Three, utility model content:
The utility model proposes a kind of multi-functional fine mist spray head at the prior art deficiency, has to concentrate and the diffusion spraying function, and simple in structure, pattern is changed fast, and is easy for operation, can in time switch jet mode fast according to field demand.
The technical scheme that the utility model adopted:
A kind of multi-functional fine mist spray head, comprise head body (1) and nozzle boss (2), described head body (1) and nozzle boss (2) are threaded, nozzle boss (2) afterbody is provided with the joint that connects hydraulic giant, be provided with concentrated atomized water spray outlet (3) in the center of head body (1) base portion, upward be distributed with a plurality of diffusion atomized water sprays outlets (4) in head body (1) to concentrate atomized water spray to export on the circumference that (3) are the center of circle, nozzle boss (2) middle part vertically is provided with extinguishing chemical or the flow inlet (5) that a cylindrical cavity is communicated with shower nozzle, the extinguishing chemical or the flow inlet both sides that are communicated with shower nozzle in the described cylindrical cavity are respectively equipped with the passage that is communicated with upward concentrated atomized water spray outlet of head body (1) and the outlet of diffusion atomized water spray, cylindrical cavity is interior by stopping that nut (6) is provided with a piston (7), the action bars of described piston (7) stretches out nozzle boss (2) outside, and the piston operation boom end is fixed with operating grip (8) by pin.Pull out operating grip (8), extinguishing chemical or flow inlet (5) form passage with diffusion atomized water spray outlet (4); Forward operation handle (8), extinguishing chemical or flow inlet (5) form passage with concentrated atomized water spray outlet (4).
Described multi-functional fine mist spray head, head body (1) outer face is the diffusing opening of falling the truncated cone shape, the diffusing opening of falling the truncated cone shape is provided with air intake opening (9) with the base portion joining place border that head body (1) is provided with jet exit.
Described multi-functional fine mist spray head, the extinguishing chemical on the upward concentrated atomized water spray outlet of head body (1) (3) and diffusion atomized water spray outlet (4) inside and the nozzle boss (2) or the internal diameter of current admission passage coupling part are greater than the internal diameter of concentrated atomized water spray outlet and the outlet of diffusion atomized water spray.
Described multi-functional fine mist spray head, the inside of upward concentrated atomized water spray outlet of head body (1) (3) and diffusion atomized water spray outlet (4) and the extinguishing chemical on the nozzle boss (2) or current admission passage coupling part inner chamber are provided with conveyor screw diversion column (10).
Useful good effect of the present utility model:
1, the multi-functional fine mist spray head of the utility model, change jet mode by a binary channels output with extinguishing chemical or flow inlet connection, adopt a piston to switch two passage duties, can long-range injection concentrate water smoke or spray diffusion water smoke, the jet mode replacing fast, in time, operation easily, easy to use, can improve fire fighter's Operational Effectiveness Rat, improve the fire extinguishing effect, practical. help holding opportunity of combat, exploit success rapidly.
2, the multi-functional fine mist spray head of the utility model, two kinds of jet modes all adopt direct current channel, and are simple in structure, processing easily, extinguishing chemical or the current pressure loss in nozzle is little, far firing range, jet performance, serviceability all improve largely.Because action component has only piston, piston and sealing ring thereof are changed easily, have therefore significantly improved shower nozzle service life.
Four, description of drawings:
Fig. 1: the multi-functional fine mist spray head structural representation of the utility model.
Five, the specific embodiment:
Embodiment one: referring to Fig. 1.The multi-functional fine mist spray head of the utility model, comprise head body 1 and nozzle boss 2, head body 1 is connected with the external screw thread coupling by internal thread with nozzle boss 2, the afterbody of nozzle boss 2 is provided with and connects Fire water syringe (other fire extinguisher, cleaning equipment or agricultural pesticide application apparatus) joint, be provided with concentrated atomized water spray outlet 3 in the base portion center of head body 1, the circumference that is the center of circle with concentrated water smoke outlet 3 on the head body 1 is provided with the diffusion atomized water spray outlet 4 of some, the middle part of nozzle boss 2 vertically is provided with extinguishing chemical or the flow inlet 5 that a cylindrical cavity is communicated with shower nozzle, the extinguishing chemical of connection shower nozzle or flow inlet both sides are respectively equipped with and are communicated with the passage of concentrating atomized water spray outlet 3 on the head body 1 and spreading atomized water spray outlet 4 in the cylindrical cavity, cylindrical cavity is interior by stopping that nut 6 is provided with a piston 7, the action bars of piston 7 stretches out nozzle boss 2 outsides, and the piston operation boom end is fixed with operating grip 8 by pin.When operating grip 8 was pulled out, extinguishing chemical or flow inlet 5 formed passage with diffusion atomized water spray outlet 4; Forward operation handle 8, extinguishing chemical or flow inlet 5 form passage with concentrated atomized water spray outlet 4.
