2014
The invention belongs to the field of ocean devices and particularly relates to a detachable ball sealer. The detachable ball sealer comprises a detachable upper hemisphere and a detachable lower hemisphere. The upper hemisphere and the lower hemisphere are connected in a sealed mode through a sealing and connecting mechanism. The sealing and connecting mechanism comprises an upper flange plate and a lower flange plate. One side of the upper flange plate is connected with the upper hemisphere in a sealed mode. One side of the lower flange plate is connected with the lower hemisphere in a sealed mode. The upper flange plate is detachably connected with the lower flange plate. The other side of the upper flange plate abuts against and is connected with the other side of the lower flange plate in a sealed mode. The detachable ball sealer is divided into the two hemispheres with the same structure, the two hemispheres are connected through bolts and nuts in the sealed mode, and therefore the ball sealer is convenient to assemble and disassemble; in this way, the detachable ball sealer can be used repeatedly, resource waste is avoided, and cost is further reduced; the upper hemisphere and the lower hemisphere adhere to the flange plates respectively, and an O-shaped ring is placed between the two flange plates so that the two flange plates can be connected in the sealed mode; in this way, sealing is reliable and maintenance is easy.
