Description
Technical field
The present invention relates to a kind of teaching aid or toy, the foaming bung for referring specifically to identify with angle launches six symmetrical empennage-type rotations
Water spray mortar.
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 six symmetrical empennage-type churning water mortars with the foaming bung that angle is identified, including launching tube is hit with compeling
Monitor body, it is characterised in that：Launching tube is flexibly connected support frame, and launching tube is provided with the angle coordinated with support frame and identified；Transmitting
Cylinder top, which is provided with the transmitting lid that screw thread coordinates, transmitting lid, taper foaming bung, screws transmitting lid and sealing can be achieved, work as launching tube
When interior pressure is sufficiently large, taper foaming bung can be sprayed open with quick-fried, and can repeatedly be assembled and used；Launching tube bottom is inputted provided with valve
Compressed air, launching tube bottom carries out nested type centralized positioning provided with centre of location stake to the bottom spout for inserting mortar；Compel
Hitting monitor body top has plastic cement spheroid, and microgap Air-tight piston formula can be carried out in smooth launching tube and is slided, plastic cement spheroid
Upper middle position has through hole and check valve sheet, and through hole can realize air inlet with pouring water, and check valve sheet can carry out unidirectionally controlled
And closing sealing, similar basketball valve are realized under positive pressure；The firm airtight connection outer tube in spheroid bottom, outer tube has
In center tracheae, center tracheae insertion spheroid, the contraction elasticity of spheroid through hole plastic cement closes center tracheae Minimal Tension
Sealing linking is realized, having can turn on during internal pressure；Outer tube bottom is that inwall first expands the air water jet pipe reduced again, air water jet pipe water
Nozzle is provided with rotary fluid, and the inwall of rotary fluid is carved with helicla flute, and center tracheae lower end is cone, and is compression provided with aperture
Air port, the coaxial embedded outer tube of the non-full-contact of center tracheae forms the interior cone cylinder shape throttling water between central tube of outer tube and led to
Road and daraf(reciprocal of farad) that conical surface expansion chambers, your conical surface expansion chambers of daraf(reciprocal of farad) are the mixing chamber that compressed air enters with pressure (hydraulic) water, air water simultaneously
Mixture is sprayed at a high speed by the bottom spout of mortar；The outer wall of outer tube bottom is provided with six symmetrical empennages.
Altitude scale is provided with the spheroid.
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 taper foaming bung 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, six symmetrical empennages can control mortar stabilized flight, while spheroid compressed air passes through under the tracheae of center
Spout is held to spray, the retaining in compressed air-driven spheroid enters outer by elastic open gaps between spheroid and center tracheae
Pipe conveying downwards, enters mixing chamber by rotary fluid from lower end cone cylinder shape throttling passage eddy flow, and due to daraf(reciprocal of farad) that effect, compression is empty
Gas expansion driven mixing wastewater with air is simultaneously spouting from spout at a high speed, obtains strength recoil power, realizes that two grades of water mortar are moved
Power is sprayed, and 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；Foaming bung moderate pressure, is adapted to toy and teaching aid is used, without potential safety hazard.
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.
