Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] figure 1 It is a schematic diagram of the assembly structure of the aluminum floating plate opening sealing device used to install the liquid level gauge. As shown in the figure, the sealing device includes: an oil sealing pipe 1 , a sealing assembly 2 and a sealant cover 3 .

[0022] The oil sealing pipe 1 is arranged on the lower side of the aluminum floating plate, and its upper port corresponds to the opening on the aluminum floating plate. The upper port of the oil sealing pipe 1 is provided with a flange, which is fixed to the opening on the aluminum floating plate by bolts.

[0023] The lower port of the sealing assembly 2 corresponds to the opening on the aluminum floating plate. A flange is provided at the lower port of the sealing assembly 2, and is fixed to the opening on the aluminum floating plate through bolts. Through the abov...

Abstract

The invention provides an aluminous floating disc opening sealing device for mounting a liquid level apparatus. The device is characterized by comprising an oil sealing tube, a seal assembly and a seal rubber cover, wherein the oil sealing tube is arranged on the lower side of an aluminous floating disc and the upper end opening of the oil sealing tube corresponds to an opening reserved on the aluminous floating disc; a flange is arranged on the upper end opening of the oil sealing tube; the lower end opening of the seal assembly corresponds to the opening reserved on the aluminous floating disc; a flange is arranged on the lower end opening of the seal assembly; the upper part of the seal assembly is a tapered tube and the bigger opening of the tapered tube is the upper end opening of the seal assembly; the seal rubber cover is round table-shaped; the shape of the seal rubber cover is matched with that of the tapered tube at the upper end of the seal assembly; and a through hole is reserved in the centre of the seal rubber cover. The contact area of oil and the air is reduced to the size of the aperture of the through hole by arranging the seal assembly and the seal rubber cover, so that 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 an aluminum 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 surfa...
