Reservoir walls, described gripper shoe top is fixed on the vertical plane of secondary edge plate by bolt, nut.
The material of described flexible member is anti-flammability elastic foam.
The beneficial effects of the utility model are：
1. the immersion type sealing device described in the utility model be installed on storage tank shell and inner floating roof annular spacing it
Between, preferably can seal with tank skin so that volatilize gas concentration and substantially reduce, eliminate the potential safety hazard of detonation.
2. because bellows band is arranged on the side of the lateral frame board of inner floating roof, and there is gripper shoe to catch on flexible member, press
Tight bellows band, rolls up and down so as to effectively prevent inner floating roof bellows band when running up and down, greatly improves the leaching
The service life of liquid formula sealing device, reduces cost.
3. because in bellows band bottom immersion storage medium so that the sealing effectiveness of the sealing device is greatly improved.
