Abstract
The utility model relates to a teaching apparatus, in particular to an apparatus for teaching and demonstrating the principle of a water pump. The apparatus for teaching and demonstrating the principle of a water pump is simple and has a good visual effect. The apparatus comprises a piston cylinder. The structure of the apparatus has the following characteristics: a piston rod is arranged in the piston cylinder; one end of a tee under the piston cylinder is connected with a water inlet tube with a one-way valve, and the other end of the tee is connected with a water outlet tube with a one-way valve.
Description
Technical field:
The utility model relates to a kind of teaching aid, more particularly, relates to a kind of teaching demonstration device of suction pump principle.
Background technology:
In the physics of middle school, a specific embodiment in the atmospheric pressure content of courses promptly is a suction pump.Suction pump is exactly the variation that has utilized atmospheric pressure, and water is drawn up from lower, is transported to eminence again.Because suction pump is a main equipment, can't move on the classroom and demonstrate, so, only depend on courseware to understand the content of suction pump principle and atmospheric pressure, and be not easy, be difficult to the teaching efficiency that reaches good.
The utility model content:
The utility model is exactly at the problems referred to above, and a kind of teaching demonstration device of easy, suction pump principle that intuitive is strong is provided.
For realizing above-mentioned purpose of the present utility model, the utility model adopts following technical scheme, and the utility model comprises piston cylinder, and its structural feature is to be provided with piston rod in piston cylinder; One end of the threeway of piston cylinder below is connected with the water inlet pipe with retaining valve, and the other end of threeway is connected with the rising pipe with retaining valve.
The beneficial effects of the utility model:
Because teaching demonstration device of the present utility model is provided with piston rod in piston cylinder; One end of the threeway of piston cylinder below is connected with the water inlet pipe with retaining valve, and the other end of threeway is connected with the rising pipe with retaining valve; So it is simple in structure; Simultaneously, make the student can directly witness the course of work of suction pump, intuitive is strong, is convenient to the student content of courses is produced perceptual knowledge, has good teaching efficiency.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
The utility model comprises piston cylinder 4, is provided with piston rod 5 in piston cylinder 4; One end of the threeway 3 of piston cylinder 4 belows is connected with the water inlet pipe 1 with retaining valve 2, and the other end of threeway 3 is connected with the rising pipe 7 with retaining valve 6.
A presentation process below in conjunction with description of drawings the utility model teaching demonstration device:
During demonstration, at first, water inlet pipe 1 is placed in the container that fills water; Lift piston rod 5, the gas pressure intensity in the piston cylinder 4 reduces, and the water in the container flows in the piston cylinder 4 via water inlet pipe 1, threeway 3; Then, promote piston rod 5, because water inlet pipe 1 is provided with retaining valve 2, so the water of piston cylinder 4 flows to rising pipe 7 through threeway 3.Promptly finish presentation process one time.
