Embodiment 1

[0019] This patent adopts a composite soft seal structure, which assembles the elastic foam-filled seal and the liquid-filled seal together to give full play to the advantages of these two seals. At the same time, the length of the rubber bag is extended to increase the contact between the rubber bag and the tank wall area.

[0020] Such as figure 1 As shown, the soft sealing device is composed of three parts, namely elastic foam-filled rubber bag, liquid-filled rubber bag and elastic foam, in addition there are rubber bag fixing plate, liquid injection port of liquid-filled rubber bag and other accessories.

[0021] The liquid-filled rubber bag is placed in the middle of the whole device, and elastic foam is set on both sides or one side. The resilient foam filled side is placed adjacent to the side of the tank wall. When the gap between the tank wall and the floating plate is small, the gap between the liquid-filled rubber bag and the floating plate does not need to be ins...

Abstract

The invention relates to a composite type soft sealing method which mainly solves the problem that the sealing effect is poor in the prior art. According to the composite type soft sealing method, a composite type soft sealing device is adopted to seal the space between a floating pan and a tank wall of a storage tank and comprises an elastic foam filling rubber bag, a liquid filling rubber bag, elastic foam and a fixing pressure board, the elastic foam filling rubber bag is arranged in the space between the tank wall and the floating pan of the storage tank, the face, making contact with the tank wall, of the elastic foam filling rubber bag is a zigzag surface, and the elastic foam filling rubber bag is filled with the liquid filling rubber bag and the elastic foam. The technical scheme that the space between the liquid filling rubber bag and the tank wall of the storage tank is at least filled with the elastic foam well solves the problem that the sealing effect is poor in the prior art, and the composite type soft sealing method can be used for sealing of floating roof storage tanks.

Description

technical field [0001] The invention relates to a composite soft sealing method. Background technique [0002] At present, most of the seals between the floating plate and the tank wall of external floating roof storage tanks are filled with elastic foam, mechanical seals or liquid-filled seals. These sealing devices are affected by factors such as the ellipticity of the tank wall and the deformation and failure of the filler during operation. , it is difficult to maintain an effective seal with the tank wall, resulting in oil and gas leakage, which has become an important hidden danger of the explosion accident of the floating roof sealing ring. [0003] CN201210431694.5 relates to a composite sealing device applied to an internal floating roof storage tank, which can not only greatly improve the sealing effect, but also remove the corrosion products attached to the tank wall in time, thereby greatly reducing the occurrence of combustion in the tank caused by the spontaneou...
