Pad 11；Gasket 11 is arranged on the front end of piston rod 3, to the contact site of the front end of piston rod 3 and emission port 16 into
Row sealing.
In order to further increase airtightness, further includes: sealing ring 12；Bottom and the cylinder of piston rod 3 is arranged in sealing ring 12
Between the inner wall of body 1.
In order to be measured to the air pressure in cylinder body 1, further includes: survey splenium part 13；There is pressure tap on cylinder body 1；Survey pressure
Component 13 is arranged at pressure tap.
In the present embodiment, surveying splenium part 13 is pressure gauge.Elastomeric element 2 is spring.
When pneumatic type emitter provided by the embodiment of the utility model when in use, by air inlet 14 and high pressure gas cylinder phase
Even, power of jettisoninging is provided by high pressure gas cylinder.Exhaust valve 4 may connect to trigger, thus by the carrier for being loaded with deliverance apparatus jettisoning to
Target position.
In order to realize the automatic feedback regulatory function of the utility model embodiment, further includes: controller；The signal of controller
Input terminal is connect with the signal output end signal for surveying splenium part 13, and the signal output end of controller and the signal of high pressure gas cylinder input
End signal connection, to the pressure for the gas for being passed through cylinder body 1 be adjusted, to achieve the purpose that required air pressure.
The working principle for being divided to two states to be specifically described pneumatic type emitter provided by the embodiment of the utility model below:
One) high pressure gas imports, and device is in state of pressure keeping.
Referring to fig. 2, high pressure gas imports cylinder body 1 from air inlet 14, is divided into the road A and two, the road B trend.
The gas of the road A trend imports pressure gauge and big cylinder 9, can read the pressure in cylinder body 1 by pressure gauge at this time
Data, big cylinder 9 is interior to be full of high pressure gas.
The gas of the road B trend imports small cylinder 7, and exhaust valve 4 is closed at this time, is full of high pressure gas in small cylinder 7.At this point,
The state of relative equilibrium is in cylinder body 1.
Two) 4 stress of exhaust valve, device are in exhaust condition.
Referring to Fig. 3, apply an external force F to exhaust valve 4, the spring stress inside exhaust valve 4 is shunk, in small cylinder 7
High pressure gas is outwardly discharged from exhaust outlet 15, and pressure moment reduces, and is still high pressure gas in big cylinder 9 at this time, therefore
Under the action of this high pressure gas, the bottom of extrusion piston bar 3 is moved to partition 5, and spring is under pressure contraction, and cavity 8 gradually contracts
Small, big cylinder 9 gradually expands, and the front end of piston rod 3 is separated with emission port 16, at this point, the high pressure gas moment in big cylinder 9
It is sprayed by route C and route D, generates a very big forward thrust, the object emission jettisoninged will be needed to go out.
[technical effect]
1, there is partition 5 in cylinder body 1；One end of elastomeric element 2 is connect with partition 5, the other end and piston of elastomeric element 2
The bottom of bar 3 is connected to；There is cavity 8 between partition 5 and the bottom of piston rod 3；The front end of piston rod 3 and the transmitting of cylinder body 1
Mouth 16 contacts；Exhaust valve 4 is arranged at the exhaust outlet 15 of cylinder body 1；Have on partition 5 for being connected to exhaust outlet 15 and cavity 8
Through-hole 6.When in use, high pressure gas is passed through from the air inlet 14 of cylinder body 1, the air pressure of high pressure gas is significantly larger than 1 big
Air pressure, high pressure gas are spread into cylinder body 1 rapidly, and high pressure gas enters between cylinder body 1,5 side of partition and piston rod 3 all the way
Region, another way high pressure gas enter the region of cylinder body 1 Yu 5 other side of partition.At this point, generated in cylinder body 1 very high pressure and
Gas is balance.When being vented by exhaust valve 4, piston rod 3 is mobile to partition 5 rapidly under the action of high pressure, high pressure gas
Body is discharged from emission port 16, so that emitting substance be projected rapidly, thus solves and responds slower technical problem in the prior art,
Realizing can instantaneously pressurize and launch the technical effect with high speed.
2, guide rod 10 is arranged in cylinder body 1, and limits and connects with piston rod 3, the stretching motion of piston rod 3 is carried out
Guiding, it is therefore prevented that 3 sideslip of piston rod improves emission effciency.
3, gasket 11 is arranged on the front end of piston rod 3, improves airtightness, it is therefore prevented that the gas in cylinder body 1
It releases, further improves emission effciency.
4, there is pressure tap on cylinder body 1；It surveys splenium part 13 to be arranged at pressure tap, realize to the air pressure in cylinder body 1
Measurement.
5, by the use to controller, the automatic feedback regulatory function of the utility model embodiment is realized.
The utility model embodiment is made of stainless steel material, and air pressure is big, and required extraneous high pressure gas can dock city
General small gas cylinder, interchangeability are strong on field.Use the present apparatus as power, it may not be necessary to by any outside (power supply, gas source, fuel oil
Deng) power source device, it is particularly suitable for using in the case of the non-transformer of field.In addition, the utility model embodiment also has whole dress
Set the advantages such as small in size, portable, long service life, structure simple, easy processing, manufacturing cost be low.The utility model embodiment can
To be used for remote full-automatic water life-saving, fire-fighting and rescue, electric stringing, anti-terror assault, fight flood and relieve victims, rescue, ship on ice
