Description

Technical Field

[0001] This invention relates to the technical field of valve seat press-fitting equipment, specifically to an automatic valve seat press-fitting changeover device and its operation method. Background Technology

[0002] The valve seat is a detachable surface component inside the valve, used to support the valve core in the fully closed position and form a sealing pair. Generally, the valve seat diameter is the maximum flow diameter of the valve. For example, the valve seat materials for butterfly valves are very diverse, including various types of rubber, plastics, and metals. Valve seats come in various models, and traditional valve seat press-fitting equipment typically uses a single valve seat press-fitting assembly. This means that when pressing different models of valve seats, the valve seat press-fitting assembly needs to be disassembled and replaced first, resulting in a slow production process and affecting production efficiency. To address this issue, this invention proposes an automatic valve seat press-fitting changeover device and operating method to solve the above problems. Summary of the Invention
