Foam fire extinguisher pressure gauge: sentinel guarding the liquid barrier

In the fire scene, the foam fire extinguisher is like a flowing liquid shield, which extinguishes the fire by creating a physical barrier to isolate the burning material from oxygen. The key to supporting this process is the foam fire extinguisher pressure gauge, a precision component with a diameter of less than five centimeters. Compared with dry powder fire extinguishers, the pressure gauge of foam fire extinguishers not only has to deal with more complex fluid characteristics, but also needs to maintain a stable pressure balance under special circumstances. It is itself a game about safety and efficiency.

The special mission of the foam fire extinguisher determines the severity of the pressure detection system. When the fire involves oil, solvents or chemical liquids, the foam needs to evenly cover the surface of the burning material at a specific flow rate to form a closed isolation layer. If the coverage density does not meet the standard, the fire will rekindle. In chemical storage spaces such as laboratories, the precise monitoring of the pressure gauge becomes the second pair of eyes of industrial operators. Before operation, ensure that the pointer is stable in the safe zone, which not only affects the immediate fire extinguishing ability, but also affects the long-term reliability of the equipment.

From a deeper perspective of technological evolution, the precision leap of pressure gauges has promoted the intelligence of foam fire extinguishing systems. As firefighting technology continues to innovate, the foam fire extinguisher pressure gauge, a seemingly traditional component, is still adhering to the essence of fire safety.
