Abstract
The utility model discloses a device of demonstration liquid pressure size. This device is measured tin including cylindric flourishing water receptacle and one pressure that concentric and diameter is less than cylindric flourishing water receptacle with cylindric flourishing water receptacle be equipped with two double -phase right through -holes of three -layer on the section of thick bamboo wall of a pressure measurement section of thick bamboo, the rubber membrane to the through -hole upper seal. Owing to adopt above -mentioned structure, can come out simple structure, convenient operation to abstract theoretical image, audio -visual demonstration.
Description
Technical field
The utility model relates to a kind of apparatus for demonstrating of physical phenomenon, particularly relates to a kind of device demonstrating liquid pressure size.
Background technology
At current classroom teaching, because liquid pressure is abstract concept, particularly pressure changes with the change in depth of water, and teacher only relies on explanation, for firm contact liq pressure student not easily understand.Thus bring difficulty to teaching.
Summary of the invention
The purpose of this utility model is to provide the device of a kind of image, directly perceived, lively demonstration liquid pressure size.
The utility model is achieved through the following technical solutions: this device comprises a cylindric water container and one, and concentric and diameter is less than the pressure measurement cylinder of cylindric water container with cylindric water container, the barrel of described pressure measurement cylinder is provided with three layers of through hole facing each other, described through hole encapsulates rubber membrane.
The diameter of described through hole 20 millimeters.
Described rubber membrane has elasticity.
During as experiment, water container is injected more than half clear water, the pressure measurement cylinder that through hole encapsulates rubber membrane is put into water container, at this moment clearly can see that rubber membrane can be protruding to anhydrous side, its degree of convexity increases with the increase of the degree of depth.The rubber membrane degree of convexity of the same degree of depth is identical, illustrates that the pressure of same degree of depth water is identical thus.
The beneficial effects of the utility model: owing to adopting said structure, can abstract theory image, demonstrate out intuitively, and structure is simple, easy to operate.
Accompanying drawing explanation
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing
Fig. 1 is cut-open view of the present utility model
