Description

Technical Field

[0001] The present invention relates to the technical field of detection devices, and in particular to an intelligent butterfly valve assembly and testing all-in-one machine. Background Art

[0002] A butterfly valve is a valve that uses a disc or disk as a disc, which rotates around the valve shaft to open and close. In the cylindrical channel of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the flow is controlled by rotating the butterfly plate 90°. When the butterfly plate reaches 90°, the valve is in a fully open state. The butterfly valve is used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media, and mainly plays a cutting and throttling role in the pipeline.
