Description
Technical field
This utility model belongs to the teaching aid technical field for law of connected vessels analysis, and in particular to a kind of to be used for linker
The teaching aid of principle analysis.
Background technology
The container that several bottoms interconnect, injects same liquid, each container in linker when liquid does not flow
Liquid level is always remained in same level.The principle of linker can be explained with liquid pressure.If being equipped with U-shaped glass tubing
Same liquid, is envisioned with a little liquid piece AB in the bottom center of linker.If liquid is static immobilising.Zuo Guanzhong
Pressure of the liquid to liquid piece AB to the right, the necessarily pressure equal to the liquid in right pipe to liquid piece AB to the left.Because connection
What device was built-in is same liquid, and the density of two fluid columns in left and right is identical, only when both sides fluid column it is highly equal when, both sides liquid
Post could be equal to the pressure of liquid piece AB.So, in the case of liquid is immobilising, the liquid level in each container of linker should keep
It is equal.Law of connected vessels has a wide range of applications in engineering.Such as various liquid level meter（Water-level gauge, oil level indicator etc.）, hydrargyrum vacuum
Meter, fluid column formula draft gauge, differential pressure gauge, detection means of gas leakage etc., are all using made by law of connected vessels.Current middle school
During explanation in physics teaching with regard to linker part is limited only to the picture provided on textbook and life, some are common
Article is illustrated, and does not have understanding intuitively, or the existing teaching aid for law of connected vessels analysis for student
Student can not be made intuitively accurately to understand the principle of linker, therefore we need a new to analyze for law of connected vessels
Teaching aid, meet the demand of people.
