Ball Valve Maintenance Considerations

Ball valve has a longer service life and maintenance-free period, in addition to the normal operating conditions, harmony
The temperature / pressure ratio, and reasonable corrosion data will be dependent on factors that do the following Note:
● valve closed state, the internal body is still pressurized fluid.
● repair ball valve lift line pressure and the valve in the open position.
● ball valve maintenance, disconnect the power or gas source.
Repair, actuator and bracket from the
● must first identify the valve on the downstream pipeline, that has been dropped pressure to disassemble
● decomposition and re-assembly must be taken to prevent damage to the sealing surface of the parts, especially the non-metallic parts, take
The O-ring should use a special tool
● ball valve assembly bolts on the flange must be symmetrical, gradually and evenly tighten.
Cleaning agent should be used with ball valve, rubber parts, plastic parts, metal parts and the working medium (such as gas) are
Compatibility. The working medium is a gas, gasoline to clean metal parts. Non-metallic parts with pure water or alcohol
Clean
● break down the individual parts can be cleaned by immersion. Still left undecomposed down the the non-metallic parts
Metal parts can be clean famed for their silk cloth impregnated with a cleaning agent (in order to avoid fiber shedding adhesion on the part
) Scrub. Cleaning is required to remove all the adhesive on the wall of grease, dirt, rubber product, dust and other
Non-metallic parts should be cleaned immediately removed from the cleaning agent, not a long soak
● After washing need to be washed wall volatile cleaning agent (available not dip cleaning agent silk rub) assembly,
standard air cylinder
But shall not be shelved for a long time, otherwise it will rust, dust pollution
● new parts before assembly also need to be cleaned
● Use grease lubrication. Grease should be ball valve metal materials, rubber parts, plastic parts and the working medium
Are compatible. The working medium for the gas, can be used, for example, special 221 grease. On the surface of the seal mounting groove
Coated with a thin layer of grease, coated with a thin layer of grease on the rubber seals, valve stem sealing surface and the friction surface coating
A thin layer of grease
The assembly should be allowed to have metal debris, fibers, oils and fats (except for the requirement to use) dust and other miscellaneous
Quality, foreign body contamination, adhesion, or stay on the surface of the part or entering the chamber
