Embodiment Construction

[0010] A structural schematic diagram of a launching device using compressed gas as energy, such as figure 1 shown. The device is divided into two parts, a launch tube 1 and a pneumatic valve (3-14), which are connected through a connecting sleeve 2 and sealed with an O-ring.

[0011] The upper and lower ends of the pneumatic valve are respectively provided with an air storage chamber 6 and a valve actuating air chamber 8, and are independent of each other. The air storage chamber 6 is composed of the upper valve body 4, the valve 3 and the top of the lower valve body 9. The upper end and the side wall of the upper valve body 4 respectively have a working air outlet and an air storage chamber inlet / outlet 5, and the working air outlet passes through The valve 3 is sealed; the valve moving air chamber 8 is composed of the lower valve body 9, the spring 13 and the piston 12, the piston 12 and the lower valve body 9 are sealed by an O-ring, and the upper end and the side wall of...

Abstract

The invention relates to a launcher, specifically an object launching device with compressed gas as energy which is appropriate for fireworks ejection and object throwing. 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 [0001] The invention relates to a launching device, in particular to an object launching device which uses compressed gas as the energy source and is suitable for fireworks projectile ejection and object ejection. Background technique [0002] Due to factors such as the difficulty and cost of engineering realization, the energy used for launching objects with different requirements in different fields is different. For example, objects such as shells and bullets require a high firing velocity (10 3 m / magnitude), usually with explosives such as gunpowder or propellant to achieve. And the requirements for the launch speed are lower (10 2 m / order or lower), its energy source options are very wide, such as slingshots generally use the chemical energy stored in the human body. [0003] At present, gunpowder is mostly used as the energy source for launching fireworks. When launching, the gunpowder generates a certain amount of gas to push the fireworks to move i...
