Abstract
A fluid motion regularity law demonstrator, comprising a vertical support, a water containing bottle, a water receiving bottle, characterized in that the middle part of the vertical support is fixed with a large tee, the front end of the tee is in screw connection with a small tee, the small tee is connected with the water receiving bottle via a duct, the upper part of the vertical support is disposed with a transverse support, the water containing bottle is disposed on the transverse support, the water containing bottle is connected with the large tee via the duct. The utility model has advantages of simple structure, convenient operation, excellent practicability; the device can provide better demonstration of fluid pressure intensity law to the student to the students than the gas demonstration device so that the students can comprehend and master the taught knowledge. The utility model can demonstrate fluid motion law of larger tube diameter, lower flow rate; smaller tube diameter, high flow rate; and lower flow rate, higher pressure intensity; and higher flow rate, lower pressure intensity during stationary flow.
Description
Technical field
The utility model relates to a kind of teaching aid, particularly relates to a kind of fluid motion rule demonstration device.
Background technology
In the existing teaching, the teacher is when the explanation reflection law, because the instruments used for education that are not easily understood, the student can not observe intuitively, causes student's convection cell pressure rule to lack deep understanding, thereby can not grasp the knowledge of being learned better.
Summary of the invention
The purpose of this utility model is to provide a kind of fluid motion rule demonstration device, so that allow the student more clearly be familiar with the fluid pressure rule.
The technical scheme that adopts is:
A kind of fluid motion rule demonstration device, comprise stand, be filled with water the bottle, the water receiving bottle, it is characterized in that being fixed with a full three links pipe at the middle part of stand, the front end of full three links pipe is bolted with a mini three links pipe, the mini three links pipe links by a conduit and water receiving bottle, one lateral frame is arranged at the top of stand, and the bottle that is filled with water is arranged on the lateral frame, and the bottle that is filled with water links by conduit and full three links pipe.
The utlity model has advantages such as simple in structure, easy to operate, practical, this device can make the student more clearly be familiar with the fluid pressure rule, and is more obvious than gas demonstration device, the student is more readily understood and grasp the institute gain knowledge.
The utility model can be known demonstration in permanent flow, and caliber is big, flow velocity is little, and Guan Lvxiao, flow velocity are big, and flow velocity is little, and pressure is big, and flow velocity is big, the fluid motion rule that pressure is little.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
