Abstract

The invention belongs to the field of vacuum system elements, and particularly relates to a guide rail vacuum connection rod gate valve. The guide rail vacuum connection rod gate valve comprises a valve body (2) of which a work cavity is internally provided with a transmission mechanism; the transmission mechanism comprises two symmetrical parallel guide rails (6); the guide rails (6) comprise an upper layer rail work surface (601) and a lower layer rail work surface (602) of which one end part is provided with a sunk slot (12); the upper layer rail work surface (601) is provided with a valve frame (7) and is in slide connection with a guide wheel mechanism I (4); the lower layer rail work surface (602) is provided with a valve holder (8); a guide wheel mechanism II (5) is in slide connection with the lower layer rail (602); a connection rod (11) is arranged between the valve frame (7) and the valve plate (8). The guide rail vacuum connection rod gate valve is simple in structure, easy to disassemble, good in sealing property, high in reliability and suitable for high-temperature radiation work conditions.

Description

Technical field [0001] The invention belongs to the field of vacuum system components, and particularly relates to a guide rail type vacuum connecting rod plug-in valve applied to vacuum metallurgical equipment with high-temperature radiation to isolate or communicate two chambers. Background technique [0002] In the working process of the vacuum induction furnace, due to the needs of secondary feeding and launder casting, vacuum isolation and sealing are often used between the melting chamber and the feeding chamber and the ingot chamber to realize various operations under vacuum. At present, the valves used are all ball-type vacuum flapper valves or spring-type vacuum flapper valves. The ball type vacuum flapper valve uses an inclined surface to push the ball and tighten the leaf spring to achieve the sealing purpose. However, in the use of the equipment, dust particles often jam the ball, which makes the valve unable to close normally, which greatly reduces the reliability of...
