チ。In a conical hatch which is configured to seal a conical jet hole bored in a pressure-resistant container by fitting a conical sheet hatch cover, the inner end is concentrically fixed to the outside of the outer surface of the conical hatch cover near its periphery. an annular retainer having an L-shaped cross section whose outer end extends in the lateral direction slightly beyond the outer circumference of the cover; and an annular retainer having an open end of the parallel flange portion each fixed to the lower surface of the retainer and a closed end thereof and the conical sheet. It is characterized by comprising: an annular rubber gasket having a U-shaped cross section that abuts over the outer periphery of the batch cover and the inner periphery of the conical cutter sheet hatch; and a pressure equalizing hole that penetrates the parallel flange portion of the rubber gasket and communicates between the inside and outside of the rubber gasket. Conical hatch.
