The invention relates to a separated-type oscillatory vacuum insertion board and a valve core; a valve can be closed or opened through an oscillatory method so that a whole length of the valve can be shortened correspondingly to a drift diameter; a valve body comprises a valve body shell; the valve body shell comprises a valve body valve cavity and a valve hole; the valve body shell also comprises a shaft hole and a shaft sleeve on the outer side of the shaft hole; a valve cover can be detachably connected with the valve body in a sealing manner; a transmission shaft perforates the shaft sleeve and the shaft hole on the valve body and is sealed with the shaft sleeve through a shaft sealing component in a free rotation manner; a valve core is located in a valve cavity and comprises a support board, a valve board and a ball body frame; a rotary ball body is arranged on the ball body frame; the ball body frame is arranged between the support board and the valve board; the support board can be movably connected with the valve board correspondingly to an axial direction; the support board and the valve board comprises ball pits correspondingly to the ball body; the ball body frame is connected with an oscillatory rod which is extended outwardly, so that the oscillatory rod can drives the ball body frame to rotate, thereby enabling the ball body to be crawled out of the ball pits; or the oscillatory rod can drives the ball body frame to rotate, thereby enabling the ball body to enter the ball pits.
Description
technical field [0001] The invention relates to a vacuum valve, which is suitable for use in various vacuum systems and is used for cutting off or connecting gas circuits. Background technique [0002] Most of the equipment now uses a rectangular linear motion flapper valve, whose length is three times the diameter. Its size is too large for some new technologies and new equipment, which is uneven and unsightly. Contents of the invention [0003] The object of the present invention is to provide a split-type swing vacuum plug-in valve and valve core, which can close or open the valve by swinging, so that the overall length of the valve can be shortened relative to the diameter. [0004] The split-type swing vacuum plug-in valve for achieving the above-mentioned purpose is characterized in that it includes a valve body, including a valve body shell, the valve body shell has a valve body valve cavity and a valve hole, the valve body shell also has a shaft hole and The shaft...
