Secondary sealing of the sealing flap of the floating roof of the tank

摘要

The utility model relates to the field of reservoir construction, in particular to the sealing gates of floating roofs of tanks, and can be used in the construction of steel cylindrical tanks with floating roofs. In the secondary seal of the sealing flap of the floating roof of the tank, comprising a seal with two horizontal rows of holes for fastening it to the top of the sliding sheet pressed against the wall of the tank by the springs, the seal has a trapezoidal shape with a recess from the side of the tank wall. The technical result is an increase in the gas tightness of the sealing closure and prevention of the accumulation of water in the place of contact of the secondary seal with the wall of the reservoir.
