Special Features

  • Quick response mechanism: 3mm glass bubble sensing element combined with fusible alloy welded cover plate
  • High temperature resistant design: automatically opens when the temperature reaches 68 ℃, achieving efficient fire extinguishing response
  • Standard interface pressure: 1/2 "NPT (DN15) standard thread, supporting a working pressure of 1.2MPa, suitable for various fire pipeline systems
  • Accurate hydraulic performance: The K80 flow coefficient has been rigorously calibrated to ensure optimal spray density and range in the coverage area
  • Double trigger protection: First, the melting alloy cover plate falls off to start the nozzle descent, and then the glass bubble ruptures due to heat to open the water circuit, with a dual safety design

Description

Model Number: DN15 K80 68 degrees
Material: Copper
Type: Canceled fire sprinkler head
Action temperature: 68 ° C
Thread size: 1/2 NPT, DN15
Glass bubble diameter: 3mm
Flow coefficient K: K80
Maximum working pressure: 1.2MPa
Working principle:The outer cover and the outer cover (decorative cover) are welded together using a fusible alloy. When the fire occurs, the ambient temperature rises and reaches the melting point of the fusible alloy. The outer cover (decorative cover) automatically falls off, and the sprinkler plate moves down. As the temperature continues to rise, the glass ball nozzle inside the cover is temperature. Sensitive, the liquid expands and breaks, thus opening the nozzle to automatically spray water.
