Abstract

The invention discloses a FF buried oil tank with an anti-seepage well seat, which comprises a tank body and a well seat arranged on the tank body. Detachably connected cylinder cover, anti-consolidation upper cylinder, anti-leakage middle cylinder and anti-leakage lower cylinder, the well base includes the well base cylinder body and the internal pressure ring formed at the outer edge of the upper port of the well base cylinder body, The anti-leakage lower cylinder includes the lower cylinder body and the outer pressure ring edge formed in the lower cylinder body. The inner lower part of the outer pressure ring edge is processed with a first bevel angle, and the outer lower part of the inner pressure ring edge is processed with a second bevel angle. An annular cavity is formed between the bevel and the second bevel, and a floating ring for sealing the annular cavity is movably placed between the first bevel and the second bevel. Compared with the traditional sealing ring, the present invention has the advantage of better waterproof effect by arranging the anti-seepage component on the well seat, and can avoid the phenomenon of a large amount of water accumulation in the operation well.

Description

technical field

[0001] The invention relates to the technical field of oil storage, in particular to an FF buried oil tank with an anti-seepage well seat. Background technique

[0002] Double-layer glass fiber reinforced plastic oil tanks are also called FF buried oil tanks. The inner and outer layers are both glass fiber reinforced plastic tanks, which are superior to oil tanks with metal tanks in terms of internal and external corrosion resistance. During the burying of the FF buried oil tank, the well base and the part below the well base are backfilled with high-quality fine sand (without stones and harmful organic matter), and the part above the well base is solidified with concrete as the ground support. In the existing FF buried oil tank well base, the operation well and the well base are mostly connected by flanges, which are mainly used to prevent fine sand from entering the operation well and affecting the later maintenance and repair operations, but this structure...
