Maintenance method of Manual Knife Gate Valve

Maintenance method of Manual Knife Gate Valve

The maintenance of manual gate valve is the key to confirm its normal operation and prolong its service life.Here are some basic maintenance methods:

Regularly check the working condition:check whether the valve has leakage,whether the valve cover is loose,etc.,and serve the problem with care in time.

Check the sealing performance:check whether the valve leaks by observation and hearing,and adjust the gasket or replace the seal when necessary.

Regular cleaning:clean the inside and outside of the valve to avoid blockage and corrosion,use neutral detergent or clean water,and avoid using strong acid and alkaline cleaning agents.

Lubricating moving parts:lubricate the moving parts such as bearings and swing rods,and use lubricating oil or grease to keep the flexibility of the valve.

Operation test:Conduct the operation test of the valve regularly to confirm the normal opening and closing actions and check whether the sealing performance is good.

Anti-corrosion(mainly based on actual report)(mainly based on actual report)measures:in humid environment,adopt antirust agent or surface coating to protect the valve to avoid corrosion.

Pay attention to transportation and installation:when transporting and installing the Manual Knife Gate Valve,prevent the valve from being hit or damaged,and confirm the correct installation.

Long-term storage:if the valve is not used for a long time,it should be closed and kept dry,and it should be stored in a ventilated and dry place indoors.

When performing these maintenance steps,you should follow the specific instructions and product instructions of the valve manufacturer to confirm the good maintenance effect.
