(Summary description)The structure of the LNG vehicle bottle is divided into the inner container of the storage tank, the outer container of the storage tank, the interface valve of the storage tank, the LNG liquid level sensor and the insulation quilt. The storage tank is a high-vacuum insulated container for storing LNG. The main structure contains an inner tank and an outer tank, with a vacuum and heat insulation type in the middle. The high working pressure set for the inner tank is 1.59MPa, and the calculated pressure is taken as 2 times the high working pressure. The outer wall of the inner tank is wrapped with a multi-layer insulation material composed of glass fiber paper and smooth aluminum foil. The multi-layer material has the characteristics of low thermal conductivity, high insulation performance and light weight under high vacuum conditions. The interlayer is equipped with palladium oxide, molecular sieve, etc. to extend the vacuum service life. The outer shell design is mainly used to form a sandwich space with the inner tank to ensure a good insulation effect of the inner tank. The better the effect, the longer the storage time of LNG in the storage tank.
