Accompanying drawing explanation
Fig. 1 is the sectional view of the water inlet/outlet device of a kind of high temperature experiment still of the present invention；
Fig. 2 is kettle cover and the sectional view of kettle connection of the water inlet/outlet device of a kind of high temperature experiment still of the present invention.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is expanded on further.It should be understood that these embodiments are merely to illustrate this
Bright, rather than limit protection scope of the present invention.Those skilled in the art are according to changing that the present invention makes in actual applications
Enter and adjust, still falling within protection scope of the present invention.
In order to better illustrate the present invention, below with accompanying drawing, the present invention is described in detail.
As shown in Fig. 1～2, the water inlet/outlet device of a kind of high temperature experiment still of the present invention, including kettle cover 1, kettle 2, tubule 3
With extra heavy pipe 4, the lower end of described kettle cover 1 is communicated with the passage 6 of described kettle 2, and the external diameter of described tubule 3 is less than described
The internal diameter of passage 6, described tubule 3 passage 6 described in edge below described kettle cover 1 lower end extends described kettle 2
Top, i.e. described tubule 3 has one end to be exposed at the external world, as the entrance of cold test medium, it is simple to be passed through room temperature to kettle 2
Test(ing) medium (water), is arranged with outside the tubule 3 described between the lower end of the lower end of described passage 6 and described tubule 3
Described extra heavy pipe 4, the internal diameter of described extra heavy pipe 4 is close with the size of the internal diameter of described passage 6, and described tubule 3 is with described
Passage 6, gap between extra heavy pipe 4 is as the exit passageway of hot test medium.
The present invention is by setting a collar joint 5 on described passage 6, for by described extra heavy pipe 4 with passage 6 even
Logical, described collar joint 5 is threadedly connected on the lower end of the described kettle cover 1 at described passage 6, and leads to described
Road 6 fully seals connection；Described extra heavy pipe 4 and described collar joint 5 are connected through nut 7 is fixing, and with collar joint 5
Fully seal connection.
A length of the 5～6m of described tubule 3；A length of the 5～6m of described extra heavy pipe 4；Described passage 6 and extra heavy pipe 4
Internal diameter be 6.5～7.5mm；The external diameter of described tubule 3 is 3～3.2mm.
The present invention by arranging passage 6 in the lower end of kettle cover 1, and be provided with extra heavy pipe 4 at passage 6 and overlap the device of tubule 3, and
Realize fully sealing connection through collar joint 5 so that the import and export of high temperature experiment still are all in same a bite, and keep sample in still
The temperature of test(ing) medium will not produce the biggest fluctuation.Specifically, the working method of water inlet/outlet device of the present invention is: room temperature tries
Testing medium to flow in high temperature experiment still at the A of tubule 3, flow in the kettle 2 of high temperature experiment still at B, cold test is situated between
Matter is heated obtains high temperature test medium, and when kettle 2 is full of hot test medium, hot test medium flows at the C of passage 6
Going out, then the gap between tubule 3 and passage 6, extra heavy pipe 4 flows to water chemistry closed circuit system.Therefore, cold test medium
During flowing in kettle 2 through tubule 3, cold test medium respectively with the hot test medium flowed out, high temperature in still
Test(ing) medium generation heat exchange, it is achieved the intensification of cold test medium, so that the temperature of the test(ing) medium flowed at B in still
Degree is approximately equal to the temperature of hot test medium in still；Additionally, the test(ing) medium temperature in still is due to thermal convection current phenomenon, top
Temperature is higher than the temperature of bottom, and thus, the test(ing) medium that the temperature of inflow is slightly lower at B just plays neutralization
Effect, in making whole high temperature experiment still, the temperature difference is minimized, it is to avoid the fluctuation of test(ing) medium temperature in still, it is ensured that sample
The uniformity of the test(ing) medium temperature around 8.
Present invention disclosed above preferred embodiment is only intended to help to illustrate the present invention.Preferred embodiment is the most detailed
Describe all of details, be also not intended to the detailed description of the invention that this invention is only described.Obviously, according to the content of this specification,
Can make many modifications and variations.These embodiments are chosen and specifically described to this specification, is to preferably explain the present invention
