Description
Technical field
The invention belongs to instruments used for education field, more particularly to a kind of gas pressure intensity teaching demonstration instrument.
Background technology
Gas and liquid have common property：Liquid internal one way or another has pressure, in same depth, all directions
(top to bottom, left and right, front and rear) pressure is equal.Liquid internal one way or another has pressure to be due to that liquid can flow.To prove
This physical phenomenon, there is special validation instrument-liquid pressure demonstration instrument, Pascal's ball.Air is also flowing, there is also
The pressure of one way or another, but we can only be tested with plastic suckers, suction pipe sucking material is tested, hot bucket is sealed for cold experiment at present
It is bright.These experiments can illustrate the presence of atmospheric pressure, but can not both qualitative and quantitative ground prove gas towards each side simultaneously
To there is pressure.
The content of the invention
In order to overcome above-mentioned deficiency, it is both qualitative and quantitatively same that the present invention intends a kind of easy to use, simple to operate, energy of offer
When prove that gas one way or another has the gas pressure intensity teaching demonstration instrument of pressure.
A kind of gas pressure intensity teaching demonstration instrument of the present invention：Including syringe, pressure vessel, U-tube, main valve, bearing
And connecting tube, the U-tube bottom is fixed on bearing, and top is connected by connecting tube with pressure vessel, and the syringe passes through
Connecting tube is connected with pressure vessel, and the main valve is arranged on pressure vessel.
Further, the pressure vessel is lucite material, and surrounding is provided with several holes, each hole and is connected with glass
Glass tubule.
Further, the bearing is to be fixed with some aluminium-plastic panels on the iron seat of groove type, iron seat, for placing U-tube,
And with the support of a support pressure vessel.
Further, the two ends of the connecting tube are all fixed with plastics spring, prevent connecting tube from knotting.
The advantage of the invention is that：There is provided a kind of both qualitative and quantitative ground of easy to use, simple to operate, energy proves gas simultaneously
Body one way or another has the gas pressure intensity teaching demonstration instrument of pressure.
Brief description of the drawings
Fig. 1 is a kind of gas pressure intensity teaching demonstration instrument schematic diagram.
Wherein：1 it is syringe, 2 be pressure vessel, 3 be U-tube, 4 be main valve, 5 be bearing, 6 is connecting tube.
Embodiment
Below in conjunction with Figure of description and specific preferred embodiment, the invention will be further described, but not therefore and
Limit the scope of the invention.
As shown in figure 1, a kind of gas pressure intensity teaching demonstration instrument：Including syringe 1, pressure vessel 2, U-tube 3, main valve 4,
Bearing 5 and connecting tube 6, the bottom of U-tube 3 are fixed on bearing 5, and top is connected by connecting tube 6 with pressure vessel 2, institute
State syringe 1 to be connected with pressure vessel 2 by connecting tube 6, the main valve 4 is arranged on pressure vessel 2；The pressure vessel 2 is
Lucite material, surrounding is provided with several holes, each hole and is connected with glass tubule；The bearing 5 is the iron seat of groove type,
Some aluminium-plastic panels are fixed with iron seat, for placing U-tube 3, and with the support of a support pressure vessel 2；The connecting tube 6
Two ends are all fixed with plastics spring, prevent connecting tube from knotting.
This laboratory operating procedures is as follows：(1) dyeing liquor is injected separately into 3~13 U-tubes before testing, arrival refers to
Determine scale, then connect pressure vessel and U-tube with connecting tube, finally connecting tube being connected with syringe, (different azimuth connects
Head can)；(2) when testing, the main valve of pressure vessel is opened, makes the connected one end of container, connecting tube and U-tube and extraneous gas
Pressure is communicated, and the liquid level of all U-tubes is all on identical graduation line, and liquid level is equal；(3) main valve of gas pressure intensity demonstrator is closed,
A certain amount of gas is just enclosed in pressure vessel, the closed gas in the piston of syringe, compression pressure container is promoted, is compressed
Gas transmitted by connecting tube one way or another.It can be seen that every U-shaped being connected with top to bottom, left and right, front and rear institute distribution hole
All there is difference in height in the fluid column that pipe is raised and lowered, illustrates that gas interior one way or another has pressure；It has also been found that pressure gage
The difference in height on both sides is equal, and then it is equal in magnitude to demonstrate the pressure of gas interior one way or another.
The advantage of the invention is that：There is provided a kind of both qualitative and quantitative ground of easy to use, simple to operate, energy proves gas simultaneously
Body one way or another has the gas pressure intensity teaching demonstration instrument of pressure.
Described above is only the preferred embodiment of the present invention, and protection scope of the present invention is not limited merely to above-mentioned implementation
Example.All technical schemes belonged under thinking of the present invention belong to protection scope of the present invention.It is noted that for the art
Those of ordinary skill for, improvements and modifications under the premise without departing from the principles of the invention, these improvements and modifications also should
It is considered as protection scope of the present invention.
