Physical atmospheric pressure experiment teaching device

Abstract

The invention discloses a physical atmospheric pressure experiment teaching device, which comprises a device body, a first piston is arranged inside the device body, an exhaust pipe and an air intake pipe are respectively arranged on both sides of the lower part of the device body, and the A check valve is installed on the outside of the exhaust pipe and the intake pipe, and a display box is connected to the side of the device body through a strut. A cylinder is installed at the bottom of the display box, and a second Piston, the inside of the display box is provided with a spring tensioner. In the present invention, an exhaust pipe and an air intake pipe are connected to the lower part of the device body, and a one-way valve is installed. When the first piston moves repeatedly, the air in the air intake pipe and the cylinder body can be gradually discharged. , the second piston descends and then stretches the spring tensioner, the tension display can be seen intuitively through the observation window, the structure is simple, the operation is convenient, the display image is intuitive, and the use is safe and convenient.

Description

technical field [0001] The invention belongs to the technical field of physical experiments, and in particular relates to a teaching device for physical atmospheric pressure experiments. Background technique [0002] Atmospheric pressure is an extremely important concept or natural phenomenon when middle school students study physics. However, the most important thing in learning physics is to be able to feel natural phenomena and laws. This feeling must be obtained through experiments that are closest to nature. The existing atmospheric pressure Strong experiments generally need to be realized through liquid. Although this type of experiment can be demonstrated, the process is cumbersome and requires high operation, which affects the teaching efficiency and quality. To this end, we propose a physical atmospheric pressure experiment teaching device to solve the problems mentioned in the above-mentioned background technology. Contents of the invention [0003] The purpose ...
