Sealing ring installation position is provided on face.
Preferably, the carbon steel nut close on vacuum flange disk one end and be dried in vacuo chamber interior wall contact surface between away from
From for be dried in vacuo chamber interior wall wall thickness.
The second object of the present invention is to provide a kind of vacuum drying chamber.
Technical solution is：A kind of vacuum drying chamber, including vacuum drying chamber interior wall and vacuum drying chamber heater, it is described true
Empty drying box heater is above-mentioned vacuum drying chamber heater, and sealing ring is equipped on the sealing ring installation position.
Preferably, the sealing ring is rubber seal.
Preferably, the vacuum flange disk and heater tubulation unit circumference full weld.
The third object of the present invention is to provide a kind of method of anti-vacuum drying chamber vacuum discharge.
Technical solution is：A kind of method of anti-vacuum drying chamber vacuum discharge, this method use above-mentioned vacuum drying chamber,
The vacuum drying chamber is by heating tube directly through vacuum drying chamber interior wall, and heating tube is in case external connection.
Compared with prior art, the beneficial effects of the present invention are：
Heater tubulation unit connection end is designed to vacuum flange disk-form by the present invention.It is set on heater tubulation unit
Vacuum flange disk is counted by heater tubulation unit directly through vacuum drying chamber interior wall, heater tubulation unit and vacuum drying chamber
Inner wall is sealed by rubber seal with nut check, greatly improves the sealing effect of whole equipment in this way.Due to heating
Pipe is at normal atmospheric pressure, to avoid vacuum discharge phenomenon in this way, be highly suitable for vacuum heating apparatus in case external connection
It uses, is sealed by vacuum flange disk and cabinet wall, sealing means and sealing effect are better than the mode of traditional wired terminal.
