Description

Technical Field

[0001] The dynamic vacuum hemisphere theory technology belongs to the field of gas flow dynamics. It is a dynamic experiment based on the original Magdeburg hemisphere experiment by improving the two hemispheres, recombining them and evacuating them into a vacuum. Background Art

[0002] The Magdeburg hemisphere experiment revealed the existence of atmospheric pressure, and the Torricelli experiment confirmed the vacuum pressure, and also confirmed that the atmosphere has mass. The way Torricelli's experiment forms a vacuum is the combination of liquid and solid, and the experiment also explains that air can transmit pressure through the combination of liquid and solid. The way the Magdeburg hemisphere experiment forms a vacuum is to use solids to evacuate the vacuum, and the experiment explains that air directly transmits pressure through solids. There are currently two types of vacuums in the material world, one is the combination of liquid and solid, and the other is solid. Both experiments are static experiments, and it is impossible for gaseous substances to show centripetal force and centrifugal force at the same time. If centripetal force and centrifugal force cannot be achieved at the same time, even if the flow direction of gaseous substances cannot be controlled, if liquid and solid are combined to form a vacuum for dynamic experiments, then the liquid will produce fluidity with the dynamic experiment. If you want to understand the overall flow direction of gaseous substances, you need to clean the liquid. Obviously, the method of cleaning the liquid is not feasible, and the only way to do a dynamic experiment is to use the Magdeburg hemisphere experiment. Summary of the invention

[0003] The technology to be solved: Since the Magdeburg hemisphere experiment can only verify the existence of atmospheric pressure, but cannot use the special advantages of the hemisphere plus the dynamic mode of rotation to control the flow direction of the gaseous material pressed on the hemisphere, the present invention discloses the dynamic vacuum hemisphere theory technology to make up for the defects in the Magdeburg hemisphere experiment and reveal that the gaseous material can be controlled under the rotation of the special vacuum hemisphere. Technical solution: (1) First, make a special hemisphere; prepare two different hemispheres, one deep and one shallow, with equal diameters, and the shallow ball overlaps on the deep ball to form a sandwich space. The two balls are sealed and firmly adhered, and vacuum is drawn to form an integral vacuum hemisphere. Two grab rings are welded at the center of the two sides, and both sides are pulled hard to check whether there is pressure. (2) According to the hemisphere design of (1), add a rotating mold, and the special vacuum hemisphere is erected with the ball mouth facing forward. The outer side of the ball is fixed on the rotating mold. Turn on the rotation mode, take a lit candle, and make the candle flame close to the outer and inner sides of the vacuum hemisphere to detect whether the flow direction of the gaseous material pressed on the outside and inside of the vacuum hemisphere has centrifugal force and centripetal force. Note: If the rotating hemisphere is not a vacuum, then the centripetal force and centrifugal force cannot be detected. Only when the hemisphere is a vacuum can the flow direction of the gaseous material change. (3) After determining the centripetal force and centrifugal force, a circular opening is made at the bottom center of the hemisphere, and a hollow circular tube is used to connect the bottom center of the hemisphere and seal it tightly. The opening of the hollow circular tube must be slightly lower than the bottom of the ball or level with the bottom of the ball. It does not matter if the hollow circular tube extends beyond the ball. The ball is evacuated into a vacuum and fixed on a rotating mold. The rotation mode is started. A lit candle is taken and the candle flame is brought close to the two ends of the hollow circular tube. Whether the gaseous substance flows out from the hollow circular tube at the bottom of the hemisphere is detected. This step must ensure that the hemisphere is in a vacuum. Beneficial effect; Compared with the Magdeburg hemisphere experiment, the dynamic vacuum hemisphere experiment of the present invention has the following technical advantages: (1) It has centripetal force and centrifugal force when the vacuum hemisphere rotates. (2) It can change the flow direction of the gaseous substance in the fluid. (3) It can guide the gaseous substance to flow out from the designed hollow circular tube. (4) Once the flow of gaseous substance is mastered, the practicality is that we only need to master the technical principles in the dynamic vacuum hemisphere experiment and combine some application technologies in reality to directly convert energy into energy.

[Example 3] Figure 3 The static atmospheric pressure experiment was improved by using a rotating mold to fix the vacuum hemisphere and start the rotation mode, such as Figure 4 Dynamic diagram of vacuum hemisphere. Take a lit candle and bring the candle flame close to the inner and outer edges of the hemisphere to check the centripetal and centrifugal forces. [Example 4] Figure 4 A circular hole is opened at the bottom center of the vacuum hemisphere, and a hollow circular tube is used to connect the bottom of the hemisphere and seal it tightly. The inner tube opening is level with or slightly lower than the bottom of the ball, and the outer tube opening can extend beyond the ball.
