Abstract

The utility model belongs to the technical field of fire-fighting, which relates to a multi-nozzle adjustable water fog fire fighting spray head for fire extinguishing. The utility model is composed of a nozzle body (1), a spray head core (2), an adjustable bracket (3) and a spray head body (4), wherein, the right part of the spray head core (2) is provided with a symmetrical skewed slot A; the left end of the spray head core (2) is provided with a guide cone B; the spray head core (2) is connected with the adjustable bracket (3) through screw threads. Distance between the spray head core (2) and the nozzle body (1) can be adjusted by rotating the spray head core (2). Thereby, size of a rotational flow cavity of the spray head can be changed so that granularity of the water fog which is sprayed is changed, the utility model achieves the purpose of extinguishing fires with different kinds and sizes. The spray head can be provided with a plurality of nozzle holes according to requirements.

Description

Multiinjector is adjustable mist fire-fighting shower nozzle
The utility model belongs to the fire prevention field, relates to a kind of fire-fighting fire extinguishing adjustable mist fire-fighting shower nozzle of multiinjector.
As everyone knows; waterfog head is the crucial element of spraying system; it has under certain effect of water pressure; current are decomposed into tiny water smoke drop ejection rapidly; directly overlay the outer surface of the object of setting protection, impel the steam dilution and distribute the inhibition intensity of a fire; reduce fire and destroy, reduce explosion danger.At present, employed waterfog head adopts the principle of swirling flow atomizing more in the fire-fighting domain, its inner eddy flow core mostly is the baffle leaf structure, but the shower nozzle atomizing effect of this structure is limited, and the shower nozzle processing difficulties, the manufacturing cost height, be difficult to satisfy the needs of prior art development, therefore, the shower nozzle that needs a kind of novel fire-fighting fire extinguishing of design to use.
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, and a kind of simple in structure, the adjustable multiinjector of water smoke atomized particle size is adjustable mist fire-fighting shower nozzle is provided.
The purpose of this utility model is achieved in that the adjustable mist fire-fighting shower nozzle of multiinjector, by nozzle body (1), sprinkler core (2), adjustable support (3), sprayer body (4) is formed, the design of sprayer body (4) one ends has a through hole, link to each other with extraneous water source, sprinkler core (2) right-hand member has a symmetrical skewed slot A, there is a guiding awl B left part, nozzle bore (II) on the nozzle body (1) can be made a plurality of, sprinkler core (2) adopts with adjustable support (3) and is threaded, rotary nozzle core (2) can change distance between sprinkler core (2) and the nozzle body (1) to reach the size that changes eddy flow chamber (I), change the atomizing effect of water particle, to reach the purpose of go out different sizes and type fire.
The utility model compared with prior art has following advantage: 1, the nozzle bore (II) on the nozzle body (1) can be made one or more nozzles according to the size of fire extinguishing scope, the difference of type, forms multiinjector, to improve fire-fighting efficiency and fire-fighting area; 2, the distance between sprinkler core (2) and the nozzle body (1) can be controlled by adjustable support (3), adjusts distance and can reach the needed best water particle atomized particle size of the different fire that go out; 3, sprinkler core (2) right-hand member has the skewed slot A of two symmetries, when water passes through the skewed slot A of two symmetries, because the aerodynamic force effect forms the high speed rotary water current, forms thin water smoke from the nozzle bore ejection in eddy flow chamber (I).This structure is more simple in structure, easy to process than traditional baffle formula, and volume is little, and materials are few, and cost is low, and the water smoke atomizing effect that is produced is good.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the profile according to the adjustable waterfog head of multiinjector that the utility model proposes.
Fig. 2 is the schematic diagram according to the sprinkler core of the adjustable waterfog head of multiinjector that the utility model proposes.
The working condition of the concrete device that the utility model proposes below in conjunction with Fig. 1 and Fig. 2 explanation.
During shower nozzle work, add the liquid of a certain amount of additive in the clear water of fire extinguishing usefulness or the clear water, promote by the aerodynamic force pressurization, through hole directive sprinkler core (2) by sprayer body among Fig. 1 (4), thin water smoke by the ejection of the nozzle bore (II) on sprinkler core (2), eddy flow chamber (I), the nozzle body (1) spray pattern sprays to attack area and reaches fire-fighting fire extinguishing.Sprinkler core (2) right-hand member has two symmetrical skewed slots, and water under high pressure can produce high speed rotary motion through this, and sprinkler core (2) left end has a guiding awl, and the fluid of high speed rotation enters eddy flow chamber (I) through the guiding awl and sprays through nozzle bore (II).Sprinkler core (2) and adjustable support (3) be by thread connection, can adjust distance between sprinkler core (2) and the nozzle body (1) with the size in change eddy flow chamber (I) by rotary nozzle core (2).When eddy flow chamber (I) was big, the water smoke granularity of ejection was just big, and the distance of injection is just far away; As eddy flow chamber (I) hour, the water smoke granularity of ejection is with regard to little (atomizing effect is good), and the distance of injection is near, reaches the purpose dissimilar, big or small fire of going out in proper order.

Claims (3)

1, the adjustable mist fire-fighting shower nozzle of a kind of multiinjector, form by nozzle body (1), sprinkler core (2), adjustable support (3), sprayer body (4), it is characterized in that nozzle bore (I) is arranged on the nozzle body (1), inside is provided with eddy flow chamber (II), sprinkler core (4) right-hand member has two symmetrical skewed slots (A), and left end has a guiding awl (B).
2, the adjustable mist fire-fighting shower nozzle of multiinjector according to claim 1 is characterized in that sprinkler core (2) and adjustable support (3) pass through thread connection.
3, the adjustable mist fire-fighting shower nozzle of multiinjector according to claim 1, it is a plurality of to it is characterized in that nozzle bore (I) can be processed as required.
