Description
Technical field
The present invention relates to a kind of rotary nozzle mechanism, the centrifugal automatic rotary dispensing device of especially a kind of impelling.
Background technology
The fire extinguishing sprayer that is using on the market now has the centrifugal rotary 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, and are water stain in addition to the corrosion of part that is rotatably assorted, in case do not change the function that has just lost the sheet fire extinguishing; Its spray radius is little in addition; The layout density of shower nozzle is big, is difficult for being provided with installation and fixing again, and construction costs is high; Rotary screen type big-flow fire extinguishing sprayer is made up of base, support, current divider, bearing wheel axle bed, branch water wheels, swirl vane, but its structure and runner complex design; Hydraulic loss is big, and spray liquid intensity, flow are restive, does not have sealing; Liquid or impurity get into bearing body, produce abrasion and corrosion to bearing, adopt rolling bearing; Stuck phenomenon can appear in easy-to-rust.
In addition; Chinese invention patent ZL200520091525.7 has proposed a kind of rotary screen type big-flow fire extinguishing sprayer; Utilization be arranged on the top base that is connected with water supply line and through with the top base bearing wheel axle bed that is rotatably assorted; Be located at swivel base below be fixed in the support go up, a taper current divider that the center faces base, be provided with the bar shaped sieve that outwards radially distributes mouthful through being located at current divider bottom one wheel face simultaneously, constitute rotary screen type big-flow fire extinguishing sprayer.Obviously each item is to have obtained expansion to this rotary screen type big-flow fire extinguishing sprayer on the coverage rate of water body spraying.But, because the setting of the rotating mechanism of this device and unreasonable, therefore in installing and using, have the immersion of churning water body and cause churning to be lost efficacy, thus the final fire extinguishing of influence effect.
Summary of the invention
The object of the invention just is to provide a kind of impelling centrifugal automatic rotary dispensing device; Both utilized the impact in the water source tube to form churning; Make it to have bigger water body impelling coverage rate, can ensure the water-proof function of rotating mechanism simultaneously again, reach the permanent reliability service of sprinkling fire function.
To achieve these goals; The technical scheme that the present invention adopts is such: the centrifugal automatic rotary dispensing device of impelling of the present invention; Comprise feed liquor standpipe body, upper end cover, bottom end cover and the taper flow-control tongue of being with flow channels, the flow-control tongue is arranged on the upper surface middle part of bottom end cover, and said feed liquor standpipe body is step-like tube connector; Socket one a no oily end face bearing and a no oily axial plane bearing successively on the feed liquor standpipe body; Said upper end cover is socketed in outside no oily axial plane bearing and the no oily end face bearing, and and no oily end face bearing between leave the gap, in the gap, be provided with seam axial plane seal; Seal is fixed in the gap through the locking nut that a sealed briquette and is connected with feed liquor standpipe body lower thread; Said bottom end cover is threaded with upper end cover, and the flow-control tongue is positioned at flow channels, is provided with spiral helicine parabola section opening around the flow-control tongue of bottom end cover.
As preferably, be provided with the seam sealing ring between said upper end cover and the bottom end cover.
As preferably, the sidewall of said bottom end cover is provided with side spray opening.
As preferably, said flow-control tongue is threaded with bottom end cover.
Compared with prior art, the invention has the advantages that:
1, this flusher is simple in structure in light weight; The bottom surface of bottom end cover is provided with parabola section opening; Liquid is under the effect of pressure and rotary centrifugal force; Spray out radially to diffuse the even impelling of mode from parabola opening and bottom end cover runner exit, be sprayed at uniformly in the solid space that radius is a 4.5-15 rice.
2, liquid forms raindrop under the collision effect of centrifugal force that rotates and flow-control tongue, and forms the nappe to the big raindrop of flusher lower space, and radius of protection is big, and the layout density of shower nozzle is little, and installation and fixing is set easily, has reduced construction costs.
3, adopt seam axial plane seal to prevent that liquid or impurity from getting into bearing body, produces abrasion and corrosion to bearing, the service life of extension fixture.
4, the nothing oil axial plane bearing that adopts, no oily end face bearing have reduced fretting wear, also not water funk dashing and the etch of other acid solution and washing away significantly, have overcome the bearing easy-to-rust of other rotary nozzles uses, stuck phenomenon occurs.
