Description

A fire extinguisher and its pressure alarm device

technical field

The utility model relates to a fire extinguisher, in particular to a pressure alarm device for the fire extinguisher.

Background technique

The bottled fire extinguisher, which is an important facility for fire protection, will gradually reduce and disappear the pressure in the bottle due to long-term storage. Once a fire breaks out and needs emergency use, if the pressure in the steel cylinder is insufficient, it will not be able to play its role, often leading to disaster. Therefore, it is very important to monitor the internal pressure of the fire extinguisher. The fire extinguishers currently on the market are all equipped with mechanical pressure gauges as an alarm device, but the disadvantages of the existing pressure gauges are that the surface is too small and the indication is not obvious enough. The management patrol personnel must approach the fire extinguisher to monitor the pressure change. , causing great trouble to maintenance and inspection. Especially in social life, people have not developed the habit of checking the pressure gauge of the fire extinguisher frequently, resulting in many fire extinguishing facilities having been stored for a long time and the pressure disappears without realizing it, which brings great hidden dangers to safety.
