Plastic inner container carbon fiber fully wound gas cylinder and manufacturing method thereof

Abstract

The invention discloses a plastic inner container carbon fiber fully wound gas cylinder and a manufacturing method thereof. The manufacturing method comprises the step of cylinder opening assembling,wherein the outer surface of an inner container and a cylinder opening and a tail top needing to be mounted on the inner container are cleaned by absolute ethyl alcohol with the concentration being 99% or above, a sealing ring, a sealing gasket and the cylinder opening are assembled to form a to-be-assembled body, the to-be-assembled body is mounted on the cylinder opening of the inner container,the tail top is mounted at the tail of the inner container and is opposite to the cylinder opening, the to-be-assembled body, the tail top and the inner container are subjected to cold assembling, andit is guaranteed that the gas cylinder cannot shrink again under the work temperature of the inner container, the to-be-assembled body and the tail top. The problems that the inner container and a fiber winding layer are prone to being separated, and the sealing performance fails are solved, the sealing effect is better, the inner container and the fiber winding layer are bonded closely, layeringis not prone to happening, and the use stability of the gas cylinder is improved.

Description

Technical field [0001] The invention particularly relates to a carbon fiber fully wound gas cylinder with a plastic liner and a manufacturing method thereof. Background technique [0002] With economic development and the popularization and application of modern technologies, the new energy industry has been greatly developed, and the energy structure based on chemical fuels has been optimized. The conversion of new and old energy is the general trend, and the development of new energy vehicles requires matching Equipment: High-pressure gas cylinders, namely CNG / LNG cylinders for vehicles, with a nominal working pressure of 20MPa. When making high-pressure gas cylinders, the technical solution commonly used in this field is to use a plastic inner liner to heat and fill the inside with gas multiple times, so that the inner liner of the gas cylinder can be wound while maintaining the pressure. According to the traditional method It requires multiple fillings, which not only consum...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a method that solves the problem that the inner tank and the fiber winding layer are easy to separate, solves the problem of sealing performance failure, the better the sealing effect, the tighter the inner tank and the fiber winding layer are bonded, the less likely to be delaminated, and the improvement Plastic liner carbon fiber fully wound gas cylinder with improved stability in use of gas cylinder and manufacturing method thereof
