Ceramic valve is often used in the working condition of harsh conditions, mounted on a heavy process piping, the working conditions are extremely complex, once appear problem, because of its heavy, the problem was 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 valve, on the maintenance to the greatest extent, prolong its service life, is the first problem of using ceramic valve. The following provides 5 kinds of pottery and porcelain regulator life extension method. 1, clean pipeline life extension line of welding slag, rust, lime slurry solidifying residual, wire, cloth and other body parts in throttling mouth, guide fractured cause blocked or jammed the valve core, and 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, let the valve fully open, after a period of time to let the medium flow in normal operation. 2, increase the opening work life extension in as far as possible when started using ceramic valve on the maximum opening work, such as 80%. Initial impurities in this way, the pipe erosion and wear and tear occurred outside the valve core is damaged parts, remove the impurities in the pipeline, then the valve opening to the normal opening slightly larger, as the fluid damage to the valve core, traffic increased, the opening of the reduced accordingly to such damage, gradually close, make whole all make full use of the Industrial Valves core, until the valve core roots and sealing surface damage, cannot use. 3, increase the diameter increased with the formula for computing the CV value, we calculate the correct CV to choose suitable for optimum diameter of the valve. In the case of the same flow rate, the valve diameter is smaller, the faster the fluid velocity, medium of valve core and seal the erosion of the more powerful. Suggest user within the scope of the freedom to opening adjustment, appropriately increasing the diameter of the valve, which have the effect of reducing wear and tear. 4, transfer damage position to improve the destroyed life place transferred to a secondary position, with protection Industrial Valves core seat sealing surface and the surface of the throttle. Ceramic ball valve of the most serious erosion, usually the fastest part of fluid velocity is the bottom of the imported parts, fluid in ceramic ball valve now three panel structure, can use the ball core commutation, so a ball core can be used in the inlet four times, four times prolongs the service life of the valve. 5, change the valve structure to improve the life ceramic valve initially two type structure, for the valve structure more reasonable, changed now commonly used three panel structure, this kind of structure with double seat, therefore also has the characteristics of the double seal. At the same time, pay attention to choose to have when use ceramic ball cant transition design of the valve, the valve to reduce the impact of the fluid.
