Siphon device applied to teaching experiment

Abstract

The invention discloses a siphon device applied to a teaching experiment. The siphon device comprises a glass bottle A and a glass bottle B, wherein the glass bottle A and the glass bottle B have the same specification. A cork A and a cork B are respectively plugged into the glass bottle A and the glass bottle B. A connecting pipe A and a connecting pipe B are respectively inserted into the cork A and the cork B. The top parts of the connecting pipe A and the connecting pipe B extend out of the corks and are connected together through a rubber pipe C. The bottom parts of the connecting pipe A and the connecting pipe B extend into the bottle bodies and are respectively connected with a rubber pipe A and a rubber pipe B, wherein the rubber pipe A and the rubber pipe B extend into the bottle bottom. A glass pipe A and a glass pipe B are arranged at the upper part of the glass bottle A. A glass pipe C is arranged at the lower part of the glass bottle A. Glass pipes D, E and F corresponding to the glass pipes A, B and C of the glass bottle A are arranged on the glass bottle B. The glass pipes A, B, C D, E and F are connected with the bottle bodies to form a whole body and are plugged with rubber plugs. According to the invention, the structure is simple; the demonstration experiment of a siphon phenomenon can be quickly completed; the experiment phenomenon is obvious and visual; and the siphon device is mainly applied to the teaching experiment of the siphon phenomenon.

Description

technical field [0001] The invention relates to a siphon device, in particular to a siphon device for teaching experiments. Background technique [0002] The siphon phenomenon is caused by the gravitational force and potential energy difference between liquid molecules, that is, using the pressure difference of the water column to make the water rise and then flow to the lower place. Because the water surface of the nozzle is subjected to different atmospheric pressures, the water will flow from the side with high pressure to the side with low pressure until the atmospheric pressure on both sides is equal, the water surface in the container becomes the same height, and the water will stop flowing. [0003] At present, demonstration experiments of siphon phenomenon are often done in middle school teaching experiments, but the traditional utensils for demonstration experiments of siphon phenomenon are simple two open glass bottles and a rubber tube. This kind of traditional a...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problems that the traditional siphon device for teaching experiments can only suck with the mouth when doing demonstration experiments, can only observe the water flowing into the bottle from the top of the glass bottle, the effect is not intuitive, and the experimental phenomenon and function are relatively single. Provide a siphon device for teaching experiments that can well solve the above problems
