Embodiment Construction

[0037] The present invention will be further described below in conjunction with accompanying drawing:

[0038] like figure 1 As shown, a test device for testing the creep performance of a high-temperature integral flange joint is characterized in that it includes an upper flange 14 and a lower flange 22, and a test gasket 20 is loaded between the upper flange 14 and the lower flange 22, and the upper flange 14 and the lower flange 22 are loaded. The flange 14 and the lower flange 22 are arranged in the electric heating furnace 11, the upper flange 14 and the lower flange 22 are connected and fixed by the studs 12, and the upper flange 14, the lower flange 22 and the studs 12 are fixed Many places are marked with quartz optical fiber 44 to measure the deformation of the upper flange 14, the lower flange 22 and the double-ended stud 12. There is a measuring device in the gap between the end of the lower flange 22 and the double-ended stud 12. The ring 21, the test gasket 20 an...

Abstract

The invention discloses a testing device for testing creeping property of a high-temperature integral flanged joint, which includes a flanged joint, a heating and temperature control system, a worm gear transmission mechanism, a deformation measurement system, a supporting structure, a medium given system, a computer image processing system and a medium sealing system. The testing device for testing the creeping property of the high-temperature integral flanged joint provided by the invention has the advantages of compact structure, simplicity in operation, small occupied area and low cost, and solves the problem that the creeping properties of all the elements in the vacuum flanged joint cannot be measured at present.

Description

technical field [0001] The patent of the present invention relates to a test device. More specifically, a set of long-term and long-term accurate measurement of flanges and gaskets under high temperature is established by using the high temperature resistance characteristics of quartz optical fiber and advanced remote microscope and computer image processing technology. and bolt creep deformation high temperature integral flange joint creep performance test device. Background technique [0002] With the development of science and technology, the working conditions of high temperature, high pressure, flammable, highly corrosive, highly toxic and radioactive media in industrial production are increasing day by day. Once these systems leak, it will not only waste energy and materials, but also pollute the environment, and even cause serious hazards such as casualties and property losses. For this reason, modern industries, especially nuclear power, aerospace, military and oth...
