Description
Technical field
The utility model relates to the fire-fighting technique field of components, relates to a kind of Dust-proof nozzle specifically.
Background technology
Extinction using gas is applied to the ship of war and aircraft the earliest in China, and development has also obtained broad development at civil area so far.Along with the development of extinction using gas technology, nozzle has determined the effect of fire extinguishing as the key position that spurts; Existing nozzle comprises nozzle body; The nozzle body rear end is provided with open trough, is circumferentially with several through holes on the edge, outer surface middle part of nozzle body, and each through hole all communicates with open trough.During use; The nozzle body rear end is connected with pipeline on the gas extinguishing system gets final product; Extinguishing chemical sprays through the through hole from nozzle behind container value, tube connector, liquid check valve and the pipeline of fire extinguishing system successively; When but existing this nozzle used in the occasion that a large amount of dust and other impurities are arranged, foreign matters such as these dusts hindered the normal fire-fighting work of nozzle easily with spray nozzle clogging.
The utility model content
The purpose of the utility model provides a kind of Dust-proof nozzle, it can carry out fire-fighting work reliably smoothly and can not produce clogging in the environment of dust is arranged, and has improved the reliability of fire extinguishing, and it is simple in structure, handling ease, low cost of manufacture.
In order to realize such scheme, the technical solution of the utility model is: a kind of Dust-proof nozzle comprises nozzle body; The rear end of said nozzle body is provided with open trough; The middle part of said nozzle body is along being circumferentially with several through holes, and each said through hole all communicates with said open trough, wherein also comprises back-up ring, spring and piston; Said back-up ring is installed in the open trough and is positioned at the rear of each said through hole; Said spring is installed on the front end in the open trough, and said piston is installed between back-up ring and the spring, and said piston and open trough fit tightly.
The utility model Dust-proof nozzle, wherein said back-up ring is selected circlip for use.
The utility model Dust-proof nozzle, the wall of wherein said open trough is provided with internal thread.
After adopting such scheme, the utility model Dust-proof nozzle can play spacing piston through in the open trough of nozzle body, back-up ring being installed; After the pipeline of nozzle body rear end and fire extinguishing system was connected, extinguishing chemical got into from pipeline in the open trough of nozzle body, promotes piston advances forward; The piston forward against is compressed spring forward, up to each through hole on the nozzle body is all exposed; Extinguishing chemical stamps out a fire, after agent application is intact from each through hole ejection; Piston no longer receives thrust and the elastic force effect that receives spring is moved backward, is against up to piston rear end and returns to original position on the back-up ring, and each through hole on this moment nozzle body all is closed; This is simple in structure, and handling ease, low cost of manufacture are because Seal Design; Prevent the through hole of foreign matter plug nozzles such as dust, guaranteed the operate as normal of nozzle, improved the fire extinguishing reliability greatly.
Description of drawings
Fig. 1 is the rearview of the utility model Dust-proof nozzle;
Fig. 2 is that the A-A of Fig. 1 is to sectional structure chart.
The specific embodiment
As depicted in figs. 1 and 2, the utility model Dust-proof nozzle comprises nozzle body 1, circlip 4, spring 5 and piston 6, and the rear end of nozzle body 1 is processed with cylindrical open trough 2, is processed with internal thread 7 on the wall of open trough 2.The setting of internal thread 7 is to be convenient to the installation that is spirally connected of the pipeline of nozzle body 1 and fire extinguishing system; The middle part of nozzle body 1 is along circumferentially being processed with eight through holes 3; Each through hole 3 all communicates with open trough 2, and circlip 4 is installed in the annular groove 8 of processing in the open trough 2, and this annular groove 8 is positioned at the rear of each through hole 3; Select for use circlip 4 to be convenient to be installed in the annular groove 8, and promptly can in annular groove 8, not come out after installing.Spring 5 is installed on the front end in the open trough 2, and spring 5 is in the minute-pressure state that contracts, and piston 6 is installed between circlip 4 and the spring 5, and piston 6 and open trough 2 fit tightly.
Before not using, each through hole 3 of the utility model Dust-proof nozzle is all blocked by piston, and Dust-proof nozzle is in closed state; During use, get final product after the pipeline thread of the rear end of nozzle body 1 and fire extinguishing system connected, extinguishing chemical gets in the open trough 2 of nozzle body 1 from pipeline; Promoting piston 6 moves forward; Piston 6 promotes spring 5 forward, and spring 5 is compression forward gradually, moves to up to piston 6 eight through holes 3 are all exposed; Extinguishing chemical blows out from through hole 3, stamps out a fire; After agent application was intact, the elastic force through spring 5 promoted piston 6 and moves backward, was against the front surface of circlip 4 up to homing, and the utility model Dust-proof nozzle is in closed state again.
The utility model Dust-proof nozzle is simple in structure, handling ease, low cost of manufacture; Because Seal Design has prevented that foreign matter or dust from stopping up, and has improved the reliability of fire extinguishing greatly; Effectively solved the integrity problem that extinguishing chemical can spurt safely under the environment that big dust is arranged.
The above embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that the common engineers and technicians in this area make the technical scheme of the utility model all should fall in the protection domain that claims of the utility model confirm.
