SPECIFICATION:

The screw-type water spray is designed to prevent spreading of underground fires and eliminate ignition sources in horizontal, inclined and vertical workings.

The water spray can be fixed directly in the mine working, on the car board, or ropes with a diameter from 10 to 40 mm. When extinguishing a fire in horizontal and inclined workings, the unit is located on the return air side. In vertical workings, the unit is attached to the rope and lowered to the fire seat. The fire suppression efficiency is higher than in horizontal workings. The depth is limited to the strength of the hose line. Fire is suppressed with water sprayed with two screw-type nozzles. The nozzles are located one above the other, with the lower one extended forward. This reduces the mutual influence of the upper and lower spray cones.

The water spray can work together with the KM lock and release valve. This ensures operation of the unit in the automatic mode. When the temperature in the control zone rises to 68 ° C, the water spray runs automatically.
