Ceramic control valve is often used in case of adverse conditions, the technology installed in various pipelines, the working conditions is extremely complex, if there are problems with their bulky, difficult to identify the problem, people are often at a loss, but also put into operation system, system integrity, regulation of quality, environmental issues such as the rational use of ceramic valve to maximize their maintenance, extending its life, the use of ceramic valve is the primary problem.
Provided the following five kinds of ceramic control valve to extend the life expectancy method.
1, cleaning to extend the life of pipeline
Pipe welding in the slag, rust, lime slurry solidification of the waste products, wire, cloth, etc. to reduce expenditures, the mouth, causing the site-oriented plug or valve core to make fragments stuck, often put into operation in the new system and put into operation after overhaul early. This is the most common fault. In such cases, the washing must be disposed of opening, with the exception of掉渣objects, such as the sealing surface should be abrasive damage; At the same time will open at the end of Sierra Leone to掉渣red objects, and to flush pipe. Put into operation, let full-regulating valve, so that for some time before the mobile medium into normal operation.
2, increasing the work of opening the extension of life expectancy
At the beginning when the use of ceramic valve opening as far as working on the largest, such as 80%. In this way, the impurities in the initial tube erosion, wear and other damage occurred in the damaged valve core part outside the pipe to remove the impurities, the regulating valve and then adjust the opening slightly larger than normal opening of the local , with the fluid on the spool of the damage, increased traffic flow, reduce the corresponding opening so that the destruction continued, and gradually shut down, so take full advantage of all of the spool until the spool and the sealing surface root damage, can not be used so far.
3, increasing the diameter to increase life expectancy
We calculated the value of CV, CV is calculated in order to choose the correct valve for proper caliber. Flow in the same circumstances, the smaller the valve diameter, fluid flow rate the faster the medium on the spool and seals are also more severe erosion. The proposed opening of the user can adjust the scope of freedom, the appropriate valve size increase, thus play a role in reducing the wear and tear.
4, the transfer of damage location to enhance life
The destruction of the local transfer to a secondary position, to protect the valve core and valve seat sealing surface of the cutting surface. Ceramic ball valve is usually the most serious erosion, fluid is the fastest growing fluid beneath the site of imports, for now 3 ceramic ball valve structure can be the core for the ball to use, so a ball can import Office Core the use of four, so that the valve 4 times longer life.
5, to change the valve structure to improve life expectancy
Ceramic control valve using the first two structures, in order to more rational structure of the valve, into the now commonly used 3-type structure, such a structure because of its dual-seat, it also has the characteristics of a double seal. At the same time, ceramic ball valve in the selection of choice when the attention of the transition slope of valve design, this valve can reduce the impact of fluid.
