Description
Technical field
The utility model relates to nozzle field, particularly relates to a kind of fire nozzle.
Background technology
Closely, one is that to be commonly called as one be more professional saying to the meaning of nozzle and shower nozzle.Shower nozzle is a variety of sprays, spraying, oil spout, parts very crucial in abrasive blast equipment, or even critical piece.Fire nozzle is also a kind of shower nozzle, fire-fighting spraying head is used for spraying system of fire fighting, when a fire, water is spilt by spray head splash box puts out a fire, and is divided into sagging type sprinkler tip, upright sprinkler, conventional sprinkler, sidewall sprinkler head etc. at present.During breaking out of fire, fire water is evenly spilt by spray head, plays control to the intensity of a fire of certain area, and common shower header type has: sagging type, erect type, plain edition and abutment wall type.The nozzle place of the spray head under prior art is unlimited, and nozzle exposes in atmosphere for a long time, causes easily accumulating dust in nozzle, the impurity such as oil smoke, thus causes spray nozzle clogging.When there is the condition of a fire, nozzle may lose efficacy and cannot use, and caused economic loss or personal injury.
Utility model content
The utility model, in order to overcome deficiency of the prior art, provides a kind of fire nozzle, and the cone mouth place of this fire nozzle is provided with cone seals cone mouth, prevents the plug nozzle such as dust, oil smoke, ensures that nozzle normally works under the condition of a fire, safeguards personal safety as well as the property safety.
The utility model is achieved through the following technical solutions:
A kind of fire nozzle, comprise body, cone, described cone is connected with connecting rod, the other end of described connecting rod and screw assembly, described body is provided with flow channel for liquids, it is characterized in that: described flow channel for liquids is circumferentially uniform at one along the axis of body, is provided with spring between described screw and body; Described body is provided with external screw thread.
Fire nozzle is connected on pipeline by the external screw thread on body, and under the effect of spring force, spring jacking screw, makes the outer surface of cone and cone mouth be close to, seal fluid runner, prevent dust, oil smoke enters in flow channel for liquids from cone mouth.In the generation condition of a fire, in opening conduits during valve, fluid pressure jack-up cone, when the pressure of liquid effects in cone and spring force balance, have gap between cone and cone mouth, liquid sprays away from gap.
As optimal technical scheme of the present utility model, described screw is provided with notch, conveniently tightens or unload screw.
As optimal technical scheme of the present utility model, the outer surface of described cone and the inner surface of cone mouth are fitted.
Compared with prior art, the beneficial effects of the utility model are: the utility model utilizes cone seals cone mouth, under the non-condition of a fire, prevent dust, oil smoke etc. from entering in flow channel for liquids, avoiding fire nozzle blocked, ensureing that fire nozzle normally works when there is the condition of a fire.The utility model has simple, the practical feature reliably of structure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that A-A of the present utility model is to sectional view.
In figure: 1, screw; 2, notch; 3, spring; 4, external screw thread; 5, body; 6, flow channel for liquids; 7, cone mouth; 8, connecting rod; 9, cone.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 2, Fig. 1 is structural representation of the present utility model, and Fig. 2 is that A-A of the present utility model is to sectional view.
Described a kind of fire nozzle, comprise body 5, cone 9, described cone 9 is connected with connecting rod 8, the other end of described connecting rod 8 and screw 1 assembly, described body 5 is provided with flow channel for liquids 6, described flow channel for liquids 6 is circumferentially uniform at one along the axis of body 5, is provided with spring 3 between described screw 1 and body 5; Described body 5 is provided with external screw thread 4.
Fire nozzle is connected on pipeline by the external screw thread 4 on body 5, and under the effect of spring 3 elastic force, spring 3 jacking screw 1, makes the outer surface of cone 9 and cone mouth 7 be close to, seal fluid runner 6, prevent dust, oil smoke from entering in flow channel for liquids 6 from cone mouth 7.In the generation condition of a fire, in opening conduits during valve, fluid pressure jack-up cone 9, when the pressure of liquid effects in cone 9 and spring 3 Spring balanced, have gap between cone 9 and cone mouth 7, liquid sprays away from gap.
As a preferred embodiment of the present utility model, described screw 1 is provided with notch 2, conveniently tightens or unload screw 1.
As a preferred embodiment of the present utility model, the outer surface of described cone 9 and the inner surface of cone mouth 7 are fitted.
Compared with prior art, the utility model utilizes cone 9 to seal cone mouth 7, under the non-condition of a fire, prevents dust, oil smoke etc. from entering in flow channel for liquids 6, avoids fire nozzle blocked, ensures that fire nozzle normally works when there is the condition of a fire.The utility model has simple, the practical feature reliably of structure.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
