46. The pipe network system of the high-pressure fine water mist fire extinguishing system uses stainless steel pipes (304) with rust resistance, as once rust occurs, the rust deposits in the pipeline can block the nozzles, leading to system failure. The cleanliness of the pipe network system is crucial for the high-pressure fine water mist fire extinguishing system; therefore, strict flushing, pressure testing, and blowing must be conducted after the pipeline installation. All pipes are焊接 using the argon arc welding method.

47. High-pressure fine mist pump set (water supply unit) system composition: fine mist nozzles (open, closed), filters, zone control valve sets (boxes), water tanks, and stainless steel pipelines, etc.

48. High-pressure fine mist pressure switch:

2. Connect one cable wire to the common terminal.

3. Connect the other cable wire to the normally open contact.

4. After wiring is complete, secure the cover and tighten the screws to restore the original condition.

49. High-pressure fine mist open system working principle: In the quasi-operational state, the fine mist system maintains a certain pressure in the pipeline from the pump group outlet to the valve box before the zoning control, when the pressure drops below the set start pressure of the pressure maintaining pump by 1Mpa, the pressure maintaining pump is activated, ensuring the pipeline of the system maintains a stable pressure of (1-1.2) MPa.

50. Working Principle of High-Pressure Fine Mist Open System: Upon detection of a fire signal by the detector, the fire alarm control main unit transmits signals to the electric ball valve in the pump group control cabinet and the division control valve box, causing the high-pressure plunger pump to automatically start and the electric ball valve in the division control valve box to open. The high-pressure water then forms a mist through the pipes and nozzles to extinguish the fire.

51. High-pressure fine mist open system working principle: The pressure switch feedback system in the zone control valve box sends out a release signal, upon which the main unit receives the feedback signal and联动ly activates the spray indicator light.

52. High-pressure fine mist closed-loop system working principle: In the standby condition, the fine mist system maintains a certain pressure from the pump group outlet to the pipeline before the zone control valve box. When the pipeline pressure drops and is lower than the set start-up pressure of the pressure maintenance pump by 1MPa, the pressure maintenance pump starts up to maintain a stable pressure of the system pipeline (1-1.2 MPa).

53. High-pressure fine mist closed-loop system operation principle: Upon detection of a fire signal by the detector, the fire alarm control main unit transmits the signal to the pump group control cabinet. The high-pressure plunger pump starts, and the electric ball valves within the zoning control valve box are opened. The entire pipeline is filled with high-pressure water. When the glass ball in the closed sprinkler head reaches the activation temperature, the glass ball breaks, and the high-pressure water forms a mist through the nozzle for fire extinguishing.

54. High-pressure fine mist closed system working principle: The pressure switch feedback system in the zone control valve box sends out a discharge signal, upon which the main unit receives the feedback signal and联动ly activates the spray indicator light.

55. Automatic start of high-pressure fine mist system: When a fire occurs within the protected area, the fire detector detects the fire and sends a signal to the fire alarm controller. The fire alarm controller confirms the area of the fire based on the address of the fire detector, then sends a control signal to activate the fire extinguishing system, starting the high-pressure plunger pump and opening the corresponding zone control valves.

56. Automatic activation of high-pressure fine mist system: After the zone valve is opened, water in the system pipes quickly reaches working pressure (closed pre-action system waits for the closed spray head to sense the bursting temperature, then the glass ball automatically bursts), and sprays by forming a misting effect through high-pressure fine mist nozzles, producing fine mist to extinguish fires.

57. Manual Electric Start for High-Pressure Fine Mist System: Remote Start-up: When a fire is detected, and before the fire detector activates, the electric valve button on the corresponding zone control valve box at the remote fire control center can be pressed to initiate the zone valve, enabling the pump to automatically start and supply water for fire extinguishing.

58. High-pressure fine mist system manual electrical start: Local start: When a fire is detected, the local section control valve box can be opened to activate the area valve by pressing the area valve control button for extinguishing.

59. Mechanical emergency start of high-pressure fine mist system: In the event of failure of the fire alarm system, the handle on the area valve can be manually operated to open the area valve for fire extinguishing. Note: Emergency start of a closed fine mist system can be achieved by breaking the glass ball of the closed spray head.

