Title:
A ROTARY TEMPERATURE SENSITIVE SPRINKLER FIRE EXTINGUISHING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2006/114024
Kind Code:
A1
Abstract:
A rotary temperature sensitive sprinkler fire extinguishing apparatus, comprises induction pipe and water nozzle body. The water nozzle body consists of water nozzle cover and water nozzle. A stop valve core, the upper end of which is a stop valve, is mounted inside the water nozzle body. A supporting rack is mounted at the lower end of the water nozzle. A glass heat sensitive element is uprightly mounted in the supporting rack. The one end of the glass heat sensitive element is insert in the adjusting screw of the supporting rack, the other end props up the lower end of the stop valve core. While firing, the glass heat sensitive element can automatically rupture, the stop valve core, which is supported by the glass heat sensitive element, falls down to make the stop valve leave the water inlet, which is situated at the lower end of the induction pipe. Then water is immediately entered the chamber and spurted out from the outlet. At the same time, a reverse impulsive force is applied to the water nozzle body to make it rotate through the ball bearing. The centrifugal force produced by the rotation of the nozzle body, makes water form parabolical eject, so as to achieve bigger area fire extinguishing effect.
