Fire extinguishing agent spray head for gas fire extinguishing system

Abstract

The invention relates to the technical field of fire extinguishing agents, and discloses a fire extinguishing agent spray head for a gas fire extinguishing system. The fire extinguishing agent spray head comprises a spray pipe, wherein one end of the spray pipe is fixedly connected with a spray nozzle; the spray nozzle communicates with the spray pipe; a plurality of U-shaped gas conveying holes are annularly and uniformly formed in the pipe wall of the spray pipe at equal distance; a piston is in sliding connection in the spray pipe; one end, away from the spray nozzle, of the piston is equipped with a threaded slot; a threaded rod is in threaded connection in the threaded slot; a worm gear fixedly sleeves the rod wall, outside the threaded slot, of the threaded rod; a worm is rotatably connected on the pipe wall of the spray pipe through two sealing bearings; and the worm is engaged with the worm gear; and the upper end of the worm passes through the sealing bearings and extends outwards. The fire extinguishing agent spray head for the gas fire extinguishing system can prevent the spray pipe from being blocked as impurities such as dust easily enter the spray pipe when the sprayhead is idle, and avoids the condition that the fire extinguishing agent cannot be used as gas conveying of the fire extinguishing agent is affected.

Description

technical field [0001] The invention relates to the field of fire extinguishing agent technology, in particular to a fire extinguishing agent nozzle used in a gas fire extinguishing system. Background technique [0002] The gas fire extinguishing system includes a storage bottle group, a high-pressure hose, a manifold, multiple fire extinguishing agent nozzles arranged in the protection area and an automatic fire extinguishing controller. The fire extinguishing mechanism of the gas fire extinguishing agent is divided into two types: chemical action and physical action. The role lies in the active free radicals in the inert flame, inhibiting the chemical reaction of combustion, interrupting the chain reaction of combustion, and quickly extinguishing the fire. The physical effect is to reduce the concentration of oxygen in the smelting zone, so that the oxygen concentration is lower than the minimum value required to maintain smelting. The fire will suffocate and extinguish th...
