Abstract
The utility model relates to a fire -fighting equipment field, concretely relates to adjustable foam gun admits air, its characterized in that: including bubble tube, pressure boost pipe and pipe box, be equipped with foaming chamber in the bubble tube, the one end of pressure boost pipe forms the pressure boost shower nozzle that the internal diameter reduces gradually, bubble tube is connected with the one end that the pressure boost pipe was equipped with the pressure boost shower nozzle, and the pressure boost shower nozzle lies in foaming chamber, intermural formation negative pressure passage in pressure boost shower nozzle outer wall and the foaming chamber, the last position that corresponds with negative pressure passage of bubble tube is equipped with a plurality of air inlets, the pipe box cover locate the bubble tube outer wall and bubble tube threaded connection, the pipe box can remove along the bubble tube axis to adjust the air inlet aperture. The utility model provides an adjustable fire -fighting foam rifle can be according to the foam liquid of different concentration and variance component, adjustment negative pressure passage size, and then adjustment air input to reach best foaming effect, thereby obtain better fire control effect.
Description
Technical field
This utility model is related to fire-fighting equipment field, is specifically related to a kind of adjustable foam gun of air inlet.
Background technology
Foam gun is portable fire-fighting equipment, and available tube tooth interface is connected with fire hose coupling, by fire-fighting pressure and bubble
Foam liquid mixes and sucks air, produces air foam.Air foam nozzle is main by gun barrel, handwheel, gun body, ball valve, pipette
Constitute with KY65 tube tooth interface, be used for putting out a fire to save life and property first, second, Class C liquid fire or injection water are used for general solid fire of putting out a fire to save life and property.Bubble
Foam rifle is general to be connected with foam hydrant using it is also possible to be used for foam fire truck.Inlet channel diameter in existing foam gun is fixing
, but for the foam solution of variable concentrations, the required air capacity of its foaming is different, existing foam gun cannot adjust into
Tolerance, so being unable to reach optimal foaming effect, and then affects extinguishing effect.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of adjustable foam gun of air inlet, can be according to variable concentrations
Foam solution, adjusts air inflow, to reach optimal foaming effect.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is as follows：Foam gun that a kind of air inlet is adjustable, its
It is characterised by：Including foamed pipe, pressure inlet and pipe box, in described foamed pipe, it is provided with foam chamber, one end of described pressure inlet is formed
Internal diameter diminishing supercharging shower nozzle, one end that described foamed pipe is provided with supercharging shower nozzle with pressure inlet is connected, and supercharging shower nozzle is located at
Foaming intracavity, forms negative pressure channel between supercharging shower nozzle outer wall and foaming cavity wall, corresponding with negative pressure channel in described foamed pipe
Position is provided with multiple air inlets, and described pipe box is sheathed on foam pipe outer wall and is threadeded with foamed pipe, and pipe box can be along foam
Pipe axis moves, to adjust air inlet aperture.
Further, described air inlet is provided with three, and is circumferentially uniformly arranged.
Further, described foaming intracavity is provided with foam screen.
Further, described pipe box outer wall is provided with anti-skidding lines.
Seen from the above description, the adjustable fire-fighting foam gun that this utility model provides can be according to variable concentrations and difference
The foam solution of composition, adjusts negative pressure channel size, and then adjusts air inflow, to reach optimal foaming effect, thus obtaining more preferably
Extinguishing effect.
Brief description
Fig. 1 is the structural representation of the adjustable foam gun of this utility model air inlet.
Fig. 2 is the sectional view of the adjustable foam gun of this utility model air inlet.
Specific embodiment
Below by way of specific embodiment, the utility model will be further described.
As depicted in figs. 1 and 2, the adjustable foam gun of air inlet described in the utility model, including foamed pipe 1, pressure inlet 2 and pipe
Set 3, is provided with foam chamber 11 in foamed pipe 1, one end of pressure inlet 2 forms internal diameter diminishing supercharging shower nozzle 21, foamed pipe 1 with
One end that pressure inlet 2 is provided with supercharging shower nozzle 21 connects, and supercharging shower nozzle 21 is located in foam chamber 11, is pressurized shower nozzle 21 outer wall and foaming
Form negative pressure channel 111, in foamed pipe 1, position corresponding with negative pressure channel 111 is provided with multiple connection negative pressure and leads between the inwall of chamber 11
The air inlet 12 in road 111, in the present embodiment, air inlet 12 is provided with three, and is circumferentially uniformly arranged, in other embodiments,
Air inlet 12 can be two, or is arbitrarily more than three integer, pipe box 3 be sheathed on foamed pipe 1 outer wall and with foamed pipe 1 screw thread
Connect, foamed pipe 1 outer wall is provided with external screw thread, pipe box 3 inwall is provided with the female thread with external screw thread cooperation, pipe box 3 can cover air inlet
Mouth 12, pipe box 3 can move along foamed pipe 1 axis, and to adjust air inlet 12 aperture, air inlet 12 can open completely, portion is separate
Put or completely obscured, in foam chamber 11, be provided with foam screen 13, pipe box 3 outer wall is provided with anti-skidding lines.
As depicted in figs. 1 and 2, foam solution enters in pressure inlet 2 and is injected in foam chamber 11 from supercharging shower nozzle 21, high
The foam solution of pressure forms negative pressure, and outside air is inhaled into foam chamber 11, air and bubble via air inlet 12 and negative pressure channel 111
Foam liquid mixed foaming, foam screen 13 can make foaming evenly abundant.
Above are only some specific embodiments of the present utility model, but design concept of the present utility model is not limited to
This, all changes that using this design, this utility model is carried out with unsubstantiality, infringement this utility model protection domain all should be belonged to
Behavior.
