有效降低空气温度，达到灭火的目的。

When the expansion force exceeds the compressive strength of the glass tube, the glass tube bursts and vaporizes to produce carbon dioxide and ammonia. Carbon dioxide directly seizes oxygen from the air, while nitrogen can effectively reduce the air temperature and achieve the purpose of extinguishing fire.

悬挂式超音速干粉灭火装置具有灭火效率高、腐蚀性小、绝缘性能好、无管道、无线路、结构轻、小、合理等优点。特别适用于油库、油漆仓库、配电室、干燥室等经常无人工作的场所，是室内有效的自动灭火设备之一。

The suspended supersonic dry powder fire extinguishing device has the advantages of high fire extinguishing efficiency, low corrosion, good insulation performance, no pipelines, no lines, light structure, small size, and rationality. Especially suitable for oil depots, paint warehouses, distribution rooms, drying rooms and other frequently unmanned workplaces, it is one of the effective indoor automatic fire extinguishing equipment.

悬挂式超音速干粉灭火装置的适用范围

Scope of application of suspended supersonic dry powder fire extinguishing equipment

A类火灾：固体有机物燃烧火灾。这些物质燃烧后，通常会形成木材、纸张、棉织物等热余烬。

Class A fire: Solid organic matter combustion fire. After combustion, these substances usually form thermal residues such as wood, paper, and cotton fabric.

B类火灾：液体或可熔固体燃烧的火灾。如汽油、柴油、煤油、沥青、醇、酯、醚、酮、油等火灾。

Class B fire: Fire caused by the combustion of liquids or fusible solids. Such as gasoline, diesel, kerosene, asphalt, alcohol, ester, ether, ketone, oil and other fires.

C类火灾：燃气火灾。如燃气、液化石油气、天然气等可燃气体的火灾。

Class C fire: gas fire. Fires caused by combustible gases such as gas, liquefied petroleum gas, and natural gas.

D类火灾：轻金属燃烧火灾。如钾、钠、镁、铅、海绵钛等轻金属火灾。

Class D fire: light metal burning fire. Such as potassium, sodium, magnesium, lead, sponge titanium and other light metal fires.

E类火灾：电气火灾。

Class E fire: Electrical fire.
