Technical Field

[0001] This utility model belongs to the field of butterfly valve manufacturing technology, and in particular relates to a burr removal and polishing device for butterfly valve manufacturing. Background Technology

[0002] A butterfly valve, also known as a flap valve, is a simple regulating valve that can be used for on / off control of low-pressure pipeline media. A butterfly valve is a type of valve whose closing element is a disc that rotates around the valve shaft to achieve opening and closing.

[0003] During the manufacturing process of butterfly valves, burrs may appear on their inner walls. To smooth the inner walls, manual grinding is performed, which not only increases the workload but also reduces efficiency. Therefore, we provide a burr-removing device for butterfly valve manufacturing to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a burr-removing device for butterfly valve production. By using two grinding rollers and rotating them in opposite directions to the butterfly valve body, the grinding efficiency and effect are improved, the amount of manual labor is reduced, and production efficiency is increased. This solves the problem that in the existing butterfly valve production process, burrs exist on the inner wall of the butterfly valve. In order to make the inner wall of the butterfly valve smooth, manual grinding of the inner wall of the butterfly valve is required, which not only increases the amount of manual grinding work but also reduces grinding efficiency.

Then, the two first motors are controlled to drive the grinding rollers to rotate, so that the rotation direction of the grinding rollers moves in the same direction as the rotation direction of the butterfly valve body. The grinding assembly is further controlled to move into the butterfly valve body, and in coordination with the rotation of the two grinding rollers, the inner wall of the butterfly valve body is ground.

[0026] The operation process of this embodiment is as follows: The butterfly valve body 202 is placed inside the annular tube 201 and fixed.
