Vehicle-mounted hydrogen storage bottle valve seat structure and installation mode

Abstract

The invention discloses a vehicle-mounted hydrogen storage bottle valve seat structure. The structure structurally comprises a non-metal inner container, carbon fiber winding layers and a valve seat structure body, wherein the valve seat structure body comprises metal inserts and skirt outer sleeves; the metal inserts are tightly fused to the two ends of the non-metal inner container respectively; the skirt outer sleeves are tightly connected outside the fusion positions of the metal inserts and the non-metal inner container in a sealed mode respectively; the carbon fiber winding layers coat the outer sides of the two skirt outer sleeves and the non-metal inner container tightly; and a hydrogen inlet and outlet channel is arranged in center holes of the metal inserts and center hole of the skirt outer sleeves and communicated with the interior of the non-metal inner container. According to the installation mode, the metal inserts and the non-metal inner container are tightly welded, the metal inserts and the skirt outer sleeves are in threaded sealing connection, and the skirt outer sleeves and the non-metal inner container are firmly wound through carbon fibers. The forming quality of the non-metal inner container is facilitated, the pressure capability of a hydrogen storage bottle is improved, the tensile strength of a valve seat and the hydrogen storage bottle is enhanced, and the air permeability and the sealing performance of a hydrogen storage bottle connector are guaranteed.

Description

technical field [0001] The invention relates to the field of valve seat structure of a high-pressure container, in particular to a valve seat structure of a vehicle-mounted hydrogen storage bottle and an installation method thereof. Background technique [0002] With the consumption of fossil energy, the aggravation of air pollution and greenhouse effect, people have been constantly exploring, developing and utilizing clean energy. Hydrogen energy battery vehicles are new energy vehicles vigorously advocated by our country, which have outstanding advantages in improving energy structure and reducing pollution emissions. [0003] On-board hydrogen storage technology is the key to the development of hydrogen fuel cell vehicles, which directly affects the mileage and cost of battery vehicles. Vehicle-mounted hydrogen storage bottles are mainly aluminum liners and non-metal liner hydrogen storage bottles with mature technology. 35MPa pressure hydrogen storage bottles are wide...

AI Technical Summary

Problems solved by technology

Although the non-metal liner has the advantages of corrosion resistance and light weight, there are technical difficulties in liner production, liner and metal valve seat welding, interface sealing, carbon fiber winding, etc.
