Embodiment 1
[0030] A composite sealing device with super amphiphobic surface for floating roof storage tanks and its installation method, such as figure 1 As shown, the composite sealing device with superamphiphobic surface for floating roof storage tanks includes pressure bearing plate, diaphragm, labyrinth groove, secondary sealing sponge, upper fixing plate, bolts, gaskets, nuts, springs, rubber straps, primary Sealing sponge, outer support plate, lower fixed plate, inner support plate. The primary seal includes an upper fixing plate, a spring, a rubber strap, a primary sealing sponge, an outer supporting plate, a lower fixing plate, and an inner supporting plate. Each group of primary seals uses three springs to increase reliability, and a group of springs is arranged every one to two meters along the circumferential direction of the storage tank. Under the joint elastic force of the primary sealing sponge and the spring, the primary sealing device is closely attached to the tank wal...
Embodiment 2
[0043] According to the conditions of Embodiment 1, the upper and lower fixing plates 6 and 15 are respectively on the upper and lower sides of the rubber strap 12, and the upper and lower fixing plates 6 and the lower fixing plates 15 fix the upper and lower positions of the rubber strap 12 to ensure that the upper and lower positions of the rubber strap 12 can be adjusted with the floating disc. 10 up and down movement. When the floating plate 10 goes up, the primary sealing sponge 13 and the secondary sealing sponge 5 are deformed, and the whole is inclined downward. Under the action of the upper fixing plate 6 and the lower fixing plate 15, the primary sealing sponge 13 can be kept stable without overturning. The secondary sealing sponge 5 can also remain stable under the constraints of the upper fixing plate 6 , the diaphragm 3 and the pressure bearing plate 2 . When the floating plate 10 descends, the primary sealing sponge 13 and the secondary sealing sponge 5 will be ...
Embodiment 3
[0045] According to the conditions of Example 1, the width of the primary sealing sponge 13 is larger than the gap between the tank wall 1 and the floating plate 10. For the floating roof storage tank with severe deformation of the tank wall 1, the primary sealing sponge 13 and the spring 11 can ensure that the rubber band 12 and the tank wall 1 are kept in close fit. For example, when the gap between the tank wall 1 and the edge of the floating plate 10 is 250mm, the width of the primary sealing sponge 13 is 400mm, and the overall shape and width of the secondary sealing sponge 5 should fully consider the shape of the pressure plate and the floating size of the gap, and cannot be generalized. When the edge gap of the floating plate 10 becomes smaller, the primary sealing sponge 13 is squeezed and compressed, and is tightly attached to the tank wall 1 under the joint elastic force of the elastic sealing sponge and the spring 11; the secondary sealing sponge 5 can be pressed aga...
