[0002] The butterfly valve has a simple structure, small size, light weight, and is composed of only a few parts. It can be quickly opened and closed by rotating 90°, and the operation is simple. At the same time, the valve has good fluid control characteristics. During the processing of the flange butterfly valve, the center hole of the flange butterfly valve needs to be processed using a processing device. There are at least the following disadvantages in the use of the existing flange butterfly valve center hole processing device: 1. When the existing equipment is in use, the flange butterfly valve will be clamped on the left and right, but the stability is poor when processing the center hole; 2. When the existing equipment is in use, the flange butterfly valve will be clamped and fixed, but the process is cumbersome, which prolongs the processing time of the flange butterfly valve center hole. Therefore, we have introduced a new flange butterfly valve center hole processing device. Utility Model Content
