How Fused Sprinkler Heads Work

Fused Sprinkler Heads consist of a two-piece metal element cast with a heat-sensitive alloy. When the ambient temperature around the sprinkler head reaches a certain temperature, the alloy melts and the metal parts separate, causing the chimney lid to fall off. Then the water is released.

And what is a sprinkler head with fusible link?

Fusible link sprinklers to all wet sprinklers are held closed by a fusion chain or glass bulb with heat sensitive liquid. A fusible coupling nozzle head comprises a two-piece metal element cast from a heat-sensitive alloy. The ■■■■■■■ holds the tube cap or plug in place.

Do you also know how sensitive sprinkler heads are?

Sprinkler systems are actually quite sophisticated and heat sensitive, so sprinklers are only activated when the temperature reaches fire-relative temperatures, typically between 155 and 165 degrees Fahrenheit. .

Similarly, you may be wondering how hidden sprinklers work?

A hidden sprinkler head in the house is a fast-acting two-tier design about the size of a downlight. When you reach the fireplace, the flat plate falls off the frame and the sprinkler head deflector drops below the roof level.

What liquid does an irrigation head contain?

The liquid in the sphere of the spray head is a mixture of alcohol and water or glycerin and water. The% of each is changed to determine the head activation temperature. The color comes from a dye and indicates the activation temperature.

At what temperature does the spray head turn off?

These are the sprinkler caps. They are designed to fall off the roof when it gets too hot (like 120 ° F) so that the nozzles can be sprayed freely when they reach their magical temperature.

What does the K factor mean in sprinklers?
