Description
Technical field
The present invention relates to a kind of teaching aid or toy, refer specifically to compel with the integral empennage-type direct-injection water of manometric rubber stopper transmitting
Hit big gun.
Background technology
Mortar is the product of development in science and technology to a certain extent, and it goes out the history that there is now up to a hundred years, the transmitting of mortar
Sufficiently complex dynamic process is contained, is also giving full play to and applying for physical principle.
Therefore, in order to learn mortar transmitting operation principle, it is necessary to make the mortar of a kind of teaching aid or toy-type,
It just can be fully simulated the operation principle of mortar transmitting under conditions of low cost transmitting, allow student and child in object for appreciation
The physical principle of process learning mortar transmitting, excites learning interest, can also strengthen recreational.
The content of the invention
The technical problem to be solved in the present invention is exactly to overcome the deficiencies in the prior art to be sprayed there is provided a kind of ingenious application daraf(reciprocal of farad) that
Pipe operation principle carries out the teaching aid or toy-type mortar of air water injection, and this mortar has simple in construction, implementation cost low
The characteristics of, it is particularly suitable for making teaching aid or toy is used.
To overcome the deficiencies in the prior art, the present invention takes following technical scheme：
It is a kind of to launch integral empennage-type direct-injection water mortar, including launching tube and mortar body with manometric rubber stopper,
It is characterized in that：Launching tube top, which is provided with the transmitting lid that screw thread coordinates, transmitting lid, cone rubber plug, screws transmitting Gai Keshi
Now seal, when launch cylinder pressure it is sufficiently large when, cone rubber plug can be sprayed open with quick-fried, and can repeatedly be assembled and used；Launching tube
Inner wall smooth is simultaneously connected with pressure gauge, and bottom inputs compressed air provided with valve, and launching tube bottom is opposed provided with centre of location stake
The bottom spout for entering mortar carries out nested type centralized positioning；Plastic cement spheroid is arranged at mortar body top, in smooth launching tube
Interior energy carries out microgap Air-tight piston formula and slided, and plastic cement spheroid upper middle position has a through hole and check valve sheet, and through hole can be with
Air inlet is realized with pouring water, check valve sheet can carry out unidirectionally controlled and closing sealing, similar basketball gas are realized under positive pressure
Mouth；The firm airtight connection outer tube in spheroid bottom, outer tube has in center tracheae, center tracheae insertion spheroid, spheroid
The contraction elasticity of through hole plastic cement, which closes center tracheae Minimal Tension, realizes sealing linking, and having can turn on during internal pressure；Under outer tube
Portion is that inwall first expands the air water jet pipe reduced again, and center tracheae lower end is cone, and is compressed air spout provided with aperture,
The coaxially embedded outer tube of the non-full-contact of center tracheae, forms the interior cone cylinder shape throttling aquaporin between central tube of outer tube and daraf(reciprocal of farad) that
Curved surface expansion chambers, your curved surface expansion chambers of daraf(reciprocal of farad) are the mixing chamber that compressed air enters with pressure (hydraulic) water simultaneously, and gas-water mixture passes through
The bottom spout of mortar sprays at a high speed；The outer wall of outer tube bottom is provided with integral empennage.
The launching tube is flexibly connected support frame.
The present invention mainly carries out the optimization design of air water mortar by flexible Application Rafael nozzle operation principle,
With realize air water mortar can fly get Geng Gao, it is farther.
The operation principle of Rafael nozzle is such：Jet pipe with trunnion, when compressed gas is first by the larger pipe in section
Position step into most narrow and small throat's process follow classics hydrodynamics, section diminish flow velocity increase, resistance it is also significantly fast
Speed increase, forms a kind of gas throttling flowing, but compressed gas is by entering the expansion that section progressively expands after throat's smallest cross-sectional
Tube portion is opened, due to the decompressional expansion of compressed gas, gas no longer follows Classical Fluid Mechanics, but can be with very high speed
Sprayed by expansion pipe, if compression pressure is sufficiently high and nozzle structure is reasonable, gas can be sprayed with supersonic speed from spout.Draw
Fa Er jet pipes operation principle is applied to jet airplane and mortar, greatly improves the efficiency and power of jet engine, realizes
Space flight, science and technology of aviation are leapt.
The present invention is to carry out mixing wastewater with air using the operation principle of Rafael nozzle to spray at a high speed, and most rational energy can be achieved
Amount conversion, makes the far of mortar flight, its course of work is such：
1st, the spheroid of mortar body is poured into suitable quantity of water, water level not more than center tracheae is suitable for reading, assembles and adjusts
Good angle is compressed the input of air with regard to that can connect valve, and now launching tube is empty with can progressively be full of compression in mortar body
Gas；
2nd, when pressure, which rises to, makes that cone rubber plug is quick-fried to be sprayed out, the air pressure moment of mortar spheroid front end is reduced to greatly
Air pressure, spheroid bottom compressed air then the rapid transmitting such as shell, mortar body is broken out and projected, valve block is made in internal pressure
It can rapidly be closed under, realize that one-level is launched；
3rd, integral empennage can control mortar stabilized flight, while spheroid compressed air is sprayed by center tracheae lower end
Mouthful spray, the retaining in compressed air-driven spheroid by elastic open gaps between spheroid and center tracheae enter outer tube to
Lower conveying, finally enters mixing chamber together from lower end cone cylinder shape throttling passage, due to daraf(reciprocal of farad) that effect, compressed air expansion driven
Mixing wastewater with air is simultaneously spouting from spout at a high speed, obtains strength recoil power, realizes the second motive force injection of water mortar, is allowed to
Fly get Geng Gao, farther.
In order to which mortar body compressed air potential energy is most effectively converted into injection power, it is most to manage that air water has sprayed simultaneously
The state thought；Pipe throttle can make air water optimal proportion mixing jetting, it is possible to achieve peak efficiency is flown with strong impetus, support
Fly get Geng Gao, farther.
Compared with prior art, beneficial effects of the present invention are also resided in：
It is ingenious to realize pressure transmitting and the ejection flight of one stage of compression air；Two-stage injection flight is ingenious to simulate mortar
Two-stage ignition flight；It is also ingenious to have merged classical Rafael nozzle principle to lift experimental level and lifting student to science
Perception, mortar is flown get Geng Gao, farther；Ejection can be changed by dipping in water or smearing suds and be lubricated to rubber stopper
Frictional force adjusts the quick-fried power of spraying.
Apparatus of the present invention are simple in construction, reliable, ingenious, cost is low, with good operability and Science Explorations intelligence development
Characteristic, is practicality very strong teaching aid and toy.
