Angular stroke actuator and valve stem connection structure and failure determination method
By modifying the connection structure between the angular stroke actuator and the valve stem and the fault diagnosis method, and by utilizing the design of a truncated cone and a spring pin, the problem of difficulty in separating the actuator from the valve and the need for disassembly for fault diagnosis in the existing technology is solved, thus achieving rapid and accurate fault diagnosis.

AI Technical Summary
When existing angular stroke valves malfunction, the actuator and valve are not easily separated, making it difficult to diagnose the fault in a timely manner. Disassembly is required for fault diagnosis, and the location of the fault is difficult to determine without direct observation.
The valve stem is connected to the angular stroke actuator, which includes a valve stem connection and an actuator connection. Through the design of the truncated cone and pressure plate, combined with the spring pin structure, a semi-disassembly fault diagnosis is achieved, and the fault location is determined by the rotation state of the actuator.
It enables rapid fault location determination without complete disassembly, reducing the frequency of disassembly and improving the efficiency and accuracy of fault diagnosis.
