What Are the Maintenance Requirements for a Drilling Equipment Valve?

The maintenance of Drilling Equipment Valve is essential to ensure the normal operation and safe production of drilling equipment.
In daily maintenance, the appearance of the valve should be checked regularly to check for defects such as wear, corrosion, and cracks. For valve components exposed to the external environment, such as valve stems and hand wheels, dirt and debris on the surface should be cleaned in time to prevent them from entering the valve and affecting the sealing performance and operational flexibility. At the same time, check the connection parts of the valve to ensure that the bolts, nuts and other connectors are tightened and not loose, so as to avoid leakage during the drilling process.
The sealing performance of the valve is the focus of maintenance. Regularly check whether the sealing surface is damaged, deformed or aged. If there is a problem, the seal should be replaced in time. For some valves using rubber seals, pay attention to the aging of the rubber, because the aged rubber seals will lose elasticity and cause the seal to fail. In addition, the sealing performance of the valve can be tested by pressure testing and other methods to ensure that there is no leakage under working pressure.
Lubrication is also a key maintenance link. According to the equipment manufacturer's recommendations, regularly add an appropriate amount of lubricant to the moving parts of the valve, such as the threaded parts of the valve stem, bearings, etc. Appropriate lubricants can reduce friction between parts, reduce wear, and ensure smooth opening and closing of the valve. At the same time, pay attention to the quality and type of lubricants, and select appropriate lubricants according to the working environment and medium of the valve to avoid affecting the performance of the valve due to the reaction between the lubricant and the medium.
In addition, the valve should be regularly tested for function to check whether the valve's opening and closing action is flexible and whether the limit device is accurate and reliable. For some valves with automatic control functions, it is also necessary to test their linkage with the control system to ensure that they can respond to control instructions in a timely and accurate manner when needed. If the valve is found to be abnormal or stuck during the test, it should be repaired or adjusted in time.
