Abstract
The utility model belongs to the technical field of fire protection. A cylindrical rotational flow body with two plates crossed is arranged in the cavity of a nozzle body by the utility model. When mixed liquor flows out of a spout at the right end of the nozzle body, because of high speed and rotation, certain negative pressure is generated at periphery of a water flow, air passes through holes on a suction hood of a front wall board and sucked in a foam output tube together with fluid water droplets for foaming to achieve the purpose of effectively extinguishing fire at a high speed. The utility model can be installed vertically.
Description
Affiliated technical field
The utility model belongs to the fire prevention field, relates to a kind of foam maker.
Background technology
Existing fire-fighting fire extinguishing foam maker, coefficient of foaming is low, and fire-fighting efficiency is low, speed is slow and the mounting structure complexity, the needs in the time of can't satisfying fire extinguishing fast.
Summary of the invention:
The utility model provides a kind of novel coefficient of foaming height, and the fire-fighting efficiency height, speed is fast, cost is low, the vertical foam maker of the simple many suction holes spiral-flow type of mounting structure.
The scheme that its technical problem that solves the utility model adopts is: foam mixing liquid is by the mixed liquor input pipe, enter into nozzle body, the cylindrical rotary fluid that one two plate intersects is housed in the nozzle body cavity, when mixed liquor mass flowing nozzle body right-hand member spout, because speed is high and rotation, produce certain negative pressure around the current, making ambient air together be drawn into the foam efferent duct by the hole on front panel and the air-suction cover with the fluid water droplet foams, foam mixing liquid after the foaming sprays to the fire protection scene by foam emission guider, reaches at a high speed the effectively purpose of fire extinguishing.
The beneficial effects of the utility model are, vertical installation, and rotation at a high speed behind the foam solution mass flowing nozzle body, atomizing effect is good, the coefficient of foaming height of foam solution.
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is a profile of the present utility model.
1. import adpting flanges among the figure, 2. mixed liquor input pipe, 3. front panel, 4. rotary fluid, 5. nozzle body, 6. air-suction cover, 7. foam efferent duct, 8. outlet adpting flange.
The working condition of the concrete device that the utility model proposes below in conjunction with description of drawings.
Mixed liquor input pipe (2) is 90 ° of bend pipes, and the lower end of mixed liquor input pipe (2) is welded with import adpting flange (1); The bend pipe right-hand member of mixed liquor input pipe (2) has front panel (3), and front panel (3) is the garden plate of a porous; Nozzle body (5) is connected with mixed liquor input pipe (2) by screw thread, in nozzle body (5) lining rotary fluid (4) is arranged, and rotary fluid (4) is cylindrical that two plates intersect; Air-suction cover (6) the whole body all is the hole; Foam mixing liquid enters into nozzle body (5) by mixed liquor input pipe (2), behind the rotary fluid (4) in nozzle body (5) chamber, during mixed liquor mass flowing nozzle body (5) right-hand member spout, because speed is high and rotation, produce certain negative pressure around the current, making ambient air pass through hole on front panel (3), the air-suction cover (6) together is drawn into foam efferent duct (7) with the fluid water droplet and foams, foam mixing liquid after the foaming sprays to the fire protection scene by the emission guider, reaches at a high speed effectively fire extinguishing purpose.
Mixed liquor makes mixing material become the fluid of high-voltage high-speed rotation through rotary fluid (4), and when mass flowing nozzle body (5), under the effect of high-voltage high-speed rotation, current produce the centrifugal atomizing effect, and water droplet becomes water smoke not of uniform size.Because under equal amount of liquid, through behind the centrifugal atomizing, water droplet quantity increases, surface area increases, thereby increase the mixture table area of air and foam mixing liquid, increased the combined amount of air in foam mixing liquid, improved the coefficient of foaming of foam solution.
The height of the mixing ratio of air and foam mixing liquid has relation of the utmost importance with the structure of foam maker, for the soakage that improves air with reduce air-breathing resistance, open the purpose that a plurality of holes reach many sucks by the percent opening and the front panel (3) that strengthen air-suction cover (6).
The utility model can vertically be installed.
Claims (3)
1. the vertical foam maker of suction hole spiral-flow type more than a kind, be by import adpting flange (1), mixed liquor input pipe (2), front panel (3), cylindrical rotary fluid (4), nozzle body (5), air-suction cover (6), foam efferent duct (7), outlet adpting flange (8) is formed, it is characterized in that: there is rotary fluid (4) nozzle body (5) lining, opens a plurality of holes on air-suction cover (6) and the front panel (3).
2. the vertical foam maker of many suction holes spiral-flow type according to claim 1 is characterized in that: rotary fluid (4) is the cylindrical of two plates intersection.
3. the vertical foam maker of many suction holes spiral-flow type according to claim 1 is characterized in that: vertical installation.
