Description

Technical Field

[0001] The present invention relates to the technical field of gas valve detection, and in particular to a large-scale gas valve visual recognition device. Background Art

[0002] Gas valves are often used in daily production and equipment use. Gas valves are components in compressors used to control the flow of gas in and out of the cylinder. They are mainly composed of valve seats, valve plates, springs and lift limiters. The lift height or closure between the valve plate and the valve seat determines the size and tightness of the gas channel.

[0003] In the prior art, when producing air valves, it is necessary to use an air valve identification device to observe whether the height and size of the air valve are qualified, and then the air valve is used normally. The traditional air valve identification device has a fixed visual camera, which may cause some air valves to be unable to be identified. At the same time, when the work vehicle providing the operation is located under the identification device, there is no limiting device, which may cause instability of the work vehicle, thereby causing the air valve to tip over, which is extremely inconvenient.
