Abstract
The utility model discloses a tank bottom valve, and particularly relates to a tank bottom valve with a piston rod sealing and positioning mechanism. The tank bottom valve with the piston rod sealing and positioning mechanism is used on a vacuum emulsification agitator. The tank bottom valve with the piston rod sealing and positioning mechanism comprises a valve body, wherein a piston rod which extends downwards is arranged inside the valve body, a plug is arranged on the upper portion of the piston rod, a piston is arranged on the bottom of the piston rod, the bottom end of the valve body and the piston rod are positioned through a shaft sleeve, and the valve body and the piston rod are arranged in a sealed mode through a pair of seal rings which are distributed at intervals. The tank bottom valve with the piston rod sealing and positioning mechanism has the advantages of being simple in structure and excellent in using effect.
