    Abstract: A bi-directional penetrating metal bottleneck structure of a type IV hydrogen storage tank is provided, which includes a metal valve seat, a plastic liner, and a fiber winding layer. A valve seat hole is formed on an inner side of the metal valve seat, and the metal valve seat includes an annular flange, a valve seat column section, and a valve seat extension. L-shaped through holes and radial penetrating holes are formed in the valve seat column section. The valve seat hole is an irregular through hole and is provided with an annular groove. The valve seat extension is provided with a winding inclined plane, a self-tightening conical surface, a circumferential groove, and axial penetrating holes. The plastic liner includes an inner plastic joint, an outer plastic joint, a tapered connecting section, L-shaped connectors, radial connectors, axial connectors, and a reinforcement section. A flared annular boss at an upper part of the inner plastic joint is tightly clamped and embedded in the annular groove, and a lower part of the inner plastic joint, the L-shaped connector and the radial connector enclose a “B”-shaped binding structure to wrap a lower part of the valve seat column section inside and outside. According to the present disclosure, binding fastening is achieved, a sealing effect is enhanced, and the reliability and stability of a connection between the plastic liner and the metal valve seat are ensured.

    Abstract: An example of a container is disclosed. The example disclosed herein comprises an impermeable container wall, a container releasing valve, and a gas vessel. The impermeable container wall defines the boundaries of an inner volume of the container. The container releasing valve is installed in the container wall to release gas from the inner volume of the container to the outside of the container. The gas vessel is installed in the inner volume of the container. The gas vessel comprises a gas vessel wall, a pressurized vessel gas, and a gas vessel releasing system. The gas vessel wall defines the boundaries of an inner volume of the gas vessel, wherein the gas vessel wall is impermeable and allows for a pressure difference between the inner volume of the gas vessel and an outer volume of the gas vessel. A pressurized vessel gas is enclosed within the inner volume of the gas vessel. And a gas releasing system is to release a certain quantity of the vessel gas to the inner volume of the gas container.
