Strict control of dimensional accuracy and surface roughness is required during machining to ensure good line contact between the sealing surface and the valve seat. Therefore, matching equipment is needed for machining. A search of application CN202411966633.8 discloses a machining fixture for the sealing surface of a triple eccentric butterfly valve body, which includes a swashplate and a positioning plate. The swashplate includes a connected top plate and a bottom plate, the angle between which is set according to the angle between the valve body axis and the valve seat cone axis. The positioning plate is connected to the top plate.
