Description
Technical field
The present invention relates to a kind of teaching aid or toy, refers specifically to the rubber stopper with pressure gauge and launches six symmetrical empennage-type direct-injections
Water 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
Contain sufficiently complex dynamic process, and physical principle giving full play to and applying.
Therefore, in order to learn mortar transmitting operation principle, it is necessary to make a kind of mortar of teaching aid or toy-type,
It can under conditions of low cost is launched fully is simulated the operation principle of mortar 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 overcome the deficiencies in the prior art, there is provided a kind of ingenious application daraf(reciprocal of farad) that spray
Pipe operation principle carries out the teaching aid or toy-type mortar of air water injection, and this mortar has that simple in construction, implementation cost is low
The characteristics of, it is particularly suitable for making teaching aid or toy uses.
For overcome the deficiencies in the prior art, the present invention takes following technical scheme：
A kind of rubber stopper with pressure gauge launches six symmetrical empennage-type direct-injection water mortars, including launching tube and mortar
Body, it is characterised in that：Launching tube top is provided with the transmitting lid that screw thread coordinates, and has cone rubber plug in transmitting lid, screws transmitting lid
Sealing can be achieved, when transmitting cylinder pressure is sufficiently large, cone rubber plug can be opened with quick-fried spraying, and can assemble use repeatedly；Hair
Shooting cylinder inner wall smooth is simultaneously connected with pressure gauge, and bottom is provided with valve input compressed air, and launching tube bottom is provided with centre of location stake
Nested type centralized positioning is carried out to the bottom spout for inserting mortar；Plastic cement spheroid is arranged at mortar body top, in smooth hair

Air inlet can be realized with pouring water, check valve sheet can carry out unidirectionally controlled and closing sealing is realized under positive pressure, similar basket
Ball valve；The firm airtight connection outer tube in spheroid bottom, outer tube have center tracheae, and center tracheae is inserted in spheroid, ellipse
The contraction elasticity of spheroid through hole plastic cement, which closes center tracheae Minimal Tension, realizes sealing linking, and having can turn on during internal pressure；Outside
Pipe bottom is that inwall first expands the air water jet pipe reduced again, and center tracheae lower end is cone, and is compressed air provided with aperture
Spout, the coaxial embedded outer tube of the non-full-contact of center tracheae, formed in outer tube the cone cylinder shape central tube between throttle aquaporin and
Daraf(reciprocal of farad) that curved surface expansion chambers, the mixing chamber that your curved surface expansion chambers of daraf(reciprocal of farad) are compressed air simultaneously and pressure (hydraulic) water enters, mixing wastewater with air
Body 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.
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,
To realize that air water mortar can fly get Geng Gao, 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, form a kind of gas throttling flowing, but the expansion that compressed gas progressively expands by entering section 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

Amount conversion, mortar is set to fly far, 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, opens the quick-fried spraying of cone rubber plug, the air pressure moment of mortar spheroid front end is reduced to greatly
Air pressure, spheroid bottom compressed air then rapidly as shell transmitting are the same, mortar body are broken out and projected, valve block is in internal pressure work
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 water storage in compressed air-driven spheroid enters outer by elastic open gaps between spheroid and center tracheae
Pipe conveying downwards, finally from lower end, cone cylinder shape throttling passage enters mixing chamber together, due to daraf(reciprocal of farad) that effect, compressed air expansion
Drive mixing wastewater with air and high speed be spouting from spout, obtain strength recoil power, realize the second motive force injection of water mortar,
It 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, is supported
Fly get Geng Gao, farther.
Compared with prior art, beneficial effects of the present invention also reside 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, have good operability and Science Explorations intelligence development
Characteristic, it is practicality very strong teaching aid and toy.
