| titleOfInvention | A kind of plug-type throttling expansion science and technology teaching aid toy |
| abstract | The utility model relates to a kind of plug-type throttling expansion science and technology teaching aid toys, including inflator, water tank A, water tank B, cooling tube and heat outting pipe, bidirectional piston is equipped in inflator, inflator is divided into left air cavity and right air cavity by bidirectional piston, transtracheal A is connected between left air cavity and the lower part of right air cavity, and transtracheal B is connected between left air cavity and the top of right air cavity；Heat outting pipe and cooling tube are respectively provided in water tank A and water tank B, and caliber of the caliber less than tracheae A and transtracheal C of heat outting pipe are connected to tracheae A, and tracheae A is connected with outgassing nonreturn valve in the two sides of tracheae C respectively；The caliber of cooling tube is greater than the caliber of heat outting pipe, and cooling tube is connected to the delivery outlet of heat outting pipe, and the delivery outlet transtracheal D of cooling tube is connected to tracheae B, and tracheae B is connected with breather check valve in the two sides of tracheae D respectively.The structure design of the utility model is reasonable, and the knowledge such as throttling expansion and relevant working principle are intuitively understood convenient for student, has scientific and interest abundant. |
