Abstract
The utility model relates to a fire-fighting hydraulic giant provided with rifling, belonging to the filed of a fire-fighting tool. The fire-fighting hydraulic giant adopts the technical scheme that the rifling is marked on the inner wall surface of a water outlet of the fire-fighting hydraulic giant, and the rifling can be left-hand rotated and right-hand rotated. The rifling can be flute rifling, also can be groove rifling. The fire-fighting hydraulic giant has the benefits that spiral concave-convex lines are arranged in a bore at a nozzle part of the fire-fighting hydraulic giant, the groove rifling and the flute rifling can lead the water flow at the water outlet to be concentrated and not to splash, and the fire-extinguishing radius can be increased under the equal water pressure. When the water pressure is smaller, the groove rifling and the flute rifling can still lead the water flow to be concentrated at the nozzle part of the fire-fighting hydraulic giant, and the fire-extinguishing radius can be increased under the same water pressure. The fire-fighting hydraulic giant can be used for fire-fighting sprinkling, and solves the technical problem of remote concentrated sprinkling in fire-fighting.
Description
Technical field
The utility model relates to a kind of fire-fighting lance, a kind of specifically fire-fighting lance that has rifling., belong to the fire-fighting field of tool.
Background technology
Fire-fighting lance is one of fireman's requisite main tool of being used to put out a fire, after linking with fire hydrant, need under high pressure the water column that forms be sprayed to ignition point, and big fire is put out by water the most at last.The problem of the fire-fighting lance existence of using now is to need current to produce higher pressure, and the fire extinguishing radius could increase, and also could produce the column current, sprays to ignition point at a distance; If when hydraulic pressure is low, then can't form the column current, make the fire extinguishing radius reduce, be unfavorable for fire extinguishing, even can't finish the fire extinguishing task sometimes at all.
The utility model is exactly in order to solve this subject matter, with the rifling technology transplant to fire-fighting lance, thereby realized new result of use.Rifling also claims rifling, concavo-convex twist line in rifle, the bore.Recessed part is called groove, and the part of projection is called land.The effect of rifling is to make bullet produce fast rotational, that is to say to make bullet awing around the axis rapid circular movement of oneself, to keep flight stability, improves accuracy at target.
Summary of the invention
Goal of the invention of the present utility model just provides and a kind ofly in fire-fighting lance delivery port section rifling is set, thereby reaches concentrated water outlet, increases the fire-fighting lance of current range.
Using current has the effect of acceleration, reaches concentrated water outlet, and increasing range is second purpose of the present utility model.
Realize that the technical solution of the utility model is such: fire-fighting lance is by water inlet, and delivery port 1 constitutes, and is carved with rifling 2 on the internal face of delivery port 1.That this rifling 2 can be is left-handed, also can be dextrorotation.Rifling 2 can be land, also can be groove.
In the thorax of fire-fighting lance spout position concavo-convex twist line is arranged, the existence of groove and land can make the delivery port current concentrate and do not produce and splash, and can increase the fire extinguishing radius simultaneously under equal hydraulic pressure.When hydraulic pressure hour, the existence of groove and land still can make fire-fighting lance spout position current concentrate, and can increase the fire extinguishing radius under the hydraulic pressure on an equal basis simultaneously.
The beneficial effects of the utility model are: in the thorax of fire-fighting lance spout position concavo-convex twist line is arranged, the existence of groove and land can make the delivery port current concentrate and do not produce and splash, and can increase the fire extinguishing radius simultaneously under equal hydraulic pressure.When hydraulic pressure hour, the existence of groove and land still can make fire-fighting lance spout position current concentrate, embodying under equal hydraulic pressure simultaneously increases the radius of putting out a fire.
Description of drawings
Below in conjunction with accompanying drawing of the present utility model, further describe its specific embodiment.
Fig. 1 is an agent structure schematic diagram of the present utility model.
Among the figure: 1 is delivery port, and 2 is rifling.
The specific embodiment
Embodiment: fire-fighting lance is by water inlet, and delivery port 1 constitutes, and is carved with rifling 2 on the internal face of delivery port 1.
That this rifling 2 can be is left-handed, also can be dextrorotation.Rifling 2 can be land, also can be groove.
Above-mentioned fire-fighting lance with rifling has following advantage:
1. in the thorax of fire-fighting lance spout position twist concavo-convex line is arranged, the existence of groove and land can make The delivery port current are concentrated and are not produced and splash, and can increase the fire extinguishing radius simultaneously under equal hydraulic pressure.
When hydraulic pressure hour, the existence of groove and land still can make fire-fighting lance spout position water adfluxion In, under equal hydraulic pressure, can increase the fire extinguishing radius simultaneously.
Claims (3)
1, the fire-fighting lance that has rifling, forming has water inlet, and delivery port (1) is characterized in that: be carved with rifling (2) on the internal face of delivery port (1).
2, the fire-fighting lance that has rifling according to claim 1 is characterized in that: rifling (2) can be left-handed, also can be dextrorotation.
