  vinking fire sprinkler

 

Product Description

 1.Declare:

Glass ball closed sprinkle nozzle is the most key components of automatic sprinkler system, used to detect the instrument of fire element,And to control fire and extinguish firethrough the automatic water spray device. Apply to work environment temperature less than 4 ºC, and is not higher than 70 ºC in light of the danger level buildings as wet system to fight fire water of the hotel, department stores, restaurants, entertainment, warehouse, hospitals, factories, the airport and the basement automatic sprinkler system such as the pipe network.

 

2.Principle of operation:

This series of ball sprinkler head working principle is filled with high thermal expansion coefficient of organic solution of the glass ball as a heat sensitive components. At normal temperature, and the glass ball shell we can withstand the support, ensure wards of the seal. When the fire breaks out temperature, glass ball inside the organic solution happen and generates a lot of thermal pressure inside, until the glass ball shell happen broken, and open water spray nozzle.

 

3.Structure characteristics:

This series of ball sprinkle nozzle is made of copper alloy frame, glass ball, seal, glass ball seat, tight set screws and splash water dish wait for assembly and into. Compact structure, shape exquisite and beautiful

3.1, Nozzle framework USES the high strength copper alloy precision forging, high strength,corrosion resistance.

3.2, Temperature temperature sensing elements (ball) with high quality products at home and abroad, glass ball high strength, reliable, and reaction speed.

3.2, Temperature temperature sensing elements (ball) with high quality products at home and abroad, glass ball high strength, reliable, and reaction speed.

 

4, technical characteristics and types and specifications:

4.1, nominal diameter: φ 15 mm, connected to thread: R1/2 ", the flow characteristic factor: K = 80 ± 4.

4.2, nominal diameter: φ 20 mm, connected to thread: R3/4 ", the flow characteristic factor: K = 115 ± 9.

4.3, rated pressure: 1.2 Mpa(12 Bars), The factory test pressure: 3.0 Mpa(30Bars).

4.4, glass ball diameter: φ 3 mm, φ 5 mm.
