Description

Technical Field

[0002] In view of the fact that firefighting teams deal with complex types of fires and undertake diverse firefighting tasks, domestic and foreign institutions have begun to focus on the development of universal and efficient foam fire extinguishing agents in recent years. The foaming method of multi-component agents is expected to break the technical barriers of traditional water-based foams and become an important development direction of foam fire extinguishing technology in the future. In order to achieve efficient combination of multi-component agents in actual firefighting combat scenarios, the foam proportion mixing device is the core component of the entire system.
