Embodiment 1
[0030] see Figure 1-5 , in the embodiment of the present invention, a kind of multi-functional physical gas work experiment equipment comprises box body 4, and experiment panel 5 is arranged in box body 4; Transparent glass bottle 6 and electrical connection are arranged on described experiment panel 5 Touch screen 1, pressure gauge 3, temperature sensor 7, air pump 13, PLC controller 14 and power supply module, wherein the bottleneck place of described transparent glass bottle 6 is equipped with bottle stopper 12, and the bottle body of transparent glass bottle 6 is provided with three Three vents, three vents are respectively connected with pressure gauge 3, temperature sensor 7 and air pump 13 through pipeline, wherein air pump 13 is used for pumping air into transparent glass bottle 6, and temperature sensor 7 is used for monitoring transparent glass bottle 6 The pressure gauge 3 is used to monitor the pressure in the transparent glass bottle 6. During use, the bottle sto...
Embodiment 2
[0045] Embodiments of the present invention provide a method for using the test equipment as described in Embodiment 1, specifically as follows:
[0046] 1) First open the box 4, control the box to the test state (open 90° and fix it) by controlling the hinge 10, close the control switch 9, and then the touch screen 1 and the PLC group are running;
[0047] 2) Spray a small amount of alcohol or clear water into the transparent glass bottle 6, and plug the bottle stopper 12;
[0048] 3) Start the air pump by controlling the touch screen 1. At this time, you will find that the pointer of the pressure gauge 3 starts to move, indicating that the indication is getting higher and higher. The touch screen 1 shows that the temperature is gradually increasing, and the temperature curve begins to generate peaks upwards, and the buzzer alarms The buzzer of the alarm 2 sounds, and the alarm light flashes; after the plug of the transparent glass bottle 6 is pushed out, there is obvious whi...

Abstract
The invention discloses a multifunctional physical gas acting experimental apparatus which comprises a box body. An experimental panel is arranged in the box body; the experiment panel is provided with a transparent glass bottle, a touch screen, a pressure gauge, a temperature sensor, an air pump, a PLC controller and a power supply module, wherein the touch screen, the pressure gauge, the temperature sensor, the air pump, the PLC controller and the power supply module are electrically connected. A bottle plug is arranged at a bottle opening of the transparent glass bottle; three air vents areformed in a bottle body of the transparent glass bottle, the three air vents are respectively connected with the pressure gauge, the temperature sensor and the air pump through pipelines, the air pump is used for pumping air into the transparent glass bottle, the temperature sensor is used for monitoring the temperature in the transparent glass bottle, and the pressure gauge is used for monitoring the pressure in the transparent glass bottle. By arranging the transparent glass bottle, the touch screen, the pressure gauge, the temperature sensor, the air pump, the PLC and the power supply module, the physical relation between pressure and temperature can be effectively displayed, and students can master physical knowledge; meanwhile, the whole control process is convenient and fast.
Description
technical field [0001] The invention relates to the field of teaching facilities, in particular to a multifunctional physical gas work experiment equipment. Background technique [0002] Physics is a subject that studies the most general laws of motion of matter and the basic structure of matter. As the leading discipline of natural science, physics studies the most basic forms and laws of motion of all matter, ranging from the universe to elementary particles, and thus becomes the research basis of other natural science disciplines. [0003] In the process of physics teaching, some auxiliary equipment is often used to strengthen students' understanding of knowledge points. However, most of the existing experimental equipment has a single function, and there are many inconveniences in operation, so it is necessary to improve. Contents of the invention [0004] The object of the present invention is to provide a kind of multifunctional physical gas work experiment equipmen...
