Description

Sealing structure and method for petroleum storage

Technical Field

The invention relates to the technical field of petroleum storage, in particular to a sealing structure and a method for petroleum storage.

Background

Petroleum refers to a mixture of gaseous, liquid and solid hydrocarbons, with natural occurrence. Although petroleum is classified into crude oil, natural gas liquid, natural tar and the like, it is customary to define "petroleum" as "crude oil", which is a viscous, dark brown liquid called "industrial blood", and the upper part of the crust has a petroleum reservoir, the main component of which is a mixture of various alkanes, cycloalkanes, and aromatics, and is one of the main objects of geological exploration, and petroleum is stored uniformly by using a petroleum barrel after being extracted, when petroleum is stored in the petroleum barrel by using a petroleum delivery pump, the conventional method is to insert a pipe connected to the output end of the petroleum delivery pump along the inlet of the petroleum barrel and then pour the petroleum into the barrel, and such a storage means is simple and easy to operate, but impurities such as dirt and dust adhered to the outer wall of the petroleum pipe are also mixed into the petroleum barrel along with the insertion of the pipe, the petroleum quality is influenced, the size of the feeding port is far larger than the diameter of the guide pipe, the oil field is in an unshielded field, external stains are blown into the gap between the feeding port and the guide pipe by wind in the petroleum infusion process, moreover, the feeding port of the petroleum barrel is generally sealed by a round cover with internal threads, so that the cover needs to be manually screwed off and screwed down before and after workers fill petroleum into the cylinder, however, in the case of a large amount of petroleum storage works, the same huge number of petroleum barrels need to be used, the repeated screwing of the cover not only wastes a lot of time, but also causes the problem that the tightness of the feeding port is reduced due to insufficient screwing degree of the cover due to fatigue of the workers under the heavy petroleum storage working pressure, in addition, after the guide pipe for storing petroleum into the petroleum barrel is not used for a long time, due to the viscosity of the residual oil on the inner wall, the inner wall of the conduit for storing oil drilled into the conduit becomes full of sand, which makes it extremely difficult to clean when it is put into use again; in addition, the rubber pad is usually added at the oil filling port in the structural design of other existing petroleum barrel sealing covers, a spring reset or coil spring reset structure is added in the rubber pad, so that the automatic sealing before and after the insertion of an external oil guide pipe and the oil transportation sealing performance in the insertion process are realized, but the design structure still needs the process of screwing the spiral cover, and the spring or the coil spring structure is generally of a metal structure, so that oil is corroded, the oil barrel sealing cover is easy to lose efficacy after long-time operation, and even the oil barrel sealing cover falls into the oil barrel.

In view of this, we propose a seal and method for oil storage.
