Embodiment 1

[0023] at 100,000 m 3 The floating roof storage tank is taken as an example to illustrate the implementation of the floating disk sealing device.

[0024] Such as figure 1 , figure 2 As shown, the edge height of the floating chamber of the floating roof storage tank is 1200mm, and the average distance between the floating chamber and the tank wall is 250mm. Considering the deformation of the tank wall, the maximum gap between the tank wall and the floating chamber is 400mm, and the minimum gap is 100mm.

[0025] The height of the shoe is 1800mm, the width of a single shoe is 2000mm, the thickness of the shoe is 4mm, and it is made of carbon steel.

[0026] First weld the pin holes on the side edge of the floating plate. The distance between adjacent pin holes is 1000mm. The distance between the pin holes and the bottom edge of the floating warehouse is 500mm. , the width of the shoe support plate is 700mm, the length is 2000mm, and the thickness is 4mm. The oil and gas di...

Abstract

The invention relates to a self-adaption float tray seal ring with a self-extinguishing function, and mainly solves the problem of poor safety caused by oil gas leakage in the prior art. The inventionadopts the technical scheme that the self-adaption float tray seal ring with the self-extinguishing function comprises a primary sealer and a rain shelter plate, wherein the primary sealer is formedby a metal shoe plate, a shoe plate support plate, a shoe plate support shaft, a balance weight liquid bag, a premixed foam solution and an oil gas membrane, so that the problem is well solved, and the self-adaption float tray seal ring with the self-extinguishing function can be applied to float tray sealing.

Description

technical field [0001] The invention relates to an adaptive floating disk sealing ring with automatic fire extinguishing function. Background technique [0002] Due to oil and gas leakage at the sealing ring of the current floating roof storage tank, flash explosion accidents are prone to occur after lightning strikes and open flames, resulting in a sealing ring fire. [0003] Most of the current sealing rings use soft seals, and a few use liquid-filled seals. After many storage tanks have been in operation for several years, the tank wall often deforms irregularly due to the settlement of the tank foundation, resulting in a greatly reduced roundness of the storage tank. After the tank wall is deformed, there will be gaps between the floating disc sealing device and the tank wall, resulting in poor sealing of the floating disc sealing ring, resulting in oil and gas leakage and the formation of combustible gas. After a flash explosion accident, the sealing ring is burned, f...
