Description

LNG gas cylinder vacuum port protection subsides

Technical Field

The invention relates to the technical field of LNG (liquefied natural gas) cylinders, in particular to a protective sticker for a vacuum port of an LNG cylinder.

Background

The inner container of the LNG cylinder is used for storing low-temperature (-162 ℃) LNG, the outer shell mainly serves as an interlayer space between the inner container and the stroke, the interlayer space is filled with filler materials, and the interlayer space is pumped into high vacuum, so that the stroke is good in heat insulation effect. Once the vacuum in the interlayer space is broken, the LNG cylinder loses its insulation, causing failure of the LNG cylinder. At present, the existing measures are that a sealing plug is arranged at a vacuumizing hole of an LNG (liquefied natural gas) cylinder, an interlayer vacuum cavity of an inner container and an outer container is isolated from the outside atmosphere, the vacuum effectiveness of the interlayer is guaranteed, and meanwhile, a warning slogan is pasted at the edge position of a vacuum plug to prompt a user to mistakenly touch the vacuum plug during unnecessary maintenance. The LNG gas cylinder three-pack manual is specified, and in the warranty period, when the vacuum degree of a container is reduced to a specified value, a gas cylinder production enterprise needs to perform corresponding three-pack service on a user. Therefore, when the three-pack problem occurs due to the reduction of the vacuum degree, the LNG cylinder production enterprise needs to consider what the root cause of the vacuum reduction is, and it is necessary to identify and prevent the malicious behavior of others by adopting corresponding measures in order to avoid artificially and consciously pulling out the vacuum plug, destroying the vacuum degree of the LNG cylinder, and cheating the three-pack service.

The prior art means at present: firstly, adopt metal protection casing, to take out the vacuum port parcel and weld on the LNG gas cylinder bottle, increase the degree of difficulty of people touching the sealing plug and after the destruction in prosthetic degree of difficulty. Secondly, a sealing plug form is adopted, the opening port of the sealing plug is sealed, and the difficulty of pulling out the sealing plug is increased. The two technologies only increase the difficulty and cost of breaking the vacuum artificially, and cannot completely avoid the problem. Meanwhile, for LNG cylinder production enterprises, difficulty and cost of maintaining the vacuum degree of the LNG cylinder are increased. Therefore, a novel LNG cylinder vacuum port protection paste is provided to solve the problems.
