Abstract
The utility model relates to a low pressure atomizing fire-fighting squirt gun, comprising a gun body, the interface of a fire-fighting pipe, a water inlet pipe and a nozzle. The low pressure atomizing fire-fighting squirt gun is characterized in that a valve cavity is arranged in the gun body. The back end of the valve cavity is connected with the water inlet pipe, the front end of the valve cavity is connected with an inner cylinder, and a valve ball is arranged in the valve cavity. The valve ball is connected with a spanner on the gun body. The front end of the inner cylinder is provided with the nozzle. A swirling flow piece is arranged between the inner cylinder and the nozzle. The swirling flow piece is a circular piece which is embedded in a groove arranged at the connecting position of the inner cylinder and the nozzle. Swirling flow holes are all arranged on the center of the swirling flow piece and the circumference which is concentric with the swirling flow piece. Inclined holes make the swirling flow holes on the circumference which is concentric with the swirling flow piece as a tangential direction. The nozzle comprises three sections; the connecting position of the inner cylinder and the nozzle is a conical pipe; the intermediate section is a straight cylinder section; a water outlet is a conical hole whose opening increases gradually. The advantage of the utility model is that the low pressure atomizing fire-fighting squirt gun can be used for extinguishing fire hazards caused by the combustion of solid, liquid and gas; the fire-extinguishing effect is conspicuous; and the water inlet pipe and the squirt gun are in an oblique angle, which is convenient to hold and control and can decrease reactive force.
Description
Technical field
The utility model relates to a kind of fire-fighting lance, particularly a kind of low pressure spraying fire-fighting lance.
Background technology
The at present domestic fire-fighting lance fire extinguishing of generally adopting because extinguishing chemical is a water, is mainly used in and puts out the fire that combustion of solid objects takes place.And when being used to put out liquid fire and gas fire, the fire extinguishing effect of its direct projection spraying current is very poor, fuel oil may be dashed even and penetrate the back flow burning.With above-mentioned fire-fighting lance in when fire extinguishing because the utilization rate of water is lower, and after fire extinguishing, completely be water, water damage is big.The existing fiery water fog nozzle of oil that can go out generally is to adopt water under high pressure, the restriction of the pipe pipe range that in use is under pressure, and pipeline is oversize, and then hydraulic pressure reduces, and can't spray, and put out a fire in the short scene of a fire that then can't enter of pipeline.
Summary of the invention
Traditional low pressure fire-fighting lance is mainly used in and puts out the fire that combustion of solid objects takes place in the purpose of this utility model solution prior art, and can't put out the problem of liquid fire and gas fire, a kind of spraying fire-fighting lance that can produce the low pressure spray effect is provided.The utility model design low pressure spraying fire-fighting lance, comprise rifle body, extinguishing pipe interface, water inlet pipe, nozzle, it is characterized in that: in the rifle body, valve pocket is arranged, the rear end of valve pocket connects water inlet pipe, the front end of valve pocket is connected with inner core, and valve ball is arranged in the valve pocket, and valve ball is linked to each other by the spanner on the rifle body, the inner core front end has nozzle, between inner core and nozzle spinning disk is arranged.Spinning disk is a circular piece, and circular piece embeds in the groove of inner core and nozzle junction, the circle centre position of spinning disk reach with the concentric circumference of spinning disk on divide equally whirl hole arranged.Along with the concentric circumference of spinning disk on whirl hole be tangential inclined hole.Nozzle has three sections formations, with the inner core junction be a Taper Pipe, the stage casing is a direct tube section, delivery port is the cumulative conical bore of an opening.The utility model has the advantages that the fire that can be used for putting out solid, liquids and gases burning generation, the fire extinguishing effect is remarkable, the utilization rate height of water, and water inlet pipe and hydraulic giant are the oblique angle, are convenient to hold control and can reduce reaction force.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated,
Accompanying drawing 1 is a structural representation of the present utility model,
Accompanying drawing 2 is a spinning disk structural representation of the present utility model,
The specific embodiment
Comprise rifle body 1, extinguishing pipe interface 2, water inlet pipe 3, nozzle 4 among the figure, it is characterized in that: valve pocket 5 is arranged in rifle body 1, the rear end of valve pocket 5 connects water inlet pipe 3, the front end of valve pocket 5 is connected with inner core 6, valve ball 7 is arranged in the valve pocket 5, valve ball 7 is linked to each other by the spanner on the rifle body 18, and inner core 6 front ends have nozzle 4, and 4 at inner core 6 and nozzle have spinning disk 9.Spinning disk 9 is a circular piece, and circular piece embeds in the groove 10 of inner core 6 and nozzle 4 junctions, the circle centre position of spinning disk 9 and with the concentric circumference of spinning disk 9 on divide equally whirl hole 11 arranged.Along with the concentric circumference of spinning disk 9 on whirl hole 11 be tangential inclined hole.Nozzle 4 has three sections formations, with inner core 6 junctions be a Taper Pipe, the stage casing is a direct tube section, delivery port is the cumulative conical bore of an opening.
On hydraulic giant, spanner 8 is pushed away forward, valve ball 7 is turn-offed, and the sealing ring driving fit on sphere 7 and the valve pocket 5, hydraulic giant is in closed condition, enter hydraulic giant rifle body 1 when pressure water source passes through fire hose and extinguishing pipe interface 2 and water inlet pipe 3, at this moment hydraulic giant is in dormant state.
When using " spraying " current, shift the spanner on the hydraulic giant 8 onto open position, press water can be crossed spinning disk 9 by inner core 6, press water is after process inner core 6 and spinning disk 9, current are because the tangential shunting and the rotation of circumferential whirl hole 11 on spinning disk 9, collision is simultaneously pushed mutually again and is entered in the nozzle 4, when such current reach nozzle 4 outsides through nozzle 4, originally lived in concentrated communities the portion of energy in 4 li current of nozzle, obtain rapidly discharging, thereby current are split into countless tiny particle waters, and the energy that a part of straight line of spinning disk 9 central whirl hole 11 sprays sprays the vaporific current of i.e. formation injection forward with countless tiny particle waters.
