The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in detail.
Fig. 1 is the structural representation of multi-functional water smoke fire extinguishing spray gun, and rifle body 4, smooth-bore tip body 5, the shower nozzle 12 that has a plurality of nozzles 18 connect successively, are disposed with turbulent chamber 6, hybrid chamber 8, the smooth-bore tip passage 9 of connection in the smooth-bore tip body 5.The fluid passage 19 that be provided with fluid pipeline 2 in the rifle body 4, is communicated with turbulent chamber is provided with switch valve 3 between fluid passage and the fluid pipeline, switch valve 3 contacts with rifle switch 21, and the action of rifle switch can open or close fluid passage.Fluid pipeline is connected with liquid source 17 by fast interface.On the external wall of smooth-bore tip, be provided with the auxiliary flow passway 15 that is communicated with turbulent chamber 6 with 6 corresponding positions, turbulent chamber, be provided with the air intlet 14 that is communicated with hybrid chamber 8 with hybrid chamber 8 corresponding positions, auxiliary flow passway and air intlet are provided with sliding sleeve 7, slide on the external wall of smooth-bore tip and slide, be used to open or close auxiliary flow passway 15 and air intlet 14.In order to realize the conversion of droplet and direct current bubble condition, shower nozzle 12 is connected with smooth-bore tip body 5 usefulness gusset pieces 10 hinges, realize the upset of shower nozzle.Support 11 is fixedlyed connected with gusset piece 10, and described shower nozzle is connected by screw thread 13 with support.When shower nozzle and smooth-bore tip body forward a straight line to, utilize the shower nozzle screw thread to be connected with support screw thread 13, shower nozzle and support are tightened to one, penetrate by the nozzle in the shower nozzle by smooth-bore tip passage 9 press waters, form droplet water smoke.When needs direct current spray foam, rotary nozzle makes itself and smooth-bore tip body disengage downward upset, realizes the direct current spray foam.Above-mentioned is the single-phase flow operating mode, and wherein, switch valve 3 is the 2/2-way valve.
In order to realize the two-phase flow function, the both sides of switch valve 3 are respectively arranged with gas passage 20 and gas pipeline 1 in rifle body 4, described gas pipeline 1 is connected with source of the gas by fast interface, be provided with check valve 16 in the fast interface of gas pipeline, at this moment, switch valve 3 is two position four-way valves, with connection or closing liquid and gas passage.The outlet of gas passage is positioned at the center in turbulent chamber.
Nozzle in this spray gun can adopt hydraulic spray nozzle commonly used, in order to improve fogging degree, can adopt nozzle as shown in Figures 2 and 3, comprise the nozzle body 28, conical nozzle core 23 and the jet expansion 27 that have conical cavity, wherein the front end of nozzle core 23 is the bulb shape, on the inwall of nozzle body 28 or the nozzle core outer wall be provided with helical groove, form nozzle chambers 26 between the bulb of conical cavity and nozzle core 23, nozzle chambers 26 is connected with jet expansion 27, and the center of conical nozzle core 23 is provided with the passage 24 that is communicated with nozzle chambers.Since on the inwall of nozzle body 28 or the nozzle core outer wall be provided with helical groove, make and form helical duct 25 between the inwall of the outer wall of nozzle core 23 and nozzle body 28, like this, just make the fluid that flows into by the conical cavity upper end quicken rotation along helicla flute and bulb, the jet stream of centre bore is to nozzle chambers, and different flowing sprays conical droplet water smoke by jet expansion in nozzle chambers.The particle of the water droplets of wherein being careless or thoughtless by nature is big and far firing range prolongs range thereby drive droplet.
In order to reduce the resistance of current, liquid is sprayed from a plurality of spray orifices.At this moment, be provided with a cavity that is communicated with turbulent chamber at turbulent chamber front end, the outlet of fluid passage is communicated with cavity, and cavity is communicated with by a plurality of spray orifices with turbulent chamber.In turbulent chamber, compressed air is penetrated by centre bore, forms gas jet, and its surrounding liquid is sprayed by one or more spray orifices, converges to venturi 22 places, is penetrated by flow control hole together.
During use, be communicated with compressed air and pressure extinguishing fluid source respectively by rifle switch control gas passage and fluid passage, be the two-phase flow operating mode, sliding sleeve 7 is moved to the place ahead occluded air import 14, open auxiliary flow passway 15 augmented flows, forward shower nozzle 12 and smooth-bore tip body 5 to a straight line, utilize the shower nozzle screw thread to be connected with support screw thread 13, shower nozzle and support are tightened to one, can spray trickle water smoke.Rotary nozzle and smooth-bore tip body break away from, and upset downwards, can the direct current spray foam.Pull down the gas pipeline fast interface, closed check valve only connects pressure extinguishing fluid source and is the single-phase flow operating mode.With sliding sleeve 7 reach occluded air imports 14, open auxiliary flow passway 15, forward shower nozzle 12 and smooth-bore tip body 5 to a straight line, and connect with support, can realize droplet ejection.If with the mobile backward air intlet 14 of opening of sliding sleeve 7, conversion nozzle 12 breaks away from the smooth-bore tip body downwards, can the direct current spray foam.
Although relate to a kind of multi-functional water smoke fire extinguishing spray gun and carried out special description disclosed with reference to embodiment, embodiment described above is illustrative and not restrictive, under the situation that does not break away from spirit and scope of the present utility model, all variations and modification are all within scope of the present utility model.
