New lotoke Ball valves are widely used in many countires and are indispensable in chemical, water conservancy, electric power, steel, petroleum refining and other industries. The ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. It only needs to rotate 90° and a small torque to close tightly. There are many types of ball valves. For example, electric ball valves should pay special attention to the environmental conditions of use in addition to the pipeline parameters. Because the electric device in the electric valve is an electromechanical device, the use state is greatly affected by its use environment. So, how to extend the service life of ball valves that are used in life or in various industries, big and small?

If you want to extend the service life of the ball valve, it is very useful to know some common sense or knowledge of the valve. In order for the ball valve to have a long service life, it must rely on the following factors:

Normal working conditions

Maintain a harmonious temperature/pressure ratio

When the ball valve is closed, there is still pressurized fluid inside the valve body

Regarding disassembly, be sure to check the upstream and downstream pipes of the ball valve to make sure that the pressure has been relieved before proceeding with the disassembly and disassembly operation; when reassembling after disassembly, remember to be careful to prevent damage to the sealing surface of the parts, especially non-metallic Components. Use special tools to operate, and the bolts of the flange should be tightened symmetrically and evenly.

Regarding cleaning, the cleaning agent should be compatible with the rubber parts, plastic parts, metal parts and working medium in the ball valve. For example, when the working medium is gas, you can use gasoline to clean metal parts, and non-metallic parts can be cleaned with pure water or alcohol. When cleaning non-metallic parts, be careful not to soak them for a long time. After cleaning the parts, wait for the cleaning agent to evaporate or wipe off the cleaning agent before assembling. But it can't be put on hold for a long time, otherwise it will rust, be polluted by dust, and it will be washed in vain. Because metal chips, fibers, grease and other dust or other impurities are not allowed to adhere to the surface of the parts or enter the cavity during assembly. Also, if there is leakage at the packing, the stem nut needs to be tightened again.

Use grease, which should also be compatible with the working medium of the ball valve metal material, rubber parts, plastic parts, etc. When the working medium is gas, special grease can be used. Apply a thin layer of grease to the surface of the seal installation groove, the rubber seal, and the sealing surface of the valve stem.
