Ultra-fine dry powder nozzle with adjustable spray angle

Abstract

The present invention proposes an ultra-fine dry powder nozzle with an adjustable spray angle, comprising: a connecting seat, the connecting seat is provided with a collecting pipe joint and a nozzle joint, the nozzle joint is connected with a fire-fighting nozzle, and the fire-fighting nozzle A sliding sleeve is arranged on the outside, and a locking device is arranged between the sliding sleeve and the fire nozzle. The ultra-fine dry powder spray head with adjustable spray angle of the present invention can adjust its spray angle and change its ultra-fine dry powder spray coverage, so that equipment with different volumes in the protection zone can be within the spray coverage of the relevant fire extinguishing agent spray head, The fire extinguishing speed of the related superfine dry powder fire extinguishing system is improved.

Description

technical field [0001] The invention belongs to the field of fire-fighting equipment, and in particular relates to an ultra-fine dry powder nozzle with adjustable spray angle. Background technique [0002] The current ultra-fine dry powder fire extinguishing system uses a fixed pipe network to protect the protection area. The pipe network of the fire extinguishing system is evenly equipped with ultra-fine dry powder nozzles. For fire extinguishing, since the direct injection coverage of the existing ultra-fine dry powder nozzles cannot be adjusted, the spray range is very fixed. Because the size and height of the equipment in the protection area are different, especially for larger equipment, the corresponding single nozzle It is difficult to completely cover each device with the direct injection range. When the parts of the equipment beyond the spray coverage of the nozzle catch fire, the fire can only be extinguished by the diffusion of the ultra-fine dry powder fire extin...

[0002] The current ultra-fine dry powder fire extinguishing system uses a fixed pipe network to protect the protection area. The pipe network of the fire extinguishing system is evenly equipped with ultra-fine dry powder nozzles. For fire extinguishing, since the direct injection coverage of the existing ultra-fine dry powder nozzles cannot be adjusted, the spray range is very fixed. Because the size and height of the equipment in the protection area are different, especially for larger equipment, the corresponding single nozzle It is difficult to completely cover each device with the direct injection range. When the parts of the equipment beyond the spray coverage of the nozzle catch fire, the fire can only be extinguished by the diffusion of the ultra-fine dry powder fire extinguishing agent sprayed from the nozzle, and the fire extinguishing speed is relatively slow.

If all nozzles with a larger spray coverage are used, for smaller equipment, the dry powder fire extinguishing agent that can be sprayed is relatively thin, and the fire extinguishing effect is poor.
