Fire sprinklers are used in fire sprinkler systems. When a fire occurs, water is sprinkled through the sprinkler splash plate to extinguish the fire. It is divided into pendant sprinklers, upright sprinklers, ordinary sprinklers, and side sprinklers. Wall-type sprinklers, etc. Under the action of heat, the sprinkler will start automatically within a predetermined temperature range, or be activated by the control device according to the fire signal, and sprinkle water according to the designed sprinkler shape and flow. In the event of a fire, fire-fighting water is evenly sprinkled through sprinklers to control the fire in certain areas.

The drooping sprinkler is the most widely used sprinkler. It is installed drooping on the water supply branch pipe. The shape of the sprinkler is parabolic, spraying 80-100% of the total water to the ground. To protect rooms with suspended ceilings, sprinklers should be arranged under the suspended ceilings. Pendant or ceiling sprinklers should be used.

The upright sprinkler is installed upright on the water supply branch pipe. The spraying shape is parabolic. It sprays 80-100% of the total water volume downwards, while a part of it is sprayed to the ceiling. It is suitable for installation on many moving objects and is prone to impact. In places such as warehouses, it can also be concealed on the roof of the room ceiling mezzanine to protect the ceiling boron with more flammable materials. (In places where the ceiling is not used, when the water distribution pipe is arranged under the beam, the vertical type should be adopted. The parts that are vulnerable to collision should be used with protective cover sprinklers or ceiling sprinklers)

Ordinary sprinklers can be installed directly, or they can be installed downwardly on the sprinkler network, spraying 40%-60% of the total water volume downward, and the larger part is sprayed to the ceiling. Suitable for restaurants, shops, warehouses, underground garages and other places. (The common type uses less)

Side-wall type sprinklers are installed against the wall, suitable for installation in places where space is difficult to pipe. They are mainly used in lightly dangerous parts of buildings such as offices, halls, lounges, corridors, and guest rooms. Side wall type sprinklers can be used in light-dangerous and medium-dangerous I-class rooms and offices with a horizontal top plate

Concealed spraying is suitable for high-end hotels, residences, theaters and other places where the ceilings need to be clean and tidy.

The cover of the concealed spray is welded on the thread with fusible metal, and the melting point is 57 degrees. Therefore, in the event of a fire, the temperature rises to cause the cover to fall off first, and when the temperature rises to 68 degrees (a general sprinkler head), the glass tube bursts and water jets out. Therefore, the most taboo of the concealed sprinkler is the paint and paint on the lid, which will cause malfunction.
