The invention relates to the related technical field of manufacturing of vacuum equipment, and discloses an air extractor for a spherical Tokamak device, the air extractor comprises an air suction shell, one side of the air suction shell is fixedly provided with an air delivery pipe, the inner wall of the air suction shell is movably provided with a driving block, and the middle part of the inner wall of the driving block is movably provided with a sealing ring. By arranging the driving block and the driven block, in the process that the driving rod drives any one of the driving block and the driven block to rotate, it is guaranteed that when the driving block and the driven block rotate relatively through the air suction cavity reserved between the driving block and the driven block, air in the air conveying pipe is sucked through opening of the air suction cavity, and meanwhile the air in the air conveying pipe is sucked out through opening of the air suction cavity. In the process that the driving block continuously extrudes and rotates, airflow in the air suction cavity is discharged from the exhaust passage, it is guaranteed that airflow suction is continuously achieved through rotation between the driving block and the driven block, and finally the purpose of efficiently manufacturing a vacuum environment is achieved.
Description
technical field [0001] The invention relates to the related technical field of manufacturing vacuum equipment, in particular to an air extraction device for a spherical tokamak device. Background technique [0002] Vacuum Ultraviolet Spectroscopy (VUV) diagnosis is one of the most important diagnostic techniques in plasma spectroscopic diagnosis on tokamak. Rotational velocity, etc., is a powerful and commonly used diagnostic tool for studying plasma particle transport, confinement quality, and impurity control. However, due to the serious absorption of plasma spectral radiation in the VUV band when it propagates in the atmosphere, the entire optical path from the plasma to the spectral detector must be in a vacuum condition. [0003] However, when the existing vacuum suction devices are in use, most of them are rectangular covers and the connecting valve is installed in the center of the rectangle, so that there is a lot of gas remaining in the periphery during the vacuum ...
