Sprinkler flush sprinkler head
Sprinkler equipment is an automated fire extinguishing device to extinguish fire quickly. Since it minimizes the damages to citizens and properties. it should guarantee the best credit at the worst conditions.
To fulfill this purpose and lead the creative technological innovation in fire extinguishment business, a flush sprinkler developed by Asia Union adopts the 8 ball points support using 8 stainless bearing balls 3.2mm in diameter; the head has a simple struction which eliminated the existing problems.
Therefore, Wonjin’s head secured the internal properties such as impact resistance or water leakage resistance and was designed to have small and elegant shape.
Internal impact type sprinkler head is the first safe sprinkler head ever.
Forms an impact-resistant structure by steel ball support
Wonkin Metal introduced O-Ring made of teflon, which is highly durable, on a nozzle. Moreover, since the side of O-Ring inside nozzle was coated, the product can offer a perfect sealing and smooth operation in any problems.
Forms an impact-resistant structure by steel ball support
The product adopts a support method with 8 steel balls; it is greatly impact-resistant, and the problem of damage or leakage due to external impact got essentially solved.
Low assembly load
The assembly load was minimized due to sealing method by O-ring. As a result, the stress inside a head is very small and the design is safe.
Design that fits the exterior appearance
Because the product is usually installed indoors, the head and the exposed part of thermal sensing board were designed to be smaller considering the appearance after installation. The exterior design of exposed part was also taken into account.
Structure
Wonjin’s sprinkler head adopts 8 ball points method which requires 8 3.2mm wide stainless bearing balls. The head has a simple structure that solved the existing problems.
Therefore the head of Wonjin was able to secure impact-resistance, leakage-resistant, and other durability properties, and to get a small but elegant design.
Wonjin’s impact-resistant sprinkler head is greatly safe sprinkler head.
Order of operation
1. A head, with the assembly weight lightened by balls on disassembly part, is usually attached on fuse metal by compressive force.
2. When heat from fire is detected, the fuse metal melts, goes in, and begins disassembly. The assembly weight declines and disappears, and the power of spring activates disassembly.
3. The valve, disassembled by spring power, gets buried inside of deflector. And the deflector falls by water pressure.
4. The deflector reaches the lower part of frame, and the fire fighting water spouts from the nozzle.
Specification
Wonjin flush sprinkler head adopted 「high quality special coating and O-ring, 8 bearing balls on disassembly part」 on the nozzle, and is a product with completely new structure.
This sprinkler head is quite durable unless the sprinkler head is activated by temperature and its disassembly part gets disassembled completely, or the head itself is destroyed.
Its stable structure was developed by Wonjin Metal, and it is a impact-resistant sprinkler head that literally endures impact.

Assembly drawing
Glass bulb sprinkler head
A frame type sprinkler head with a glass bulb assembed
The thermal sensing part of glass bulb is made by filling special glass with heat expansion fluid. The head is suitable for exposed piping on ceiling in spaces such as a parking lot.
Wonjin’s glass bulb sprinkler head has a minimized and light structure and adopted a glass bulb of Job, the world-largest glass bulb manufacturer that seldom causes malfunctions, to guarantee safety and trust.
