Abstract
The utility model discloses a moveable high-pressure single-fluid water mist dual-purpose spray head, which mainly comprises a nozzle carrier 7, a bunch seal pad 9, a rotating connector 12 and a body 10. The peripheral surface of the body 10 is homogeneously provided with water jets 13, the nozzle carrier 7 is provided with 9 nozzles, each nozzle comprises a nozzle body 1, a nozzle plate 2, a splitter 3, a screw core 4 and a filtering core 5, and the nozzle body 1 is arranged on the nozzle carrier 7. After the spray head assembling, the screw on the rotating connector 12 is connected with the airbrush. The utility model has the advantages of, 1, good atomizing effect, the inner structure of the nozzle can create droplet whose diameter is smaller than 100 mu m. 2, large flow capacity, when the pressure of water inlet opening is 10 MPa, the flow capacity can reach 7L/ min. 3, fast changing between atomizing and sprinkling.
Description
Technical field
The utility model relates to portable fire-fighting equipment, and especially a kind of only is the dual-purpose shower nozzle of the thin water smoke of high pressure single fluid of medium with the pure water.
Background technology
At present fine water mist fire-extinguishing system is divided into the thin water smoke of pure water single fluid go out water system and gas-liquid two-fluid fine water mist fire-extinguishing system.The former is divided into three kinds of high pressure, middle pressure and low pressure again.So-called high pressure single fluid fine water mist fire-extinguishing system, (pressure is greater than 3.5Mpa to make water under high pressure exactly, be generally 8-14Mpa) by force by the heavy pressure fine spray shower nozzle, under special shower nozzle effect, to flow through the water atomization of shower nozzle, make drop diameter less than 100-400 μ m, visible fine mist spray head is the crucial element of high pressure single fluid fine water mist fire-extinguishing system.It has makes water smoke change into rapidly under certain hydraulic pressure effect to have certain mist flux; the spray of mist momentum and atomizing cone angle sprays to protected district; in the process of droplet gasification; 1700 times of its volumetric expansions; the temperature in protected district is cooled off rapidly; oxygen barrier and blocking radiant heat, thus reach desirable fire extinguishing effect.Because high pressure single fluid fine water mist fire-extinguishing system has plurality of advantages such as water-saving and environmental protection, is just obtaining to use widely.
The utility model content
The purpose of this utility model provide a kind of simple in structure, be the dual-purpose shower nozzle that medium possesses the high pressure single fluid water mist system of the atomizing and the two kinds of functions of spraying water with the pure water.
The technical solution of the utility model is: the dual-purpose shower nozzle of a kind of thin water smoke of portable high pressure single fluid, and it mainly is made up of nozzle carrier, combination sealing pad, adapter and body; Uniform water jet on the side face of body, uniform nozzle on the side face of nozzle carrier; Each nozzle is made up of nozzle body and dress nozzle plate and deflector within it; Nozzle body is screwed on the nozzle carrier with screw thread; After the shower nozzle combination, be connected with spray gun with the screw thread on its adapter.
Filter core is housed in nozzle body.
Nine nozzles are installed on the nozzle carrier.
The utility model has following advantage:
1, nozzle atomization is effective.When the pressure of shower nozzle water inlet was 12Mpa, the nozzle interior structure made the fogdrop diameter of generation less than 100 μ m.
2, flow is big.When the pressure of shower nozzle water inlet was 10Mpa, capacity of sprinkler can reach 7l/min.
3, conversion is fast between spraying and the spray.
4, the utility model is not only applicable to fire-fighting fire extinguishing, is applicable to other field that needs spraying or spray yet.
Description of drawings
Fig. 1 is a structural front view of the present utility model,
Fig. 2 is a structure right view of the present utility model,
The specific embodiment
The structure of the dual-purpose shower nozzle of the portable thin water smoke of high pressure single fluid is made up of nozzle body 1, nozzle plate 2, deflector 3, spiral shell core 4, filter core 5, O shape circle 6, nozzle carrier 7, O shape circle 8, combination sealing pad 9, body 10, O shape circle 11, adapter 12 etc. as shown in Figure 1 and Figure 2.After the shower nozzle combination, be connected with spray gun with the screw thread on its adapter.
In the time of need being used for high pressure single fluid fine mist fire-fighting, tighten nozzle carrier 7 clockwise, the screw thread end face on the nozzle carrier compresses combination sealing pad 9.Open Switch of spray pistol, water under high pressure is through the cavity of adapter 12 flow nozzle seats 7, makes High-Pressure Water form high-intensity turbulent flow and rotation through filter core 5, spiral shell core 4 and deflector 3 again, at last the aperture ejection from the nozzle plate.Produce spray in the exit of nozzle body 1 and spray to the protection zone, reach the purpose of rapid fire extinguishing with certain atomizing cone angle and mist flux.In the time of need being used to spray, rotate counterclockwise nozzle carrier 7, the groove on the nozzle carrier 7 is alignd with groove on the body 10.High-Pressure Water flows into body plenum from the circular passage that forms between nozzle carrier 7 and the adapter 12, and 24 water jets 13 from the body 10 penetrate then.
Each nozzle has a filter core 5, guarantees that High-Pressure Water diameter from nozzle plate is with the form ejection of atomizing 0.5 millimeter the aperture.In case filter core 5 is blocked, the available spare part that provides is changed rapidly.
Dual-purpose shower nozzle both can be used for high pressure single fluid fine water mist fire-extinguishing system, also can be used for needing at ordinary times to be used to have the place of certain intensity spray, had obvious social and economic benefit.
