Technical Field
[0001] This utility model relates to the field of fire protection engineering technology, and in particular to a multi-functional valve group for a high-pressure fine water mist fire extinguishing device. Background Technology
[0002] As modern buildings develop towards high-rise, large-scale, and multifunctional structures, the production scale and process complexity of industrial sites continue to rise. Traditional fire extinguishing methods are no longer sufficient to meet the fire safety needs of complex scenarios. High-pressure fine water mist fire extinguishing technology, with its advantages of efficient cooling, suffocation extinguishing, minimal water damage, and environmental friendliness, has been widely used in many fields. In subway systems, due to the enclosed space, dense population, and numerous electrical equipment, smoke spreads rapidly and rescue is difficult once a fire occurs. High-pressure fine water mist fire extinguishing systems can respond quickly, using fine water mist to reduce temperature and dilute smoke, ensuring the safe evacuation of passengers while minimizing damage to tracks and precision signaling equipment. Data centers store massive amounts of data, and traditional fire extinguishing methods may cause data loss due to water stains and agent residues. High-pressure fine water mist fire extinguishing technology, by precisely controlling the droplet size and spray intensity, can effectively extinguish the fire source while avoiding secondary damage to server equipment.
[0003] Existing high-pressure fine water mist fire extinguishing devices often lack precise flow control mechanisms, making it impossible to flexibly adjust the flow rate based on fire scale, spread rate, protected area size, environmental complexity, and actual conditions. In small fire scenarios, continuous and uniform water spraying can easily lead to water waste and unnecessary water damage. Conversely, in the face of large fires, a fixed flow rate is insufficient to meet the demands of high-intensity fire suppression, resulting in low extinguishing efficiency and hindering the full realization of the advantages of high-pressure fine water mist fire extinguishing technology. Currently, to address the flow control challenge of multi-functional valve assemblies in high-pressure fine water mist fire extinguishing devices, intelligent nozzle technology is commonly used. This technology utilizes built-in sensors to detect the fire situation in real time and precisely control the flow rate, greatly improving fire extinguishing efficiency and system flexibility. However, the integration of high-precision sensors, micro-intelligent control, and complex adjustment components, coupled with stringent manufacturing processes, results in high R&D and manufacturing costs, leading to high equipment procurement and maintenance expenses, which to some extent limits its large-scale application.
