Novel annular pressure container and manufacturing process thereof

The invention discloses a novel annular pressure vessel and a manufacturing process thereof, the novel annular pressure vessel comprises a pressure vessel body, and the wall surface of the pressure vessel body is sequentially provided with an inner container, a mechanical enhancement layer and a protective layer from inside to outside; the inner container is an annular cavity, a valve is arranged on the inner ring side wall face of the pressure container body and installed on the wall face of the pressure container body through a valve seat, and an inner container end clamping groove and an inner container shoulder clamping groove are formed in the valve seat. The inner container end and the inner container shoulder on the inner container of the pressure container body are connected in a clamped mode. The pressure container is integrally arranged to be annular, and the valve seat is arranged on the inner side of the annular container, so that the mechanical strength and the air tightness of the pressure conta
