Abstract
A pressure and water boiling point demonstrator relates to an improvement of the pressure and water boiling point demonstrator. The utility model provides a pressure and water boiling point demonstrator, which can avoid rusting of the pump cylinder. The utility model includes a bracket, a heating flask provided with a heat catheter on the top arranged on the bracket, and an alcohol lamp below the heating flask. The utility model is characterized in that the bracket is provided with a cooling flask, and the heat catheter is arranged on the bottom of the cooling flask through the rubber stopper of the cooling flask; one end of the cooling catheter of the cooling flask is arranged on the upper part of the cooling flask and the other is connected with the exhaust valve.
Description
Technical field:
The utility model relates to the improvement of pressure and water boiling point apparatus for demonstrating.
Background technology:
Traditional pressure and water boiling point apparatus for demonstrating normally are made up of the flask that has gas outlet on the support, spirit lamp; Its shortcoming is when demonstration, does not have the cooling system of steam; When bleeding with pump bowl, will be drawn onto a large amount of water vapor in the pump bowl, in pump bowl, become water, pump bowl is got rusty.
The utility model content:
The utility model is exactly at the problems referred to above, and a kind of pressure and water boiling point apparatus for demonstrating of avoiding pump bowl to get rusty is provided.
The utility model adopts following technical scheme: the utility model comprises support, support is provided with the heating flask that the top has hot gas conduit, the below of heating flask is a spirit lamp, its structural feature support is provided with the cooling flask, and hot gas conduit places the bottom of cooling flask by the rubber stopper of cooling flask; One end of the air coolant tube on the cooling flask is arranged on the top of cooling flask, and the other end of air coolant tube links to each other with vent valve.
The beneficial effects of the utility model:
The utility model pump bowl directly is connected with the cooling flask, and water vapor is in cooling will be trapped in the cooling flask behind the flask in experimentation, and water vapor can not enter into pump bowl, has avoided the pump bowl damage of getting rusty.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
The utility model comprises support 8, support 8 is provided with the heating flask 6 that the top has hot gas conduit 5, the below of heating flask 6 is a spirit lamp 7, and support 8 is provided with cooling flask 3, and hot gas conduit 5 places the bottom of cooling flask 3 by the rubber stopper 4 of cooling flask 3; One end of the air coolant tube 2 on the cooling flask 3 is arranged on the top of cooling flask 3, and the other end of air coolant tube 2 links to each other with vent valve 1.
During use, pump bowl links to each other with air coolant tube 2 by vent valve 1.
