Abstract

The invention belongs to the technical field of fire safety of oil storage tanks, and particularly relates to an inflatable oil-gas-free sealing structure of an external floating roof oil tank. According to the technical scheme, the inflatable oil-gas-free sealing structure of the external floating roof oil tank comprises an annular primary sealing structure and an annular secondary sealing structure which are connected to a floating disc, and the primary sealing structure and the secondary sealing structure are located between a tank wall and the floating disc; the secondary sealing structure is connected with an inflatable capsule, an embedded connecting nut is fixed in the inflatable capsule, the secondary sealing structure comprises a rain baffle, one end of the rain baffle is connected to the floating disc, and the embedded connecting nut is connected with the rain baffle through an inflatable capsule fixing piece. One end of the inflatable capsule fixing piece is connected with the embedded connecting nut, and the other end of the inflatable capsule fixing piece penetrates through hole sites of the rain baffle, a supporting limiting plate and an oil separation film and is fixed to the rain baffle, so that reliable connection is guaranteed. The invention provides the inflatable oil-gas-free sealing structure of the external floating roof oil tank.

Description

technical field [0001] The invention belongs to the technical field of fire safety of oil storage tanks, and in particular relates to an inflatable oil-gas-free sealing structure for an oil tank with an outer floating roof. Background technique [0002] There is an annular gap of about 250mm between the outer edge plate of the floating roof of the outer floating roof oil tank and the wall plate of the oil tank. This gap is a necessary space for the floating roof to run up and down, ensuring that the floating roof can rise and fall normally. However, this gap will form an annular space where the oil surface is exposed, and the oil surface is in contact with the atmosphere, which becomes the main factor for the evaporation loss of oil. In order to block the contact between the exposed oil surface in the annular space and the atmosphere and prevent the volatilization of oil and gas, a sealing device is usually installed in this space. The sealing device of the external floatin...
