Performance Characteristics of Paddlewheel Horizontal & Vertical Fast-opening Blind:

1 The rotating part of the fast-opening blind and the sealing part are coaxial double blind. The rotating of the pallet uses the ahead axial thrust produced by its inclined plane to pull the blind translate ahead. The sealing ring gets extruding to achieve the translation sealing; so the sealing part will not be broken.

2 The structure is simple and clear. It is only necessary to put the wheel-hub on the wheel depression, and then rotate the screw with the spanner for 90-720°. An operator can safely open the blind in a minute without any special instrument for non-disclosure.

3 When the closure is in place, installing the safety interlocking meets increasing pressure only when all parts are tightened on predestinate operation parts. The head cover cannot rotate after installing the safety interlocking. After the system discharges, the safety interlocking should be opened first to vent all pressure in the container, and then the head cover can be opened.
