22；The sealing-plug 21 is connected by several elastic webbings 23 being circularly and evenly distributed with 16 inner wall of the second bellmouth；It is described
Sealing-plug 21 is equipped with a up-narrow and down-wide rectification hole 24.
Several equally distributed sealing holes 25 are equipped in the supercharging column 14, sealing hole 25 connects with transverse flow channels 20；
25 top of the sealing hole is equipped with the third bellmouth 26 to connect with it, and third bellmouth 26 is in up-narrow and down-wide shape；Described
26 upper port of triconic hole connects with the first bellmouth 15；The port that the sealing hole 25 connects with third bellmouth 26 is set
There is a sealing ring 27；The fixed ring 28 coaxial with sealing ring 27 is fixed in the third bellmouth 26；The fixed ring 28 connects
It is connected to the second volute spring 29；Second volute spring, 29 free end is connected with sealing bar 30；The sealing bar 30 passes through close
27 endoporus of seal ring is connected with the sealing plate 31 in sealing hole 25.
The application method of the utility model is as follows：
Before using fire extinguisher, 3 position of handle is held, then hand presses down on press handle 4, at this time press handle
4 can press down on valve rod, and valve rod 8 moves down, the opening and closing element 12 being connected with valve rod 8 then no longer with open and close 9 top of hole
Inner wall fits, and opens and closes hole 9 and opens, and the extinguishing chemical in fire extinguisher bottle body will pass sequentially through spiro union portion 2, open and close hole 9 and defeated
Hole 5 is sent, squit hole 6 is and then flowed into, is finally sprayed from jet pipe 7, for fire extinguishing.
When fire extinguisher bottle internal pressure is normal, a part of extinguishing chemical will be on sealing-plug 21 under the action of high pressure gas
Top, makes sealing-plug 21 enter in the first bellmouth 15, and connecting hole 17 opens wide completely, which passes sequentially through the second cone
Shape hole 16, connecting hole 17 and the first bellmouth 15, another part extinguishing chemical can then enter in longitudinal hole 18, and in high pressure
It is under effect that pressure plare 19 is open-top, so that the extinguishing chemical in longitudinal hole 18 is entered the first bellmouth from 18 upper port of longitudinal hole
In 15, which equally has some and is entered in connecting hole 17 by the port of transverse flow channels 20, it follows that
In the case of high pressure, the extinguishing chemical in fire extinguisher bottle body can all be converged in the first bellmouth, finally all be entered by opening and closing hole 9
In sprocket hole 5, until sprayed from jet pipe 7, therefore even if extinguishing chemical is connected hole 17 and multiple longitudinal holes during outflow
18 shuntings, the fire extinguishing agent content that last jet pipe sprays can be protected always.
When fire extinguisher bottle internal pressure becomes it is small when, air pressure at this time sealing-plug 21 can not then be formed enough pressure with
And pressure plare 19 can not be pushed upwards, sealing-plug 21 is refilled under the effect of elastic webbing 23 in connecting hole 17, with
The reset of sealing-plug 21, sealing-plug 21 all blocks several ports of transverse flow channels, and pressure plare 19 then can be under natural gravity
It resets, lid is closed in 18 upper port of longitudinal hole again, therefore enters the extinguishing chemical of the second bellmouth 16 only out of fire extinguisher bottle body
It can be flowed into the first bellmouth 15 by the rectification hole 24 on sealing-plug 21, since rectification hole 24 is in up-narrow and down-wide shape, with
For extinguishing chemical closer to the first bellmouth 15, the position diameter that extinguishing chemical flows through is just smaller, the same traffic the case where, with aperture
It constantly narrows, the air pressure mixed with extinguishing chemical can be then squeezed, and air pressure is made to be increased, and form high pressure again, and gone out
Before fiery agent flows into rectification hole 24 from the second bellmouth 16, the second bellmouth 16 can then first pass through the up-narrow and down-wide structure of itself
First of supercharging is formed, it being capable of maximum journey after being rectified the supercharging of hole 24 again by 16 extinguishing chemical after supercharged of the second bellmouth
On degree ensure extinguishing chemical pressure, so that the extinguishing chemical sprayed from jet pipe 7 is obtained enough dynamics, eject it is extremely remote away from
From, with the guarantee of extinguishing chemical jet length, even if user of service keeps fire away, extinguishing chemical can equally be sprayed to burning things which may cause a fire disaster,
The intensity of a fire is set to be controlled, the overlength distance between user of service and burning things which may cause a fire disaster has effectively prevented security risk, and user of service is enabled to go out
It during fire, will not be injured by the intensity of a fire, ensure that the personal safety of user of service.
When fire extinguisher bottle internal pressure is normal, air pressure can then push sealing plate 31, on sealing plate 31
It moves, sealing plate makes to enter the extinguishing chemical being pressurized in column 14 and air-flow can only be from longitudinal direction eventually by the inner reversible cycle of sealing ring
The upper port in hole 18 flows out, if fire extinguisher bottle internal pressure is reduced, gas can not then obtain enough pressure, and at this time second
29 elastic force of volute spring makes sealing plate 31 reset, and sealing plate 31 can not block the endoporus of sealing ring 27, extinguishing chemical and gas
Body can be then flowed by 27 endoporus of sealing ring in third bellmouth 26, since third bellmouth 26 is in up-narrow and down-wide shape,
Extinguishing chemical then can be further pressurized, and extinguishing chemical after supercharged can then enter in the first bellmouth 15, and from rectification hole 24
The extinguishing chemical for entering the first bellmouth 15 is mixed, and multiple tracks extinguishing chemical is converged after being all pressurized, and can be carried out each other
It drives, improves the injection dynamics of extinguishing chemical when spraying to the full extent, and the first bellmouth 15 is in shape with wide top and narrow bottom, more conducively
The convergence of multiple tracks extinguishing chemical, and 26 upper port of third bellmouth connects with the first bellmouth 15, the taper of the first bellmouth 15
Inner wall can be effectively increased area, the more conducively setting of 26 upper port of third bellmouth, can be effectively increased third bellmouth 26
Number, improve supercharging effect.
