A canister launcher thereof is connected with a pneumatic valve with compressed gas as power source through a connecting sleeve; upper and lower ends of the pneumatic valve are provided with independent gas dome and valve actuation gas chamber; side wall of both has gas inlet/outlet holes; a valve stem is connected with a valve and a piston fixedly and penetrates the gas dome and the valve actuation chamber; a spring is located in a circular step of the valve actuation gas chamber; a selectable valve cap is provided with acceleration gas inlet/outlet hole to compose an acceleration gas chamber with a lower valve and the piston so as to accelerate motion of the piston and the valve; with compressed gas (such as air, nitrogen) as the power source, the invention can effectively avoid environment pollution; with the large capacity fast response pneumatic valve, the invention can reduce air feed pressure of the launcher, and improve safety of equipment; the transmitting valve is designed integrated with the pneumatic valve so as to simplify launching device and reduce volume thereof.
Description
Technical field
The present invention relates to a kind of emitter, particularly a kind of what be applicable to fireworks cartridge ejection, object impelling is the object emitting device of the energy with the Compressed Gas.
Background technology
Be limited to factors such as the difficulty of Project Realization and cost, the different objects that require of different field are launched used energy difference.For example, object such as shell, bullet requires to have very high emission rate (10
3The m/s magnitude), realize with priming systems such as gunpowder or propellants usually.And require lower by (10 for emission rate
2M/s magnitude or lower) emitter, its energy is selected then very extensive, and for example catapult generally uses the chemical energy that human body stores.
At present, the emission of fireworks bullet is many to be the energy with the gunpowder, and during emission, gunpowder produces a certain amount of combustion gas promotion fireworks bullet and moves in transmitting tube, and emission rate is controlled by the number of gunpowder.Its shortcoming is that ground produces a large amount of dusty gas, reduces control-tower visibility.
Summary of the invention
The object of the present invention is to provide a kind of effective solution emitter to produce the approach of this problem of dusty gas, it is the energy with the Compressed Gas, and can reuse non-maintainingly.
Realize technical scheme of the present invention: a kind of is the emitter of the energy with the Compressed Gas, it is characterized in that: launching tube is connected with pneumatic operated valve, pneumatic operated valve adopts Compressed Gas as power source, described pneumatic operated valve upper and lower side is established separately independently gas dome and valve actuation air chamber respectively, and the sidewall of two Room all offers into/gas outlet.
The valve rod of described pneumatic operated valve passes gas dome and valve actuation air chamber, its two ends respectively with gas dome on valve and the piston under the valve actuation air chamber connect firmly, spring is positioned at the ring-shaped step of valve actuation air chamber.
Described gas dome is made of the top of upper valve body, valve and following valve body.
Described valve actuation air chamber is by valve body and piston constitute down.
The described bottom of valve body down is provided with valve gap, offers on the valve gap and quickens/gas outlet, and valve gap is formed the acceleration air chamber with following valve body and piston.
Effect of the present invention: adopt Compressed Gas (as air, nitrogen) as power source, can effectively avoid pollution to environment; Adopt big flow to respond operated pneumatic valve fast, can reduce the air feed pressure of transmitter, the security that has also just improved equipment simultaneously; Transmitter is simplified in transmitting tube and operated pneumatic valve integrated design, dwindles the transmitter volume.This device is used for the emission of fireworks bullet, and can avoid with the pyrotechnic compound is the pollution that the emission of the energy brings, and especially indoor fireworks display or rainy weather performance improve visibility, make performance have more ornamental value.This device also can be used for the emission of other objects.
Description of drawings
Fig. 1 for a kind of be the structural representation of the emitter of the energy with the Compressed Gas.
Among the figure: 1. transmitting tube; 2. adapter sleeve; 3. valve; 4. upper valve body; 5. gas dome advances/gas outlet; 6. gas dome; 7. valve actuation is advanced/gas outlet; 8. valve actuation air chamber; 9. descend valve body; 10. quicken/gas outlet; 11. valve gap; 12. piston; 13. spring; 14. valve rod.
The specific embodiment
A kind of is the structural representation of the emitter of the energy with the Compressed Gas, as shown in Figure 1.This device divides transmitting tube 1 and pneumatic operated valve (3～14) two parts, and connects by adapter sleeve 2, seals with O shape circle.
The pneumatic operated valve upper and lower side is established gas dome 6 and valve actuation air chamber 8 respectively, and independent separately.Gas dome 6 is made of the top of upper valve body 4, valve 3 and following valve body 9, and the upper end of upper valve body 4 and sidewall are opened a work gas outlet respectively and gas dome advances/gas outlet 5, and the work gas outlet is by valve 3 sealings; Valve actuation air chamber 8 is made of following valve body 9, spring 13 and piston 12, and 9 of piston 12 and following valve bodies pass through seal with O ring, and the upper end of following valve body 9 and sidewall are opened a stem through-hole respectively and valve actuation is advanced/gas outlet 7; Valve rod 14 runs through gas dome 6 and valve actuation air chamber 8 and by seal with O ring, isolation, its upper end connects firmly by screw thread and valve 3, and there is external screw thread its lower end and connects firmly and pass through seal with O ring by nut and piston 12; Spring 13 is positioned at valve actuation air chamber 8, and valve rod 14 runs through wherein; Following valve body 9 and piston 12 are provided with ring-shaped step, help the volume that spring 13 location also can reduce valve actuation air chamber 8.
Valve gap 11 is selectable units, and it and 12 times valve bodies of piston 9 form an acceleration air chamber and by seal with O ring, its bottom is opened one and quickened/gas outlet 10.
Is that the energy is realized the object emission with the Compressed Gas, such as with air, nitrogen as working medium, can avoid pollution, and can realize the heavy caliber emitter environment.This work relationship of installing between each parts is: will be launched object and pack in the transmitting tube 1, by valve actuation advance/the 7 pairs of valve actuation air chambers 8 in gas outlet inflate on request, and close valve actuation and advance/gas outlet 7; By gas dome advance/the 5 pairs of gas domes 6 in gas outlet inflate on request, and close gas dome and advance/gas outlet 5.Open valve actuation during emission and advance/gas outlet 7, gas pressure intensity reduces rapidly in the valve actuation air chamber 8, and gas promotes valve 3 motions in the gas dome 6, and valve 3 is opened, and gas promotes to be launched object accelerated motion in transmitting tube 1 in the gas dome 6, and object is launched away.Advance in valve actuation in case of necessity/when open gas outlet 7, by quicken/gas outlet 10 inflates, accelerating piston 12 and valve 3 motions are to realize the quick response of valve.If ready back cancellation emission, at first opening gas dome advances/gas outlet 5 venting, and then open valve actuation advance/the gas outlet venting gets final product.
