Abstract
The utility model provides an apparatus for demonstrating the internal pressure of liquid, which relates to an improvement of the structure of the apparatus for demonstrating the internal pressure of liquid. The apparatus for demonstrating the internal pressure of liquid has an evident visual effect. The apparatus comprises two like bottles. The structure of the apparatus has the following characteristics: a conduit with an air injection tube is arranged in a left bottle cork, the lower outlet of a glass tube in the left bottle is in the water in the left bottle, and a communicating conduit is arranged between the left bottle and the right bottle; a glass tube and a bent conduit are arranged in a right bottle cork, and the lower outlets of both the glass tube and the bent conduit in the right bottle are in the water in the right bottle.
Description
Technical field:
The utility model is the improvement of liquid internal pressure apparatus for demonstrating structure.
Background technology:
The demonstration DeGrain of traditional liquid internal pressure apparatus for demonstrating is so can not cause the learning interest of students.
The utility model content:
The utility model is exactly at the problems referred to above, and a kind of outstanding effect liquid internal pressure apparatus for demonstrating directly perceived is provided.
For achieving the above object, the utility model adopts following technical scheme, the utility model comprises two identical bottles, be provided with the conduit of gas injection tube in its structural feature left side bottle stopper, and in the water in the bottom of the glass tube in the bottle of the left side outlet on the left side bottle, in the bottle of the left side and between in the bottle of the right individual connecting tube is arranged; The right is provided with glass tube, curved conductor in the bottle stopper, and the bottom outlet of the glass tube in the bottle of the right, curved conductor is all on the right in the water in the bottle.
The beneficial effects of the utility model:
Apparatus for demonstrating of the present utility model, as long as by gas injection in the bottle, promptly can be observed tangible pressure change situation, experimental phenomena is illustrated in face of the student intuitively, this has not only improved learning interest, is beneficial to this part mastery of knowledge again.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
The utility model comprises two identical bottles 2,10, be provided with the conduit 7 of gas injection tube 8 in the left side bottle stopper 6, and in the water in the bottom of the glass tube 9 in the left side bottle 10 outlet on the left side bottle 10, in the left side bottle 10 and between in the right bottle 2 individual connecting tube 5 is arranged; The right is provided with glass tube 3, curved conductor 1 in the bottle stopper 4, and the bottom outlet of the glass tube 3 in the right bottle 2, curved conductor 1 is all on the right in the water in the bottle 2.
During use,, can find that the liquid level of the curved conductor 1 of the liquid level of glass tube 3,9 in two bottles 2,10 and the right bottle 2 begins to rise at first along conduit 7 gas injection in left side bottle 10, and highly identical.The pressure that is added on the enclosed liquid is described, to all equating that all directions are transmitted.
