Description

Technical Field

[0002] In the field of industrial manufacturing, as a key component for fluid control, the quality and performance of a control valve are directly related to the stability and safety of the entire production system; and the grinding quality of the inner wall and the base surface of the valve body is one of the important factors affecting the performance of the control valve. It not only affects the flow characteristics of the fluid inside the valve body, but also is closely related to the sealing performance, wear resistance, and corrosion resistance of the valve body.

[0003] When the existing valve body grinding device faces a valve body with a T-shaped structure and three ports, it is not convenient to horizontally fix it according to the actual specifications of the valve body, resulting in the centers of the three ports of the valve body not being on the same horizontal plane. After grinding one port and the inner wall of the valve body, in order to process other ports and the inner wall, the staff has to repeatedly disassemble and refix the valve body; each disassembly and fixation process not only consumes a large amount of time and energy, but also increases the complexity and error risk of the operation, resulting in low efficiency of the entire grinding process and unable to meet the requirements of modern industrial production for high-efficiency and precise processing.

[0015] Beneficial effects 1.
