Description

Technical Field

[0001] The utility model relates to the technical field of connection structures, in particular to a composite gas cylinder liner connection structure. Background Art

[0002] Gas cylinders are pressure-bearing equipment with explosion hazards, and the media they contain are generally flammable, explosive, toxic, and highly corrosive. The use environment is more complex and harsh than other pressure vessels due to the characteristics of mobility, repeated filling, unstable operators, and changing use environment. Once a gas cylinder explodes or leaks, it often causes fire or poisoning, or even catastrophic accidents, resulting in serious property losses, casualties, and environmental pollution. To ensure the safe use of gas cylinders, in addition to requiring it to meet the general requirements for pressure vessels, some special regulations and requirements are also required. With the widespread application of composite gas cylinders, the requirements for the quality and strength of composite gas cylinders are becoming higher and higher. Therefore, it is particularly important to produce composite gas cylinders with excellent performance and high pass rate.

[0003] At present, the publication number CN207569518U discloses a connection structure between the inner liner and the outer liner of a large-volume natural gas cylinder. The inner liner and the outer liner of the gas cylinder are rigidly connected at the front end and elastically connected at the rear end. The rigid connection adopts a middle tube sleeved on the outside of the small tube, and there is a gap between the middle tube and the small tube. The small tube and the middle tube are connected at one end by a neck tube connection cover. The inner liner front head and the front head reinforcement ring are welded on the outer wall of the middle tube. A gasket made of glass fiber reinforced plastic material is used for transition fit between the middle tube and the small tube, so that the middle tube and the small tube are in an integrated structure. One end of the glass fiber reinforced plastic gasket protrudes radially outward and is provided with an edge, and one side of the edge conflicts with the end of the middle tube. The glass fiber reinforced plastic gasket is used for transition fit between the middle and small tubes, and is smashed in with a tool. The function here is to connect the front ends of the middle tube and the small tube to prevent the fatigue load from causing the middle tube to be deformed by force. The small tube and the middle tube are connected as a whole by the glass fiber reinforced plastic gasket. The thermal conductivity of glass fiber reinforced plastic is very small, which has little effect on the static evaporation rate of the bottle body.

[0004] In order to solve the problem of inner liner connection in the above technical solution, the existing technology adopts a transition fit between the fiberglass gasket and the middle and small tubes, and hammers them in with a tool. The role here is to connect the front ends of the middle tube and the small tube to prevent the middle tube from being deformed due to fatigue load. The small tube and the middle tube are connected into a whole with a fiberglass gasket. However, the connection is not convenient and flexible enough, which leads to the problem of insufficient connection efficiency and convenience. Utility Model Content
