The sealing structure of bottom silo device can be separated into soft and rigidity sealing. Soft sealing is to put wool felt between valve core and valve body. Rigidity sealing is to add connector at the discharging inlet. Steel arc sealing segments are installed between the connector and valve core to realize rigidity sealing with valve core. The sealing clearance can be adjusted to be suitable for frequent action and high temperature conditions. The sealing efficiency is good. The using life is long.
