Ceramic pneumatic valve maintenance

ceramic 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 reasonable use ceramic pneumatic valve, on the maintenance to the greatest extent, prolong its service life, is the first problem of using ceramic pneumatic valves.
ceramic pneumatic valves first 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. For you to share ceramic pneumatic valve life-extending measures.
a, clean pipeline prolong life
pipe welding slag, rust, solidification of pulp are, wire, cloth and other body parts at the throttle mouth, arc polishing machine guide causing 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.
2, increases the opening work 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, as the fluid to the destruction of the pneumatic valve core, flow rate increases, the opening of the circular arc polishing machine 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.
3, the changing structure of arc polishing machine increased life
ceramic pneumatic valve regulation initially used two chip 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.
4, transfer damage position to improve the destroyed life place 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. Five, increase the caliber life

we the formula for computing the CV value, 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.
