The invention discloses a high-temperature-resistant and high-pressure-resistant gas hose, and relates to a metal hose. The high-temperature-resistant and high-pressure-resistant gas hose comprises an input pipe joint, a plurality of section pipes which are connected end to end in a sleeving mode to form a pipe body of the gas hose, a plurality of halving pressing rings which are assembled at the connecting part of the plurality of section pipes and used for connecting the plurality of section pipes, an output pipe joint, and a plurality of clamping hoops, wherein a front ball head of an output pipe is connected with the section pipes in a sleeving mode, and a rear connecting part is fixedly connected with a gas output device to form an airtight pipeline; and the plurality of clamping hoops cover the plurality of halving pressing rings and third inclined convex parts, and are used for fastening each connecting part of the gas hose. According to the invention, a pipeline composed of front ball heads and rear ball heads of the plurality of section pipes, the halving pressing rings and the hoops can freely rotate within a certain angle range in any direction, and the front end of a continuous spherical surface composed of the inner side surfaces of the halving pressing rings and the front end of each front ball head exceeds the spherical center position of the spherical surface, so that the contact fit of the spherical surface cannot be separated during working after assembling.
Description
technical field [0001] The invention belongs to the technical field of metal hoses, in particular to a high temperature and high pressure resistant gas hose. Background technique [0002] With the development and progress of my country's aviation industry, more and more aircraft are designed and put into use. In the design process of modern high-design index fighter jets, it is necessary to conduct experiments to explore the aeroengine's air-stop restart capability and its impact on fighter jets in various attitudes. Since the starter of the aero-engine used in fighter jets is a small turbine engine, a large amount of high-temperature and high-pressure gas is required to simulate the aero-engine's ability to restart in the air under various attitudes of the fighter jet and the influence of intake and exhaust on the fighter jet when the starter is working. Engine starter exhaust, because there are various postures when fighter jets start, so the high-temperature and high-pre...
