Problems solved by technology
[0002] When the existing metal pressure vessels are tested for tightness, most of them use pressure filling, gas shutoff, and pressure maintenance to test the tightness, and a few use sound collection. The former should be due to the deformation effect of the pressure vessel itself. The transformation has a delay, so the detection time is prolonged. The latter needs to place the metal pressure vessel in a quiet room or a static box, which is affected by external factors and makes the measurement operation difficult. Therefore, we propose a method for detecting the seal of metal pressure vessels. Sex detection device

[0023] When in use, the base cylinder 1 and the welded threaded rod 4 are effectively combined and installed with the fixed corner seat 6 and the base 7 carried by itself and the rotating threaded cylinder 8, so that the inner ring sleeve 3 is closely attached to the outer wall of the pressure vessel, and then the circuit Connect the first pressure sensor 9, the second pressure sensor 10 and the universal ammeter 5, pressurize the pressure vessel, and when the rated pressure is reached, the pressure vessel is deformed at this time, record the readings of the universal ammeter 5, and then regularly observe the universal ammeter 5 , to carry out the numerical observation, so as to carry out the tightness detection.

The invention provides a test device used for testing the sealing performance of a metal pressure vessel, the test device comprises base cylinders, inner ring sleeves and fixing corner seats, the numbers of the base cylinders, the inner ring sleeves and the fixing corner seats are four, threaded rods are welded to the two ends of each base cylinder, two bases are welded to the outer walls of the fixing corner seats and vertically distributed, rotation threaded cylinders are mounted at the outer ends of the two bases in a rotation manner, the base cylinders, the threaded rods, the rotation threaded cylinders, the bases and the fixing corner seats are connected end by end sequentially, and connection plates are welded to the inner sides of the four base cylinders; shape change is tested through change of the pressure vessel after inflation and change of the capacitance of a capacitance sensor in the test device, the operation is simple, verification of pressure delay is avoided, at the same time, the shape change of the device is only influenced by the internal pressure, the other factors are avoided, the whole process is rapid, and the verification result accuracy is high.
Description
technical field [0001] The invention relates to a detection device for detecting the tightness of a metal pressure vessel, which belongs to the technical field of detection devices. Background technique [0002] When the existing metal pressure vessels are tested for tightness, most of them use pressure filling, gas shutoff, and pressure maintenance to test the tightness, and a few use sound collection. The former should be due to the deformation effect of the pressure vessel itself. The transformation has a delay, so the detection time is prolonged. The latter needs to place the metal pressure vessel in a quiet room or a static box, which is affected by external factors and makes the measurement operation difficult. Therefore, we propose a method for detecting the seal of metal pressure vessels. sex detection device. Contents of the invention [0003] In view of the deficiencies in the prior art, the object of the present invention is to provide a detection device for de...
