If the pressure gauge of the fire extinguisher is damaged and the interface of the pressure gauge is broken, will the fire extinguisher leak?
Whether there is no breach is not important, mainly the pressure indicator in the yellow area, green area proved to have no drainage pressure, red zone without pressure or too small, yellow zone pressure is too large, in case of high temperature and so on, the explosion is more serious, green zone safety. Rubber hose fire equipment stores have sold 2-5 yuan, the inner layer has not split open, you can use, indoor storage extinguishers can not exceed 2 years, to overhaul once (pointer in the green zone should be detected), 1 years, 1, the most security testing.
The pressure gauge of the extinguisher won't leak.Domestic fire extinguishers generally pressure gauges are divided into three grades, both three colors.1, when the pressure gauge pointer refers to the red part, indicating that the pressure in the bottle is not enough, the fire extinguisher can not be used properly.2, refers to the yellow part, indicating that the pressure is too large, prone to danger.3, when you refer to the green part, it shows that the fire extinguisher is normal.
The bottle body collision, deformation and cracking damage of nozzle nozzle is not to use the fire extinguisher pressure gauge in the red zone under voltage, need maintenance, seal damaged also need maintenance, depression
