Abstract
Provided is a liquid flow rate and pressure intensity relationship demonstrator. The liquid flow rate and pressure intensity relationship demonstrator comprises a base and a back plate vertically arranged on the base, wherein the base is provided with a liquid circulation flow system, and the back plate is provided with a pressure intensity display system. The liquid circulation flow system comprises a water storage tank, a small water pump and a connecting pipe. The pressure intensity display system comprises a fat pipe made of transparent materials, a tubule made of transparent materials and three pressure intensity display columns, wherein ends of each pressure intensity display column are open. A water outlet of the water storage tank, the small water pump, the connecting pipe, the fat pipe, the tubule and a water inlet of the water storage tank are communicated sequentially. The fat pipe and the tubule are both arranged horizontally. The pressure intensity display columns are arranged vertically, wherein two pressure intensity display columns are arranged on the fat pipe, and one pressure intensity display column is arranged on the tubule. The liquid flow rate and pressure intensity relationship demonstrator has the advantages of being reasonable in design, simple in structure, strong in appropriability, obvious and stable in effects, strong in practical applicability, and easy to popularize and apply, demonstrating the relationship of the liquid flow rate and the pressure intensity, having strong visibility, and improving teaching effects fully.
Description
Technical field
The utility model relates to a kind of instruments used for education, particularly a kind of flow rate of liquid and pressure relations presenter.
Background technology
In newly organized compulsory education Physics Course standard (in February, 2012 promulgation), propose: " understanding rate of flow of fluid and the relation of pressure and the application in life thereof ".
Probing into rate of flow of fluid and pressure relation is the junior middle school physics teaching content, still, never has since the establishment of the nation instrumentation.This teaching instrumentation is the domestic approved product that there is no at present.
The utility model content
The utility model provides a kind of flow rate of liquid and pressure relations presenter in order to solve weak point of the prior art.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: flow rate of liquid and pressure relations presenter, comprise base and the vertical backboard that is located on the base, base is provided with the mobile system of liquid-circulating, backboard is provided with the pressure display system, the liquid-circulating system that flows comprises water storage box, little water pump and connecting pipe, the pressure display system comprises the extra heavy pipe of being made by transparent material, the pressure display column that tubule and three radicles are uncovered, the water delivering orifice of water storage box, little water pump, connecting pipe, extra heavy pipe, the water inlet of tubule and water storage box is communicated with successively, described extra heavy pipe and tubule all are horizontally disposed with, pressure display column vertically arranges, two pressure display columns are located on the extra heavy pipe, and a pressure display column is located on the tubule.
Adopt technique scheme, in water storage box, be filled with a certain amount of water, open little water pump, the water that little water pump extracts in the water storage box passes through connecting pipe successively, be back to again in the water storage box behind extra heavy pipe and the tubule, since little water pump the velocity-stabilization that draws water, the internal diameter of extra heavy pipe is greater than the internal diameter of tubule, the flow velocity of water nature is less than the flow velocity of water in the tubule in the extra heavy pipe, this process finds that also the water colunm height in the pressure display column that extra heavy pipe connects is higher than the water colunm height in the pressure display column that is connected with tubule, this just illustrates and exists pressure in the flowing liquid, the size of pressure is relevant with flow rate of liquid, and the flow velocity of liquid is larger, and its pressure is just less.The water circulation that little water pump extracts in the water storage box flows, and continuous working can long period observation experiment result.
The utility model is reasonable in design, simple in structure, specificity is strong, and demonstration rate of flow of fluid and pressure relation have extremely strong visibility, and successful and stable has fully improved teaching efficiency, and is practical, is easy to apply.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, flow rate of liquid of the present utility model and pressure relations presenter, comprise base 1 and the vertical backboard 10 that is located on the base 1, base 1 is provided with the mobile system of liquid-circulating, backboard 10 is provided with the pressure display system, the liquid-circulating system that flows comprises water storage box 2, little water pump 3 and connecting pipe 4, the pressure display system comprises the extra heavy pipe 5 of being made by transparent material, the pressure display column 7 that tubule 6 and three radicles are uncovered, the water delivering orifice of water storage box 2, little water pump 3, connecting pipe 4, extra heavy pipe 5, the water inlet of tubule 6 and water storage box 2 is communicated with successively, extra heavy pipe 5 and tubule 6 all are horizontally disposed with, pressure display column 7 vertically arranges, be connected with two pressure display columns 7 on the extra heavy pipe 5, be connected with a pressure display column 7 on the tubule 6.
When demonstrate in the classroom, at first in water storage box 2, be filled with a certain amount of water, open little water pump 3, the water that little water pump 3 extracts in the water storage box 2 passes through connecting pipe 4 successively, be back to again in the water storage box 2 behind extra heavy pipe 5 and the tubule 6, since little water pump 3 the velocity-stabilization that draws water, the internal diameter of extra heavy pipe 5 is greater than the internal diameter of tubule 6, the flow velocity nature of extra heavy pipe 5 interior water is less than the flow velocity of tubule 6 interior water, this process finds that also the pressure display column 7 interior water columns 8 of extra heavy pipe 5 connections highly are higher than water column 9 height in the pressure display column 7 that is connected with tubule 6, this just illustrates and exists pressure in the flowing liquid, the size of pressure is relevant with flow rate of liquid, the flow velocity of liquid is larger, and its pressure is just less.
