Maintenance and maintenance of copper valve packing

Remarks: During the switching process of the copper valve , the original added lubricating grease will be continuously lost, and the temperature, corrosion and other factors will also cause the lubricating oil to dry continuously. Therefore, the transmission part of the valve should be checked frequently, and it is found that the lack of oil should be replenished in time to prevent the loss of wear due to the lack of lubricant, resulting in inflexible transmission or failure of the casing.
