Embodiment Construction

[0026] Such as figure 1 As shown, the high-pressure gas cylinder used for the transportation vehicle is a steel-lined glass fiber hoop-wound gas cylinder with a volume of 200 L to 400 L and a working pressure of 25 MPa to 35 MPa. The high-pressure gas cylinder includes a barrel section located in the middle, two bottle mouths located at both ends and a head connecting the barrel section and the bottle mouth, and its walls include: an inner tank 1 made of steel; A bonded coating 2 made; a composite material layer 3 made of glass fiber-epoxy system composite material; an outer protective film.

[0027] The liner 1 is made of chromium-molybdenum steel pipes in the way of spinning and closing. It provides space for storing compressed natural gas, directly contacts with the filling medium, acts as a seal and holds a part of the pressure. After the liner 1 is processed and shaped, heat treatment is required. The steps are: put the liner in a heating furnace, heat it to 860°C to 910...

Abstract

The invention provides a high-pressure gas cylinder for a gas transportation vehicle. The high-pressure gas cylinder comprises a barrel body section which is positioned in the middle, two cylinder openings which are positioned at two ends respectively, and end sockets which are connected with the barrel body section and the cylinder openings, wherein the wall of the high-pressure gas cylinder sequentially comprises an inner container which is made of steel, a combined coating layer which is made of a polyurethane material, a composite material layer which is made of a glass fiber-epoxy composite material, and an outer protection film from inside to outside. The high-pressure gas cylinder has the advantages that: by adopting the steel inner container and the composite material layer with a glass fiber-epoxy system, the fatigue property and the impact resistance are high, and a special requirement of the high-pressure gas cylinder for the gas transportation vehicle can be met; and the outer protection film is wrapped outside the composite material layer, so that a phenomenon that the wet air in the air and corrosive substances corrode the outer surface of the compound material layer, and thus the property of the gas cylinder is influenced can be avoided.

Description

technical field [0001] The invention relates to the field of manufacturing high-pressure gas cylinders, in particular to a high-pressure gas cylinder used on a wagon. Background technique [0002] With the popularity and development of CNG vehicles, high-pressure gas transport semi-trailers play an increasingly important role in the transportation of CNG gas. At present, CNG long-tube trailers are mostly used. Long-tube trailer gas cylinders are extra-large controlled steel cylinders. Several or more than ten cylinders are fixedly assembled on each trailer to store and transport gas. Due to the large loading capacity of the tube steel cylinders used for long tube trailers, the requirements for raw materials are high, and the manufacture is also relatively difficult, requiring some large equipment. At the same time, due to the limitation of vehicle weight and volume design, the luck of each trailer is also limited. [0003] Therefore, people pay attention to composite gas c...
