1、閥門定位器需要定期維護和校準。對于關鍵應用，建議每季度或每半年進行一次校準檢查，而對于其他過程，不太頻繁的間隔可能就足夠了。

1. Valve positioners require regular maintenance and calibration. For critical applications, it is recommended to conduct calibration checks every quarter or six months, while for other processes, less frequent intervals may be sufficient.

2、執行器通常不需要經常維護。

2. Executors usually do not require regular maintenance.

3、隔膜、活塞環和端部密封件需要每年檢查。在這些檢查中，活塞式執行器氣缸和O形圈應潤滑。

3. Diaphragms, piston rings, and end seals need to be inspected annually. In these checks, the piston actuator cylinder and O-ring should be lubricated.

4、對于關鍵過程，閥門配平必須每年進行目視檢查。

4. For critical processes, valve balancing must be visually inspected annually.

5、彈性體裝飾件和金屬閥座應該每年更換一次。在不太關鍵的應用中，可以根據需要延長更換間隔或進行維護。

5. Elastic body decorations and metal valve seats should be replaced once a year. In less critical applications, replacement intervals can be extended or maintenance can be carried out as needed.

控制閥的哪些部分需要定期維護？

What parts of the control valve require regular maintenance?

閥體和裝飾件，包括密封件和墊圈，需要定期檢查腐蝕和磨損。執行器應進行檢查、潤滑和校準，以確保平穩運行，同時注意彈簧、隔膜和定位器。應檢查和調整閥桿，以防止泄漏。緊固件需要定期檢查緊密度和腐蝕。對于氣動系統，應檢查和清潔或更換空氣過濾器和調節器。診斷系統，如果安裝，應進行監控，以及早發現潛在問題。傳感器需要定期檢查和校準，以確保準確測量

The valve body and decorative components, including seals and gaskets, require regular inspection for corrosion and wear. The actuator should be inspected, lubricated, and calibrated to ensure smooth operation, while paying attention to the spring, diaphragm, and locator. The valve stem should be inspected and adjusted to prevent leakage. Fasteners need to be regularly checked for tightness and corrosion. For pneumatic systems, air filters and regulators should be inspected and cleaned or replaced. The diagnostic system, if installed, should be monitored and potential issues should be detected early. Sensors need to be regularly checked and calibrated to ensure accurate measurement
