Description

Technical Field

[0001] The utility model relates to the technical field of pressure instrument movement, in particular to a quality detection device for processing pressure instrument movement. Background Art

[0002] The pressure gauge movement can convert the linear displacement of the free end of the spring tube into angular displacement, so that the small displacement of the spring tube is amplified, so that the pointer obtains a larger rotation angle proportional to the measured pressure, so as to ensure that the pressure gauge has sufficient reading accuracy and achieve the purpose of easily observing the indicated value. The pressure gauge movement is the main work object in the pressure gauge maintenance. It is the root cause of the pressure gauge failure and error. The maintenance personnel should have a full understanding of it and need to test the pressure instrument movement to check whether the pressure instrument movement meets the processing standards. For example, the patent subject "A household gas meter movement leakage detection device", application number "201420782983.4", can detect gas meter movement leakage under semi-automatic conditions, and use instruments to judge the leakage situation, which reduces the complexity and difficulty of operation and improves the detection quality. However, it cannot guide the connecting end of the gas guide tube. When the detected pressure instrument movement leaks during swinging, the leaked gas is easy to diffuse, reducing the detection efficiency. Utility Model Content

When the movement of the pressure instrument is tested, the streamer 15 is distributed on both sides of the pressure instrument to be tested, and the valve connected to the pressure gas tank 4 is opened. After the internal gas of the pressure gas tank 4 is passed into the interior of the pressure instrument through the air guide tube 5, check whether the streamer 15 swings, and detect whether the pressure instrument has leakage.
