Abstract

The invention relates to a gas recycling device of a round tube high-temperature creep fatigue tester, which comprises a high-pressure gas cylinder, a furnace body, a gas treatment pool and a gas recycling bottle, wherein a round tube sample for testing is arranged in the furnace body, and a temporary gas storage bottle is arranged between the high-pressure gas cylinder and the furnace body. A pressurizing electromagnetic valve, a load electromagnetic valve and a second valve are arranged on the pipeline between the high-pressure gas cylinder and the temporary gas storage cylinder, a third valve is arranged on the pipeline between the temporary gas storage cylinder and the furnace body, and a safety valve is arranged on the pipeline between the furnace body and the gas treatment pool; and a third compressor, an air filter and a fourth valve are arranged on a pipeline between the gas treatment pool and the gas recycling bottle. The device is simple and ingenious in structure, can meet the requirements of the creep fatigue test of the pipeline, can recycle and reuse the gas after the test, and can save the cost and reduce the probability of resource waste while ensuring that the environment is not polluted.

Description

technical field [0001] The invention relates to the technical field of material performance testing, in particular to a gas circulation recovery device for a circular tube high-temperature creep fatigue tester. Background technique [0002] The development of economy and society is inseparable from the consumption of various energy sources. Pipes are widely used in nuclear power plants, chemicals, oil and gas transportation and other fields. Generally, it is operated at high temperature and high pressure, which will cause damage to the pipeline. In order to test the performance of the pipeline under different high temperature and high pressure and estimate its service life, a high temperature creep fatigue tester is built to test the proportionally manufactured pipe round pipe sample. In the creep fatigue test of pipelines, considering the convenience and economic benefits of the test, it is necessary to recover the gas for the test to facilitate reuse and save costs. [00...
