Problems solved by technology

At present, the main way to extinguish forest fires is to use aircraft to spray fire extinguishing agent. However, due to the extremely complicated air flow over the fire field, the aircraft cannot approach the fire field. The fire extinguishing agent can only be released at a height of several hundred meters from the fire field, so that the fire extinguishing agent cannot directly act on the fire source. not ideal
In the military, many liquid warfare agents are sprayed by explosion, but the cloud formed by the explosion has the disadvantages of difficult to control the shape of the cloud, a large hole in the center of the cloud, easy to form a mushroom cloud, and difficult to achieve directional concentrated spraying. Directional spraying of certain liquid warfare agents (such as lubricants and adhesives) that require high spraying effects

Abstract

The present invention provides a liquid high speed spraying device, which uses solid propellant, gunpowder or gas propellant as power source and fuel gas with high pressure from the burn of agents spray from the nozzle to form high speed liquid jet with some spraying angle. The spraying device comprises gas generator, copper seal membrane, piston, liquid storage room and nozzle. All the agents has the characters of large gas product, quick speed, stable burn and easy to store for long term, to make liquid form moment stable jet, and benefit to device miniaturization for liquid spraying bomb with small volume. The jet from this device has the advantages of quick speed, good distribution, well direction and easy control cloud shape.

Description

Technical field [0001] The invention relates to a liquid high-speed spraying device. In particular, it is a high-pressure gas-driven liquid high-speed spraying device generated by the combustion of solid propellant, gunpowder or gas generating agent. technical background [0002] The technology of using pyrotechnic gas to implement high-speed directional pressure spraying and atomization of liquid can be widely used in military, industrial and agricultural production. For example, in fire protection engineering, high-speed directional spraying technology can be used to quickly release a large amount of fire extinguishing materials into the fire scene, forming a large-scale rapid suppression of fire, so as to achieve the purpose of rapid fire extinguishing. In agricultural production, using this kind of dispersion method to spray pesticides into farmland can achieve the purpose of eliminating pests in a large area. In addition, in modern military warfare, many new concept w...
