Abstract
The utility model provides a demonstration device of air's working and inner energy decreasing, characterized in that the device comprises a vessel 1, an air pump 2, a thermometer 3 and an air release valve 4, wherein the one end of the vessel 1 is connected with the air pump 2, the other end of the vessel 1 is provided with the air release valve 4, a sensing device 31 of the thermometer 3 is arranged in the vessel 1, a the display 32 of the thermometer 3 is at out of the vessel 1. The utility model has the advantages that the operation is safe and simple and the demonstration is reliable and appreciable.
Description
Technical field
The utility model relates to instruments used for education.
Background technology
Can reduce apparatus for demonstrating in the existing gas acting, to inflate constantly for the heavy sheet glass bottle (interior dress little water) that has stopper, gases at high pressure are washed stopper open until the inside, and the mode of wanting to produce simultaneously in the bottle " fog " demonstrate in the gas acting can minimizing, be to demonstrate existing of to reduce in the gas acting in igniting blast mode, operate that dangerous (as the stopper of washing open is easily hurted sb.'s feelings, bottle is thick inadequately, easily explosion), demonstrate unreliable, not obvious (amount of liquid influence generation " fog " effect in the bottle, and " fog " is shorter when depositing, and also is difficult for observing).
Summary of the invention
The purpose of this utility model is to provide in a kind of safe, reliable, tangible gas acting and can reduces apparatus for demonstrating.
The utility model provides in a kind of gas acting can reduce apparatus for demonstrating, it is characterized in that: form by container 1, air pump 2, thermometer 3, air release 4, container 1 one ends are connected with air pump 2, the other end is equipped with air release 4, the sensor 31 of thermometer 3 places 1 li in container, and the display 32 of thermometer 3 places outside the container 1.
When giving container 1 inflation by air pump 2, the pressure of 1 li gas of container strengthens and temperature raises, and it is big that thermometer 3 numerical value become; When opening air release 4, the pressure of 1 li gas of container reduces to reduce with temperature, and thermometer 3 numerical value diminish.
Can reduce apparatus for demonstrating in the gas acting that the utility model provides, its air release 4 places are provided with windmill 5; During air release 4 venting, air-flow promotes windmill 5 rotations, can reduce in the acting of demonstration gas and become the power work done.
Can reduce apparatus for demonstrating in the gas acting that the utility model provides, its advantage is: handling safety, simple, demonstration is reliable, obvious.
Description of drawings
Fig. 1 is for reducing the structural representation of apparatus for demonstrating in the gas acting.
Embodiment
Embodiment 1
Can reduce the apparatus for demonstrating (see figure 1) in the gas acting is made up of container 1, air pump 2 (sphygmomanometer balloon), thermometer 3, air release 4, container 1 one ends are connected with air pump 2, the other end is equipped with air release 4, the sensor 31 of thermometer 3 places 1 li in container, the LCD 32 of thermometer 3 places outside the container 1, and air release 4 places are provided with windmill 5.
During demonstration, when giving container 1 inflation with air pump 2, the pressure of 1 li gas of container strengthens and temperature raises, and thermometer 3 becomes big; When opening air release 4, air-flow promotes windmill 5 rotations, can reduce in the acting of demonstration gas and become the power work done, and the pressure of 1 li gas of container reduces to reduce with temperature, and thermometer 3 LCD 32 registrations diminish.
