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
Affiliated technical field
The present invention relates to a kind of liquid at high speed flusher.Particularly a kind of high-pressure gas that adopts solid propellant, gunpowder or gas-forming agent burning to produce drives the liquid at high speed flusher.
Technical background
The technology of utilizing firework fuel gas that liquid is implemented sprinkling of high speed directed pressure and atomizing can be widely used in military affairs and the industrial and agricultural production.Such as in fire engineering, can utilize the directed spraying technology of high speed that a large amount of extinguish materials are discharged in the scene of a fire fast, fire is formed large-scale rapid inhibitory effect, thereby reach the purpose of rapid fire extinguishing.In agricultural production, utilize this type of dispersing mode, pesticide is sprayed in the farmland, just can reach the purpose of large tracts of land eliminating pest.In addition, in the modern military war, many new concept weapon are that the ammunition of main filling material all use the mode of pressure boundling spraying to finish filling material to disperse fast as efficient lubricated bullet, gluing bullet etc. with liquid.Put out forest fire at present and mainly use the airplane spray extinguishing chemical, but because the overhead air stream in the scene of a fire is complicated unusually, aircraft can't can only discharge extinguishing chemical at the hundreds of meters height in the distance scene of a fire near the scene of a fire, make extinguishing chemical can't directly act on burning things which may cause a fire disaster, the fire extinguishing effect is unsatisfactory.And in the military affairs, modes are shed in many employing blasts of shedding of many liquid war agent, but the cloud and mist that blast disperse to form exists, and the cloud and mist shape is restive, the cloud and mist center exists than macroscopic-void, easily form mushroom cloud, be difficult to realize the directed shortcoming such as sprayings of concentrating, and is not suitable for the orientation sprinkling of some liquid war agent (as lubricant, adhesive) that spray effect is had relatively high expectations.
Summary of the invention
The objective of the invention is provides a kind of liquid at high speed flusher in order to overcome deficiency of the prior art.It adopts solid propellant, gunpowder or gas-forming agent is power source, and the high-pressure gas that these medicament burnings produce drives liquid and sprays from nozzle, forms to have the high-velocity liquid jet of certain spreading of spray.The pyrotechnic gas generator is a kind of aerogenesis apparatus fast and safely, has that volume is little, gas production is big, inflation is fast, easy to use, be not subjected to advantage such as environmental influence, is a kind of comparatively desirable high-pressure air source.Pyrotechnic gas generator as the power source that liquid at high speed sprays, is applied to the liquid spraying device, is a kind of research thinking of innovation.
The technical solution adopted for the present invention to solve the technical problems is: the power source that this flusher adopts gas generator to spray as liquid at high speed.Flusher partly is made up of gas generator, red copper diaphragm seal, piston, liquid storeroom, nozzle etc.Gas-forming agent powder column in the gas generator adopts uiform section die casting, and starting mix is a black powder in the igniter, and sparking mode is the remote control electric ignition.Igniter is lighted starting mix and is ignited the gas-forming agent powder column after accepting to start the signal of telecommunication, the powder column burning produces high temperature and high pressure gas, when gas pressure reaches the Rupture of Membrane pressure of red copper diaphragm seal, gases at high pressure are broken through diaphragm seal and are entered the liquid storeroom, and promote the piston acting, and piston promotes liquid and breaks through nozzle sealing unit, and liquid sprays at a high speed from nozzle with certain spreading of spray, formation has the high-speed jet of certain spreading of spray, sprays to target.
The invention has the beneficial effects as follows:
1. the high-temperature high-pressure fuel gas that adopts solid propellant, gunpowder or gas-forming agent burning to produce is a power source.Liquid is accelerated to above 100m/s in the short time at the utmost point.
2. to have gas production big for solid propellant, gunpowder or gas-forming agent, and aerogenesis speed is fast, flameholding, is easy to characteristics such as long-term storage, makes liquid to form stable jet in moment, and help equipment miniaturization, can manufacture small volumes of liquids and spray bullet.
The spraying jet that forms of this flusher have speed fast, be uniformly dispersed, good directionality, cloud and mist shape advantage such as control easily.
