Abstract
The utility model discloses a rotary type spray fire extinguishing device which comprises a liquid inlet stand pipe body with a passage, an upper end cover, a lower end cover and a cone-shaped flow control tongue on the lower end cover, wherein the liquid inlet stand pipe body adopts a stepped connecting pipe and is sequentially sleeved by an oil-free end face bearing and an oil-free axial surface bearing; the upper end cover is sleeved outside both the oil-free end face bearing and the oil-free axial surface bearing, and a gap is formed between the oil-free end face bearing and the upper end cover; a seam allowance sealing mechanism is arranged in the gap; the flow control tongue is positioned in the overflow passage; a spring is arranged between the flow control tongue and the lower end cover; one end of the spring is fixed on the flow control tongue, and the other end is fixed on the lower end cover; and a spray port is formed on the side wall of the lower end cover. The rotary type spray fire extinguishing device has the advantages of reasonable structure, flexible operation and long service life.
Description
Technical field
The utility model relates to a kind of extinguishing device, particularly a kind of rotary spray extinguishing device.
Background technology
The fire extinguishing sprayer that is using on the market now has the centrifugal rotation shower nozzle, rotary screen type big-flow fire extinguishing sprayer of old-fashioned temperature-sensitive automatic sprinkler, open type etc.The temperature-sensitive automatic sprinkler is to utilize heat-resisting 68 ℃ glass vacuole to absorb the temperature of fire combustion-gas flow, and making begins to explode when expansion of liquids reaches critical point in the vacuole opens the valve plug sprinkling fire, and its shortcoming is that the time of vacuole blast significantly lags behind fire; The deadly defect of the centrifugal energy nozzle of open type is, two side-thrust spout moments of torsion of its centrifugal energy nozzle are very little, in addition water stain corrosion to the part that is rotatably assorted, in case do not turn the function that has just lost the sheet fire extinguishing, its spray radius is little in addition, the layout density of shower nozzle is large, is difficult for again arranging installation and fixing, and construction costs is high; Rotary screen type big-flow fire extinguishing sprayer, formed by base, support, current divider, bearing wheel axle bed, minute water wheels, swirl vane, but its structure and runner design are complicated, and hydraulic loss is large, and spray liquid intensity, flow are restive, without sealing, liquid or impurity enter bearing body, produce abrasion and corrosion to bearing, adopt rolling bearing, stuck phenomenon can appear in easy-to-rust.
Summary of the invention
It is a kind of rational in infrastructure that the purpose of this utility model just is to provide, and work is flexible, the rotary spray extinguishing device of long service life.
To achieve these goals, the technical solution adopted in the utility model is such: rotary spray extinguishing device of the present utility model, comprise the feed liquor standpipe body with flow channels, upper end cover, bottom end cover and taper flow-control tongue, the flow-control tongue is arranged on the bottom end cover, described feed liquor standpipe body is step-like tube connector, be socketed successively on the feed liquor standpipe body one without oily end face bearing and without oily axial plane bearing, described upper end cover is socketed in without oily axial plane bearing with without the oily end face bearing outside, and and without leaving the gap between the oily end face bearing, in the gap, be provided with the seam sealing mechanism, described flow-control tongue is positioned at flow channels, be provided with spring between flow-control tongue and the bottom end cover, spring one end is fixed on the flow-control tongue, and an end is fixed on the bottom end cover, and the bottom end cover sidewall offers mouth spray.
As preferably, described seam sealing mechanism is comprised of seam axial plane seal and sealed briquette, and seam axial plane seal is fixed in the described gap by sealed briquette.
As preferably, described bottom end cover and upper end cover clamping.
Compared with prior art, the utility model has the advantage of: the utility model is rational in infrastructure, flexible working mode, can regulate as required the spray scope, avoid causing waste, the bottom end cover side has mouth spray, and liquid sprays out radially to diffuse the even impelling of mode from mouth spray under the effect of pressure and rotary centrifugal force; Adopt the seam sealing mechanism to prevent that liquid or impurity from entering bearing body, produce abrasion and corrosion to bearing, the service life of extension fixture; Adopt without oily axial plane bearing, without oily end face bearing, decrease fretting wear, also not water funk punching and other acid solution etch and wash away, overcome the bearing easy-to-rust of other rotary nozzles uses, stuck phenomenon appears; After the work, the flow-control tongue is blocked flow channels, prevents liquid corrosion the utility model, prolongs its service life; The seam sealing mechanism is comprised of seam axial plane seal and sealed briquette, good sealing effect; Bottom end cover and upper end cover clamping avoid the utility model to produce between the end cap in rotary course loosening.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1, rotary spray extinguishing device of the present utility model, comprise the feed liquor standpipe body 1 with flow channels, upper end cover 2, bottom end cover 3 and taper flow-control tongue 7, flow-control tongue 7 is arranged on the bottom end cover 3, described feed liquor standpipe body 1 is step-like tube connector, be socketed successively on the feed liquor standpipe body 1 one without oily end face bearing 4 and without oily axial plane bearing 5, described upper end cover 2 is socketed in without oily axial plane bearing 5 with without oily end face bearing 4 outsides, and and without leaving the gap between the oily end face bearing 4, in the gap, be provided with seam sealing mechanism 6, described flow-control tongue 7 is positioned at flow channels, be provided with spring 8 between flow-control tongue 7 and the bottom end cover 3, spring 8 one ends are fixed on the flow-control tongue 7, one end is fixed on the bottom end cover 3, and bottom end cover 3 sidewalls offer mouth spray 9, and described seam sealing mechanism 6 is comprised of seam axial plane seal and sealed briquette, seam axial plane seal is fixed in the described gap by sealed briquette, described bottom end cover 3 and upper end cover 2 clampings.
During work, water enters feed liquor standpipe body 1 through flow channels, because have mouth spray 9 on the bottom end cover 3, water is evenly sprayed by mouth spray 9 under the effect of flow-control tongue 7, simultaneously, bottom end cover 3 is subject to a reverse stamping press of water, bottom end cover 3 is rotated motion under acting on without oily end face bearing 4, the centrifugal force that bottom end cover 3 rotations produce becomes parabolical to eject in the water of mouth spray 9 ejections, and hydraulic pressure is larger, the scope of spraying is just larger, reaches the effect of quick sprinkling fire-distinguishing.After the work, flow-control tongue 7 is blocked flow channels by the elastic force of spring 8, prevents liquid corrosion the utility model, prolongs its service life.
