Description

Technical Field

[0001] The utility model relates to the technical field of pressure vessels, in particular to a bracket for central exposure of gamma ray nondestructive testing of steel pressure vessels. Background Art

[0002] A pressure vessel is a sealed device that contains gas or liquid and bears a certain pressure. In order to more effectively implement scientific management and safety inspection, the existing non-destructive testing of pressure vessels usually uses manual measurement and pressing to measure the pressure of the pressure vessel.

[0003] A central exposure bracket for nondestructive testing of pressure vessels disclosed in Chinese utility model patent application CN212321574U relates to the technical field of nondestructive testing equipment for pressure vessels, and includes a pressure vessel and a positioning ring arranged in the pressure vessel, the positioning ring is provided with a detection mechanism for detecting the pressure vessel, the detection mechanism includes three sleeves fixedly connected to the side wall of the positioning ring, the three sleeve side walls are all penetrated by a shrinking tube, the three shrinking tube side walls are all fixedly connected with a tightening block, and the positioning ring is provided with a fixing mechanism for fixing the detection equipment. The utility model enables the central exposure bracket to adapt to the detection of pressure vessels with different inner diameters, further expanding the scope of application of the device, and in addition, by increasing the friction between the tightening block and the inner wall of the pressure vessel, the shrinking tube is more firmly pressed against the inner wall of the pressure vessel, preventing the bracket position from shifting during the measurement process.

[0004] However, the existing technology lacks the function of manual rotation testing. In actual testing, the handheld test instrument's measurement is inaccurate due to inaccurate precision and force control, and the test numerical results are not precise, resulting in the inability of the existing technology to test situations of pressure and damage.

[0005] In addition, the existing technology lacks the function of positioning and fixing. In actual testing, the test pressure cannot stay in the same position for a long time to apply pressure. It can only test the instantaneous pressure and cannot test the bearing time continuously, which leads to the limitations of the existing technology. Utility Model Content
