Abstract
The utility model relates to a teaching tool used for middle school physics teaching and specifically relates to a siphonage demonstration instrument. The siphonage demonstration instrument includes a container. The siphonage demonstration instrument is characterized in that the upper end of the container is provided with a bottom cap; an air tube and a siphon are inserted in the bottle cap; the air tube is a straight tube and an inner end of the air tube is disposed in an inner cavity of the container; an outer end of the air tube is provided with a tube cap; the siphon is a U-shaped tube and an inner end of the siphon is disposed in the inner cavity of the container; an outer end of the siphon is disposed outside the container; and a bending part of the siphon is provided with a T-branch pipe provided with sealing caps. The siphonage demonstration instrument provided by the utility model is simple in structure and convenient to operate, and can demonstrate siphonage directly. And the demonstration result is quite standard.
Description
Technical field
The utility model relates to a kind of Middle School Physics teaching apparatus, specifically a kind of siphonage demonstration instrument.
Background technology
Siphonage relates to atmospheric pressure and hydraulic pressure, if there is not the demonstrator demonstration, the student is difficult to understand.Owing to there is not the demonstrator of standard, in order to demonstrate siphonage, to prepare the various stage properties such as basin, water pipe on the classroom, need many people's operations.The demonstration operation is pretty troublesome, and the result of demonstration is also very lack of standardization.
Summary of the invention
The purpose of this utility model provides the siphonage demonstration instrument of a kind of simple in structure, convenient operation, demonstration visual result standard.
The utility model is that the technical scheme that the technical solution problem adopts is:
Siphonage demonstration instrument described in the utility model comprises container, it is characterized in that: the upper end of described container is provided with bottle cap, be fitted with respiratory siphon and U trap on the described bottle cap, described respiratory siphon is straight tube, and the inner of respiratory siphon is arranged in the inner chamber of container, the outer end of respiratory siphon is provided with pipe cap, described U trap is the U-shaped pipe, and siphonal the inner is arranged in the inner chamber of container, and siphonal outer end is positioned at the outside of container, siphonal bending place is provided with three-way pipe, on the three-way pipe with sealing cap.
After adopting technique scheme, simple in structure, the convenient operation of this siphonage demonstration instrument can be demonstrated siphonage very intuitively, and demonstrates very standard of result.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model.
Embodiment
As shown in Figure 1, siphonage demonstration instrument described in the utility model comprises container 1, and container can adopt the bottle of the transparent materials such as vial or plastic bottle, is convenient to observe the variation of liquid in the bottle.The upper end of described container 1 is provided with bottle cap 2, is fitted with respiratory siphon 3 and U trap 4 on the described bottle cap 2, and described respiratory siphon 3 is straight tube, and the inner of respiratory siphon 3 is arranged in the inner chamber of container 1, and the inner of respiratory siphon 3 gets final product a little less than bottle cap 2.The outer end of respiratory siphon 3 is provided with pipe cap 5, is used for sealing orifice.Described U trap 4 is the U-shaped pipe, and the inner of U trap 4 is arranged in the inner chamber of container 1, and the inner of U trap 4 extends to the bottom of container 1, and the outer end of U trap 4 is positioned at the outside of container 1, and the outer end opening place of U trap 4 will be lower than the bottom of container 1.The bending place of U trap 4 is provided with three-way pipe 6, with sealing cap 7, is used for sealing orifice on the three-way pipe 6.
During use, filled with water in container 1, the inner that the water surface is higher than the inner of U trap 4 and is lower than respiratory siphon 3 gets final product.Take off pipe cap 5, cover sealing cap 7, this moment can the 1 interior air blowing from respiratory siphon 3 to container, perhaps bleeds from the outer end opening of U trap 4, makes in the U trap 4 to be full of water.After the demonstration beginning, the water in the container 1 constantly flows out by U trap 4, illustrate that hydraulic pressure in the U trap 4 greater than the atmospheric pressure in the container 1, releases water the generation siphonage; At this moment, if pipe cap 5 is covered, the outer end of sealing respiratory siphon 3, although the outer end of U trap 4 is still open, water flowing out, does not illustrate in container 1 to have produced negative pressure that atmospheric pressure and hydraulic pressure are cancelled out each other, and make the water in the U trap 4 stop to flow; Open pipe cap 5 again, open simultaneously on the three-way pipe 6 with sealing cap 7, this moment, air entered U trap 4, had destroyed the condition that siphonage produces, and the water in the container 1 is not flowing out.
