川消滅火器壓力不足的隱患
來源：http://www.xintli.net/ 日期：2022-06-08
消防成為生產工作重中之重。時值干燥天氣，公眾用火、用電、用氣十分頻繁，提高公眾消防意識十分重要。因此，很多朋友在家里配置了滅火器，你知道滅火器壓力不足的隱患有哪些嗎？對此，小編進行了歸納整理。
Fire safety has become the top priority of work safety. It is a dry day, and the public uses fire, electricity and gas very frequently. It is very important to improve public fire awareness. Therefore, many friends have equipped fire extinguishers at home. Do you know the hidden dangers of insufficient pressure of fire extinguishers? In this regard, Xiaobian summarized and sorted out.
滅火器指針顏色區域說明：
Description of fire extinguisher pointer color area:
紅色區域：滅火器壓力不足
Red area: insufficient pressure of fire extinguisher
綠色區域：滅火器壓力正常
Green area: fire extinguisher pressure is normal
黃色區域：滅火器壓力偏高
Yellow area: high pressure of fire extinguisher
滅火器壓力是根據貯氣瓶很大承受壓力來設計的。工作壓力指的是按額定充裝和加壓的滅火器在20℃環境中放置18小時后的內部平衡壓力。國內一般給滅火器壓力表分三個檔次，既三個顏色。指針在紅區欠壓狀態，在綠區的中間一般都達到了滅火器的工作壓力，而在黃區說明是超壓了，每個滅火器都有自己的工作壓力，壓力過高過低都會影響使用。
The pressure of the fire extinguisher is designed according to the great pressure on the gas cylinder. The working pressure refers to the internal equilibrium pressure of the fire extinguisher filled and pressurized according to the rated pressure after being placed at 20 ℃ for 18 hours. Generally, fire extinguisher pressure gauges are divided into three grades in China, namely, three colors. When the pointer is under voltage in the red zone, it generally reaches the working pressure of the fire extinguisher in the middle of the Green Zone, while in the Yellow Zone, it indicates that it is overpressure. Each fire extinguisher has its own working pressure, and too high or too low pressure will affect its use.

Hidden danger of insufficient pressure of fire extinguisher:
川消小編提醒各位要注意沒有滅火器必須一年一換藥劑的規定，只要壓力表的壓力合格，滅火器即可使用。（注意冬天低溫時，放在屋里溫度上升即可壓力回升合格）。滅火器失效后不允許仍然濫竽充數，這樣會給人錯覺，滅火器會失效，發生火災時貽誤戰機。這種情況，應責令整正，按新《消防法》第六十條一款處理，進行維修更換。
Sichuan Xiaobian reminds you that there is no stipulation that the fire extinguisher must be changed once a year. As long as the pressure of the pressure gauge is qualified, the fire extinguisher can be used. (note that when the temperature is low in winter, the pressure can rise to the standard when the temperature rises in the room). It is not allowed to make up the number after the fire extinguisher is out of service, which will give people the illusion that the fire extinguisher will be out of service and delay the fighter in case of fire. In this case, it shall be ordered to rectify, deal with it according to the first paragraph of Article 60 of the new fire protection law, and repair and replace it.
此外七氟丙烷壓力不足時，會在瓶組壓力表上體現出來，此時發生火災的話，七氟丙烷壓力不足，無法迅速有效的噴放到保護區，可能導致滅火延遲，很終滅火失敗。七氟丙烷滅火裝置內共有兩種物質：七氟丙烷、氮氣。七氟丙烷用來滅火，但是常壓下飽和蒸汽壓比較低只有0.39MPa，所以需要氮氣提供壓力。找滅火器年檢維修的廠家進行加壓維修就可以了，前提是你的滅火器必須是在保質期內的。
In addition, when the pressure of heptafluoropropane is insufficient, it will be reflected on the pressure gauge of the cylinder group. In case of a fire, the pressure of heptafluoropropane is insufficient and cannot be quickly and effectively sprayed to the protection area, which may lead to the delay of fire extinguishing and the failure of fire extinguishing. There are two substances in heptafluoropropane fire extinguishing device: heptafluoropropane and nitrogen. Heptafluoropropane is used to extinguish the fire, but the saturated steam pressure under normal pressure is relatively low, only 0.39mpa, so nitrogen is required to provide pressure. It is OK to find a manufacturer for annual inspection and maintenance of fire extinguishers for pressurized maintenance, provided that your fire extinguishers are within the warranty period.
