Abstract

The invention discloses a corrugated type sealing device of an oil tank guide post. The corrugated type sealing device comprises semi-corrugated tubes, two semicircular sealing clamp rings, a bottom ring-shaped sealing part, guide ropes and N groups of transverse metal ring sleeves, wherein in the N group of transverse metal ring sleeves, each group of transverse metal ring sleeves comprises M transverse metal ring sleeves; each group of transverse metal ring sleeves is positioned on the same horizontal plane, and is uniformly distributed along the circumferences of the semi-corrugated tubes; M is greater than or equal to 2; the semi-corrugated tubes are fixed by virtue of one group of transverse metal ring sleeves from space to space; and M guide ropes sequentially pass through the plurality of groups of transverse metal ring sleeves from top to bottom for supporting and fixing the semi-corrugated tubes correspondingly. According to the corrugated type sealing device, by virtue of a plurality of protective sections, the semi-corrugated tubes are connected into a sealed space which adapts to maximum liquid level and minimum liquid level of a floating roof, so that oil gas volatilization is restrained, energy consumption is reduced, the atmospheric environment and the personal safety are protected, and safe operation of an oil storage tank is ensured.

Description

technical field [0001] The invention relates to the field of oil tank sealing, in particular to a corrugated sealing device for a guide column of an oil tank. Background technique [0002] Atmospheric pressure metal storage tanks are vertical cylindrical welded steel storage tanks for storing liquid petroleum, petroleum products and other media. According to the structure, it can be divided into: fixed roof tank, external floating roof tank and internal floating roof tank. Among them, the floating roof of the inner and outer floating roof tanks is equipped with anti-rotation and guide columns of the centering mechanism. According to the requirements of the standard specification, a dipstick or guide column should be installed on the top of the tank, so as to measure the quality of the oil or prevent it. The floating roof rotates. In order to ensure that the oil inside and outside the tube can flow freely, the guide tube is opened with two symmetrical rows of holes with a d...
