Types of fire sprinklers:
1, drooping type
Swing sprinkler is the most widely used sprinkler. It is installed on the water supply branch pipe in a swinging way, and sprinkles water in a parabolic way, spraying 80~ 100% of the total water to the ground. Protect rooms with ceilings, and arrange sprinklers under the ceilings. Drip sprinklers or ceiling sprinklers should be used.
2. Common types
Ordinary sprinklers can be directly installed or hung on the sprinkler pipe network, spraying 40%-60% of the total water downward and spraying a larger part to the ceiling. Suitable for restaurants, shops, warehouses, underground garages and other places. (The ordinary type is used less)
3, hidden spray
Concealed spraying is suitable for high-end hotels, houses, theaters and other places that need to ensure the smooth and tidy effect of smallpox.
The cover of the concealed spray is welded on the thread with fusible metal, with melting point of 57 degrees. Therefore, in case of fire, when the temperature rises, the cover will be removed first, and then when the temperature rises to 68 degrees (usually the nozzle), the glass tube will burst and water will be sprayed out. Therefore, the most taboo of hidden sprinkler is that the cover is stained with paint and coating, which will cause action failure.

In fact, in addition to those mentioned by Bian Xiao above, there is also a kind of fire sprinkler that is common in hotels and restaurants. This kind of nozzle is directly installed on the branch pipe of water supply, which is not only common in hotels, but also widely used in warehouses. When this kind of sprinkler is installed, it is usually under the ceiling or beam. In the office or corridor, the nozzle we often use is sidewall type. I hope you can make it clear.
