Embodiment Construction
[0016] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0017] A heat-insulated liquefied natural gas cylinder, comprising an outer shell, an inner tank, a saddle and an outer shell sliding support seat arranged on the outer shell, one end of the inner tank is fixedly connected to the outer shell through the saddle, and the other end of the inner tank is passed through the The sliding support seat of the shell is movably connected with the bottom of the shell; the top of the inner tank is sealed by the outer shell to form a heat-insulated vacuum space, and a heat-insulating material is also filled between the outer shell and the inner tank. In the present invention, two-stage safety valves with different opening pressures are provided. The heat insulating material is a multi-layer heat insulating material of glass fiber paper+aluminum foil; the outer casing and the inner tank are made of austenitic ...

The invention discloses a heat insulation type liquefied natural gas cylinder. The heat insulation type liquefied natural gas cylinder comprises a shell, an inner container, a saddle and a shell sliding supporting seat arranged on the shell. One end of the inner container is fixedly connected with the shell through the saddle, and the other end of the inner container is movably connected with the bottom of the shell through the shell sliding supporting seat. The top end of the inner container is sealed through an outer sealing head and the shell to form a heat-insulating vacuum space. the space between the shell and the inner container is filled with a heat insulating material. According to the heat insulation type liquefied natural gas cylinder, support distribution of the inner container and the shell is reasonable and reliable, the inner container is supported by a non-metallic material small in heat conductivity coefficient and excellent in mechanical property, one end of the inner container is fixedly connected with the shell, and the other end of the inner container is supported in a sliding mode, so that the stress may caused by shrinkage when liquefied natural gas (LNG) is contained in the inner container is effectively controlled.
Description
technical field [0001] The invention relates to the technical field of automobile energy, in particular to an insulated liquefied natural gas cylinder capable of storing and providing fuel. Background technique [0002] With the rapid development of the industrial economy, the world's affairs are paying more and more attention to the protection of the environment. Traditional automobiles use gasoline as fuel, and the exhaust gas emitted by automobiles has caused serious pollution to the environment. In order to change this situation and adjust the energy structure, all affairs in the world are studying the use of combustible gas instead of gasoline and the use of new automobile fuels. . At present, there are mainly two types of combustible gas that have been put into trial use. One is liquefied petroleum gas. The use of liquefied petroleum gas can reduce the unqualified exhaust emissions. The impact of this has restricted the further promotion and use of liquefied petroleu...
