ESFR Fire Sprinkler
The early suppression quick response nozzle has a large flow coefficient and a specially designed splash plate, which enables the nozzle to spray large-diameter, high-energy water droplets and form a spherical water flow below it. Hot air can penetrate the flame at the same time and directly cool the combustion body, so this nozzle has special advantages for protecting high-stack and high-shelf warehouses.
How To Working
The early suppression and quick response nozzle is mainly composed of frame, sealing element, ball seat, spring, action mechanism, fusible alloy sheet, screw, splash plate, etc.; the nozzle uses welded fusible element as the action element, and is composed of two identical connections The parts are connected through the welding layer of the fusible element. When the action temperature is reached, the welding layer melts, the connecting parts are separated, and the nozzle starts to spray water to extinguish the fire.
Usually, the early suppression and quick response sprinklers will generate a lot of mechanical pressure on the operating elements when they are under the working load. This series of sprinklers adopts the principle of leverage to reduce the force acting on the operating elements. For the sprinklers with this structure, the mechanical pressure is controlled. It is decomposed into the force on the support rod, the mechanical force of the fusible joint and the load of the flux between the fusible joint parts, so that the force on the flux is lower, and the composition of the flux required to reach the action temperature can be avoided at high temperature. Cold flow under stress.
