Abstract
This utility model relates to the field of valve technology, specifically to a cylinder for a vacuum chamber valve, comprising a first cylinder and a second cylinder. Both the first and second cylinders have internal telescopic components, which are fixedly connected by a connecting plate. The first and second cylinders are respectively fixedly connected to a first mounting plate. The first cylinder is fixedly connected to a first support frame, and the second cylinder is fixedly connected to a second support frame. The first and second support frames are fixedly connected by a second mounting plate, forming a cylinder circuit. The first and second cylinders are connected to the same external air source, and the stroke of the two cylinders is synchronously controlled through the cylinder circuit, resulting in good stability and synchronization of the connecting plate. The telescopic components can be optionally equipped with telescopic rods and other parts during assembly to improve the ability of the first and second cylinders to withstand lateral loads, thus addressing a wider range of application scenarios.
