Description
Technical field
The utility model relates to physics teaching experiment instrument field, it is related to a kind of fluid pressure and flow velocity relation demonstrator.
Background technique
For student, fluid pressure is abstract concept, and the relationship of fluid pressure and flow velocity is even more indigestion, mesh
Before, in common fluid pressure and flow velocity relation demonstrator, water storage tank and drainage arrangement are had, Shi Bufang is demonstrated on classroom
Just, not only also water to be discharged for sufficient water, there are also the devices such as air inlet pipe and exhaust pipe, and apparatus structure is complicated, unfavorable
Understand in student, the relation demonstration of fluid pressure and flow velocity is divided into gas pressure intensity and flow velocity relation by the physical teaching aid also having
With liquid pressure and two sets of demonstrators of flow velocity relation, comprehensive difference, teaching efficiency is bad.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of fluid pressure and flow velocity relation demonstrator, and structure is simple, will
Abstract problem embodies visualization, and experimental phenomena is obvious and stablizes, be easy to student to the understanding of fluid pressure and flow velocity relation and
It grasps.
The utility model adopts the following technical solution realizes goal of the invention:
A kind of fluid pressure and flow velocity relation demonstrator, including sink, one bottom end of sink are provided with micro pump, institute
Micro pump connection hose is stated, tongs are set on the hose, the hose connects lateral extra heavy pipe, the transverse direction extra heavy pipe connection
Thin bend pipe, the thin bend pipe mouth are provided with piston, the thin bend pipe mouth for being provided with piston towards sink, the transverse direction extra heavy pipe and
Thin bend pipe top be all connected with diameter it is identical and be less than the diameter of thin bend pipe with graduated elongated straight tube, the transverse direction extra heavy pipe connects
Water pipe is tapped into, the elongated straight tube top end with a scale is separately connected lateral extra heavy pipe and lateral tubule, the transverse direction extra heavy pipe connection
Lateral tubule, the transverse direction extra heavy pipe connect micro-suction pump.
Further define that the micro pump is 15 watts of current stabilization micro pumps as to the technical program.
Further define that the aspiration pump is 110 watts of current stabilization micro-suction pumps as to the technical program.
The lateral extra heavy pipe connection water inlet pipe is further defined that as to the technical program.
Further define that the elongated straight tube is carved with scale as to the technical program.
Compared with existing instrument and technology, the advantages of the utility model and good effect:
Utilize the pressure of fluid and the relationship of flow velocity: the faster position of flow velocity, pressure are smaller；The slower position of flow velocity, pressure
It is bigger；The piston of tongs and thin bend pipe mouth is opened, micro pump is started, allows water to pass through lateral extra heavy pipe and thin bend pipe, passes through sight
Two differences in height for having scale elongated straight intraluminal fluid face are examined, the relationship of liquid pressure and flow velocity is demonstrated, close tongs and use
Piston blocks thin bend pipe mouth, injects a certain amount of water by water inlet pipe, starts aspiration pump, passes through observation elongated straight intraluminal fluid face
Difference in height demonstrates the relationship of gas pressure intensity and flow velocity.
The present invention is suitable for junior physics classroom experiment teaching demonstration, and apparatus structure is simple, easily operated, passes through a set of reality
The relationship of fluid pressure and flow velocity can be demonstrated by testing instrument, vivid, and comprehensive strong, intuitive is strong, be had high visible
Degree, effect are obvious and stablize, and student can be allowed to have a deep understanding and understanding to the relationship of fluid pressure and flow velocity, secondly,
This laboratory apparatus various pieces be all it is removable, allow student voluntarily to assemble laboratory apparatus, the manipulative ability of student can be improved
And elaborative faculty.
Detailed description of the invention: Fig. 1 is the structural schematic diagram of fluid pressure and flow velocity relation demonstrator
