1、阀门定位器需要定期维护和校准。对于关键应用，建议每季度或每半年进行一次校准检查，而对于其他过程，不太频繁的间隔可能就足够了。

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、执行器通常不需要经常维护。

2. Executors usually do not require regular maintenance.

3、隔膜、活塞环和端部密封件需要每年检查。在这些检查中，活塞式执行器气缸和O形圈应润滑。

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、对于关键过程，阀门配平必须每年进行目视检查。

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

5、弹性体装饰件和金属阀座应该每年更换一次。在不太关键的应用中，可以根据需要延长更换间隔或进行维护。

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.

控制阀的哪些部分需要定期维护？

What parts of the control valve require regular maintenance?

阀体和装饰件，包括密封件和垫圈，需要定期检查腐蚀和磨损。执行器应进行检查、润滑和校准，以确保平稳运行，同时注意弹簧、隔膜和定位器。应检查和调整阀杆，以防止泄漏。紧固件需要定期检查紧密度和腐蚀。对于气动系统，应检查和清洁或更换空气过滤器和调节器。诊断系统，如果安装，应进行监控，以及早发现潜在问题。传感器需要定期检查和校准，以确保准确测量

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
