( 4 ) triple curling structural design calculations
5 , drums closure

( A ) closed hoop closure
① Screw type closure of hoops. Forming ring with a screw connection with the ends of the means to achieve a fixed lid .
② leveraged closed hoop . Formed by a lever connected to both ends of the ring , carry handle lid fixing apparatus can be achieved .

( 2 ) screw closure
Screw type closure into cocks , capping of two types .

① cock -type closure

② press pressure sealer

( 3 ) Top Press closure : is divided into two kinds of gland bolts type and style .
① bolt top closure pressure

② gland -type closure
