• a sealing cover placed on said division plate at the top, to seal said gas outlet hole;
• a pressure cushion placed on said sealing cover at the top, having a pin vertically projecting upwards at the center;
• a gas flow rate regulating device comprising a cylindrical body set in said control chamber, said cylindrical body having nozzle tip disposed at the top and defining therein a gas passage way longitudinally piercing through said cylindrical body, an outer thread portion on the outer wall surface thereof screwed up with said inner thread portion of said control chamber, an annular groove around the outer wall surface thereof at a position below said outer thread portion, and an O-ring mounted on said annular groove to seal the gap between said cylindrical body and said control chamber;
