Oil storage tank with sealing property

Abstract

The invention relates to an oil storage tank with the sealing property. The oil storage tank comprises two or more supports and a tank body arranged on the supports, wherein the supports and the tank body are fixedly connected. The oil storage tank is characterized in that the tank body comprises a tank wall layer, a static conducting coating arranged in the tank wall layer and an anticorrosive layer arranged outside the tank wall layer; a vacuum layer is formed between the tank wall layer and the anticorrosive layer, and an oil inlet, an oil outlet and an inspection port all communicated with the cavity of the static conducting coating are formed in the top of the tank body; sealing covers are installed on the oil inlet and the oil outlet respectively. The oil storage tank has the advantages that the structure is simple, use and installation are convenient, the n-shaped sealing covers integrally formed are used for connecting the oil inlet to the oil outlet through threads, and the sealing stability of the oil storage tank is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of oil storage tanks, and in particular relates to an oil storage tank with sealing performance. Background technique [0002] In the field of oil storage, the oil storage tank is the main container for storing oil, and it is the main equipment of the oil depot. According to the material, oil storage tanks can be divided into metal oil tanks and non-metal oil tanks; according to their location, they can be divided into underground oil tanks, semi-underground oil tanks and above-ground oil tanks; according to the installation form, they can be divided into vertical and horizontal; according to their shape, they can be divided into Cylindrical, square box and spherical. Horizontal cylindrical oil tanks are widely used. Because it has the ability to withstand higher positive and negative pressures, it is beneficial to reduce the evaporation loss of oil products, and also reduces the risk of fire. [0003] In...

AI Technical Summary

Problems solved by technology

[0003] In addition to the continuous improvement of materials, the existing oil storage tanks have higher and higher requirements for sealing performance. Since oil leakage will cause major accidents, the oil storage tank products must meet various standards set by the state. The existing oil storage tanks Some tanks are buried in the ground, and they are eroded by underground water vapor and electrolytic corrosion all the year round. There are obvious shortcomings in quality and life, and obvious shortcomings in terms of safety, economy, and environmental protection;

[0004] In addition, the oil inlet and outlet of the traditional oil storage tank are mainly sealed by flange connection with gaskets. However, the sealing performance of this connection method is not stable, and after a period of use, it is easy to cause rainwater to leak into the tank. In the body, it brings inconvenience and safety hazards to the use
