Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] figure 1 It is a schematic diagram of the assembly structure of the steel floating plate opening sealing device used to install the liquid level gauge. As shown in the figure, the sealing device includes: a standpipe 1 , a sealing assembly 2 and a sealant cover 3 .

[0020] The standpipe 1 is a straight pipe. The lower end of the standpipe 1 is welded and sealed with the opening opened on the steel floating plate. The upper end of the riser 1 is provided with a flange.

[0021] The lower end opening of the sealing assembly 2 corresponds to the upper port of the standpipe 1 , and a flange is correspondingly provided to connect with the flange at the upper end of the standpipe 1 . The upper part of the sealing assembly 2 is a tapered pipe, and the larger opening of the tapered pipe is the upper opening of the sealing assembly 2 .

Abstract

The invention provides a steel floating roof opening sealing device used for mounting a level instrument, which is characterized in that: the steel floating roof opening sealing device comprises a riser, a sealing assembly and a sealing rubber cover; the lower end of the riser is welded with an opening on the steel floating roof for sealing; the upper end of the riser is provided with a flange; the lower opening of the sealing assembly corresponds to the upper end port of the riser and is correspondingly provided with a flange; the flange at the lower opening of the sealing assembly is butted with the flange at the upper end of the riser; the upper part of the sealing assembly is provided with a tapered tube; a larger opening of the tapered tube is the upper opening of the sealing assembly; the sealing rubber cover is conical; the shape of the sealing rubber cover is matched with that of the tapered tube at the upper end of the sealing assembly; and the center of the sealing rubber cover is provided with a through hole. The sealing device is provided with the sealing assembly and the sealing rubber cover to reduce the contact area of oil and air to be equal to the pore size of the through hole, so the contact area of the oil and the air is greatly reduced.

Description

technical field [0001] The invention relates to a sealing device, in particular to a sealing device for sealing an opening on a steel floating plate for installing a liquid level gauge in an oil storage tank, and belongs to the technical field of oil tank monitoring. Background technique [0002] The liquid stored in the oil storage tank is generally a volatile liquid, such as gasoline, ethanol, etc. For this volatile liquid, when the air on its surface does not reach a certain concentration, the liquid will continue to volatilize and change from liquid to gas. When the gas (oil vapor) on the surface reaches a certain concentration, the medium will gradually Stop volatile. [0003] In actual industrial implementation, the continuous volatilization of this oil vapor will bring a lot of loss and economic loss to the storage of the petrochemical industry. According to statistics, 5.184 kilograms of gasoline can be volatilized in 24 hours per square meter of gasoline surface. ...
