Ceramic adjust life extension pneumatic valve 5 ways

ceramic adjust working condition of pneumatic valve is often used in 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 reasonable use ceramic pneumatic valve adjustment, on the maintenance to the greatest extent, prolong its service life, is to use ceramic to adjust the prime problem of the pneumatic valve.

the following provides a kind of ceramic adjustable pneumatic valve to extend the life of the method.

, cleaning pipe prolong life

in the 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

in the beginning as far as possible when using ceramic regulating pneumatic valve on the maximum 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.

, increasing the diameter increased with the

the formula for computing the CV value, we calculate the correct 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 regulating 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 valves, such as regulating pneumatic valve to reduce the impact of the fluid.