High-pressure fine mist is a water mist produced by professional equipment under low design working pressure, with a mist drop accumulation distribution of Dv0.99 < 300μm on a plane 1m from the nozzle. High-pressure water mist has functions such as cooling, humidifying, dust control, fire prevention, and landscaping, and can be used in industrial, breeding, planting, and entertainment fields.

61. Mechanism of High-Pressure Fine Mist Fire Extinguishing: Rapid Cooling and Local Asphyxiation—Advanced dual-action fire extinguishing mechanism: Water emitted from a nozzle of a special material forms a mist with particle sizes between 10-100 micrometers, having a smaller surface area. Upon contact with fire, it quickly vaporizes, expanding in volume up to 1700-5800 times, absorbing a large amount of heat, thereby rapidly lowering the temperature of the burning surface; simultaneously, the vaporized water forms steam, enveloping and covering the entire combustion area, causing the fire to suffocate due to oxygen deprivation.

62. The extinguishing mechanism of high-pressure fine water mist: The heat absorption is calculated based on the latent heat of 100℃ water evaporation at 2257 kJ/kg. Each fine water mist nozzle can absorb heat at a rate of approximately 300 kW per kilogram of fine water mist emitted, demonstrating its high heat absorption rate and strong cooling effect.

63. The extinguishing mechanism of high-pressure fine water mist: Asphyxiation. After the fine water mist is heated and vaporized, its volume rapidly expands to 1700~5800 times, with steam closely enveloping the surroundings of the burning material, forming a barrier to block the entry of fresh air. This causes the combustion to be interrupted due to lack of oxygen.

64. The extinguishing mechanism of high-pressure fine water mist: After the fine water mist evaporates, the resulting steam quickly envelops the burning material, flames, and smoke, effectively blocking the radiant heat of the flames and preventing the spread of the fire.

65. Mechanism of Fire Extinguishing by High-Pressure Fine Water Mist: The high-pressure fine water mist not only has the effect of smoke and dust removal but also cleans away smoke and waste. This is because the ash, soot particles, and harmful gases from combustion adhere to the fine water droplets and are thus cleaned away. Statistics show that in fire accidents, 70% of deaths are not due to direct burns, but rather from inhaling the toxic fumes and smoke caused by high temperatures.

66. The extinguishing mechanism of high-pressure fine water mist: Involves wetting action—capable of extinguishing oil fires. The high-pressure fine water mist has a high particle velocity, allowing it to penetrate the surface of burning oil materials, wetting them. This prevents the further generation of flammable gases and combustion materials. Additionally, due to the small size of the water mist particles, they do not disturb the liquid surface, causing splashes, thereby achieving the purpose of extinguishing fires and preventing their spread.

67. The fire extinguishing mechanism of high-pressure fine water mist: Three-dimensional movement—explanation for full or partial extinguishing. During the atomization of high-pressure fine water mist, some smaller diameter droplets do not all travel in the direction of the jet. The droplets produce lateral and upward swirling movements in the direction of the jet, entering the upper space of the nozzle. This allows the fine water mist to fill the entire space of the protected area. The smaller the particle size, the more intense the lateral transfer phenomenon. This is also known as three-dimensional fire extinguishing.

68. Fire extinguishing mechanism of high-pressure fine water mist: Explanation of its ability to extinguish electrical fires, and why it doesn't conduct electricity when extinguishing electrical fires: The droplets are small in diameter (10-100 micrometers), and after being sprayed, they are discontinuous, capable of remaining suspended in the air for extended periods. It requires a large quantity and significant time for the water mist to coalesce and condense, making it difficult to form a continuous conductive water flow or surface area on the electrode, and its resistivity is slightly lower than that of air.

69. An open-type fine water mist fire extinguishing system uses water as the medium, and employs special atomizing nozzles to break the water flow into tiny droplets under specific pressure (usually 14 MPa) for fire extinguishing. It is a fixed fire extinguishing system characterized by economy and wide applicability, and has become a significant technology to replace Halon fire extinguishing systems, with a promising application prospect.
