Description

Technical Field

[0001] The utility model relates to the technical field of detection and calibration platforms, in particular to a pressure gauge detection and calibration platform. Background Art

[0002] A pressure gauge calibration bench is a device used to calibrate and verify the accuracy of various types of pressure gauges. It can generate a known pressure through a standard pressure source and compare it with the pressure gauge being calibrated to confirm whether its reading is accurate.

[0003] In the prior art, when the pressure gauge is being tested, it is necessary to threadably install the pressure gauge and the pipe opening on the top of the calibration bench. When not in use, the pipe opening is blocked with a plug to prevent dust from entering. However, in actual use, dust will be present on the surface of the test and calibration bench when it is placed, and the dust will also adhere to the outside of the pipe and the surface of the plug. When the plug is removed, dust will float into the inside of the pipe, affecting the detection accuracy of the test and calibration bench. Therefore, it is necessary to improve a pressure gauge test and calibration bench to solve the above problems. Utility Model Content

[0014] 1. The pressure gauge detection and calibration bench is equipped with an independent flip-up mechanism. During use, the support frame can be fixed by means of an insert rod and a spring, and the independent dust cover can be fixed. When a small number of docking pipes need to be used, the independent dust cover can be flipped over to select and use the docking pipes, so as to prevent the remaining docking pipes from being exposed to the air and excessively adhering to dust. The air blowing airbag body is used to blow air on the surfaces of the docking pipe and the threaded plug, which can blow away the tiny dust on the surfaces of the docking pipe and the threaded plug to prevent it from adhering to the outside and prevent dust from floating into the inside of the docking pipe when the threaded plug is unscrewed, thereby ensuring the detection accuracy of the detection and calibration bench body.
