When maintaining and servicing high-temperature valves in high temperature environments, special attention should be paid to the following aspects:
1. * * Selection and Installation * *: Select the appropriate type and material of high-temperature valve, such as high-temperature alloy steel or ceramic, and install it correctly according to the manufacturer's instructions. When installing, the direction and position of the valve should be considered to ensure that it can work properly and avoid displacement or misalignment caused by temperature changes.
2. * * Operating precautions * *: When operating high-temperature valves, frequent opening and closing should be avoided to prevent wear on the valve stem. At the same time, pay attention to the temperature range of the valve and do not exceed its temperature limit.
3. * * Regular Inspection and Maintenance * *: Regularly check the sealing performance and working condition of the valve, and carry out necessary maintenance and repair in a timely manner. Check whether the packing is aging or damaged, and replace it in a timely manner. For the trapezoidal thread of the valve stem and valve stem nut, lubricant should be added regularly to prevent biting.
4. * * Cleaning and Dust Prevention * *: Regularly clean the valve to remove dust and dirt, in order to prevent affecting the normal opening and closing of the valve. For outdoor valves, special attention should be paid to rain, snow, and dust erosion.
5. * * Hot Tightening * *: For high-temperature valves above 200 ℃, the increase in temperature may lead to an increase in bolt clearance, and a "hot tightening" operation should be performed to ensure the tightness of the connection.
6. * * Lubricating maintenance * *: When filling the valve with grease, pay attention to the amount and pressure of the grease, ensure that the lubricating grease is evenly distributed, and avoid excess or insufficient. After grease injection, the grease injection port should be sealed and rust proof grease should be applied to prevent grease oxidation and rusting.
7. * * Special Operations * *: For high-temperature valves, special operations such as hot tightening bolts may be required at high temperatures. These operations should be performed by experienced technicians and follow safety operating procedures.
8. Material selection: The material selection for high-temperature valves should consider their stability and corrosion resistance at high temperatures to ensure long-term stable operation of the valve.
By following these maintenance and upkeep measures, the reliability and safety of high-temperature valves can be ensured in high-temperature environments, extending their service life.
