Hot New Products 5mm 141℃ Bulb - 5mm Special response sprinkler bulbs – Zhurong

A glass sprinkler bulb is the most reliable and economic device used to actuate a fire sprinkler head. The frangible bulb is simple to use, comprising a small thermo bulb made of glass containing a chemical liquid that will expand rapidly when exposed to rising temperatures, bursting the glass fire bulb at an accurately pre-determined temperature, thereby activating the sprinkler.

The temperature sensing glass ball is a temperature sensing release element used for automatic sprinkler heads, smoke vents, fire dampers and other release devices. The sealing liquid (G or F type) in the glass ball expands with the increase of temperature, and decomposes the ball into small pieces at the predetermined release temperature. The combination of unique bone shape design and special liquid is the decisive factor for the thermal response performance and strength of the temperature sensing glass ball. All main product features of temperature sensing glass ball can be obtained from the above chart.
The development of fire sprinkler design requires that glass spheres have low response time and high strength characteristics. In order to meet the demand for high quality and high technology related to life safety products, Menhai has established a professional research and development team to continuously improve the quality and performance of temperature sensitive glass balls.
With its unique bone shape design, the reinforced end can absorb the load from the mounting bracket, and introduce these loads into the sphere with reduced diameter along the axis, thus avoiding inappropriate shear and bending stress in the glass. In addition, the stress distribution of the glass ball allows the use of a lightweight structure, which, in combination with a special expansion liquid, can provide a very fast response time. Because of these characteristics, Menhai has become a global supplier of glass balls.

My company’s main fire products are: sprinkler head, spray head, water curtain sprinkler head, foam sprinkler head, early suppression quick response sprinkler head, quick response sprinkler head, glass ball sprinkler head, hidden sprinkler head, fusible alloy sprinkler head, and so on.
