Background technology
Mortar is development in science and technology product to a certain extent, and it occurs existing century-old history, and the transmitting of mortar contains very complicated dynamic process, is also giving full play to and applying of physical principle.
Therefore, in order to learn the principle of work that mortar is launched, be necessary the mortar making a kind of teaching aid or toy-type, make it under the condition of low cost transmitting, just fully can simulate the principle of work of mortar transmitting, allow the physical principle that student and child launch at the process learning mortar played, arouse the interest in study, also can strengthen recreational.
Summary of the invention
The technical problem to be solved in the present invention overcomes the deficiencies in the prior art exactly, a kind of ingenious application Rafael nozzle principle of work is provided to carry out teaching aid or the toy-type mortar of air water injection, this mortar has the advantages that structure is simple, implementation cost is low, is particularly suitable for doing teaching aid or toy use.
For overcoming the deficiencies in the prior art, the present invention takes following technical scheme:
The manometric rubber plug of a kind of band is launched streamline empennage-type and directly to be sprayed water mortar, comprise launching tube and mortar body, it is characterized in that: launching tube top is provided with the transmitting lid of threaded engagement, launch in lid and have cone rubber plug, screw transmitting lid and can realize sealing, when launching cylinder pressure and being enough large, cone rubber plug can quick-fried spray out, and repeatedly can assemble use; Launching tube inner wall smooth is also connected with tensimeter, and bottom is provided with valve input compressed-air, and launching tube bottom is provided with centre of location stake and carries out nested type centralized positioning to the bottom spout of inserting mortar; Plastic cement spheroid is arranged at mortar body top, microclearance Air-tight piston formula can be carried out slide in smooth launching tube, plastic cement spheroid upper middle position has through hole and check valve sheet, through hole can realize air inlet and pour water, check valve sheet can be carried out unidirectional control and be realized closing sealing, similar basketball valve under positive pressure; The firm airtight connection outer tube in spheroid bottom, outer tube has center tracheae, and center tracheae inserts in spheroid, and center tracheae Minimal Tension is closed and realized sealing and be connected by the contraction elasticity of spheroid through hole plastic cement, can conducting when having an interior pressure; Outer tube bottom is that inwall first expands the air water jet pipe reduced again, tracheae lower end, center is conical, and to be provided with aperture be pressurized air spout, the coaxial embedding outer tube of center tracheae non-fully contact, formed in outer tube and between pipe core and bore tubular throttling aquaporin and daraf(reciprocal of farad) that curved surface expansion chambers, your curved surface expansion chambers of daraf(reciprocal of farad) is the mixing chamber that pressurized air and pressure (hydraulic) water enter simultaneously, and gas-water mixture is by the bottom spout high velocity jet of mortar; The outer wall of outer tube bottom is provided with streamline empennage.
Described launching tube is flexibly connected bracing frame.
The present invention mainly carries out the optimal design of air water mortar by flexible Application Rafael nozzle principle of work, can fly get Geng Gao, farther to realize air water mortar.
The principle of work of Rafael nozzle is such: the jet pipe of band trunnion, classical fluid mechanics is followed when pressure gas first progressively enters the narrowest and small throat's process by the pipe position that cross section is larger, cross section diminish flow velocity increase, resistance also significantly increases sharply, form the flowing of a kind of gas throttling, but the convergent divergent channel part that pressure gas progressively expands by entering cross section after throat's smallest cross-sectional, due to the decompressional expansion of pressure gas, gas no longer follows Classical Fluid Mechanics, but can be sprayed by convergent divergent channel with very high speed, if compression pressure is enough high and nozzle structure is reasonable, gas can spray from spout with supersonic speed.Rafael nozzle principle of work is applied to jet airplane and mortar, significantly improves efficiency and the power of jet engine, achieves space flight, the leaping of science and technology of aviation.
The present invention is that the principle of work of application Rafael nozzle carries out mixing wastewater with air high velocity jet, and can realize the most rational Conversion of Energy, what mortar was flown is far, and its course of work is such:
1, the spheroid of mortar body is poured into suitable quantity of water, water level is the highest, and to be no more than center tracheae suitable for reading, assembles and adjust angle just can connect valve and carry out compressed-air actuated input, now progressively can be full of pressurized air in launching tube and mortar body;
2, when pressure increase is to when making that cone rubber plug is quick-fried to be sprayed out, the air pressure of mortar spheroid front end reduces to atmospheric pressure instantaneously, and spheroid bottom pressurized air is then rapid as shell is launched, by mortar body outburst injection, valve block can be closed rapidly under interior pressure effect, realizes one-level and launches;
3, streamline empennage can control mortar stabilized flight, spheroid compressed air is by the ejection of tracheae lower end, center spout simultaneously, retaining in compressed air-driven spheroid enters outer tube by elasticity open gaps between spheroid and center tracheae and carries downwards, finally enter mixing chamber together from lower end cone tubular throttling passage, due to daraf(reciprocal of farad) that effect, pressurized air expansion driven mixing wastewater with air is also spouting from spout at a high speed, obtain powerful recoil power, the second motive force realizing water mortar sprays, and makes it to fly get Geng Gao, farther.
In order to mortar body compressed air potential energy is converted into injection power most effectively, it is optimal state that air water has sprayed simultaneously; Pipe throttle can make air water optimal proportion mixing jetting, can realize top efficiency and strong impetus is flown, and supports to fly get Geng Gao, farther.
Compared with prior art, beneficial effect of the present invention is also:
Ingenious achieve pressure launch with one stage of compression air launch flight; The ingenious two-stage ignition flight simulating mortar of two-stage injection flight; Also ingeniously merge classical Rafael nozzle principle to promote experimental level and to promote student to the perception of science, make mortar fly get Geng Gao, farther; Streamline empennage also has spinfunction; To rubber plug by dip in water or smear suds carry out lubrication can change ejection friction force regulate the quick-fried power of spraying.
Apparatus of the present invention structure is simple, reliable, ingenious, cost is low, has good operability and Science Explorations intelligence development characteristic, is the teaching aid and toy that practicality is very strong.
