Abstract

PURPOSE: To reduce the temperature and the radiation quantity on the top of the fixed plug and the rotary plug by shutting thereof off the cover gas atmosphere with an insulating plate laminated at the bottom thereof while the circumference thereof is covered with a sheet plate.
CONSTITUTION: A laminated plate 6 is suspended from a fixed plug 4 and a rotary plug 5 with a member 11 and a bolt 12, while the circumference there is wrapped with a sheet plate. The laminated plate 6 is constructed with a gas layer so thick that the convection thereof is hard to occur. Thus, heat conduction by convection is checked. The sheet plate 10 checks the advance of the radiative mist of coolant into the laminated plate thereby reducing the radiation quantity on the top of the plugs.
