灭火器的压力表有三个区域，分别为红色、绿色以及黄色，当然不同颜色代表的状态也是不一样的，下面就跟着川消小编针对这一点来讲讲相关内容吧。

The pressure gauge of the fire extinguisher has three areas, namely, red, green and yellow. Of course, different colors represent different states. Let's talk about the relevant contents according to this point.

个区域是红色区，指针指到红色区，表示灭火器内干粉压力小，不能喷出，已经失效。这时应该到正规的消防器材店重新充装干粉。

The first area is the red area. The pointer points to the red area, indicating that the pressure of dry powder in the fire extinguisher is small, it cannot be sprayed, and it has failed. At this time, you should go to the regular fire equipment store to refill dry powder.

第二个较窄的区域是绿色区，指针指在该区，表示压力正常，可以正常使用。

The second narrow area is the green area. The pointer refers to this area, indicating that the pressure is normal and can be used normally.

第三个黄色区域，表示灭火器内的干粉压力过大。黄格区是灭火器生产或维修过程中给厂家用到的充气危险区，一般情况下，正规厂家都会充在绿格区，若指针出在黄格区则表示压力过大，但并不表示就使用时无效，依然可以喷出干粉，但却有爆破、爆炸的危险。这样状态的灭火器，建议是拿到正规的消防器材店重新充装干粉。

The third yellow area indicates that the dry powder pressure in the fire extinguisher is too high. The Yellow grid area is a dangerous area for inflating the factory's household during the production or maintenance of fire extinguishers. Generally, regular manufacturers will fill the green grid area. If the pointer is in the Yellow grid area, it means that the pressure is too high, but it does not mean that it is invalid when used. It can still spray dry powder, but it has the risk of explosion and explosion. For fire extinguishers in this state, it is recommended to take them to a regular fire equipment store and refill them with dry powder.

总之，灭火器的压力表指针指在“绿色区域”时表示压力正常。这时的压力值是在1.3mpa左右。当压力表指针处于绿色位置，是意味着灭火器能放心使用，而当针处于红色或黄色位置时，需要及时维修，以免带来不必要的麻烦。

In short, the pressure gauge pointer of the fire extinguisher indicates that the pressure is normal when it is in the "green area". At this time, the pressure value is about 1.3mpa. When the pointer of the pressure gauge is in the green position, it means that the fire extinguisher can be used safely. When the needle is in the red or yellow position, it needs to be repaired in time to avoid unnecessary trouble.

此外川消灭火器是能够携带的一种灭火器工具，内部放置了化学物品，用来救火使用的。其实灭火器是我们生活中比较常见的一种防火设施，是能够放在公众场所或者是可能发生火灾的一个地方。灭火器的种类也是比较多的，有手提式、储压式、泡沫、干粉等。您要根据自己的实际情况来选择哪一种类型的。

In addition, Sichuan fire extinguishing firearm is a kind of fire extinguisher tool that can be carried. Chemicals are placed inside it for fire fighting.

There are many types of fire extinguishers, including portable, pressure storage, foam, dry powder, etc. You should choose which type according to your actual situation.
