Technical Field
[0001] The utility model relates to the technical field of valve body chamfering processing, in particular to a chamfering device for a flange hole on the back side of a valve body. Background Art
[0002] To facilitate the installation of the valve body, a flange is machined on the valve body at the same time. The flange has two flange holes. In the existing technology, the flange holes need to be chamfered after the valve body is machined. However, the space between the flange hole on the back of the valve body and the valve body is narrow. A common drill bit cannot reach the flange hole on the back of the valve body, making it impossible to properly chamfer the flange hole on the back of the valve body. Therefore, a chamfering device for the flange hole on the back of the valve body is proposed to facilitate chamfering the flange hole on the back of the valve body. Summary of the Invention
