Description

A storage tank sealing assembly

technical field

The utility model relates to the technical field of seals, in particular to a storage tank sealing assembly.

Background technique

Seals are materials or parts that prevent fluid or solid particles from leaking from adjacent joint surfaces and prevent external impurities such as dust and moisture from invading parts of machinery and equipment. The storage room temperature of the seal is preferably below 30 ℃ to avoid high temperature aging of the seal. The seals must be stored in a sealed package to avoid contact with moisture or dust in the air; the seals must be protected from strong light exposure to prevent the seals from being eroded by ozone in the air or prematurely aged. The factors affecting the performance of various seals are different, such as mechanical seals (packing seals, etc.) affecting factors such as temperature, medium, wear, pressure, etc. In recent years, the production and quality of rubber sealing products in my country have gradually entered a new stage, new era. However, these alone are far from meeting the needs of the development of other industries for the standardization and serialization of various rubber sealing products. Especially compared with international advanced countries, my country's products have both product quality and product variety. quite a big gap.

At present, when the existing paint cans are used for many times, due to repeated opening and closing, the sealant smeared on the original can lids will be consumed, resulting in poor sealing effect when the cans are sealed multiple times. The toxic gas that will lead to the volatilization of the paint will be released, which will pose a threat to the health and safety of personnel, and will also affect the quality of the paint. Therefore, we propose a storage tank sealing assembly to solve the above problems.
