High-temperature-resistant self-sealing gas cylinder

Abstract

The invention discloses a high-temperature-resistant self-sealing gas cylinder comprising an inner container, a composite material winding layer, an elastic layer and a heat insulation layer from inside to outside, the inner container comprises an inflation and deflation connector part at the front end and an inner container body, and the inner container body and a shell of the inflation and deflation connector part at the front end are connected in a welded mode to form the inner container; the inflation and deflation connector part comprises a spring, a valve element, a piston and a rubber ring, one end of the spring is installed in a clamping groove in the inner container body, the other end of the spring is connected with the valve element, the valve element is pressed against the inclined face of the shell of the inflation and deflation connector at the front end of the inner container through elastic force of the spring, and the non-outlet conical face end of the piston makes contact with the valve element. The valve element is pushed to move through the movement of the piston. According to the high-temperature-resistant self-sealing gas cylinder, the gas cylinder can work in a high-temperature environment, and the high-temperature-resistant self-sealing gas cylinder has the characteristics of being simple in structure, good in economical efficiency, small in size, light in weight and the like.

Description

technical field [0001] The invention relates to the technical field of aerospace pressure vessels, in particular to a high-temperature-resistant self-sealing gas cylinder. Background technique [0002] With the development of the aerospace field, higher requirements are put forward for the aerospace power system. Today, aerospace power systems are developing towards integration, economy, light weight, and miniaturization. Aerospace power systems use a large number of high-pressure gas cylinders, and with the exploration of deep space, the use environment is gradually becoming harsher. During the operation of the aircraft, its internal temperature will change greatly with the change of the operating time and the external environment, and it will experience high and low temperatures. There are high requirements for the reliability of the aerospace power system and the high and low temperature resistance of the parts. However, at present, most gas cylinders generally cannot wi...

Today, aerospace power systems are developing towards integration, economy, light weight, and miniaturization. Aerospace power systems use a large number of high-pressure gas cylinders, and with the exploration of deep space, the use environment is gradually becoming harsher. During the operation of the aircraft, its internal temperature will change greatly with the change of the operating time and the external environment, and it will experience high and low temperatures. There are high requirements for the reliability of the aerospace power system and the high and low temperature resistance of the parts. However, at present, most gas cylinders generally cannot withstand high temperature assessment, which brings danger to the operation of aerospace power systems.
