Fire equipment and accessories: Fire sprinkler system, fire pipeline, K80 suspended sprinkler.
Product Introduction:
This product is a fire sprinkler head used in automatic sprinkler systems. Its specific functions are as follows:

Early fire response:
The internal red glass bulb (68°C temperature-sensitive type) will expand and break when the ambient temperature reaches the set value, triggering the sprinkler head to automatically open and spray water on the fire source area immediately to prevent the fire from spreading.
Precise fire control / extinguishing:
The top splash plate (gear-shaped structure) can evenly disperse the sprayed water into water mist / water curtain, covering a certain range around, effectively reducing the temperature in the fire area and isolating oxygen to achieve local fire extinguishing or control the spread of the fire.
System linkage assistance:
After the sprinkler head is activated, the water pressure in the fire protection pipeline will drop, triggering components such as the alarm valve and pressure switch in the system, which will automatically start the fire pump to replenish water and send a signal to the fire alarm controller to alert personnel for evacuation or rescue.
Unanned area protection:
In scenarios such as at night or in unoccupied buildings, it can autonomously start fire suppression to prevent small fires from developing into large-scale fires.

Spark DN20 Fire Sprinkler Head: Brass Protection, A Reliable Fire-Fighting "Vanguard" for Multiple Scenarios

Building fire safety gains another reliable gear — the domestically produced Spark DN20 fire sprinkler head, with its brass durability and multi-temperature zone adaptability, has become a popular configuration in current fire protection systems, strengthening the initial fire protection network for various premises.
 

Core Specifications: Brass Base + Multi-Temperature Adaptation, Balancing Durability and Precision

This sprinkler head uses brass as its main material, offering corrosion resistance and aging resistance, making it suitable for various pipeline connection scenarios. Its core specification is a DN20 interface, compatible with mainstream fire protection pipelines and adaptable to the piping systems of light/moderate hazard locations.

Its temperature-sensing options cover a multi-range of 68-141°C (155-286°F), allowing flexible selection of glass bulb elements corresponding to the temperature of the site environment (such as high-temperature areas like kitchens and equipment rooms). This design prevents false activation in daily environments while ensuring precise response when a fire occurs.
 

Functional Positioning: Pendent Design + Fire-Fighting Specialization, Adaptable to Multiple Building Types


As a pendant sprinkler head, it can be directly installed under the ceiling. Combined with the gear-shaped deflector, it evenly covers the area below after water discharge. Its flow and water distribution performance are specifically designed for fire-fighting scenarios — once activated, it can quickly suppress initial fires, while linking with the fire protection system to achieve automated protection such as alarm and water replenishment.

Currently, this product has been widely applied in the fire pipelines of shopping malls, office buildings, residential buildings, etc., and can be directly adapted to standard fire engineering without customization.
 

Domestic Quality: Compliance Assurance, Stable and Reliable


Produced in China, this Spark sprinkler head meets relevant fire equipment standards. Its brass material and multi-temperature zone design balance durability and scenario adaptability, making it a representative equipment with "high cost-effectiveness + high reliability" in current building fire protection systems.

【Usage Tip】When installing, match the temperature-sensing element corresponding to the site temperature. Keep the deflector unobstructed in daily use to ensure response efficiency in emergency situations.
