Means, vacuum system and related method for making a glass vacuum extraction

The present invention discloses a vacuum extraction apparatus for making vacuum glass, vacuum glass production system and related methods. The vacuum extraction apparatus comprising: a pumping operation of a circular tubular member; cylindrical suction port closing operation member; and a control section; and a drive means. A pumping member and a suction opening closure operating member have the same center axis, an outer member and a pumping and suction port closing operation member is formed in the interior cylinder, two relatively movable along the central axis. Formed in the tube wall has a pumping member pumping channels, and closes the inner tip of the operation member is provided with a heating member in the exhaust ports. The control section relative movement along the central axis by the driving timing control means and a pumping means pumping port closing operation member, the control channel performs pre-evacuation pump / vacuum preloading operation or operation, and for controlling the heating means for heating the sealing plate pumping port closing operation is performed.
