Specific implementation mode
In the following, in conjunction with attached drawing and specific implementation mode, the utility model is described further, it should be noted that
Under the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new
Embodiment.
The concept of every directionality for being related to upper, lower, left, right, front and rear or directionality is in the following description
For the location of the figure being described state, it is therefore intended that facilitate public understanding, thus cannot be understood
To be particularly limited to technical solution provided by the utility model.
It is a kind of structural schematic diagram of fire monitor head provided by the utility model, the big gun head (not shown) packet shown in Fig. 1-3
Include long tube 3, transitional connection pipe 5 and long bobbin 9, firing-fighting medium from long tube 3 followed by transitional connection pipe 5 and long bobbin 9, finally
It is sprayed from the nozzle 92 of 9 upper end of long bobbin；It is equipped with conical guiding sleeve 6 in the transitional connection pipe 5, firing-fighting medium is from conical guiding sleeve
6 heavy caliber end flows into, and firing-fighting medium is flowed out from the small-caliber end of conical guiding sleeve 6, and transitional connection pipe 5 connects close to long bobbin
Several air admission holes 52 are evenly distributed on one end of female connector, which is connected to long bobbin 9.Firing-fighting medium is first through flow straightener
Conical guiding sleeve 6 is flowed into after 4 shuntings, because the water outlet of conical guiding sleeve 6 is gradually reduced, the flow velocity and hydraulic pressure of outlet are opposite to be increased
Greatly, at this point, tube fluid drives surrounding air-flow to form internal and external pressure difference, surrounding air-flow passes through the air admission hole on transitional connection pipe 5
52 enter in long bobbin 9；When firing-fighting medium is foam, foam mixes in long bobbin 9 with windage, and is the long cylinder
9 length longest of gun tube has grace time to foam in long bobbin 9 by foam and generate a large amount of foam, most afterwards through on long bobbin 9
The nozzle 92 at end sprays.Likewise, when firing-fighting medium is water, outside air is entered from air admission hole 52 in long bobbin 9, gas
Stream is forming protective layer around the water column that conical guiding sleeve 6 flows out, make the global shape of water column during ejection not
It can be easy to be scattered.The water column flows through taper guide pipe 6, so that flow velocity is increased, hydraulic pressure increase, water column is made to have before ejection centainly
Pressure and flow velocity, to which range can be improved；In addition, the transitional connection pipe 5 is equipped with air admission hole 52, fluid is in long bobbin 9
