What is the temperature of the nozzle used in the kitchen?

Spray head, the kitchen of a star-rated hotel, has ceiling spray and no ceiling spray. The temperature in the kitchen is 79 or 93 degrees.

According to different explosion temperatures, the nozzles can be divided into 57~68~79~ 130 or others. According to the spray characteristics, it can be divided into k=80,115,200,360.

According to the spraying performance, it can be divided into vertical (upward installation, more upward spraying, and some downward space without smallpox, such as basement), suspended ceiling (with smallpox, the sprinkler is downward, more downward spraying, and some upward spraying) and concealed sprinkler (high-grade decoration place).

According to the diameter of glass outlet, it can be divided into general energy type and rapid reaction type.

In addition, according to the size of the caliber, it can be divided into ordinary and expanded types, open and closed types, side wall types, water curtain types, water nozzles and other nozzles.

Working principle of fire sprinkler: The red liquid on the fire sprinkler is extremely sensitive to heat. When the temperature rises, it expands rapidly, breaking the glass where it is installed, and then the pressure sensor in the glass will make the fire sprinkler pump spray water.
