Abstract

The invention relates to a self compensating type inflatable soft sealing method with remote control function, and the method mainly solves the problems of the prior art that the sealing device and the tank wall cannot be laminated tightly, the filler is nonpersistent or is not easy to replace, and the remote control cannot be achieved. According to the self compensating type inflatable soft sealing method with remote control function, the soft sealing device is adopted for sealing the storage tank floating disc and the tank wall; the soft sealing device mainly comprises an air bag, an air bag fixing belt, an air bag joint, a pressure gas storage tank, a pressure wireless sensor and an air filling pipe; the problems can be solved by the technical scheme and the self compensating type inflatable soft sealing method with remote control function is applied to the sealing operation of the floating roof storage tank.

Description

technical field [0001] The invention relates to a self-compensating inflatable soft sealing method with remote control function. 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...
