Ultrafine dry powder nozzle capable of adjusting spraying angle

Abstract

The invention proposes a ultrafine dry powder nozzle capable of adjusting a spraying angle. The ultrafine dry powder nozzle comprises a connecting base; the connecting base is provided with a current collecting pipeline joint and a nozzle joint; the nozzle joint is connected with a fire control nozzle; a slide sleeve is arranged on the outer side of the fire control nozzle; and a locking device is arranged between the slide sleeve and the fire control nozzle. The ultrafine dry powder nozzle capable of adjusting the spraying angle can adjust the spraying angle and change a ultrafine dry powder spraying coverage range, can enable equipment with different sizes in a protecting area to locate in the spraying coverage range of related fire extinguishing agent nozzles, and accelerates the fire extinguishing speed of related ultrafine dry powder fire extinguishing systems.

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.
