Valve routine maintenance small guide

Valves are widely used in various industries with different environments.

Valves in harsh environments are prone to problems. Repairing or replacing large valves is troublesome. Therefore, daily maintenance is very important. Specific measures include the storage and daily inspection of valves. For example, they should be stored in a dry and ventilated room with both ends of the passage blocked. Valves stored for a long time should be inspected regularly and coated with anti-rust oil.

After installation, regularly check the sealing surface, thread, packing and other conditions and conduct sealing performance tests. Maintenance during valve greasing is also crucial. Attention should be paid to the greasing amount. According to the valve type, accurately calculate the sealing capacity and inject an appropriate amount of lubricant. At the same time, the greasing pressure cannot be ignored.

Too low pressure will accelerate the wear of the sealing surface. Too high pressure will lead to problems such as blockage. Different sealing forms have different greasing pressures. The greasing pressure of hard seals is higher than that of soft seals. Doing these jobs well can extend the service life of valves and reduce unnecessary troubles.
