Abstract
The utility model discloses a demonstration teaching aid of boiling point and pressure, including bracing piece, base, alcohol burner and container bottle, be equipped with two bracing pieces and two alcohol burner recesses on the base, be connected with the cantilever between the bracing piece, be fixed with two container bottle on the cantilever, container bottle is equipped with water inlet, delivery port, pressure regulating mouth and thermometer, water inlet port department is hourglass hopper -shaped, and the water inlet neck is equipped with fastening bolt, the neck of delivery port is equipped with fastening bolt, the pressure regulating mouth is equipped with piston and fastening bolt, fastening bolt's bottom parcel has the soft rubber, and the soft rubber prevents the damage of fastening bolt to water inlet, delivery port and pressure regulating mouth neck portion, the utility model discloses a fastening bolt, piston and container bottle's cooperation can change the pressure in the bottle at any time, through the change of observing the thermometer, can very audio -visually see the boiling point of liquid and the relation between the pressure, and the experimental result that is equipped with two container bottle messengers simultaneously more has comparison nature.
Description
Technical field
This utility model relates to a kind of physical teaching aid, a kind of boiling point and the demonstration teaching aid of pressure.
Background technology
At present, boiling point and the lecture experiment of pressure, some employing needle tubings change the pressure in container, but people must be had to pin the piston of needle tubing specially, somewhat move and the relation of boiling point and the pressure observed will be made inaccurate, and the boiling point observed and the relation of pressure are the most rough, it is impossible to grasp the relation of boiling point and pressure the most accurately, and do not compare.
Utility model content
The purpose of this utility model is the demonstration teaching aid providing a kind of boiling point with pressure, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of boiling point and the demonstration teaching aid of pressure, including support bar, base, alcohol burner and container bottle；Described base is provided with two support bars and two alcohol burner grooves；Connect between described support bar and have cantilever；Two container bottle it are fixed with on described cantilever；Described container bottle is provided with water inlet, outlet, pressure modulating opening and thermometer；Described water inlet cervical region is provided with fastening bolt；The cervical region of described outlet is provided with fastening bolt, and two outlets link together；Described pressure modulating opening is provided with piston and fastening bolt.
As further program of the utility model: the bottom of described fastening bolt is all enclosed with soft rubber.
As further program of the utility model: be set to funnel-form at described inlet port.
As further program of the utility model: described piston base is made up of soft rubber.
Compared with prior art, the beneficial effects of the utility model are:
This utility model, by fastening bolt, piston and the cooperation of container bottle, can change the pressure in bottle at any time, by observing the change of thermometer, can see the relation between the boiling point of liquid and pressure the most intuitively；It is provided with the experimental result that two container bottle make and more has comparative.
Accompanying drawing explanation
Fig. 1 is the structural representation of boiling point and the demonstration teaching aid of pressure.
Fig. 2 is the top view of boiling point and the demonstration teaching aid of pressure.
In figure: 1-support bar, 2-base, 3-alcohol burner, 4-fastening bolt, 5-outlet, 6-thermometer, 7-cantilever, 8-container bottle, 9-pressure modulating opening, 10-piston, 11-water inlet.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the technical scheme of this patent is described in more detail.
Refer to the demonstration teaching aid of Fig. 1-2, a kind of boiling point and pressure, including support bar 1, base 2, alcohol burner 3 and container bottle 8；Described base 2 is provided with two support bar 1 and two alcohol burner grooves；Connect between described support bar 1 and have cantilever 7；Two container bottle 8 it are fixed with on described cantilever 7；Described container bottle 8 is provided with water inlet 11, outlet 5, pressure modulating opening 9 and thermometer 6；Described water inlet 11 port is funnel-form, and water inlet 11 cervical region is provided with fastening bolt 4；The cervical region of described outlet 5 is provided with fastening bolt 4, and two outlets 5 link together；Described pressure modulating opening sets 9 piston 10 and fastening bolt 4, and piston 10 is for regulating the pressure size in container bottle 8；The bottom of described fastening bolt 4 is enclosed with soft rubber, and soft rubber can prevent fastening bolt 4 to water inlet 11, outlet 5 and the damage of pressure modulating opening 9 cervical region, can strengthen again sealing, improve the preciseness of experiment.
Operation principle of the present utility model is:
All of fastening bolt 4 is all opened before starting by experiment, injects water, clean container bottle 8 in container bottle 8, shut the fastening bolt 4 at outlet 5, then water filling in container bottle 8 subsequently, when the water yield is suitable, stop water filling and shut the fastening bolt 4 of water inlet 11, now move piston 10, adjust the pressure in bottle, after adjusting, shut the fastening bolt 4 of pressure modulating opening 9, then alcohol burner 3 is lighted, temperature when middle solution seethes with excitement in observing two container bottle 8, thus judge the relation of solution boiling point and pressure.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art is possessed, it is also possible to make a variety of changes on the premise of without departing from this patent objective.
