How to prolong the service life of ceramic balls pneumatic valve

ceramic ball pneumatic valve is often used in the working condition of harsh conditions, on the heavy process piping installation, working conditions are extremely complex, once appear problem, because of its heavy, problems are hard to find, often let a person helpless, also involves the system put into operation, the system complete, control quality, environmental pollution and other issues, so the rational use of ceramic ball pneumatic valve, on the maintenance to the greatest extent, prolong its service life, is to use ceramic ball this the prime problem of the pneumatic valve.
the following provides a kind of ceramic ball pneumatic valve life extension method.
, cleaning pipe prolong life
pipeline welding slag, rust, lime slurry solidifying residual, wire, cloth, etc. At the throttle mouth, guide part cause blocked or jammed the pneumatic valve core fracture, often occur in the early new operation system and put into operation after overhaul. This is the most common fault. Encounter this situation, it is necessary to remove for cleaning, remove the slag content, such as the sealing surface damage should also grinding; Open the bottom plug at the same time, in order to develop residue, and the pipeline to wash. Before put into operation, to adjust the pneumatic valve fully open, after a period of time to let the medium flow in normal operation.
work, increase the opening prolong life
when begin to use ceramic ball pneumatic valve as far as possible on the biggest opening work, such as %. Initial impurities in this way, the pipe erosion and wear and tear occurred in pneumatic valve core is damaged part outside, remove the impurities in the pipeline, then adjust the opening of pneumatic valve adjusting to normal opening slightly larger, with fluid to the destruction of the pneumatic valve core, the flow rate increased, the opening of the reduced accordingly to such damage, gradually closed, all make full use of the whole pneumatic valve core, until the pneumatic valve core roots and sealing surface damage, cannot use.
,
we increase the diameter life by CV value calculation formula, calculates the right CV to choose suitable for optimum pneumatic valve diameter. Under the condition of the same flow, pneumatic valve diameter is smaller, the faster the fluid velocity, medium erosion of pneumatic valve core and seals will be severe. Suggest user within the scope of the freedom to opening regulation, appropriate increase the calibre of the pneumatic valves, which have the effect of reducing wear and tear.
damage location, transfer improves life
the destroyed places transferred to a secondary position, in order to protect the pneumatic valve core seat sealing surface and the surface of the throttle. Ceramic ball pneumatic valve usually the most serious erosion, the fastest part of fluid velocity is the bottom of the imported parts, fluid for ceramic ball now three chip structure, pneumatic valve ball core reversing can be used, so a ball core can be used in the inlet four times, prolongs the service life of pneumatic valve.
and the changing structure of pneumatic valve to improve life
the ceramic ball pneumatic valve initially two type structure, in order to pneumatic valve's structure more reasonable, changed now commonly used three panel structure, this structure with double pneumatic valve seat, therefore also has the characteristics of the double seal. At the same time, pay attention to choose when to choose ceramic ball pneumatic valve cant have transition design of pneumatic valve, it can reduce the impact of the fluid.
