Factory making Spray Bottle Nozzles - Percussive type water curtain sprinkler – Minshan Detail:

Working principle:

 

During a fire, the sprinkler continuously sprays water mist on the exposed heat absorbing surfaces of various buildings near the fire area to prevent the heat absorption of the exposed surfaces and the spread of fire to protect the safety of various buildings.

 

Specification:

 

MODEL Nominal Diameter Thread Flow Rate K Factor Style
MS-WCS DN15 R1/2 80±4 5.6 fire sprinkler
DN20 R3/4 115±6 8.0
DN25 R1 242 16.8

 

How to use:

 

The water spray nozzle used in the water spray fire extinguishing system is a nozzle that uses the principle of centrifugation or impact to decompose water into small water droplets under a certain water pressure. The arrangement of the nozzles in the water spray fire extinguishing system is the key to ensuring the fire extinguishing effect of the water spray fire extinguishing system. Only with proper arrangement can the fire extinguishing effect be maximized.

The number of sprinklers in the water spray sprinkler system should be determined according to the design spray intensity, protection area, and characteristics of the water spray sprinklers. The water mist can be directly sprayed and covered with protection objects. If the requirements cannot be met, the number of water mist nozzles should be increased. The protected area refers to the total exposed surface area of ​​the protected object; when the protected object is a plane, the protected area is the planar area of ​​the protected object; when the protected object is three-dimensional, the protected area is the entire external surface area of ​​the protected object; when the protected object is shaped When irregular, it should be determined according to the regular shape of the protected object, and the surface area of ​​the contained object should not be smaller than the actual surface.

The safety net distance between the water mist nozzles, pipes and live parts of electrical equipment shall comply with the relevant standards; the distance between the water mist nozzles and the protected objects shall not be greater than the effective range of the water mist nozzles. The effective range refers to the horizontal distance between the nozzles when the spray head sprays horizontally.

If the object of protection is an oil-immersed power transformer, the water mist nozzles should not only be around the transformer and not the top; the water mist on the top of the protection transformer cannot be sprayed directly to the high voltage bushing; the horizontal distance between the water mist nozzles The vertical distance must meet the requirements of the water mist cone; the oil pillow, cooler and oil collection pit should be protected by water mist nozzles. If the object of protection is a cable, the spray should completely surround the cable. If the protection object is a conveyor belt, the spray should completely surround the conveyor head, tail, and up and down belts.

Application :

 

In fire protection, the atomizing sprinkler quickly vaporizes through its fine atomized particles after being heated, and a large amount of heat is absorbed by the combustibles and the fire area, thereby reducing the surface temperature of the combustibles and achieving the purpose of flame retardancy. At the same time, after vaporization, water vapor fills the fire field, repels the air in the fire field to the maximum extent, and reduces the oxygen content. After the fire is extinguished, the fine water mist quickly volatilizes, which will not cause water pollution to the fire site and will not damage the items due to the fire. Common fire nozzles include fine water mist open sprinkler and fine water mist closed sprinkler. It is precisely the characteristics of the above atomizing sprinkler that are widely used in cultural relics museums, libraries, ships, ancient Buildings, oil depots, tunnels and military equipment.
