Abstract
The utility model relates to a drip-proof spray head device for high pressure fine water mists. The drip-proof spray head device consists of a piston rod (1), a spring (2), a drip-proof check valve (3), a filter net (4), a micro spray nozzle (5) and a spray head (6), and is characterized in that the piston rod (1) and the spring (2) are arranged in the drip-proof check calve (3); the spring (2) is arranged on the piston rod (1); the filter net (4) and the micro spray nozzle (5) are arranged on the spray nozzle (6); and the spray head (6) is connected with the drip-proof check valve (3) by threads. The drip-proof spray head device disclosed by the utility model protects equipment from secondary damage by an automatic fire-extinguishing system after a fire hazard happens; the drip-proof check calve is additionally arranged at the front end of the special-purpose high pressure fine water mist spray head to prevent residual water of a pipeline from dripping into a protective region along the spray head after work of a high pressure fine water mist automatic fire-extinguishing system is completed.
Description
Technical field
The utility model relates to a kind of ejecting device, relates to the drip-proof ejecting device of a kind of heavy pressure fine spray band.
Background technology
Present shower nozzle is comprised of nozzle body, nozzle carrier, nozzle, guiding device and filter screen, under certain hydraulic pressure, utilize the mechanical systems such as centrifugal, shock, jet to make water fogging, once but duty stops, pipeline pressure can decline, and the water of pipeline residual will form water droplet, in shower nozzle splashes into guard plot, precision instrument and important archives are caused damage.
Summary of the invention
The utility model object is to overcome prior art deficiency and provides a kind of for protection equipment is after breaking out of fire, by automatic fire extinguishing system, is not caused the drip-proof ejecting device of heavy pressure fine spray band of secondary damage.For achieving the above object, the utility model has adopted following technical scheme: the drip-proof ejecting device of a kind of heavy pressure fine spray band, it is by piston rod (1), spring (2), drip-proof check valve (3), screen pack (4), micro nozzle (5), shower nozzle (6) forms, it is characterized in that: piston rod (1), spring (2) is arranged in drip-proof check valve (3), spring (2) is arranged on piston rod (1), screen pack (4), micro nozzle (5) is arranged on shower nozzle (6), shower nozzle (6) is threaded connection with drip-proof check valve (3).
The utility model has protected equipment after breaking out of fire; by automatic fire extinguishing system, do not caused secondary damage; at the nozzle specially used front end of heavy pressure fine spray, add drip-proof check valve, prevent that, after high-pressure water mist automatic fire extinguishing system end-of-job, pipeline residual water splashes into guard plot along shower nozzle.
accompanying drawing explanation:
Fig. 1 is the utility model structural representation
the specific embodiment:
The drip-proof ejecting device of a kind of heavy pressure fine spray band, it is comprised of piston rod (1), spring (2), drip-proof check valve (3), screen pack (4), micro nozzle (5), shower nozzle (6), it is characterized in that: piston rod (1), spring (2) are arranged in drip-proof check valve (3), spring (2) is arranged on piston rod (1), it is upper that screen pack (4), micro nozzle (5) are arranged on shower nozzle (6), shower nozzle 6) be threaded connection with drip-proof check valve (3).
Because the nozzle specially used front end of heavy pressure fine spray adds drip-proof check valve, prevent that, after high-pressure water mist automatic fire extinguishing system end-of-job, pipeline residual water splashes into guard plot along shower nozzle.
