Abstract

The utility model discloses a novel compound extinguishing spry gun structure, mainly comprising a liquid channel (1), a dry powder channel (2) and a compound cavity (3) provided with an outlet (5). The liquid channel (1) and the dry powder channel (2) are communicated with the compound cavity (3) and are provided with a control switch (4). The utility model can mix and spray the dry powder and the extinguishing liquid, which improves the spraying distance greatly, expands the extinguishing range, improves the extinguishing efficiency and reduces the explosion and burning possibility.

Description

A kind of novel mixed fire extinguishing ejecting gun structure

Technical field

The utility model relates to a kind of novel mixed fire extinguishing ejecting gun structure.

Background technology

Existing fire-fighting technique generally adopts extinguishing chemical fire extinguishings such as water, foam solution, dry powder, by single tube road conveying extinguishing agent to spray gun or big gun, the extinguishing chemical that ejects becomes the nature physical state, that is: water becomes water column or spray water, foam solution becomes natural shaped regular-type foam by contacting with atmosphere, and dry powder is directly injected to the scene of fire.Development along with fire prevention, we find two or more extinguishing chemicals are ejected the formation compound fire-extinguishing agent simultaneously, have higher fire-fighting efficiency, particularly at petrochemical industry fire, electrical fire etc., compound fire-fighting technique demonstrates its fire extinguishing advantage more.And how multiple extinguishing chemical is ejected into the scene of fire simultaneously, just become a technical barrier.The particularly injection of powder extinguishing agent, because dry powder is solid, light specific gravity, particle is thin, thereby jet length is near, can not satisfy the requirement of jet length in a lot of scenes of fire, and this is restricted with regard to the application that makes dry-chemical fire extinguishing.

The utility model content

The purpose of this utility model is in order to overcome the deficiencies in the prior art and defective, a kind of novel mixed fire extinguishing ejecting gun structure is provided, this fire extinguishing ejecting gun structure can make dry powder and extinguishing fluid spray after mixing, improved jet length greatly, increased the fire extinguishing scope, improve fire-fighting efficiency, reduced the possibility of detonation.

The purpose of this utility model is achieved through the following technical solutions: a kind of novel mixed fire extinguishing ejecting gun structure, mainly constitute by fluid passage, dry powder passage and the hybrid chamber that has an outlet, described fluid passage and dry powder passage all are connected with hybrid chamber, and fluid passage and dry powder passage all are equipped with gauge tap.

Aforesaid liquid passage and dry powder passage all are equipped with gauge tap, control the injection of extinguishing fluid and dry powder respectively.

The aforesaid liquid feeder connection links to each other with the extinguishing fluid supply source, is used for the conveying of the mixture of water, foam solution and water and foam solution.Fluid passage stretches to the middle part of hybrid chamber by the inlet of hybrid chamber, can guarantee fully that the extinguishing fluid runner is unobstructed, forms wall attachment effect around the liquid simultaneously.

Above-mentioned dry powder feeder connection is connected with the dry powder supply source, is used for the conveying of dry powder.Described dry powder passage and hybrid chamber junction are positioned on the adjacent sidewall of inlet, and are structure as a whole, and after dry powder enters hybrid chamber, utilize the effect of fluid passage outer wall that the dry powder runner is become annular.

Dry powder and liquid mix and energy exchange at hybrid chamber, because the kinetic energy of water and the attached wall effect of water, dry powder reaches consistent with liquid in the speed of hybrid chamber outlet, thereby dry powder can be ejected into and water distance much at one, water has certain cooling and fire extinguishing effect, and dry powder has powerful fire extinguishing effect, forms compound fire-extinguishing agent efficiently.

Described outlet is positioned on the sidewall of hybrid chamber, has inlet on the relative sidewall of outlet.

Described fluid passage stretches to the middle part of hybrid chamber by the inlet of hybrid chamber.

The arrival end sidewall of the outer wall of described fluid passage and hybrid chamber forms hermetically-sealed construction.

Described dry powder passage and hybrid chamber junction are positioned on the adjacent sidewall of inlet, and are structure as a whole.

Described gauge tap is a valve.

In sum, the utility model compared with prior art has following advantage:

(1) the utility model can make dry powder and extinguishing fluid spray after mixing in hybrid chamber, has improved jet length greatly, and the fire extinguishing scope is expanded greatly.

(2) the utility model can make dry powder and extinguishing fluid form a kind of compound fire extinguishing effect, and its fire extinguishing benefit improves greatly.

The ability of the mixed liquor control fire that forms after (3) dry powder and extinguishing fluid mix is strong, and blow-off velocity is fast, has reduced the formation of smog, has lowered the possibility of detonation.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Mark and corresponding parts title in the accompanying drawing: 1-fluid passage; 2-dry powder passage; The 3-hybrid chamber; The 4-gauge tap; The 5-outlet; The 6-inlet.

The specific embodiment

Below in conjunction with embodiment and accompanying drawing, to the detailed description further of the utility model do, but embodiment of the present utility model is not limited thereto.

Embodiment:

A kind of novel mixed fire extinguishing ejecting gun structure as shown in Figure 1 as can be known, this fire extinguishing ejecting gun structure is mainly by fluid passage 1, dry powder passage 2 and have outlet 5 hybrid chamber 3 and constitute, described fluid passage 1 and dry powder passage 2 all are connected with hybrid chamber 3, and fluid passage 1 and dry powder passage 2 all are equipped with gauge tap 4.

Described outlet 5 is positioned on the sidewall of hybrid chamber 3, has inlet 6 on outlet 5 relative sidewalls; Fluid passage 1 stretches to the middle part of hybrid chamber 3 by the inlet 6 of hybrid chamber 3; The arrival end sidewall of the outer wall of fluid passage 1 and hybrid chamber 3 forms hermetically-sealed construction; Dry powder passage 2 and hybrid chamber 3 junctions are positioned on the adjacent sidewall of inlet 6, and are structure as a whole; Gauge tap 4 is a valve.

When needs are used extinguishing device, all gauge taps to be opened, dry powder enters hybrid chamber 3 by dry powder passage 2, after entering hybrid chamber 3, utilizes fluid passage 1 outer wall that dry powder runner 2 is become annular; Extinguishing fluid enters hybrid chamber 3 middle parts by fluid passage 1, form orderly the mixing with dry powder, dry powder and liquid energy exchange, because the kinetic energy of water and the attached wall effect of water, dry powder reaches consistent with liquid in the speed of hybrid chamber 3 outlets, thereby dry powder can be ejected into and water distance much at one, because water has certain cooling and fire extinguishing effect, and dry powder has powerful fire extinguishing effect, thereby forms compound fire-extinguishing agent efficiently, reaches good fire extinguishing effect.

From the above, the utility model can make dry powder and extinguishing fluid spray after mixing, and has improved jet length greatly, has increased the fire extinguishing scope, has improved fire-fighting efficiency, has reduced the possibility of detonation.

As mentioned above, just can realize the utility model preferably.
