Description

technical field [0001] The present invention relates to the technical field of pressure vessel detection, in particular to a deformation detection mechanism, a pressure vessel detection device and a detection system. Background technique [0002] Pressure vessel refers to a closed device that contains gas or liquid and carries a certain pressure. Since the pressure vessel will be subjected to a certain pressure during use, if the quality of the pressure vessel does not meet the standard of use, the pressure vessel may occur during use. The explosion will affect the safety of the user; therefore, the pressure vessel must undergo a pressure test before it is officially put into use, and it can be used only after the test is passed. [0003] At present, when testing pressure vessels, most of them use water as the test medium; the specific use method is: pass water into the pressure vessel and pressurize it until the pressure in the pressure vessel reaches the set value, and obs...

Problems solved by technology

[0007] In view of the above-mentioned related technologies, the inventor believes that the strain gauge needs to be pasted on the outer peripheral surface of the pressure vessel by the operator, and wrinkles are prone to appear after bonding; moreover, when pressurized, the end surface of the pressure vessel will also be deformed, thereby causing The signal value compensated by the compensation sheet is inaccurate; thus, the deformation error of the pressure vessel measured by the stress sheet is extremely large, so that the pressure vessel still has the risk of explosion during the detection process
