Abstract: An apparatus for sealing a vacuum chamber having a plurality of long cylinders for linearly moving first piston rods. The first piston rods connect with a frame elevator. The frame elevator has a second piston rod and guide stems parallel to the first piston rods. A lever, a transmitting rod and a connecting rod are synchronously moved, when the second piston rod is moved parallel to the guide stems by a short stroke cylinder. The transmitting rod is pivoted with a middle of the connecting rod. Direction-changing mechanisms are pivoted at the two ends of the connecting rod for horizontally moving a door to seal the vacuum chamber. The moving direction of the door pushed by the direction-changing mechanisms is perpendicular to the moving direction of the second piston rod so that the apparatus has a thin configuration.

Abstract: An apparatus for sealing a vacuum chamber mainly comprises a plurality of long cylinders for linearly moving first piston rods. The first piston rods connect with a frame elevator. The frame elevator has a second piston rod and guide stems parallel to the first piston rods. While the second piston rod moves parallel to the guide stems by means of the short stroke cylinder, a lever, a transmitting rod and a connecting rod are driven synchronously. The transmitting rod is pivoted with the middle of connecting rod. The direction-changing mechanisms are pivoted at the two ends of the connecting rods for horizontally moving a door to seal the vacuum chamber. The moving direction of the door pushed by direction-changing mechanisms is perpendicular to the moving direction of the second piston rods so that the apparatus has a super thin configuration.

Abstract: A vacuum type distilling system includes a sealed container including a vaporization chamber for containing a liquid and a condensation chamber, a pressure-reducing device, a condensing device, a heating device, and a vapor-collecting device including a floating piston for separating liquid and vapor and a guide tube for guiding vapor generated in the vaporization chamber into the condensation chamber. Liquid to be distilled is filled into the vaporization chamber and the pressure of the sealed container is reduced such that the boiling point of the liquid in the vaporization chamber is lowered. The heating device heats and thus vaporizes the liquid in the vaporization chamber into vapor which is immediately conveyed into the condensation chamber where vapor is condensed into distilled liquid by a condensing tube of the condensing device that is mounted in the condensation chamber.
