Abstract
The utility model relates to a launching device, especially an object launching device applied to fireworks shell launch and object throw which take compressed gas as energy source. The launcher of the device is connected with a pneumatic valve by a connecting sleeve and the pneumatic valve takes compressed gas as power source. The upper and the lower ends of the pneumatic valve are provided with a gas storage chamber and a valve motion gas chamber respectively; wherein, the two chambers are independent each other. The side walls of the two chambers both are provided with gas inlets and gas outlets. A valve handle is in fixed connection with a valve and a piston and passes through the gas storage chamber and the valve motion gas chamber. A spring is located in the ring step of the valve motion gas chamber. An optional valve cover is provided with an accelerating gas inlet and an accelerating gas outlet. An accelerating gas chamber is composed of the optional valve cover, a lower valve body and the piston to accelerate the motion of the piston and the valve. Taking the compressed gas as power source can avoid the environmental pollution effectively and improve visibility. Using large flow quick-response pneumatic valve can reduce air supply pressure of the launching device and improve security of the device at the same time. The integrated design of the launching tube and the pneumatic valve simplifies the launching device and reduces volume of the launching device.
Description
Technical field
The utility model relates to a kind of emitter, and 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 purpose of this utility model has been to provide a kind of effective solution emitter to produce the approach of this problem of dusty gas, and it is the energy with the Compressed Gas, and can reuse non-maintainingly.
Realize the technical solution of the utility model: a kind of is the object emitting device of the energy with the Compressed Gas, and launching tube is connected with pneumatic operated valve, and 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.Valve rod and valve and piston connect firmly, and pass gas dome and valve actuation air chamber.Spring is positioned at the ring-shaped step of valve actuation air chamber.Optional valve gap offers and quickens/gas outlet, and it forms the acceleration air chamber with following valve body and piston, with the motion of accelerating piston and valve.
Effect of the present utility model: 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 object emitting device 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 object emitting device 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.
