Abstract
The utility model provides a device for demonstrating atmospheric pressure, relating to a teaching instrument for demonstrating atmospheric pressure. The device comprises a sealed container which is internally provided with a first pipe, a second pipe and a third pipe that are communicated to the bottom thereof; a water outlet of the first pipe is arranged at the lower part of the container; a water outlet of the second pipe is arranged on the top part of the container; a water outlet of the third pipe is connected with a rubber air bag; and the three pipes are provided with a valve respectively. The device can conveniently demonstrate the atmospheric pressure phenomenon.
Description
Technical field
The utility model relates to a kind of atmospheric pressure teaching demonstration instrument, specifically a kind of atmospheric pressure apparatus for demonstrating.
Background technology
At educational stages such as middle and primary schools, go up in the physics lesson to the student and will tell about the atmospheric pressure phenomenon, because atmospheric pressure is to cannot see impalpablely, need demonstrate by certain device usually.Common way is to use a water tumbler, covers with glass sheet by the water cup mouth of filling water at one, holds glass sheet by atmospheric pressure and demonstrates atmospheric existence.But in this course, glass sheet comes off easily, and water will be trickled down a ground, and it is very inconvenient to use.
The utility model content
The purpose of this utility model is to provide a kind of atmospheric pressure experimental provision, can demonstrate the atmospheric pressure phenomenon very easily.
The technical scheme in the invention for solving the technical problem is: this kind atmospheric pressure apparatus for demonstrating, it is characterized in that, comprise an airtight container, first pipe, second pipe and three pipe of perforation to the bottom arranged in the described container, the water delivering orifice of first pipe is positioned at the bottom of container, the water delivering orifice of second pipe is at the top of container, and the water delivering orifice of the 3rd pipe connects a rubber pneumatic bag; And on described three pipes valve is arranged all.
The beneficial effects of the utility model are: the atmospheric pressure experimental provision, can demonstrate the atmospheric pressure phenomenon very easily.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1 first pipe, 11 first valves, 2 second pipes, 21 second valves, 3 the 3rd pipes, 31 the 3rd valves, 4 containers.
Embodiment
As shown in Figure 1, this kind atmospheric pressure apparatus for demonstrating comprises an airtight container 4, and first pipe 1, second pipe 2 and three pipe 3 of perforation to the bottom arranged in the described container.
The water delivering orifice of first pipe 1 is positioned at the bottom of container 4, draws from sidewall, and overhanging end is provided with first valve 11; The water delivering orifice of second pipe 2 is drawn from upside at the top of container 4, and overhanging end is provided with second valve 21; The water delivering orifice of the 3rd pipe 3 connects a rubber pneumatic bag 5, and is provided with the 3rd valve 31 between them.
Using method is:
1. fill water in the container, close second valve 21 and the 3rd valve 31, open first valve 21, water can not flow out from first pipe 1; Open second valve 21 and the 3rd valve 31, water can flow out from first pipe 1;
2. close second valve 21, open first valve 11 and the 3rd valve 31, can see that air bag 5 becomes flat, illustrate that atmospheric pressure can oppress deformation of body;
3. close first valve 11 and second valve 21, after the air emptying in the air bag 5, unclamp hand and can find that the water in the container 4 enters air bag 5, illustrate that hyperbar forces water to flow to the low place of air pressure.
Except that the described technical characterictic of instructions, be the known technology of those skilled in the art.
