Abstract

The invention discloses an extinguishing agent nozzle for a gas fire-extinguishing system, which consists of a nozzle body, a clamp ring and a protective atomizing cover, wherein the protective atomizing cover consists of a circular ring body and a curved arc body which is extended along the edge of the circular ring body; the outer surface of the nozzle body consists of a nut section with the largest diameter, a cone frustum and a cylindrical section which is positioned between the nut section and the cone frustum; the cylindrical section of the nozzle body close to the nut section is provided with an external thread which is matched with the clamp ring; the nozzle body is provided with a nozzle hollow cavity; the cylindrical section of the nozzle body is provided with more than three uniformly distributed spray holes; the side wall of the cone frustum is provided with more than four uniformly distributed oblique spray holes; and the nozzle hollow cavity positioned on upper parts of the spray holes is provided with an internal thread which is matched with a collecting pipe. When a mounting body of a protected area of the gas fire-extinguishing system is provided with the extinguishing agent nozzle for the gas fire-extinguishing system, the adjustable range of the flow and the flow rate of an extinguishing agent can be increased; the assembly shape is more beautiful; the atomization rate of the extinguishing agent is improved; and the extinguishing effect is strengthened.

Description

technical field

[0001] The invention relates to a fire extinguishing agent nozzle of 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, and the fire will suffocate and extinguish the fire due to the loss of sufficient oxygen support. The fire extin...
