Abstract: A device for forming a V-shaped full-composite pressure vessel includes a semi-cylinder body mold, where the length of a cylinder body part of the semi-cylinder body mold is half of the length of a cylinder body of a processed pressure vessel; a groove for placing a valve seat is reserved at one end of a dome part of the semi-cylinder body mold, and a fiber yarn-dividing ring is mounted at the other end; the semi-cylinder body mold is connected to the valve seat through a spline; and the valve seat and the fiber yarn-dividing ring are in threaded connection with a rotating shaft of fiber winding equipment. According to this disclosure, a liner-free pressure vessel can be manufactured completely by processing a composite material, so the mass of the pressure vessel can be reduced. Furthermore, the mold is not required to be dissolved and taken out.

Abstract: An inflation control apparatus includes seal heads at ends of a container liner on a rack; a rotary inflation connector includes a static component and a rotating component. The rotating component is connected with the seal head; an inflation core tube is in the container liner, air holes are in the inflation core tube, and the two ends of the inflation core tube are connected with the static component of the rotary inflation connector respectively. A temperature and pressure sensor is in the container liner; an air compressor provides air for an air heater, the air heater introduces the heated air into an air inlet of the inflation core tube, an air outlet of the inflation core tube is connected with an air inlet of a flow regulating valve, and an air outlet of flow regulating valve is connected with an air inlet of the air compressor.
