Abstract
The utility model belongs to a fire extinguishing spray nozzle used for suspension type dry powder extinguishing equipment. The upper cavity of the spray nozzle is an upper tapered hole with a small upper part and a large lower part; the upper part of the lower cavity of the spray nozzle is a lower tapered hole which has a large upper part and a small lower part and is correspondingly connected with the upper tapered hole, and the lower part of the lower cavity is a vertical hole intersected with the bottom of the lower tapered hole; three-dimensional spray orifices are distributed at the periphery of the upper cavity of the spray nozzle at equal intervals and are all inclined holes inclining downwards from outside to inside, and the upper cavity of the spray nozzle is communicated with the inner cavity of a pressure tank. The three-dimensional spray orifices disturbs, impacts, shakes, cuts and grinds dry powder extinguishing agent particles which are refined in the inner cavity of the spray nozzle to form superfine dry powder and are then jet out from the spray orifices, thus extinguishing fire more effectively and quickly. The fire extinguishing spray nozzle used for the suspension type dry powder extinguishing equipment is simple in design and convenient and practical, and is relatively ideal and simple and practical.
Description
Technical field
The utility model belongs to a kind of parts of extinguishing device, specifically belongs to the fighting nozzle on a kind of hanged powder extinguishing equipment.
Background technology
In modern society,, need use extinguishing device in a lot of occasions from the consideration of safety factor, and because the reason of several factors make and can only use dry powder extinguisher in some occasions.In addition, because the dry-chemical fire extinguishing medium is easy to use, material obtains extensively and price possesses competitiveness, and become the firing-fighting medium of extensive use.These extinguishing devices that use powder extinguishing agent generally adopt pressure storage type or combustion type when fire extinguishing.
Because rapid, non-maintaining, adaptability that the combustion type fire extinguisher had obtain increasing use by force.The combustion type fire extinguisher mainly comprises at present: technology such as super-sonic dry-chemical fire extinguishing and pulsed dry-chemical fire extinguishing.Short action time but existing extinguishing device, especially combustion type extinguishing device exist to firing-fighting medium, so the refinement of fire-fighting powder is not thorough, thereby can't effectively suppress the inherent shortcoming of resume combustion.
Summary of the invention
For overcoming the defective of existing combustion type extinguishing device, the utility model proposes a kind of fighting nozzle that is used for hanged powder extinguishing equipment that can effectively put out a fire at short notice.
The structure of the utility model is such:
The utility model is a kind of fighting nozzle that is used for hanged powder extinguishing equipment, and fighting nozzle is installed in pressurized tank bottom central authorities, and nozzle chamber is made up of the nozzle epicoele and the nozzle cavity of resorption of up/down perforation.The nozzle epicoele is up-small and down-big upper conical hole; The nozzle cavity of resorption is made up of two parts: cavity of resorption top is the corresponding up big and down small inferior pyramidal hole that joins with the upper conical hole, and the upright opening that the cavity of resorption bottom is and intersect inferior pyramidal hole bottom, upright opening are the cylindrical holes that communicate with the external world.Upper conical hole top central authorities be one with the last hole of pressurized tank intracavity inter-connection, it is relative with described upright opening.Around the nozzle epicoele, be arranged with three-dimensional spray orifice equidistantly, three-dimensional spray orifice is downward-sloping from outside to inside inclined hole, with nozzle epicoele and pressurized tank intracavity inter-connection.
The utility model adopts the biconial inner chamber and adopts three-dimensional inclined hole structure; Air-flow is ground dry powder in a plurality of directions; And utilize the CFD simulation analysis of computer; Angle, size to spray orifice are optimized, and make the powder extinguishing agent refinement form ultra-fine dry powder, can stamp out the flames more effectively and quickly.The utility model simplicity of design, convenient and practical, be a comparatively ideal simple and practical fire-extinguishing apparatus.

Among the figure:
1 pressurized tank, gas generating agent chambers 2,3 powder extinguishing agents, 4 nozzles, on 41 the hole, 42 three-dimensional spray orifices, 43 upper conical holes, 44-1 inferior pyramidal hole, 44-2 upright opening, 45 flanges.
The specific embodiment
Referring to Fig. 1-Fig. 5, the utility model is a kind of fighting nozzle that is used for hanged powder extinguishing equipment.Dry powder extinguishing installation mainly is made up of pressurized tank 1, gas generating agent chamber 2, powder extinguishing agent 3 and nozzle 4.Pressurized tank 1 and gas generating agent chamber 2 are cylindric, and gas generating agent chamber 2 is placed in the middle of the pressurized tank 1, and powder extinguishing agent 3 is filled in the pressurized tank inner chamber between pressurized tank 1 and the gas generating agent chamber 2.
The utility model fighting nozzle is installed in pressurized tank 1 bottom central authorities, and nozzle chamber is made up of the nozzle epicoele and the nozzle cavity of resorption of up/down perforation.The nozzle epicoele is up-small and down-big upper conical hole 43; The nozzle cavity of resorption is made up of two parts: cavity of resorption top for and the upper conical hole 43 corresponding up big and down small inferior pyramidal hole 44-1 that join, the upright opening 44-2 that the cavity of resorption bottom be and intersect inferior pyramidal hole 44-1 bottom, upright opening 44-2 are the cylindrical holes that communicate with the external world.Inferior pyramidal hole 44-1 and upright opening 44-2 are combined into spray-hole.Upper conical hole 43 top central authorities be one with the last hole 41 of pressurized tank 1 intracavity inter-connection, it is relative with described upright opening 44-2.Around the nozzle epicoele, be arranged with three-dimensional spray orifice 42 equidistantly, three-dimensional spray orifice 42 is 3-8, the extinguishing device of common size is preferably 4.Three-dimensional spray orifice 42 is downward-sloping from outside to inside inclined hole, with nozzle epicoele and pressurized tank 1 intracavity inter-connection.
Shown in Figure 1 is the fundamental diagram of extinguishing device; The gases at high pressure that 2 self-contained gas generating agents produce through the gas generating agent chamber get in the pressurized tank 1; Stir a jar interior powder extinguishing agent 3 of filling,, the powder extinguishing agent particle is carried out disturbance, impact, concussion, cutting, grinding through the utlity model has the three-dimensional nozzle 42 of inclination form; In nozzle chamber, formed ultra-fine dry powder by refinement; Eject by spray-hole at last, and wrap up in taking and directly spray to protected object, improve extinguishing property with the mode of gas-solid biphase flow by the dry powder of refinement.
The utility model is used simulation analysis of computer, and the size and the angle of inclination in each aperture of the extinguishing device of different sizes, different purposes is optimized calculating, makes the flow field of spray orifice of nozzle best, optimize to the grinding refinement of dry powder with spray the disturbance effect.
