灭火器的使用关系到人们的生命财产。 在火灾初期，正确使用灭火器可以防止火灾的发生，但是真的灭火器就会让周围安危更加危险，那么假冒伪劣的灭火器和普通的灭火器有区别吗？ 有什么区别？

The use of fire extinguishers is related to the safety of people's lives and property. In the early stage of a fire, the correct use of fire extinguishers can prevent the occurrence of fire, but real fire extinguishers will make the surrounding safety more dangerous. Is there any difference between fake and inferior fire extinguishers and ordinary fire extinguishers? What's the difference?

正规厂家生产的灭火器使用磷酸二氢铵作为灭火剂的主要成分。 假冒灭火器是非常有害的。 可以从这几个方面进行分辨：

The fire extinguishers produced by regular manufacturers use ammonium dihydrogen phosphate as the main component of the fire extinguishing agent. Counterfeit fire extinguishers are very harmful. It can be distinguished from these aspects:

1.重量识别：

1. weight identification:

根据有关规定，3kg以下的干粉灭火器总重量的正负不超过3%，3kg以上的干粉灭火器总重量的正负不超过2%。 例如，5公斤的灭火器的很小重量不应小于4.9公斤。

According to relevant regulations, the total weight of dry powder fire extinguishers below 3kg shall not exceed 3%, and the total weight of dry powder fire extinguishers above 3kg shall not exceed 2%. For example, the small weight of a 5kg fire extinguisher should not be less than 4.9kg.

2、外观识别：

2. Appearance identification:

便携式灭火器配有自己的压力表。 一般来说，压力表上有三个色区。

Portable fire extinguishers are equipped with their own pressure gauges. Generally speaking, there are three color zones on the pressure gauge.

当指针指向红色区域时，表示灭火器内的干粉压力值太小，一旦发生火灾就无法喷出，说明灭火器出现故障。 这时候应该去正规的消防器材店补充干粉。

When the pointer points to the red area, it means that the pressure value of dry powder in the fire extinguisher is too small, and it cannot be sprayed in case of fire, indicating that the fire extinguisher is faulty. At this time, you should go to a regular fire equipment store to supplement dry powder.

当指针指向绿色区域时，表示压力正常，可以正常使用。 当指针指向该区域时，表示灭火器内的干粉压力过高。

When the pointer points to the green area, it indicates that the pressure is normal and can be used normally. When the pointer points to this area, it indicates that the dry powder pressure in the fire extinguisher is too high.

此外川消小编整理了相关内容，发现还能这样分辨：

In addition, Chuanxiao compiled relevant contents and found that it can be distinguished in this way:

看瓶体的钢印，它是灭火器的出厂日期；

Look at the steel seal of the bottle. It is the ex factory date of the fire extinguisher;

看软管的长度，一般四公斤以上的灭火器都配备的有软管，软管的长度不超过40cm；

According to the length of hose, generally, fire extinguishers with a weight of more than 4kg are equipped with hose, and the length of hose shall not exceed 40cm;

看灭火器的S标码，合格证和瓶身上有两个S标码，我们可以在消防产品信息网上面查询到，也可以用手机扫码查询。

Look at the s code of the fire extinguisher. There are two s codes on the certificate and the bottle. We can find them on the fire product information network or scan the code on the mobile phone.
