Abstract

The invention discloses an expansion joint failure test device comprising a left pipeline and a right pipeline, a pipeline left flange which is connected with the left pipeline, a pipeline right flange which is connected with the right pipeline and an expansion joint which is connected between the pipeline left flange and the pipeline right flange through a bolt and a gasket. The non-connection ends of the left pipeline and the right pipeline are sealed and a sealing cavity is internally formed. A heating mechanism is arranged in the sealing cavity. The sealing cavity is externally provided with a high pressure gas tank. The high pressure gas tank is connected with a balance valve and a flowmeter in turn through the pipeline and finally communicated with the sealing cavity. The expansion joint failure test device is simple in structure and convenient to operate so that the phenomenon of leakage of the expansion joint connection system can be detected and the leakage rate of the expansion joint connection system can also be accurately calculated.

Description

technical field [0001] The invention relates to a failure test device for an expansion joint. Background technique [0002] The expansion joint is a flexible structure arranged on the container shell or pipeline to compensate for the additional stress caused by temperature difference and mechanical vibration. Utilize the effective expansion and contraction deformation of the working body of the expansion joint to absorb the dimensional changes of pipelines, conduits, containers, etc. due to thermal expansion and contraction, or to compensate for the axial, lateral, and angular displacement of pipelines, conduits, containers, etc. Can be used for noise reduction and vibration reduction. Has been widely used in environmental protection, chemical industry, metallurgy and other fields. In the field of environmental protection, in order to prevent the pipe from being deformed or damaged due to thermal elongation or temperature stress when the heating pipe heats up, it is necess...
